Does your organization continuously monitor network communications to detect changes in security postures as part of a zero trust architecture?

Explanation

Continuous trust verification underpins this question, which asks whether you monitor network communications in real time to detect shifts in security posture as part of a zero trust architecture.

In a zero trust model, continuous verification is essential as security postures can change rapidly when devices become compromised, configurations drift, or unauthorized access attempts occur.An acceptable evidence deliverable would include documentation of your network monitoring solution configuration, screenshots of dashboards showing security posture monitoring, logs demonstrating detection of posture changes, and procedures for responding to identified security posture changes.

This could also include reports from tools like Network Access Control (NAC) systems, Endpoint Detection and Response (EDR) solutions, or Security Information and Event Management (SIEM) platforms that specifically monitor for security posture changes.
