Security Audit

Priority: P0 (CRITICAL)

? Security Probing Protocol

1. Hardcoded Secrets (Critical)

Scan for plain-text keys, passwords, and tokens in code.

grep -riE "(password|apiKey|api_key|secret|private_key|token)\s*=\s*['\"][^'\"]{6,}" \
  . --exclude-dir={node_modules,dist,build,.git} -l

2. Data Leakage in Logs (PII/Secrets)

Identify sensitive info printed to logs or stdout.

• Node/TS: grep -rE "console\.(log|error|warn)" . --include="*.ts" --include="*.js" | grep -iE "password|token|secret|private"
• Go: grep -rE "log\.(Print|Printf|Println|Fatal)" . --include="*.go" | grep -iE "password|token|secret"
• Dart/Flutter: grep -rE "print\(|debugPrint\(" . --include="*.dart" | grep -iE "password|token|secret"
• Java/Spring: grep -rE "log(ger)?\.(info|debug|warn|error)" . --include="*.java" | grep -iE "password|token|secret"

3. Injection Surface (SQL / Command)

Detect raw string concatenation in queries or system commands.

grep -rE "\+.*SELECT|\+.*INSERT|\+.*UPDATE|\+.*DELETE|query\(.*\+|fmt\.Sprintf.*SELECT" \
  . --include="*.ts" --include="*.js" --include="*.go" --include="*.java" --include="*.py"

4. Auth Coverage vs Exposure

Compare total routes vs protected endpoints.

• NestJS: total=$(grep -r "@(Get|Post|Put|Delete|Patch)" . | wc -l); guarded=$(grep -r "@(UseGuards|Auth)" . | wc -l)
• Spring: total=$(grep -r "@(GetMapping|PostMapping|PutMapping)" . | wc -l); guarded=$(grep -r "@(PreAuthorize|Secured)" . | wc -l)
• Go: total=$(grep -rE "(GET|POST|PUT|DELETE)" . | wc -l); guarded=$(grep -rE "(middleware|auth|jwt|guard)" . | wc -l)

5. Dependency Audit (CVE Scan)

• Node: npm audit --audit-level=high
• Dart/Flutter: dart pub outdated --json
• Go: go list -m -u all | grep "\["
• Java: mvn dependency:list or ./gradlew dependencies
• Python: pip-audit
• Rust: cargo audit

6. Infrastructure Hardening

grep -rE "^FROM .+:latest|^USER root|curl.*sh.*|ADD http" . --include="Dockerfile"

⚖️ Scoring Impact

Finding	Threshold	Severity	Deduction
Hardcoded Secrets	Any match	? P0	-25
Plain-text PII in Logs	Any match	? P0	-20
Unguarded Routes > 20%	> 0.2	? P0	-15
Raw SQL Concatenation	Any match	? P1	-10
Response Leakage (Stack)	> 0	? P1	-10

[!CAUTION] A ? P0 finding immediately caps the Security score at 40/100.
