CISSP Domain 3: Cloud, ICS, IoT & Container Vulnerabilities
Every system architecture fails in its own signature way - and on the CISSP, Domain 3.5 tests whether you can name the weakness from the system type alone. This deep-dive walks the full catalog: database aggregation versus inference (and polyinstantiation as the fix), industrial control systems and the Stuxnet lesson, the cloud shared responsibility model, IoT and the Mirai botnet, container escape, VM escape, and AI model poisoning.
With Grace, River, Sara, and Liam, we turn a long list of system types into a single test-taking reflex: identify the architecture 1st, find the boundary that can break, and the right answer falls out. Anchored to the (ISC)2 CISSP Detailed Content Outline effective April 15, 2024, with sourcing from NIST SP 800-145 (cloud), NIST SP 800-82 (operational technology), and CISA.
In this video:
- Aggregation versus inference, and why the verb in the scenario decides the answer
- Polyinstantiation and the database controls that close the inference gap
- Why ICS and SCADA put availability and safety ahead of patching
- The cloud shared responsibility split: security OF versus IN the cloud
- Container escape, VM escape, and the shared-infrastructure thread that connects them
- How model poisoning and adversarial inputs make AI its own vulnerability class
