Semgrep can identify selected security patterns in mobile source code. Evaluate rule coverage and supported language features alongside the finding's actual application impact.
Evaluation approach
Available languages and analysis capabilities depend on the edition. Project-specific rules can look for weakened production TLS checks or embedded secrets. Test the language constructs each rule covers.
Application example
Build a small dataset of safe and unsafe examples before making a rule a CI gate. Measure false positives and missed cases.
Limits and considerations
No matches does not prove a program is secure. Dynamic behavior and native code may need separate review.
Give each rule a security question
Test a rule against a real defect and a similar-looking correct implementation. Simple keyword matching can miss context. State the language and analysis level used.
For RASP integrations, look for unsafe error paths, excessive logging and configuration mistakes. Give developers a specific location and explanation. Source scanning remains distinct from runtime tampering tests.
Checks and decisions
- Record rule versions
- Justify exceptions
- Rescan fixes
Use Semgrep to give developers actionable feedback. It does not take over RASP's production role.
