Zero Trust is not a one-time setup. It’s a living system that adapts to new threats, shifting user roles, and changes in infrastructure. A quarterly check-in is where weak points surface before they turn into incidents. Skipping it invites drift, misconfiguration, and risk.
A Zero Trust Access Control Quarterly Check-In should be deliberate. The process starts by reviewing your policy definitions. Do they match the current org chart? Are there stale accounts that need to be removed? Are there new resources that should be inside the trust perimeter but aren’t yet?
Next, examine authentication logs for anomalies. Look for patterns like repeated failed login attempts, access from unusual geographies, or devices without current security posture verification. Even if your primary defenses block these attempts, the patterns tell you where to tighten the gates.
Evaluate least privilege permissions. Zero Trust works best when every identity—human and machine—has no more access than required. Over time, roles expand, and permissions accumulate. Quarterly pruning is critical to prevent privilege creep.
Re-test MFA enforcement. Force a review of all MFA mechanisms in use. Replace weaker factors with stronger ones, verify enrollment rates are near 100%, and confirm enforcement policies apply to every sensitive system.
