NAC Hardening Workshop
RCCE students will learn network access control architectures including 802.1X authentication, RADIUS/TACACS+ integration, device posture assessment, guest networking, and network segmentation enforcement. RCCE students will learn to design and deploy NAC solutions that enforce access policies based on user identity, device health, and location, configure pre-admission and post-admission controls, implement remediation workflows for non-compliant devices, troubleshoot NAC authentication failures, detect and respond to NAC bypass attempts, integrate NAC with endpoint management platforms, and maintain NAC policies as organizational requirements evolve. This hands-on hardening course focuses on reducing attack surface through practical configuration changes and security guardrails. Starting from foundational concepts, RCCE students will learn to apply hardening baselines, validate configurations, and measure the security improvement achieved. Students walk away with actionable hardening checklists and the skills to maintain hardened configurations as environments evolve.
