What is API Security Testing? API security testing is a process of carefully evaluating API endpoints to identify and remediate vulnerabilities such as fuzzy input, parameter tampering, or injection attacks. Acting as the first line of defense, it meticulously examines endpoints to identify and neutralize vulnerabilities before attackers can exploit them.

APIs are essential for modern applications as they enable seamless communication and data exchange, serving as the foundation of these applications. However, their interconnected nature makes them vulnerable to various threats. The high volume of API calls - ranging from millions to billions every month - poses a challenge in distinguishing between genuine attacks and harmless irregularities.

Application Programming Interfaces (APIs) are the connecting tissue that enables the communication between applications, internal and external, and facilitate data exchange on a massive scale. In a world where information is the crown jewel of an organization, APIs are driving the delivery of digital services to customers and partners. While their usage is already exploding, the growing popularity of cloud-native technologies and microservices has only accelerated API adoption.

APIs were already ubiquitous in driving modern applications. However, the pandemic has further accelerated growth in innovation and expansion of digital services, making APIs even more widespread. In today’s world, rapid innovation would not be possible without secure APIs. Attacks on APIs are increasing exponentially. Gartner suggests API abuses are the most significant attack vector since 2022. Hence securing APIs is more critical than ever in the past.

In the age of digital-first businesses, every other software solution either uses an API (Application Programming Interface) or makes one. They enable various applications and services to work together, enabling businesses to improve features, streamline user experience, and provide new exciting offerings. Unfortunately, the more APIs we collect and interact with, the more security challenges increase.

APIs are increasingly becoming the target of choice for attackers. According to the key findings stated in the 2024 Gartner Market Guide for API Protection, "APIs — especially shadow and dormant ones — are causing data breaches among organizations that, on average, exceed the magnitude of other breaches.

A significant vulnerability (CVE-2024-41110) was recently discovered in Docker Engine version 18.09.1.Although the issue was identified and fixed in 2019, the patch did not apply to other major versions, resulting in regression. The vulnerability was assigned a CVSS score of 10 (critical).

Businesses have gone mobile-first, and with good reason—people are spending more time and more money on their phones than ever before. For instance, in 2023, an estimated 66% or 2/3rds of all online orders were made from mobile devices. And in 2024, businesses are expected to spend $402 billion on mobile advertising. Mobile apps have become the first choice for users for their online activities in banking, e-commerce, media streaming, social media, etc.

Cross-site scripting (aka XSS) has rightfully claimed its place as one of the most popular web vulnerabilities. Since its first emergence, somewhere in the dark days of the internet, countless vulnerabilities have been found across websites everywhere. Therefore, it comes as no surprise that XSS has been consistently highlighted as a top risk in the OWASP TOP-10 since the list's very first iteration in 2004!
