Zero Trust moves away from implicit trust based on network location. Palo Alto Networks features enable explicit verification and deep inspection: - Option A (Correct): App-ID allows policies to be based on what the traffic is (the application), verifying the application identity explicitly, moving beyond port-based trust. - Option B (Correct): User-ID and Device-ID verify who is initiating the traffic and what device they are using, allowing policies to be tied directly to user and device identity and posture, a core tenet of explicit verification. - Option C (Correct): Content-ID features embody the 'Assume Breach' principle by inspecting all relevant allowed traffic (not just perceived threats) for malware, exploits, sensitive data, and malicious URLs. This assumes threats can exist within legitimate applications. - Option D (Correct): SSL Decryption is critical because a vast majority of modern threats and data exfiltration attempts occur over encrypted channels. Decryption is necessary to apply App-ID (more accurately) and Content-ID to encrypted traffic, enabling the 'Verify Explicitly' and 'Assume Breach' principles for this traffic. - Option E (Incorrect): While security zones are fundamental for network segmentation and policy structure, they primarily align with a segment- based approach, which is a building block, but less directly representative of the identity-aware, application-aware, content-inspecting principles at the core of modern Zero Trust compared to the other options.
