Ensuring API security within the DevSecOps framework

Introduction DevSecOps framework

In the rapidly evolving digital era we are in today, Application Programming Interfaces (APIs) have emerged as the silent heroes. They act as connectors for almost all of our favorite apps, and because they ensure that different software components are connected seamlessly, we can enjoy their many benefits. With the proliferation of APIs in nearly every application that we use, it’s no surprise that their security has become a pressing concern. Looking deeper, it becomes evident that the symbiotic relationship between API security and DevSecOps is a crucial merging of disciplines. Both fields are becoming increasingly intertwined, marking a significant shift in how we approach software development and security. This article aims to shed some light on this convergence, emphasizing the urgency of strong API security in the current digital landscape.

Understanding DevSecOps

DevOps, as a methodology, emerged with the vision of bridging the divide between software development (Dev) and IT operations (Ops), promising more agile deliveries and a smoother development lifecycle. Yet, as cyber threats continued to grow, an important element was found missing from the formula: security. Enter DevSecOps. By integrating security considerations directly into the DevOps workflow, DevSecOps mandates that security isn’t a bolted-on afterthought but rather an ingrained part of the development process from inception. By doing so, it shifts the security paradigm from reactive patching of vulnerabilities to a proactive model, addressing potential threats even before they manifest. As we navigate deeper into the era of the web, the tenets of DevSecOps are becoming not just preferable, but indispensable.

APIs – The Gateway to Your Application

At the heart of almost any of our favorite applications lies a network of APIs, often working behind the scenes to power the functionalities we have come to depend on. Think of APIs as the unseen conductor of an orchestra, coordinating various instruments (services and platforms) to produce a harmonious user experience. However, as these facilitate data flow and interconnectivity, they also become potential points of entry for malicious actors. A breached API can give attackers undue access, potentially compromising sensitive data or even hijacking entire systems. Given their central role, leaving APIs unguarded is akin to leaving your home’s front door wide open. Recognizing the role of APIs in modern applications means also understanding the immense responsibility of securing them against threats.

Best Practices for Ensuring API Security within DevSecOps

Protecting your digital assets is more than just an obligation, it is a commitment to your users and stakeholders. In the realm of API security, DevSecOps present a comprehensive blueprint. Here is the breakdown of some pivotal strategies:

Authentication and Authorization

It is not enough to know someone is at the door; we must be sure of their identity and intentions. Implement robust mechanisms like OAuth and JWT to ensure only legitimate users access your APIs, and that those users are only doing what they are supposed to be able to do. Below is an example of a commonly used method of authentication: OAuth.

Rate Limiting and Throttling

It is not just about the quantity of requests, but the quality. By controlling the frequency of API calls, you shield yourself from potential DDoS attacks and maintain service integrity as well as availability. Having an API that is not usable by your actual users, is like not having an API at all.

Input Validation

Like a vigilant gatekeeper, this process ensures that only valid and safe data enters the system. Proper input validation safeguards against injection attacks and other malicious activities. Thankfully, there are some great resources to help you with input validation for your APIs. One resource that provides incredible expertise on this is the OWASP Input Validation Cheat Sheet.

Regular and Automated Security Testing

Vigilance is the name of the game. Continuous and automated security tests highlight vulnerabilities before they can be exploited, acting as a crucial preventative measure. Regular automated testing also makes sure that you have proper test coverage on your whole API codebase. Akto can help you out in this area.

Logging and Monitoring API Calls

The more knowledge you have about your APIs the better. Knowledge is power. By tracking API interactions, anomalies are quickly detected, paving the way for timely interventions. Most cloud providers will have some of this logging and monitoring capabilities built into their API products. Google Cloud, for instance, has a multitude of dashboards that will allow you to monitor the behavior and health of your APIs like the one below.

Encryption In-transit and At-rest

Data is a modern-day treasure, and like any treasure, it needs protecting. Encrypting data both as it travels and when it is stored is non-negotiable for airtight API security. Hashicorp does this well. You can see in the diagram below, it is a very good example for keeping data encrypted as much as possible both in-transit and at-rest.

API Gateway Implementation

Think of this as the fortress wall, governing and managing incoming requests to ensure both optimum performance and enhanced security. This is also a service that a lot of cloud providers have built into some of their services. This time we can use an example from Azure. You can see a diagram here to set up a gateway to protect APIs, and you can see the documentation of this entire process here.

Real API Case Studies

One way to really see the impact that sidelining API security could have on an enterprise, is to look at some of the companies that have unfortunately come under attack due to API issues. Here are some examples to show you how seemingly small issues can cause massive problems.

Optus data breach via API endpoint

With this API breach, attackers discovered a publicly exposed endpoint that did not require authentication. This endpoint exposed very sensitive information about Optus customers. On top of this, it was discovered that the API developers used sequential IDs. This made users easy to enumerate for attackers. This breach had a huge financial impact on the company. It was speculated to be over $100 million in financial impact.

Twitter has ~5 million user’s data leaked online

Twitter also had one of the biggest API breaches in the past few years. Attackers found a vulnerability in the Twitter API that allowed them to submit email addresses or phone numbers, and retrieve the user's associated twitter account. Thankfully this breach only disclosed information like birthdays, addresses, phone numbers, and email addresses. But with all this leaked data, other attackers could definitely have used it for more creative attack paths.

3Commas has API keys stolen

Sadly, some breaches do cause massive financial damages to users. In December of 2022, an attacker put out a pastebin showing they had breached a 3Commas database, and from this database they were able to retrieve API keys that are used to perform transactions on a multitude of platforms. With the API data, attackers then linked their own blockchain wallets to these accounts and made trades on a user’s behalf. This attack caused an estimated $20 million loss from these exchange accounts into the attacker's wallets. Halborn has a more in-depth analysis.

Challenges in Ensuring API Security in DevSecOps

The path to integrating API security within a DevSecOps framework is not without its struggles and hurdles. As teams reach for as close to perfection as possible, they encounter challenges unique to the nexus of APIs and security. Let’s unpack some of these complexities:

1. Technical Intricacies of Continuous Monitoring: APIs are dynamic, often changing in tandem with application requirements. Keeping an eye on these constantly shifting interfaces, while necessary, can pose technical challenges, especially when dealing with legacy systems or complicated architectures.

2. Addressing False Positives During Automated Testing: Automation, while efficient, is not infallible. Automated security scans can sometimes raise false alarms, leading teams down rabbit holes or causing unneeded panic. Distinguishing genuine vulnerabilities from false positives is something that will take time while you configure and set up your tooling in the best way possible.

3. The Evolving Nature of API-based Threats: Threat actors are resourceful, always innovating their attack vectors. The threats faced today might be entirely different from those we encounter tomorrow. Staying a step ahead requires not just good technology, but also a mindset of continuous adaptation.

4. Balancing Speed with Security: DevSecOps aims to integrate security without hampering the agility that DevSecOps promises. Finding the equilibrium where security measures don’t slow down development and deployments can be a very hard balance to find.
