Describe the process of integrating security scanning into a CI/CD pipeline and the types of vulnerabilities that should be addressed at each stage.

Integrating security scanning into a CI/CD pipeline, often referred to as DevSecOps, involves automating security checks at various stages to identify and mitigate vulnerabilities early in the development lifecycle. This proactive approach reduces the risk of deploying vulnerable code to production and strengthens the overall security posture. The process typically involves several stages, each addressing different types of vulnerabilities. 1. Static Application Security Testing (SAST): SAST, also known as "white box testing," analyzes the source code for potential vulnerabilities without executing the code. This is typically performed early in the CI/CD pipeline, such as during code commit or build phases. Vulnerabilities Addressed: Code Quality Issues: Identifies coding errors, style violations, and potential bugs that could lead to security vulnerabilities. Common Weakness Enumeration (CWE): Detects common software weaknesses like buffer overflows, SQL injection vulnerabilities, cross-site scripting (XSS), and insecure configuration settings. OWASP Top 10: Scans for vulnerabilities listed in the OWASP Top 10, such as injection flaws, broken authentication, sensitive data exposure, and XML external entities (XXE). Security Best Practices Violations: Ensures adherence to secure coding practices, such as proper input validation, output encoding, and secure cryptography usage. Example: Using SonarQube or Checkmarx in the build phase to scan the source code for potential SQL injection vulnerabilities. If a vulnerability is detected, the build is automatically failed, preventing the vulnerable code from being merged into the main branch. 2. Software Composition Analysis (SCA): SCA analyzes the open-source and third-party components used in the application to identify known vulnerabilities and license compliance issues. This is crucial because applications often rely on numerous external libraries and frameworks, which can contain vulnerabilities. Vulnerabilities Addressed: Known Vulnerabilities (CVEs): Detects vulnerabilities listed in public databases like the National Vulne....
