As a developer, you need to be familiar with various security measures to protect your applications from potential vulnerabilities. Among the security testing techniques that you need to be aware of are Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), Interactive Application Security Testing (IAST), and Runtime Application Self-Protection (RASP).
SAST: Static Application Security Testing
SAST is a type of security testing that analyzes an application’s source code or compiled bytecode to identify potential security vulnerabilities. SAST is usually performed in the early stages of software development, making it an essential tool for developers to prevent vulnerabilities from being introduced into the application’s code. The primary advantage of SAST is that it can detect vulnerabilities in the source code before the application is deployed.
DAST: Dynamic Application Security Testing
DAST is a type of security testing that examines an application’s running state to identify vulnerabilities. It involves sending requests to the application to simulate real-world attacks and identify potential vulnerabilities. The primary advantage of DAST is that it can detect vulnerabilities in the application’s runtime environment that might have been missed by SAST.
IAST: Interactive Application Security Testing
IAST is a type of security testing that combines elements of both SAST and DAST. It examines the application’s running state like DAST, but it also provides more in-depth insights into the application’s code like SAST. IAST can detect vulnerabilities in the code as well as the runtime environment, making it an essential tool for developers to prevent vulnerabilities from being introduced into the code.
RASP: Runtime Application Self-Protection
RASP is a type of security testing that monitors an application’s runtime behavior to identify potential attacks and take appropriate action. It is usually deployed as an agent within the application’s runtime environment, allowing it to monitor and protect the application against various attacks. RASP can detect and block attacks in real-time, making it an essential tool for applications that handle sensitive data.
As a developer, you need to be familiar with various security testing techniques like SAST, DAST, IAST, and RASP. Each of these techniques has its strengths and weaknesses, and you need to determine which technique to use based on your application’s requirements. By being familiar with these techniques, you can better protect your application against potential vulnerabilities and provide a more secure experience for your users.
