Application security testing is a critical process that aids organizations in identifying and addressing vulnerabilities and weaknesses in their software applications. There are various types of application security testing methods available, each serving a unique purpose in ensuring the overall security of an application.

Static application security testing (SAST) is a type of testing that analyzes the source code or compiled version of an application without executing it. It helps identify potential security flaws by scanning the code for known vulnerabilities and coding errors.

Dynamic application security testing (DAST) involves testing the running application for vulnerabilities by simulating real-world attacks. DAST examines the application from the outside, focusing on its inputs and outputs, and identifies potential security weaknesses.

Interactive application security testing (IAST) combines the benefits of both SAST and DAST. It analyzes the application in real-time during runtime, providing detailed insights into vulnerabilities and potential exploits.

Mobile application security testing is specifically focused on securing mobile applications. With the increasing use of mobile devices, it has become essential to ensure the security of mobile applications. Mobile app security testing involves testing the application for vulnerabilities, including insecure data storage, weak authentication, and inadequate encryption.

Software composition analysis (SCA) is a method that examines the open-source components and libraries used in an application. It helps identify any known vulnerabilities or licensing issues that may exist in these components, allowing organizations to take appropriate actions to mitigate risks.

Runtime application self-protection (RASP) is a security technology that protects applications from within. It monitors the application's behavior during runtime and detects and prevents attacks in real-time. RASP helps organizations defend against various threats, including code injection, SQL injection, and cross-site scripting.
