CISSP Domain 4: Wi-Fi, WPA3, 5G & Cloud Security
Watch on YouTube On the CISSP, wireless and cloud questions come down to one move: match the control to the requirement, not to whatever is newest. This Domain 4 deep-dive walks Wi-Fi security from broken WEP up through WPA3 and its SAE handshake, separates personal from enterprise authentication, then climbs into mobile, 5G, software-defined networking, and the cloud. With Beth, Erica, Fenrir, and Fatima, we cover the wireless and cloud foundations behind 13% of the current exam, and the question-reading habits that turn BEST and MOST scenarios into quick, defensible picks.
In this video:
- Wi-Fi evolution: why WEP is broken, what AES-CCMP protects, and how WPA3’s SAE stops offline password cracking
- Enhanced Open (OWE) for encrypting open networks with no password
- Personal vs Enterprise: shared PSK versus 802.1X with EAP and a RADIUS server
- Mobile and BYOD: MDM, containerization, and selective wipe of a lost device
- 5G security: network slicing and the concealed subscriber identifier
- SDN control plane vs data plane, plus VPC, stateful security groups, and how a CDN absorbs a DDoS flood
The next video in the series moves into secure network components and topologies, the firewalls, segmentation, and zero-trust designs that tie all of this together. Anchored to the (ISC)2 CISSP Detailed Content Outline effective April 15, 2024.
