What is API Security Software for Cloud?

API security software is designed to protect APIs from security threats such as unauthorized access, data breaches, and denial-of-service attacks. These tools monitor, authenticate, and secure the connections between APIs and the systems they interact with, ensuring that only authorized users and systems can access the data or services offered by the API. Features typically include encryption, rate limiting, authentication (such as OAuth, JWT), API traffic monitoring, threat detection, and automated security testing. API security software is crucial for businesses that rely on APIs to connect with third-party services, mobile apps, or microservices, as it helps mitigate risks and maintain data integrity.

    Silent Breach

    Your attack surface is the sum of every attack vector that can be used to breach your perimeter defenses. In other words, it is the total quantity of information you are exposing to the outside world. Typically, the larger the attack surface, the more opportunities hackers will have to find a weak link which they can then exploit to breach your network. Professional hackers typically follow the cyber kill chain when attacking a target, and surveying the target's attack surface is normally the very first step in this process; what is known as advanced reconnaissance. Reducing the attack surface can minimize risk further down the cyber kill chain, preventing attacks before they even occur by eliminating potential attack vectors as early as possible. The cyber kill chain is a method of categorizing and tracking the various stages of a cyberattack from the early reconnaissance stages to the exfiltration of data.
