Secure Code Review
Secure Code Review looks at code through a security lens – finding vulnerabilities before they can be merged, deployed, or exploited.
What Is Secure Code Review?
Secure Code Review is a structured review of source code specifically focused on identifying security vulnerabilities, misconfigurations, and coding patterns that introduce risk. It evaluates code against known vulnerability classes – such as those catalogued in the OWASP Top 10 – and against the specific security requirements of the application being built.
Standard code review evaluates correctness, readability, and performance. Secure code review applies an additional lens: does this code introduce a security vulnerability? The analysis covers input handling, authentication logic, authorisation controls, data exposure risks, dependency usage, cryptographic implementation, and the handling of sensitive information.
Secure code review can be performed manually by a developer with security expertise, but manual-only review does not scale. Automated security scanning tools provide consistent baseline coverage – flagging known vulnerability patterns across every pull request. AI-powered tools extend this by reasoning about how code is used in context, identifying vulnerabilities that pattern matching alone would miss.
The most effective secure code review programmes combine automated scanning with periodic manual deep-dive reviews, applying human security expertise where it adds the most value – on complex authentication flows, cryptographic implementations, and areas of the codebase that handle particularly sensitive data.
