Which of the following is the BEST method to validate secure coding techniques against injection and overflow attacks?

Scheduled manual team reviews are inconsistent, subject to human error, and cannot scale to detect the full breadth of injection and overflow vulnerability patterns as effectively or thoroughly as automated tools.

Automated programs such as Dynamic Application Security Testing (DAST) and Static Application Security Testing (SAST) tools continuously scan code against the latest known vulnerability patterns, including SQL injection, buffer overflows, and XSS. These tools can analyze large codebases quickly, apply up-to-date vulnerability databases, and detect issues that manual reviews often miss. Automation ensures consistent, repeatable, and thorough validation without human error or oversight gaps.

Reusing production code routines from other applications introduces inherited vulnerabilities and does not validate or test for injection or overflow weaknesses - it can actually propagate existing flaws into new projects.

Updating code editing tools (such as IDEs with linting plugins) provides limited, surface-level hints about coding style but does not perform comprehensive security testing against the full range of known injection and overflow attack patterns.
