# Security Audit

## **Priority: P0 (CRITICAL)**

## 1. Scan for Hardcoded Secrets

See [implementation examples](references/implementation.md) for secrets scanning commands.

## 2. Detect Data Leakage in Logs

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"`
- **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. Map Injection Surfaces

Detect raw string concatenation in queries or system commands.

See [implementation examples](references/implementation.md) for injection surface detection.

## 4. Measure Auth Coverage vs Exposure

Compare total routes against 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. Run Dependency CVE Scans

- **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- **Dart/Flutter**: `dart pub outdated --json`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. Audit Infrastructure Hardening

See [implementation examples](references/implementation.md) for infrastructure hardening checks.

## 7. Detect Adversarial Entry Points (RCE/SSRF/Path Traversal)

Identify where user input reaches dangerous sinks without sanitization.

- **Path Traversal**: `grep -rE "path\.join\(|os\.path\.join\(" . | grep -vE "path\.resolve|path\.normalize"`
- **SSRF**: `grep -rE "axios\.get\(|http\.Get\(|fetch\(" . | grep -vE "['\"]https?://" `
- **BOLA/IDOR**: `grep -rE "findById\(|findOne\(" . | grep -viE "tenant|owner|user_id"`

## 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**: P0 finding immediately caps Security score at 40/100.

## Anti-Patterns

- **No applying generic patterns over project-specific rules**: Respect existing security constraints.
- **No ignoring error handling or edge cases**: Audit must cover boundary conditions.
