Rapid uptake in adoption by industries ranging from banking to retail to autonomous vehicles of customer- and partner-facing and internal application programming interfaces (APIs) to drive internet traffic has resulted in an equally rapid growth in endpoint attacks – more than 11 billion over just 18 months according to a report from edge computing security leader Akamai. It makes sense that they are more vulnerable to threats from malicious actors, given API endpoints’ similarity to internet-facing web servers, and their role as pipelines between divergent platforms.

For DevSecOps teams, protecting APIs is a top priority; they are vital to mobile, SaaS, and web applications and paramount to a healthy software development lifecycle. API security is also a natural extension of DevSecOps’ push to break down silos between development, security, and operations and move toward automation and design that integrates security as a shared responsibility. 

Thus, it is time to view API security not as an external bottleneck, but as a part of a stable long-term strategy. This can be achieved by altering company attitudes and investing in API tools that facilitate testing, enforce governance standards, and automate recurring security tasks.

Adopt an API-as-a-Product Strategy

A primary reason digital transformation efforts have failed for many brands is because they do not see APIs adding value. As such, they’ve lost track of the potential return on investment (ROI) APIs can deliver. When APIs are not viewed as assets or value-generating, they aren’t subject to the appropriate level of protection or security performance oversight. In fact, Akamai’s report highlighted the fact that many enterprises relegate API security checks to the end of the lifecycle and rely on traditional network security solutions which aren’t designed to protect against the attacks to which APIs are subject.

This is starting to change, however, as API-as-a-Product strategies gain traction within the developer community. There is a notable shift away from delivering project features based on budgets and deadlines to holistically examining APIs as products and assessing their capabilities. Further, as the concept of monetizing APIs gains prominence, their protection becomes a higher priority at the outset, with organizations more inclined to adopt a human-centered design approach. 

What this means is moving API regression tests to the forefront rather than treating them as an afterthought. It means adopting a design-first approach – wherein everyone on the team speaks the same language and every tool is able to leverage the same design – from the outset with the help of an API management platform. This will also help ensure that APIs are built on established authentication and authorization mechanisms such OAuth 2.0, which is the industry-standard protocol for authorization, and OpenID Connect.

API testing tools are critical for protecting something upon which most services in use daily rely. These tools let developers see if an API is reacting adequately to unexpected inputs or possible security attacks. They show immediately if an application is running with optimized functionality, reliability, and security.

Whether it is running user authentication, parameter tampering, unhandled HTTP, or fuzz testing, it is imperative to test an API contract to ensure that services can communicate and that the data they share is consistent with a specified set of rules or standards. Further, there are many solutions in the API testing market, including cross-cloud API testing software, software that supports asynchronous testing and continuous integration/continuous deployment (CI/CD) integrations, and end-to-end testing – as well as solutions that support various formats eliminating the need for developers to learn new languages. 

Continuous testing is essential across the DevSecOps pipeline, as is robust test coverage based on API contracts that have been designed and approved. Plus, by chaining together complex API transactions and workflows, cases can be tested on-demand using continuous delivery or CI/CD to reduce downtime. 

Security in 360-degree Lifecycle Management

While API security considerations have typically been an afterthought to ever-increasing business demands, the reality is that no enterprise can afford for software security checks to be the last stage of an API lifecycle. Rather, security must be part of a 360-degree API lifecycle management strategy. It should be incorporated into every level, from planning and design to developing, testing, and release management – all the way out to deprecation.

Developers must also have oversight throughout the entire API lifecycle – which is where an API management platform comes into play. A dedicated platform can provide workflow visualizers that show an API’s complete lifecycle in a single view with issue alerts, which helps accelerate production using CI/CD in the DevSecOps pipeline to build trusted artifacts and more rapid iterations, thereby guaranteeing a security-first mindset. 

API tools also allow perimeter scans, which enable the discovery and inventory of APIs and allow for easy breakdowns for DevSecOps teams to work with. The best platforms will leverage a command line interface (CLI) – a unified tool for managing and controlling multiple services from the command line or with automation through scripts – to make APIs more easily discoverable. The team can easily determine where and how many APIs are deployed; a level of visibility that is mandatory for enterprises. 

Tools for Success

In short, an API team is only as successful as the set of tools at its disposal.

API security best practices are no mystery to seasoned security professionals – and they start with establishing solid API security policies through an API management platform. 

Finally, a collaborative approach to API governance – in line with the DevSecOps mission to eliminate siloes – is imperative for any organization’s security.
