What is Application Security Testing (AST)?
Application Security Testing (AST) is a critical process within the realm of Information Security and Cybersecurity, focusing on identifying vulnerabilities in software applications. It aims to ensure that applications are protected from various security threats, thereby safeguarding sensitive data and maintaining user trust.
AST encompasses multiple testing methodologies, including static application security testing (SAST), dynamic application security testing (DAST), and interactive application security testing (IAST).
- SAST: Analyzes source code or binaries without executing the program, allowing developers to detect vulnerabilities early in the development lifecycle.
- DAST: Tests running applications to identify runtime vulnerabilities, which ensures that security issues can be found in the deployed environment.
- IAST: Combines elements of both SAST and DAST, providing real-time feedback during application execution by monitoring the code’s behavior.
By incorporating AST into the software development lifecycle (SDLC), organizations can proactively mitigate security risks, reduce the cost of remediation, and enhance the overall security posture of their applications. Regular AST practices are essential for compliance with security standards and regulations.
