The objective is to identify exploitable vulnerabilities before malicious actors do, following frameworks like PTES (Penetration Testing Execution Standard), OSSTMM, and NIST SP 800-115.\n\n\n## When to Use\n\n- When conducting security assessments that involve performing external network penetration test\n- When following incident response procedures for related security events\n- When performing scheduled security testing or auditing activities\n- When validating security controls through hands-on testing\n\n## Prerequisites\n\n- Written authorization (Rules of Engagement document signed by asset owner)\n- Defined scope: IP ranges, domains, subdomains, and exclusions\n- Testing environment: Kali Linux or Parrot OS with updated tools\n- VPN/dedicated testing infrastructure to avoid IP blocks\n- Coordination with SOC/NOC for timing windows\n\n## Phase 1 — Pre-Engagement and Scoping\n\n### Define Rules of Engagement\n\n```\nScope:\n - Target IP ranges: 203.0.113.0/24, 198.51.100.0/24\n - Domains: *.target.com, *.target.io\n - Exclusions: 203.0.113.50 (production DB), *.staging.target.com\n - Testing window: Mon-Fri 22:00-06:00 UTC\n - Emergency contact: SOC Lead — +1-555-0100\n - Authorization ID: PENTEST-2025-EXT-042\n```\n\n### Legal Documentation Checklist\n\n| Document | Status | Owner |\n|----------|--------|-------|\n| Master Service Agreement (MSA) |
