This 1-hour 9-minute webinar explores Domain 4 of the CISSP certification through the lens of Zero-Trust architecture. Dive into Communication & Network Security concepts that move beyond traditional perimeter defenses to address modern threats where attackers pivot laterally once inside networks. Learn how every Domain 4 objective—including secure protocols, network segmentation, VPNs, software-defined networking, network access control, micro-segmentation, and cloud edge controls—maps to the Zero-Trust principle of "never trust, always verify." Gain valuable design patterns, exam-style scenarios, and expert tips to help score high on the CISSP exam while developing practical skills for implementing effective network security in your organization. The session includes actionable guidance, real-world examples, and review questions suitable for both certification candidates and security program leaders.
