Secure Code Review
OWASP calls code review the single most effective technique for finding security flaws, and in our experience that holds. A tester probing from outside can miss a branch of code that only runs for one tenant. Reading the source, you see it, along with the hard-coded key two files over.
Why Secure Code Review?
Most serious application bugs are small. A SQL query built with string concatenation, a JWT library set to accept the none algorithm, a file upload that trusts the extension. Each is a few lines, and each can hand an attacker the database.
Reviewing source also shows design problems a black-box test cannot, like authorisation checked in the controller for one route and forgotten on its twin.
Vulnerability Detection
Injection, deserialisation, path traversal and the rest of the CWE Top 25, traced from user input to the dangerous call.
Sensitive Data Exposure
Secrets in config files and git history, tokens written to logs, personal data sent where it should not go.
Design Flaw Analysis
Trust boundaries, session handling and multi-tenant isolation. Static analysers rarely understand any of these.
Compliance Verification
Findings mapped to OWASP ASVS requirements and, where relevant, PCI DSS or GDPR obligations.
Our Code Review Methodology
Tools first for coverage, people for judgement. Neither works well alone.
Scope Definition
We agree which repositories and commits are in scope and read the architecture notes, if there are any.
Automated Analysis
Semgrep, CodeQL and a dependency audit. Expect hundreds of hits, most of them noise.
Manual Review
Engineers trace login, password reset, payments and admin functions by hand, and triage every tool hit.
Report & Remediation
Each finding has a file and line number, a CWE, a CVSS score and a suggested patch.
