Security Scanning Workflows

Pre-Push Security Check

Before any push to remote, run this sequence:

1. gitleaks detect --verbose — scan for leaked secrets
2. trivy fs --severity HIGH,CRITICAL . — filesystem vulnerability scan
3. osv-scanner --lockfile=<lockfile> — dependency vulnerability check

Container Security

1. trivy image <image> — scan container image
2. syft <image> — generate SBOM (Software Bill of Materials)
3. grype <image> — scan SBOM/image for known vulnerabilities
4. crane manifest <image> — inspect remote image without pulling
5. cosign verify <image> — verify image signature
6. dive <image> — check image layer efficiency
7. hadolint Dockerfile — lint Dockerfile for best practices

Infrastructure Security

1. trivy config . — scan Terraform/CloudFormation for misconfigs
2. tflint — lint Terraform files
3. opengrep scan -f auto . — static analysis

Network Reconnaissance

1. subfinder -d <domain> — passive subdomain enumeration
2. dnsx -l subdomains.txt -resp — bulk DNS resolution
3. httpx -l hosts.txt -sc -title -tech-detect — probe for live HTTP services
4. katana -u <url> — crawl with JS rendering for hidden endpoints
5. nmap -sV -sC <target> — service version detection
6. nuclei -u <target> — template-based vuln scanning
7. nikto -h <target> — web server scanning
8. ffuf -u <url>/FUZZ -w <wordlist> — directory fuzzing

Supply Chain Security

1. syft dir:. — generate SBOM for project directory
2. grype sbom:./sbom.json — scan SBOM for known CVEs
3. grype dir:. — scan project directly for vulnerable dependencies

TLS & Certificate Debugging

1. step certificate inspect <cert.pem> — view certificate details
2. step certificate inspect https://<domain> — inspect remote TLS cert
3. step certificate create — generate self-signed certs for testing

System Hardening

1. lynis audit system — full system security audit
2. Review output and address findings by severity

Rules

• NEVER scan targets you don't own or have authorization for
• Always use --help before running any security tool
• Report findings clearly with severity levels
• Suggest remediations alongside findings
