# Conducting Network Penetration Test ## When to Use - Assessing the security posture of internal or external network infrastructure before or after deployment - Validating firewall rules, network segmentation, and access controls under realistic attack conditions - Identifying exploitable vulnerabilities in network services, protocols, and configurations - Meeting compliance requirements for PCI-DSS, HIPAA, SOC 2, or ISO 27001 that mandate periodic penetration testing - Evaluating the effectiveness of IDS/IPS, SIEM, and SOC detection capabilities against real attack traffic **Do not use** for testing networks without explicit written authorization from the asset owner, against production systems without a pre-approved change window and rollback plan, or for denial-of-service testing unless explicitly scoped and authorized. ## Prerequisites - Signed Rules of Engagement (RoE) document specifying target IP ranges, excluded hosts, testing hours, and emergency contacts - Written authorization letter (get-out-of-jail letter) from the network owner - Dedicated testing laptop with Kali Linux or equivalent distribution with up-to-date tools - VPN or direct network access to the target scope as defined in the RoE - Out-of-band communication channel with the client's incident response team - Scope document listing in-scope IP ranges, domains, and any explicitly excluded systems (medical devices, SCADA, critical infrastructure) ## Workflow ### Step 1: Pre-Engagement and Scope Val...
