Security Verification Checklist¶

Version: 1.0.0
Last Updated: January 15, 2026
Purpose: Verify security controls before production deployment

Overview¶

This checklist ensures all security controls are properly implemented and tested. Use this before: - Production deployments - Security audits - Compliance assessments - Release milestones

Status Legend: - ✅ Implemented and Tested - ⚠️ Implemented, Needs Verification - ❌ Not Implemented - 🔄 In Progress

1. Input Validation¶

1.1 Lexer & Parser¶

Verification:

# Run parser tests
cargo test --test entity_parser_tests

# Run fuzzing (5 minutes)
cd fuzz && cargo +nightly fuzz run parser_fuzzer -- -max_total_time=300

1.2 Import Validation¶

Verification:

cargo test --test import_export_test

2. Secret Management¶

2.1 Secret Flow Analysis¶

Verification:

cargo test --test secret_flow_tests
cargo test --test week11_validation_tests -- --nocapture | grep -i secret

2.2 Secret Storage¶

Verification:

# Check generated code for crypto usage
grep -r "bcrypt\|argon2\|aes-256-gcm" compiler/target/debug/generated/

3. Policy Enforcement¶

3.1 Compile-Time Checks¶

Verification:

cargo test --test policy_enforcement_tests
cargo test --test week11_validation_tests -- --nocapture | grep -i policy

3.2 Runtime Enforcement¶

Verification:

cargo test --test week11_runtime_tests
# Inspect generated middleware
cat compiler/target/debug/generated/src/middleware/auth.ts

4. Escape Validation¶

Verification:

cargo test --test escape_validation_tests
# Try compiling example with missing adapter
cargo run -- examples/with_escape.usl

5. Generated Code Security¶

5.1 SQL Injection Prevention¶

Verification:

cargo test --test week10_codegen_tests
# Inspect generated SQL
cat compiler/target/debug/generated/db/queries/*.sql
# Verify parameterization
grep -r "\\$[0-9]" compiler/target/debug/generated/db/queries/

5.2 XSS Prevention¶

Verification:

# Check Content-Type headers
grep -r "Content-Type" compiler/target/debug/generated/src/
# Verify no eval/Function
grep -r "eval\|Function(" compiler/target/debug/generated/src/

5.3 Authentication & Authorization¶

Verification:

cargo test --test week11_runtime_tests
# Check JWT validation
cat compiler/target/debug/generated/src/middleware/auth.ts

6. Layer Boundaries¶

Verification:

cargo test --test layer_boundary_tests
cargo test --test query_test

7. Deployment Security¶

7.1 TLS/HTTPS¶

Verification:

# Check deployment configs
cat compiler/target/debug/generated/deployment/nginx.conf
grep -i "ssl\|tls" compiler/target/debug/generated/deployment/*.yaml

7.2 Container Security¶

Verification:

# Check Dockerfile
cat templates/docker/Dockerfile
# Scan image
docker build -t usl-test .
trivy image usl-test

7.3 Kubernetes Security¶

Verification:

# Check Kubernetes manifests
cat compiler/target/debug/generated/deployment/k8s/*.yaml
kubectl apply --dry-run=client -f compiler/target/debug/generated/deployment/k8s/

8. Dependency Security¶

Verification:

cargo audit
cargo deny check advisories
cargo deny check licenses
cargo outdated

9. Testing & Fuzzing¶

9.1 Test Coverage¶

Verification:

cargo test --all
cargo tarpaulin --out Html
# Open tarpaulin-report.html

9.2 Fuzzing¶

Verification:

cd fuzz
cargo +nightly fuzz run parser_fuzzer -- -max_total_time=300
cargo +nightly fuzz run semantic_fuzzer -- -max_total_time=300
cargo +nightly fuzz run proof_fuzzer -- -max_total_time=300
cargo +nightly fuzz run codegen_fuzzer -- -max_total_time=300

10. Documentation & Compliance¶

Verification:

ls -la docs/security/

Pre-Production Deployment Checklist¶

Before deploying to production, verify:

Critical (Must Fix)¶

• All tests passing (232/232)
• No cargo audit vulnerabilities
• No secrets in code/configs
• TLS enabled and enforced
• Authentication configured
• Authorization policies tested
• Secrets properly encrypted
• Database backups configured
• Monitoring and alerting enabled
• Incident response plan documented

High Priority (Should Fix)¶

• Rate limiting configured
• Brute-force protection enabled
• Key rotation process documented
• Container images scanned
• Kubernetes RBAC configured
• Network policies applied
• Log aggregation configured
• Security headers validated

Medium Priority (Nice to Have)¶

• cargo vet configured
• Read-only root filesystem
• Pod security policies strict
• DDoS protection configured
• Web application firewall (WAF)
• Security training completed
• Penetration testing performed
• Third-party audit completed

Automated Verification¶

Run the complete security verification suite:

# Run all security checks
./scripts/security-audit.sh

# Expected output:
# ✅ cargo audit: 0 vulnerabilities
# ✅ cargo deny: 0 advisories
# ✅ cargo test: 232/232 passing
# ✅ Fuzzing: No crashes
# ✅ Secret scan: No secrets in code
# ✅ Generated code: No vulnerabilities

Continuous Monitoring¶

Daily¶

• Review authentication failures
• Monitor API error rates
• Check resource usage (DoS detection)
• Review security logs

Weekly¶

• Run cargo audit
• Review Dependabot PRs
• Check for new CVEs
• Review access logs

Monthly¶

• Review security metrics
• Update threat model
• Test incident response
• Security training

Quarterly¶

• Dependency review and updates
• Security documentation review
• Penetration testing
• External security audit
