Segmentation Incident Response
RCCE students will learn network segmentation design and implementation including VLAN segmentation, micro-segmentation, zero trust network architecture, and segmentation testing. RCCE students will learn to design network segmentation architectures that limit lateral movement, implement VLANs, firewall zones, and software-defined segmentation, apply micro-segmentation to protect high-value assets, verify segmentation effectiveness through penetration testing, monitor inter-segment traffic for policy violations, troubleshoot segmentation-related connectivity issues, and maintain segmentation policies as organizational network architectures evolve across on-premises, cloud, and hybrid environments. This incident response course prepares students to act decisively during security incidents with structured workflows and clear decision frameworks. Building on core knowledge, RCCE students will learn containment, evidence collection, eradication, and recovery procedures specific to this domain. Students practice incident scenarios that build the composure, coordination, and documentation skills essential for effective incident handling.
