What is Security Testing?
Security Testing evaluates a software system to protect it from unauthorized access, data breaches, and other security threats. It ensures confidentiality, integrity, and availability of the application.
Identify potential security vulnerabilities, ensure data confidentiality and integrity, and protect against threats like SQL injection, XSS, CSRF, and other cyber attacks.
Prevents security breaches, protects sensitive user data, enhances user trust and reliability, and ensures compliance with security regulations.
Time-consuming and complex process, requires highly skilled security testers, and may not detect all vulnerabilities or zero-day attacks.
Security Testing Process
- Identify security requirements and threats
- Prepare security test cases and scenarios
- Perform vulnerability assessment and scanning
- Conduct penetration testing (ethical hacking)
- Fix identified issues and re-test for security
Real-world Example
Example: Testing a banking application for SQL injection and unauthorized access vulnerabilities before production deployment to prevent data theft.
Best Practices for Security Testing
Perform security testing early in SDLC (Shift Left)
Use automated scanning tools with manual testing
Regularly update security policies and threat models
Maintain detailed logs and reports for audit purposes
