Episode 29 — Lock down wireless networks and remote access pathways

Wireless and remote access collapse distance for attackers, so the exam evaluates whether you treat them as high-risk edges with layered defenses and proof of enforcement. This episode clarifies scope boundaries: business WLANs near the CDE, guest networks, and rogue AP risk. Core controls include strong, enterprise authentication and encryption on authorized wireless, segmentation that keeps WLANs away from the CDE unless explicitly required, and continuous scanning for unauthorized devices. Remote access must traverse hardened gateways with multifactor authentication, device posture checks, and logging that ties sessions to individuals. We connect each control to artifacts: wireless controller configs, certificate inventories, NAC policies, scan results for rogue detection, jump host settings, and session records that include commands where feasible.We examine operational pitfalls the exam often mirrors. Split tunneling that leaves management traffic outside inspection undermines monitoring; correct answers force all remote sessions through controlled choke points with logging and policy. Convenience accounts for vendors or support staff can turn into untraceable pathways; high-quality options use time-bound approvals, unique credentials, and session recording for administrative work. Wireless segmentation fails when shared services bridge zones, or when guest networks route into internal networks via poorly scoped firewall rules; credible remediation tightens routes and validates with tests and controller reports. Troubleshooting includes certificate renewal that, if missed, triggers weak fallback modes; ad-hoc hotspots that dodge corporate policy; and remote tools that punch outbound holes around expected gateways. On test day, select designs that assume hostile airspace and public networks, apply least privilege to radio and remote paths, and back every allowance with monitoring and evidence.
