Category: Client-Side Security

Is Generative AI (GenAI) a victim of its success? This consumer-friendly subset of AI has quickly become embedded in our daily lives. Amid this uptake, and subsequent expansion of the cyberattack surface, the GenAI revolution demands increased client-side protection and compliance to mitigate a common trend: cybercriminals’ determination to target successful new technologies that present fresh vulnerabilities.

What better way to define GenAI than to ask ChatGPT (a form of generative AI that helps with content creation and information retrieval) – the poster child for this disruptive technology – to do it for you? Here’s the answer: “GenAI, short for Generative Artificial Intelligence, refers to a category of artificial intelligence systems designed to generate new content. This content can include text, images, audio, and even code, based on patterns and data it has been trained on.”

The crucial fact ChatGPT forgot to mention is that these requests, which might take a human hour to complete, are performed in a matter of seconds – a supercharged convenience that’s prompted widespread and rapid adoption: 55% of organizations are in piloting or production mode with Generative AI, signaling a surge in GenAI integration.

Generative AI: The Benefits

Like any good technology, GenAI offers the ability to speed up jobs and processes that currently consume time and resources – and for businesses and consumers the benefits are compelling, including:

Businesses

GenAI can provide round-the-clock assistance via tools like chatbots and voice bots, addressing queries and resolving issues promptly.

Financial management

GenAI can help users manage their finances, track spending, and plan budgets. It can also provide personalized investment advice and financial insights.

Generative AI: The Security Risks

The more businesses empower customers to leverage the benefits of GenAI by integrating it into applications and processes, the more client-side protection and compliance become a consideration amid the proliferation of cyber-attacks targeting it.
 

Like most new technologies that enhance consumer convenience online, GenAI has attracted close attention from cybercriminals. These nefarious groups and individuals are developing new tools and techniques, and tweaking existing ones, to target vulnerabilities on the client side, including:

Phishing

By weaponizing generative AI and the large language models (LLMs) that underpin them, cybercriminals can scale their phishing attacks with greater speed and complexity than ever before. Not only does this allow them to compromise more data; but it also helps them avoid detection more easily.

Cross-site Scripting (XSS)

Injecting malicious scripts into GenAI-powered web pages viewed by other users can lead to unauthorized actions performed on behalf of the user or theft of session tokens and cookies to gain unauthorized access to the system – compromising data security.

Session Hijacking

This can occur through methods like man-in-the-middle attacks (MitM) or cookie theft. MitM attacks occur when cybercriminals intercept and alter communication between the client and the GenAI service, leading to data tampering or eavesdropping on sensitive information.

Browser Fingerprinting

Collecting detailed information about a user’s specific browser and device configuration to track and profile them. This information can be used to target individuals with more precision in further attacks.

Malicious Plugins or Extensions

Exploiting browser plugins or extensions to manipulate or steal data processed by the GenAI applications. Malicious extensions can capture keystrokes, screen data, or modify the behavior of web applications.

GenAI and Client-side Protection

Against this backdrop of unauthorized access, data breaches, and manipulation of AI models, there’s a growing recognition of the need for client-side protection: 91% of organizations recognize they need to do more to reassure their customers that their data is being used only for intended and legitimate purposes in AI.

To achieve this, they must prioritize key cybersecurity factors: 

1. Data privacy

GenAI systems typically rely on large datasets, bringing the privacy of client data into sharp focus for businesses. This includes implementing robust encryption, secure storage, and data anonymization techniques to protect sensitive customer information from unauthorized access and breaches.

2. Security threats

As GenAI technologies evolve and become increasingly integrated into our daily lives, they become potential targets for cyberattacks. Ensuring strong cybersecurity measures, including regular vulnerability assessments and updates, is essential to protect against client-side attacks.

3. User authentication

Strengthening user authentication mechanisms, such as multi-factor authentication (MFA) and biometric verification, helps ensure that only authorized users can access GenAI systems and the data they handle.

4. Ethical use

Ensuring that GenAI systems are used morally correctly involves setting clear guidelines and monitoring for potential misuse like generating deepfakes, misinformation, or biased content.

GenAI and Client-side Compliance

There needs to be more than technical client-side protection measures. They must be augmented by regulatory compliance to foster trust in GenAI among users and stakeholders. By understanding the regulations that govern GenAI deployment and management, organizations can adopt a proactive approach to compliance.  

Data protection 

Organizations must comply with various regulations and standards related to data protection depending on their location, such as GDPR in the EU and UK, CCPA in California, and HIPAA across the US. This includes conducting regular audits, maintaining transparency about data usage, and ensuring that data processing practices align with legal requirements.

Industry standards

Adhering to industry-specific standards and best practices is critical. For example, in the healthcare sector, compliance with standards like HL7 and FHIR ensures the secure and standardized exchange of health information.

Transparency and accountability

Implementing transparent policies and procedures for the proper development, deployment, and use of GenAI technologies in line with regulations and standards is essential. Organizations should establish accountability frameworks to ensure all stakeholders, including developers, users, and regulators, understand how these systems work and can trust their outputs.

Bias and fairness 

Ensuring that GenAI systems are fair and unbiased is crucial to achieving compliance with ethical standards and regulations. This involves regularly testing and updating models to identify and mitigate biases that may arise from the training data or the algorithms themselves.

Comprehensive GenAI security and defense strategy

Client-side protection and regulatory compliance are key components of a comprehensive and proactive GenAI security strategy. Their value has been amplified and accelerated by the rapid evolution and adoption of this transformative technology.

Working in tandem, they create a safer, more reliable, and ethical environment for the development and deployment of GenAI systems. This synergy not only protects sensitive data and ensures legal adherence; it fosters user trust and promotes the ethical use of associated technologies.

The evolution of the financial services industry has seen bricks replaced by clicks as our reliance on the internet becomes all-consuming. To keep pace with this shift online, the integration of digital technologies and data-driven solutions has become a strategic imperative for dynamic organizations in the sector.

In a bid to remain competitive, meet evolving customer expectations, and drive operational efficiency, traditional brick-and-mortar infrastructure has given way to online banking, mobile apps, and contactless payments – making digital data the lifeblood of the industry.

The provision of this online convenience comes with a huge responsibility for financial service providers: they must ensure the deluge of customer data they handle in the ordinary course of business is not misused or accessed without authorization.

Failure to do so, leading to the accidental or unlawful destruction, loss, alteration, or unauthorized disclosure of, or access to, personal data, can result in serious consequences – notably, reputational damage and financial penalties for non-compliance amid an increasingly stringent regulatory environment. 

Consequently, data privacy has been shoved to the top of the corporate agenda for firms in the sector. This touchstone of reputability provides consumers with the trust they crave when sharing their personal information. This data privacy guide will help develop your understanding of this essential discipline within the financial services industry.

Data privacy in financial services: what is it and what needs protecting?

According to IBM, “Data privacy, also called ‘information privacy’, is the principle that a person should have control over their personal data, including the ability to decide how organizations collect, store, and use their data.”

Data privacy within the financial services space refers to the protection of personally identifiable information (PII) from misuse or unauthorized access. PII in the context of the industry typically refers to any data that can be used to identify an individual in relation to their financial affairs. This includes:

• Personal information: Full name, home address, and date of birth.

• Contact Information: Phone numbers, email addresses, and sometimes social media handles.

• Identification Numbers: National Insurance number (UK), Social Security Number (US), passport number, driver’s license number, and any other government-issued identification numbers.

• Financial Information: Bank account numbers, credit/debit card numbers, account balances, transaction history, income details, and credit scores.

• Authentication Data: Passwords, security questions/answers, PINs, and biometric data used for authentication purposes.

The inherent need for financial firms to gather, organize, and exchange everything from email addresses to credit card numbers creates a data economy. Embedding data privacy within this ecosystem requires proactive steps like obtaining user consent before processing data, protecting data from misuse, and enabling users to actively manage their data.

Five fundamental principles of data privacy

Organizations typically use data privacy frameworks to guide their strategy, including the NIST Privacy Framework and the Fair Information Practice Principles. If we distill them and the regulations that underpin them, five common principles appear that are used to inform data privacy policies, processes, and controls within financial services.

1. Access

Data subjects have a right to know what personal data an organization holds on them. They should be able to access their data on demand and update or amend it as required.

2. Transparency

Data subjects have a right to know who holds their personal data and what they do with it. Therefore, organizations should communicate what they are collecting and how they intend to use it. Once collected, organizations should keep them informed about data processing, including any changes to how data is used and any third parties the data is shared with. 

3. Consent

Data subjects should be able to provide organizations with consent for data storage, collection, sharing or processing whenever possible – and withdraw it at any time. If consent is not provided, organizations should have a compelling reason to keep or use the personal data, such as a public interest use or legal obligation. 

4. Quality

To avoid inaccuracies that lead to privacy violations, organizations should ensure the data they collect, and hold is accurate. For example, if a company holds an old address, it could send sensitive documents to the wrong party accidentally. 

5. Security

Organizations should implement processes and controls to protect the confidentiality and integrity of user data – from training employees around compliance and working with third parties with robust privacy controls to implementing technical controls like Identity and access management (IAM) solutions.

What regulations govern data privacy?

The regulatory screw has been tightened across the globe in a bid to protect the privacy of the digital data that underpins industries like financial services. Examples of robust regulations that have been implemented include the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) – both of which came into effect in 2018.

GDPR

The GDPR is designed to give individuals more control over their data and harmonize data protection regulations across Europe. It imposes strict rules on how organizations collect, store, process, and transfer personal data. It also grants individuals various rights regarding their data, such as the right to access, rectification, erasure, and the right to be forgotten. 

GDPR applies to any organization that processes the personal data of individuals residing in the EU, regardless of where the organization is located. Penalties for non-compliance can be as high as €20m or 4% of annual global turnover, whichever is higher.

The UK GDPR is the UK’s post-Brexit version. It’s very similar to the EU GDPR, so organizations that comply with it are likely to comply with the UK version.

CCPA

The CCPA grants California residents various rights regarding their personal information held by businesses, including:

• Right to know: Consumers have the right to request disclosure of what personal information is collected, used, shared, or sold by a business.

• Right to delete: Consumers have the right to request the deletion of their personal information held by a business.

• Right to opt-out: Consumers have the right to opt-out of the sale of their personal information. Businesses must provide a clear and conspicuous link on their website titled “Do Not Sell My Personal Information” to facilitate this opt-out.

• Right to non-discrimination: Businesses are prohibited from discriminating against consumers who exercise their privacy rights under the CCPA, such as denying goods or services or charging different prices.

The CCPA applies to businesses that meet certain criteria, including those that do business in California, collect personal information of California residents, and meet specific revenue or data processing thresholds. How can financial service providers ensure data privacy?

The following steps can help organizations establish a robust data privacy program that meets compliance requirements and protects sensitive information.

Data inventory

They should start by understanding the data compliance regulations that are relevant to them. This generally depends on their industry and geographical location. An inventory should then be developed outlining the types of data the business acquires, handles, and retains, including how it’s obtained, where it’s stored, and who has access to it.

Access controls

Robust access controls – such as user authentication, role-based access, and the encryption of sensitive data – will ensure that only authorized personnel can access PPI. An up-to-date identity and access management program can enhance this.

Data storage

They should implement robust measures that ensure data is stored securely, both physically and digitally. This typically involves deploying encrypted storage solutions, firewalls, and access logs.

Compliance training

By educating staff about data compliance, they can make sure every level of the organization understands the regulations, the significance of data privacy, and their role in achieving it. Regular training sessions can help ensure everyone stays informed about this dynamic requirement. 

Data handling policies

By establishing transparent data handling policies and procedures throughout the organization everyone will understand the correct data management practices – from collection, use, and processing to transfer, disposal, and sharing.

Regular audits

Periodic audits will verify the effectiveness of data compliance measures and help identify potential vulnerabilities and areas that need improving.

Response plan

A well-defined response plan will empower the organization to respond proactively to a data incident. Knowing how to respond effectively and promptly will minimize damage and comply with the requirements of regulatory frameworks.

Data privacy: the future 

As the amount of data, handled by financial service providers, continues to grow exponentially amid consumer demand for online convenience, their responsibility to ensure the privacy of this data is evolving – from complying with new regulations to managing the proliferation of artificial intelligence technologies.

To maintain regulatory compliance, a robust security posture, and competitive advantage, they must adopt a proactive approach to data privacy that keeps pace with its rapid evolution by monitoring change and instilling the agility needed to adapt to it. 

An application has many sections to it. Certain parts of the application will be restricted only to authorized users or to users with special privileges and some will be public. Publicly available parts need not be validated but requests to authorized sections need to be validated.

In this tutorial, we’ll be learning about `middlewares` and how it helps to control access to different parts of the application.

Getting Started with Understanding Protected Routes in Next.js 14

We’ll be using Next.js 14 for this tutorial so please make sure you have Node.js 18 or later. From your terminal prompt type in the following command,

npx create-next-app@latest

As seen in the above command, we are using `create-next-app` to create our Next.js project. The above command prompts you to install the `create-next-app` package. Type in yes,

[email protected]
Ok to proceed? (y)

Once you type in `y` it installs the package. Next, it will ask a couple of questions related to your project. Type in the following responses:

√ What is your project named? ... next-protected
√ Would you like to use TypeScript? ... Yes
√ Would you like to use ESLint? ... No
√ Would you like to use Tailwind CSS? ... No
√ Would you like to use `src/` directory? ... Yes
√ Would you like to use App Router? (recommended) ... Yes
√ Would you like to customize the default import alias (@/*)? ... No

Once done you will have your Next.js 14 project created with some boilerplate code.

Navigate to the project directory and try to run the project,

cd next-protected
npm run dev

Navigate your browser to http://localhost:3000/ and you will have the application running.

Creating an API Route

Let’s start by creating an API route that returns some JSON data as a response. For creating an API route, navigate to your `src/app` folder and create an `api` folder which will contain the code for your API endpoints. Inside `api` create a folder called `photos` and inside `photos` create a file called `route.ts`.

Now this `route.ts` file serves as the root file for the API endpoints of `photos`. Inside the `route.ts` file let’s add a `GET` method which will handle the GET request to the `api/books/` endpoint.

const GET = async () => {
    const data = await fetch('https://jsonplaceholder.typicode.com/photos').then(res => res.json());
    return Response.json({"status":200, "data": data});
}
export {GET}

As seen in the above `GET` method, we are querying another external API using fetch and returning the response as result for `/api/books` GET request.

Save the above changes and restart the application.

npm run dev

Try hitting the endpoint `http://localhost:3000/api/books` either using POSTMAN client or simply in your web browser and it will return an API response.

The above endpoint is public and no matter whoever tries to access the above endpoint will get the request response.

Now let’s try to make the above API route protected.

Creating a Protected API Route

For protecting an API route or request, Next.js 14 provides `Middleware`. A Middleware is something that comes in between your request and before it hits the route.

From the official documentation,

“Middleware allows you to run code before a request is completed. Then, based on the incoming request, you can modify the response by rewriting, redirecting, modifying the request or response headers, or responding directly.”

For creating a middleware go to your `src` folder and create a file called `middleware.ts`. Inside the `middleware.ts` file create a method called `middleware` and export it.

import { NextRequest } from "next/server";

const middleware = (request : NextRequest) => {
    console.log('request is ', request);
}

export default middleware;

Save the above changes and try to hit the API endpoint `http://localhost:3000/api/books`. Once the API returns the response, check the project terminal for the console log from the middleware function.

As seen from the logs, before hitting the endpoint the request passed through the middleware function. So let’s say we are only allowing requests to the endpoint with a particular API key in headers. You can validate it in the middleware and reject invalid requests.

typescript
import { NextRequest, NextResponse } from "next/server";

const middleware = (request : NextRequest) => {
    const {headers} = request;
    if(headers.get('x-api-key') !== "zoomba"){
        return Response.json(null,{status:400, statusText:'Unauthorized request'});
    }
}

export default middleware;

In the above code, we are checking for `headers` from the request. Inside the headers we are checking for `x-api-key` which must be passed with a value `zoomba` for it to be a valid request. In case the request doesn’t have a valid `x-api-key` it will return 400 responses. This way the API route is protected against invalid requests.

Save the above changes and try to make an API request to the endpoint `http://localhost:3000/api/books`. 

If you try to make a GET request from the browser to `http://localhost:3000/api/books` you will get `null` response since the required header `x-api-key` is not being passed.

Next, let’s try to make a GET request to the endpoint with the required header `x-api-key`. 

I’m using a POSTMAN client for testing the API endpoint, you can use the same or any other.

Note: The `x-api-key` being used is a hard-coded one. It’s just for this tutorial. You can use a dynamic encrypted string that can be encrypted on the client side and decrypted on the server side to make sure it’s authentic.

Next up, let’s try adding Middleware logic to Next.js pages.

Adding Middleware to Page

Some pages might not be available to all users. And we can handle page-level restrictions too in the `middleware.ts` file.

Try to navigate to http://localhost:3000/ and the application will return `null`. It’s because we have added a generic restriction to the middleware logic.

if(headers.get('x-api-key') !== "zoomba")

We are checking for `x-api-key` in all requests in our middleware. Let’s modify it a bit to check for only `/api/`.

typescript

const middleware = (request : NextRequest) => {
    const {headers, nextUrl : {pathname}} = request;
    if(pathname.startsWith('/api/') && headers.get('x-api-key') !== "zoomba"){
        return Response.json(null,{status:400, statusText:'Unauthorized request'});
    }
}

By checking if the request pathname starts with `/api/` we can distinguish between API and page requests.

Save the changes and now you will be able to render the application page. 

This way, there is no validation for pages. Let’s add one that checks for a session cookie if the user tries to visit the page.

typescript
const middleware = (request : NextRequest) => {
    const {headers, nextUrl : {pathname}, cookies} = request;
    console.log('cookies ', pathname);
    if(pathname.startsWith('/api/') && headers.get('x-api-key') !== "zoomba"){
        return Response.json(null,{status:400, statusText:'Unauthorized request'});
    }

    if(!cookies.get('session')?.value){
        return Response.json('Access denied',{status:400, statusText:'Access denied!!'});
    }
}

Save the changes and try reloading the application and you’ll get `Access denied`, since the `session` cookie is not found.

Let’s add a cookie to the application. For that go to your application tab in the developer console. From the left side go to storage, cookie, and click on the site URL. There you can add cookies to the application.

Now try refreshing the application and the page will appear since the `session` cookie is present. So this way you can add the middleware logic to control access to pages and API endpoints.

Wrapping it up

In this tutorial, you learned about protected routes in Next.js. You learned how to protect API routes and pages using Middleware. This helps in protecting your application data from unwanted access and data breaches.

This article was originally published on LinkedIn, on July 20th 2024. It’s been updated and reposted here, having incorporated information from the RCA report that was released by CrowdStrike.

The now infamous CrowdStrike incident was accidental rather than an intentional attack. A misconstructed “content” update was distributed, automatically updating thousands of Windows servers and computers with CrowdStrike’s Falcon sensor installed. The situation has since been resolved, as 99% of all servers are back online, but it’s important to reflect on the incident and understand what it means. A lot of the discussion is focusing on the vendor angle, and what they could have done to prevent this. I believe it’s equally important to reflect on what companies could’ve done better.

What caused the CrowdStrike incident?

Falcon hooks into the Microsoft Windows OS as a Windows kernel process, providing it with high privileges to monitor system operations in real-time. However, a logic flaw in Falcon sensor version 7.11 later caused it to crash. This deep integration with the Windows kernel led to a system crash and a Blue Screen of Death (BSOD), affecting the overall stability of the Windows system, and the consequences we witnessed this past July.

What can be done to minimize the risks of these outages?

Anyone in the software development business knows that, regardless of how good your testing and QA processes are, sooner or later you’ll ship a bug to production. It’s a risk that everyone – developers and users alike – accepts as intrinsic to a world where software development is prone to human error. That being said, there’s a lot that the software manufacturer could have done to minimize the risk of this happening. 

Some examples include:

Employ file integrity validations

Create file checksums to detect any corruption potentially introduced between the moment they were created and the moment they are about to be used. Formalize a structure for updating files or ‘content’  that can be validated before usage. It is now known that “the sensor expected 20 input fields, while the update provided 21 input fields”. Detecting this mismatch before applying the patch would’ve saved the day. Another approach could focus on code signing of updates during testing. Anything after that tampers or corrupts the update, would not have the key to generate a valid signature. The sensor must validate this signature, otherwise, the update should be rejected;

Proper testing before shipping

Installing the update on test machines before shipping. CrowdStrike might have done this, but the update might have been corrupted after testing and before being installed. Their RCA report doesn’t mention the corrupted update file, so we have to assume that it was a misconstructed content update, and a failure to validate the update before applying it. CrowdStrike’s official RCA does not clarify exactly what their testing procedures are. 

Staged rollout updates

Before issuing an update to all the customers, roll them a tiny fraction to confirm that they landed well. This can limit the impact of any problem;

Reboot loop protection

A simple technique implemented by kernel-level drivers that when they boot, it first detects if they crashed and, if so, avoids running fully again to prevent reboot loops;

Move the agent into user space

The BSOD problem is caused by a crash in kernel-space code. Moving this to user space would solve the BSOD problem, as the program would just crash without taking the whole system with it;

Move to a memory-safe language

Rust would be most people’s top preference here.

Is it fair to say that companies that use CrowdStrike could’ve done better?

It’s difficult to say what the right answer is. Let’s think about it carefully. When a company decides to install software like CrowdStrike on their servers, it means that they trust this company not to do anything malicious. After all, it’s a $86B valued company. Why would it jeopardize their reputation? 

I bet you are already spotting the fallacy here. The biggest problem isn’t the vendor’s desires or motivations, but rather unintentional failures, such as failure to properly manage the integrity of updates or to validate them – or being compromised by a threat actor. These issues, combined with the trust that companies are putting on vendors, can lead to significant damages.

Should we trust the vendors that we use blindly? Auto-updates, especially those related to security, are definitely a trend. Is this the right approach? I believe it is. Auto-updates offer more benefits than risks, and the problem is not that they can fail us. The problem is that we don’t always consider updates to the software we depend on as part of our productive system. If we do, then we must ensure updates don’t break our services. That is also valid for security testing. We should run static analysis, dynamic analysis, and other types of security checks even if the only change is a patch to a third-party dependency.

We can never be sure that we’ll be able to catch every issue before shipping. Therefore, we need to assume components that we use might cause dependent services to become unavailable. IT managers know how to plan for business continuity, often by having secondary systems in place for situations like this. But they know better not to have exact copies of the system. At the end of the day, this is also a business decision, because the cost versus the risk of a catastrophic failure could result in the company just accepting the risk and the impact if it happens.

The scale of this incident made me think about what this means for cyber resilience.

In light of the world’s current economic struggles, is there a trend towards “monoculturization” in cyber defense? If there is, that could mean that companies are increasingly relying on a single vendor (or fewer vendors) to defend their assets. It doesn’t help that we have been seeing a lot of consolidation in the cybersecurity sector, with increased M&A activity in response to the economic downturn.

Lack of diversity doesn’t cause the problems, but it makes the consequences harsher when they happen. It arguably attracts more threat actors, as they prefer focusing on more ubiquitous systems that offer them more bang for the buck.

So here we are blaming the vendor when we have so many things in our control that would have helped:

1. Introduce redundancy (with diversity) to be more resilient to failures and impose a much higher cost to attackers, who then have to defeat multiple systems to succeed.
   
   

2. Treat the supply chain as part of our application – if we are applying a patch on a component our production system depends on, then we should test it as thoroughly as we test any other app we develop and deploy – we should patch a staging environment first. If the service passes the tests, then we apply the patch to the production environment
   
   

3. A “content update” is still a production update – some people pointed out that it wasn’t a driver update but just a ‘content update.’ However, there’s a possibility that a content update, or any type of update, could trigger the existing driver in an unexpected way, potentially causing a catastrophic failure. Therefore, any update should be treated as a production change that requires thorough testing (including security testing).
   
   

4. Isolate components that we use so that in the event of failure, they don’t compromise the whole system. In the case of CrowdStrike, this is easier said than done, as it is deployed to monitor every system. However, the principle still stands for other components that might fail.
   
   

5. Avoid “monoculturization” inside our organization. Ensure that in our threat model, we consider every dependency our production systems have, which can be compromised or become unavailable. How should we address it?

As lawsuits start to unfold, and while we should demand accountability from CrowdStrike, this incident should also serve as a warning that we shouldn’t see our supply chain third-party components as another company’s problem. We should plan for failure in these components the same way we plan for failure in the components we develop. It’s not about dismissing CrowdStrike’s responsibility. It’s about admitting that there are things that we can control and focusing on that.

So, it’s not them, it’s us.

As the deadline for PCI DSS v4 compliance is approaching, companies that rely on online payment pages to bring in revenue start to feel the pressure of finding a solution quickly and fulfilling compliance requirements 6.4.3 and 11.6.1 without expending internal resources. 

With simplicity and efficiency in mind, Jscrambler developed a PCI DSS Quick Program aimed at removing obstacles to PCI DSS compliance for Merchants and removing the stress of finding an appropriate solution that is reliable and cost-effective. The changes in version 4.0.1 of the Standard only confirmed the necessity of keeping a close eye on the vendor inventory and having an alert mechanism in place for monitoring changes. 

5 Areas of Focus to Accelerate Efficient Compliance

The PCI DSS Quick Start Program consists of the following areas that ensure fast onboarding and continuous compliance. 

Payment Page Inventory Report (Prepare)

One of the core parts of the new requirements is keeping a vendor inventory: “An inventory of all scripts is maintained with written business or technical justification as to why each is necessary.” To help merchants prepare and gain visibility of vendors present on their payment pages, Jscrambler offers a free Payment Page Analysis Report. It is a one-time upfront analysis of your payment page inventorying every script present, while also detailing which scripts are accessing sensitive data and exfiltrating data to external IP addresses, domains, and vendor sites. 

Every report is delivered within 48 hours of the request to help prepare for ongoing compliance. 

This is designed as the first step as there is no commitment and no contract is required. Anyone can benefit from this Jscrambler tool. 

This is an example report that gives an overview of vendors present on the payment page with more details in the Diagnosis section.

Unified Hybrid Architecture (Deploy)

After clarifying which vendors are present on your website, Jscrambler facilitates a fast onboarding process and analysis of your payment pages by giving you the flexibility to start with an agentless deployment, accelerating time-to-value and compliance. Jscrambler’s WPI PCI DSS Hybrid Architecture enables organizations of any size or complexity to utilize both Agentless Monitoring and Agent-Based Protection for enhanced security and compliance.

All you need to start with Agentless is to provide your payment page URLs and recurring payment page analysis is ready to be activated without any configuration to your website. 

This is a perfect solution for companies that don’t have the luxury of a long vendor evaluation process and who are selecting a comprehensive client-side protection and compliance solution before satisfying the basic PCI DSS v4 compliance requirements. It is also something that doesn’t require any manual effort from your team.

Automated Payment Page Compliance (Comply) 

Here’s how the automated recurring payment page monitoring will work to fulfill the compliance requirements. The payment page analysis will be executed either 24/7 or every seven days to meet the recurrence requirements outlined by PCI DSS. The analysis results include the inventory, authorization, detection, monitoring, and alerting needed to meet PCI DSS requirements 6.4.3 and 11.6.1. 

Requirement 6.4.3 Based on Behavior

PCI DSS v4 Requirement 6.4.3 is designed to minimize the attack surface and manage all payment page scripts that are loaded and executed in the consumer’s browser.

Benefits of the Quick Start Program

Streamlined Management

The Jcsrambler product is designed to streamline script authorization management. There are fewer approvals due to Vendor Service grouping. Moreover, you only approve behaviors, not individual scripts, because it’s very common for scripts to change and for vendor service to rely on tens or hundreds of different pieces of JavaScript. So you’re doing all those in one pass.

Flexibility with Hybrid Architecture

With the Jscrambler Hybrid Architecture, you have a lot of flexibility available. For example, if you acquire another company, or another brand, and you need to quickly bring their payment pages into compliance, you can use Agentless Monitoring to have them being monitored and under compliance close to the same day. All can be done within a few hours without having to go through change management because you’re not affecting the website itself.

Once you identify the sections of the business that might be more or less dangerous, and might have more or less risk, that’s where you might look to include the Agent so that you can have direct control over those particular pages or experiences.

Proactive Control & Data Leakage Prevention

Proactive control and prevention allow you to set up rules ahead of time and identify those third-party vendors that should always have access to cardholder data while blocking everyone else. For example, if Strike is your payment processor or PayPal, you allow these vendors to handle cardholder data. Other vendor services will not have access to cardholder data on payment pages. The Jcrambler solution will take care of all that automatically on the client side.

Simplified Workflows with Delegated Compliance

You can use Jscrambler to delegate certain compliance tasks over if your organization is either small or just doesn’t have a lot of experience with JavaScript or wants another helping hand. You can give a lot of the approval tasks over to the Jscrambler team where we can go in and actually do certain approvals for you.

PCI DSS Expertise

The Webpage Integrity (WPI) product has been in the market for 5 years. The anti-skimming capabilities of WPI were developed long before the PCI DSS v4.The Jscrambler WPI PCI module is designed with input from the industry and QSA partners. It has a purpose-built user interface and it’s easy to use the solution and manage your workflows.

Key Takeaways

Protecting your payment page in accordance with PCI DSS v4 is crucial to safeguard sensitive customer information and reduce the risk of data breaches, and complying now ensures that your business remains secure and avoids potential fines and reputational damage. Jscrambler has developed a Quick Start Program to help you:

In this tutorial, you’ll learn how to build APIs using Next.js 14. The newer version of Next.js provides the platform to create APIs using the App router. 

Let’s start by creating our Next.js 14 project. As a prerequisite, you’ll be required to have Node.js 18.17 or later to work with Next.js 14. You can check the Node.js version currently installed in your system. For that open your command prompt and type in the following command,

node --version

which will output something like,

v20.10.0

If you already have the required version installed you are good to go. Otherwise, you can install the latest Node.js version.

Once you have the required Node.js installed, you can start by creating a new Next.js project using `create-next-app`.

npx create-next-app@latest

The above command will prompt for a couple of questions related to the project creation,

√ What is your project named? ... next-14-api
√ Would you like to use TypeScript? ...Yes
√ Would you like to use ESLint? ... No
√ Would you like to use Tailwind CSS? ... No
√ Would you like to use `src/` directory? ...Yes
√ Would you like to use App Router? (recommended) ... Yes
√ Would you like to customize the default import alias (@/*)? ... No

Fill in the response as shown above and once done you will have the boilerplate Next.js project ready to run.

Navigate to the project directory and run the project.

cd next-14-api

npm run dev

Point your browser to http://localhost:3000 and you will have the default project running.

Building API Using Next.js: Project Structure

You have the ‘ src ‘ folder inside the project folder, `next-14-api`. All the project source code resides inside the `src` folder. Inside the `src` folder create a folder called `api` which will serve as the main folder for our Next.js APIs.

Once you have the `api` folder, create a folder called `users`, and inside `users` create a file called `route.ts`. Every API endpoint will have a file called `route.ts`. 

Here in our case, since there is `route.ts` inside the `api/users/` folder, the API endpoint will be `/api/users`.

GET API Endpoint

To begin with, let’s create an API endpoint inside the `route.ts` file. Start by defining a function for a GET request as shown.

typescript
const GET = () => {
    return Response.json({"status":200, "message":"SUCCESS"})
}
export {GET}

As seen in the above method, we are returning a JSON response for the API endpoint’s GET request.   To test the GET request API endpoint, you can restart the application. Once the application is up and running try accessing the endpoint using http://localhost:3000/api/users and you will be able to see the response.

{"status":200,"message":"SUCCESS"}

In addition to what we defined in the above GET method, let’s make it a bit more realistic by adding an API call inside the GET method. For that, you need to mark the method as `async` since we’ll be using `await` to fetch the data from API.

typescript

const GET = async () => {
    const response = await fetch('https://jsonplaceholder.typicode.com/users');
    const responseData = await response.json();
    return Response.json({"status":200, "data": responseData})
}

export {GET}

In the above code, we are making an API request to an external API endpoint and then returning the received data as the response from our `/api/users` endpoint.

Save the above changes and try making a GET request to http://localhost:3000/api/users and you’ll be able to see a JSON response with data from the external API endpoint.

Now, let’s have a look at how you can read the query parameters from the API endpoint. Here is how you can pass a query parameter to the endpoint:http://localhost:3000/api/users?id=1. To read the query parameter passed to the endpoint, add a `request` parameter to the GET method.

const GET = async (request:any) => {
    const response = await fetch('https://jsonplaceholder.typicode.com/users');
    const responseData = await response.json();
    return Response.json({"status":200, "data": responseData})
}

Next let’s create a URL using the `url` from `request`.

typescript
const { searchParams } =  new  URL(request.url);

Once you have the `searchParams` you can get the expected query string parameter being passed.

typescript
const  userId  =  searchParams.get('id');

Now let’s try passing the `userId` along with the API endpoint URL to filter the API response as per the `id`.

Here is the modified GET method,

typescript
const GET = async (request:any) => {
    const { searchParams } = new URL(request.url);
    const userId = searchParams.get('id');
    const response = await fetch(`https://jsonplaceholder.typicode.com/users?id=${userId}`);
    const responseData = await response.json();
    return Response.json({"status":200, "data": responseData})
}

Save the above changes and try to do a GET request by passing a query string as http://localhost:3000/api/users?id=1 and you will get the id-specific response.

Moving on, let’s have a look at how to create a POST API endpoint.

POST API Endpoint

To create a POST API endpoint, you need to create another method called POST and export the method.

typescript
const POST = () => {
    return Response.json({"status":200, "data": "Data updated successfully"});
}
export {POST}

Save the above changes and once you make a POST request to http://localhost:3000/api/users you’ll get the following response,

json
{
    "status": 200,
    "data": "Data updated successfully"
}

While posting data to an endpoint you might be sending in some data to the API endpoint. Further, let’s see how to read data posted to the POST API endpoint.

Inside the POST method, you can define a parameter called `request`. We’ll be using the `request` parameter to read the data posted to the endpoint.

Doing `request.json()` would return the parameters passed in the body of the request. Let’s use it to read the request body and return the data in response.

typescript
const POST = async (request: any) => {
    const params = await request.json();
    const name = params['name'];
    return Response.json({"status":200, "data": "Data updated successfully", "name": name});
}

Save the above changes and try sending a POST request with `name` in the request body. The value of the `name` parameter will be returned in the response.

json
{
    "status": 200,
    "data": "Data updated successfully",
    "name": "Roy"
}

Next, let’s see how you can create an API endpoint for DELETE requests.

DELETE API Endpoint

Create a function called DELETE in the `app/api/users/route.ts` file and also export the function.

typescript
const DELETE = async (request:any) => {
    return Response.json({status : 200, message : "Data deleted successfully"});
}

export {GET, POST, DELETE}

Now if you try to make a DELETE request to the API endpoint http://localhost:3000/api/users you will be able to get the following response,

{
    "status": 200,
    "message": "Data deleted successfully"
}

Passing data to the DELETE endpoint will be required. It can be either as a query string that we saw in the GET method or in the request body as we saw in the POST method.

Let’s try passing in the body as we tried in the POST request. Here is how the modified DELETE method looks:

typescript
const DELETE = async (request:any) => {
    const params = await request.json();
    return Response.json({status : 200, message : "Data deleted successfully", params});
}

Now if you save the above code and hit the API endpoint with a DELETE request with some data in the request body, that data would be returned in the response.

So, when I hit the endpoint with the following JSON data,

json
{
    "name": "Roy"
}

The response from the API is as shown,

json
{
    "status": 200,
    "message": "Data deleted successfully",
    "params": {
        "name": "Roy"
    }
}

Similar to how we created API endpoints for GET, POST, and DELETE requests, endpoints for PUT, and PATCH requests can also be created.

Wrapping it up

In this tutorial, you learned how to create API endpoints in Next.js 14 using App routers.

You learned how to create an API that accepts GET, POST, and DELETE requests. You can further extend it to create requests for PATCH and PUT requests.

In cybersecurity, the strategic control of network access plays a pivotal role in safeguarding digital assets. Allowlisting vs. blocklisting emerge as two fundamental approaches in this endeavor, each offering distinct benefits and challenges. Allowlisting involves granting access only to pre-approved entities, promoting a proactive defense against potential threats. On the other hand, blocklisting aims to thwart known malicious entities swiftly, offering simplicity and quick response capabilities.

This exploration delves into the intricacies of allowlisting and blocklisting, dissecting their advantages and limitations.

As organizations grapple with the relentless surge of cyber threats, understanding the nuanced dynamics between these two methods becomes essential for establishing robust and adaptive security measures.

Importance of Allowlisting and Blocklisting in Cybersecurity

In the constant battle against cyber threats, allowlisting and blocklisting stand as essential tools in any cybersecurity arsenal. While seemingly opposites, they work together to create a layered defense, offering complementary benefits that significantly enhance overall security.

Allowlisting:

• Reduced Attack Surface: By explicitly defining and approving only authorized entities, you shrink the potential entry points for threats, minimizing the damage they can inflict. This “trust-but-verify” approach offers proactive protection in a world teeming with unknown malware.
  
  

• Simplified Management: Maintaining a whitelist of known good entities is often easier than keeping track of ever-evolving bad actors. This efficiency translates to faster response times and a reduced administrative burden.
  
  

• Compliance Adherence: Many regulations require specific restrictions on data access or software usage. Allowlisting ensures automatic compliance, simplifies regulatory adherence, and reduces risk.

Blocklisting:

• Proactive Threat Prevention: By actively blocking known malicious actors, spam, and harmful content, you prevent them from reaching your systems in the first place. This proactive approach stops threats before they can even attempt infiltration.
  
  

• Reduced Damage Potential: Even the most robust defenses can be breached. Blocklists act as a secondary line of defense, mitigating the damage caused by successful attacks by restricting the attacker’s movement within your network.
  
  

• Improved Productivity and Control: Blocking unproductive websites and applications can enhance user focus and productivity. Additionally, content moderation becomes easier through targeted blocking, creating a safer and more controlled online environment.

Allowlisting

Allowlisting, also known as whitelisting, employs the core concept of “zero trust” to block access by default, allowing only expressly approved sources to access an asset. Whitelisting can be used on any asset (network, endpoint, application, etc.) to grant particular access to any sort of source.

Consider your company’s network to be a tightly secured entrance, with your admin serving as the diligent security guard in the front. Allowlisting works in the same way that security guards confirm employees with approved IDs. It maintains an exclusive list of accepted applicants, allowing only well-vetted personnel to enter. 

Allowlisting Use Cases

Allowlisting should be utilized when access can be clearly defined, such as for internal resources. Examples of effective allowlisting use cases are:

• Email security program, allowlisting email addresses ensures proper email delivery from trusted senders.

• IP address allowlisting in a firewall for branch offices

• Web address allowlisting on a server to restrict the potential external connections for a susceptible asset.

• Device Allowlisting MAC addresses and programs for network access and internal database access.

• User allowlisting for an internal company application.

Benefits and Challenges of Allowlisting

Though blocklisting was formerly popular, the recent exponential surge in malware implies that it is no longer effective.

Allowlisting only enables a few programs to operate, effectively reducing the attack surface. Furthermore, creating an allowlist is much easier because the number of trusted programs is significantly lower than the number of distrusted ones. Allowlisting can help businesses adhere to tight regulatory compliance requirements.

Allowlisting has some drawbacks, despite its many advantages. Building an allowlist may appear simple, but one mistake might result in a backlog of help desk inquiries for the administrator. The inability to access important apps would hinder a variety of critical tasks. Furthermore, deciding which programs should be allowed to run is a time-consuming task.

As a result, administrators often implement extremely wide allowlisting policies. This mistaken faith might jeopardize the entire company. Another downside is that, whereas blocklisting can be partially automated with antivirus software, allowlisting requires human participation to function properly.

Blocklisting

Blocklisting, also known as Blacklisting, is a security mechanism that prevents known dangerous people, IP addresses, websites, devices, or programs from accessing an organization’s resources.

Many security systems have a blocklist as part of their anti-malware or attack-blocking features, which organizations can manually add to. Blocklisting does not adhere to the principles of zero trust because the default condition for access is to typically allow access until blocklisted.

Blocklisting is one of the oldest computer security techniques, and most antivirus software uses it to block harmful organizations.

The process of blocklisting applications is compiling a list of all the applications or executables that could constitute a hazard to the network, either through malware assaults or simply by interfering with productivity. Blocklisting might be viewed as a threat-centric technique.

Blocklisting Use Cases

When potential access sources are difficult to establish, such as with public resources, blacklisting is frequently the preferred option. Examples of effective blacklisting use cases are:

• Email security software, email addresses that are known to convey spam or viruses are blacklisted.

• In a firewall, IP addresses are blacklisted as the source of harmful assaults.

• DNS server blacklists pornography websites and MAC addresses of known botnets.

• Application blacklisting, like malware signatures in an antivirus program

• User blacklisting of users who violated community rules in a discussion forum.

Benefits and Challenges of Blocklisting

The obvious advantage of blocklisting is its simplicity. Administrators can quickly disable known malicious applications while running everything else. This ensures that users have access to all of the applications they require, lowering the number of admin tickets raised or vital applications disabled. Blocklisting is an effective strategy for businesses looking to take a more liberal approach to application restrictions.

However, merely blocking anything that is distrusted, while simple and efficient, may not always be the best strategy. Every day, over 200,000 samples of malware are developed, making it hard for an administrator to maintain a complete and up-to-date list of harmful apps. And, given that 30 percent of malware targets zero-day vulnerabilities, a security breach could occur before the vulnerable programs are added to the blocklist.

Unfortunately, in the event of a zero-day attack, organizations will be left susceptible, regardless of their security strategy. The increasing increase in targeted attacks aimed at obtaining confidential data from organizations should likewise concern administrators. Predicting and stopping these types of assaults by blocklisting would be useless.

Application Allowlisting or Blocklisting

Application Allowlisting or Blocklisting is sometimes mistaken with Allowlisting and Blocklisting. Although application allowlisting and blocklisting are components of allowlisting and blocking, they function under more flexible rules.

Application Allowlisting

Application allowlisting is similar to an elite club membership, guaranteeing that only the most trustworthy IP addresses, domains, and apps are given the red-carpet treatment. It is the process of compiling a list of approved entities, such as domains and applications, that are permitted to access a specific resource or take a specific activity.

The United States National Institute of Standards and Technology (NIST) has released a Guide to Application Whitelisting, which proposes utilizing two of the following attributes together to define an application for whitelisting.

• File Path permits all apps to execute within a given file path or directory, however it is a broad property that cannot prevent malicious software from operating in the correct location.

• File Name permits a certain naming convention to be used but does not check for renamed dangerous files or malware-infected files.

• File Size merely checks the file size and can easily allow malware with the right file size to execute.

• A digital signature can provide a unique value to an application, but it may become obsolete when fixes and upgrades are performed.

• Cryptographic Hash provides the most unique and least spoofable value for whitelisting, but it will be invalidated if the software is patched or updated.

Application Blocklisting

Application blocklisting: the ultimate antivirus or firewall. It’s like having your squad of security guards, ready to face known aggressors. Consider a list of malicious IP addresses that are blocked from your network, guaranteeing that they never gain access. What about those spam email addresses? Blocklisting also helps to keep your inbox clean. 

Alternative Names

Allowlisting and Blacklisting as stated earlier can also be called Whitelisting and Blacklisting, While these are common terms, there’s a growing movement to use more neutral alternatives. This shift reflects concerns that the color-based terms can be insensitive and perpetuate harmful associations.

Several platforms have already adopted new terminology. To ensure you understand the latest options within your security tools, here are some updated terms:

Allowlisting:

• Whitelisting(Superseded)

• Allow-listing

• Permitted listing

• Approved listing

Blocklisting:

• Blacklisting(Superseded)

• Denylist

• Deny-list

• Blocked list

• Disapproved list

Conclusion

Both allowlisting and blocklisting offer valuable tools for managing access and security, each with distinct benefits and challenges.

Choosing the right approach depends on your specific needs and priorities. For maximum protection, consider a hybrid strategy that combines the strengths of both. Allowlisting provides a foundation of trust, while blocklisting offers a safety net against unforeseen threats.

Remember, security is an ongoing process, and regularly updating and adapting your approach is crucial to navigating the ever-evolving digital landscape. By understanding the advantages and limitations of each method, you can craft a defense that keeps your system secure, productive, and compliant.
