🔒 Add Security Scanning (cargo audit + Dependabot)

Overview

Implement comprehensive security scanning to automatically detect vulnerabilities in dependencies and ensure VanitySSH maintains zero security issues.

Tasks

1. Cargo Audit Integration

• Add cargo audit to CI pipeline
• Configure audit to fail CI on vulnerabilities
• Add audit job to existing workflow
• Test with known vulnerable dependency

2. Dependabot Configuration

• Create .github/dependabot.yml configuration
• Configure for Cargo ecosystem updates
• Set update frequency (weekly)
• Configure auto-merge for patch updates

3. Security Workflow

• Create dedicated security.yml workflow
• Add SARIF upload for security results
• Configure security notifications
• Add security badge to README

Acceptance Criteria

• CI fails when vulnerabilities are detected
• Dependabot automatically creates update PRs
• Security scan results are visible in GitHub Security tab
• Documentation updated with security practices

Implementation Details

Cargo Audit Job

- name: Security audit
  run: |
    cargo install --locked cargo-audit
    cargo audit

Dependabot Config

version: 2
updates:
  - package-ecosystem: "cargo"
    directory: "/"
    schedule:
      interval: "weekly"

Testing

• Test with vulnerable dependency
• Verify Dependabot PR creation
• Confirm security tab integration
• Test CI failure scenarios

Timeline

Estimate: 1-2 days
Priority: High
Phase: 1

📊 Analysis Complete - Ready for Implementation

Current State Assessment

✅ Clean Security Baseline: No vulnerabilities detected in current dependencies
✅ Modern Dependencies: Recently updated to latest versions in previous PR
✅ Cryptographic Focus: Tool uses security-critical libraries (ed25519-dalek, rand)
✅ CI Infrastructure: Existing robust CI pipeline ready for extension

Implementation Strategy: Incremental Security Integration

Phase A: Basic CI Integration (30 min) ⬅️ STARTING HERE

• Add security job to existing ci.yml
• Run only on ubuntu-latest for efficiency
• Fail CI pipeline on any vulnerabilities
• Test with vulnerable dependency

Phase B: Dependabot Setup (15 min)

• Create .github/dependabot.yml
• Weekly Cargo ecosystem updates
• Configure for security updates

Phase C: Advanced Security Workflow (30 min)

• Dedicated security.yml workflow
• SARIF upload for GitHub Security tab
• Scheduled security scans

Phase D: Documentation & Validation (15 min)

• Security badge in README
• Update CLAUDE.md practices
• End-to-end validation

Why This Approach

• LOW RISK: Pure additive changes, zero code modification
• HIGH VALUE: Immediate security protection for crypto tool
• FAST: ~90 minutes total implementation time
• FOUNDATION: Establishes security-first practices

Next Steps

• Analysis complete
• Create feature branch
• Implement Phase A (CI integration)
• Test security scanning
• Implement remaining phases

Starting implementation now... 🚀

[kengggg]

✅ Phase A Complete: Basic CI Security Scanning

Implementation Summary

• Security job added to CI pipeline using cargo-audit
• Dependency chain: security → check → build (all jobs depend on security passing)
• Optimized performance with Rust caching for cargo-audit installation
• Tested thoroughly with both clean and vulnerable dependencies

Technical Details

security:
  runs-on: ubuntu-latest
  steps:
    - name: Checkout code
    - name: Install Rust toolchain  
    - uses: Swatinem/rust-cache@v2 (with cargo-audit caching)
    - name: Install cargo-audit
    - name: Run security audit (fails CI on vulnerabilities)

Validation Results

✅ Clean Dependencies: No vulnerabilities detected in current codebase
✅ Failure Testing: Confirmed CI fails with vulnerable dependencies (tested with time = "0.1.43")
✅ All Tests Pass: Existing functionality unaffected
✅ Performance: Caching reduces security job runtime

Branch & PR

• Branch: feature/security-scanning-phase-a
• Commit: 139b2ed - Implement Phase A: Basic CI Security Scanning
• Ready for: Pull request and merge to main

Next Steps

• Phase B: Dependabot setup (15 min)
• Phase C: Advanced security workflow (30 min)
• Phase D: Documentation & validation (15 min)
