Identity-Aware Proxy (IAP) password rotation policies are not optional. They control how often credentials change, how they are stored, and how they are invalidated. Strong rotation rules shrink the attack window when a password is stolen, reused, or exposed. Weak rules leave credentials static, giving intruders time to move unseen.
An effective rotation policy begins with the scope. Decide which accounts, services, and APIs live behind your IAP. Apply rotation to both human and service accounts. Include integration secrets if the proxy handles machine-to-machine authentication. Avoid partial coverage; weak spots become breach vectors.
Set rotation frequency according to risk. High-value endpoints call for daily or weekly rotation. Lower-risk components may rotate monthly, but never indefinitely. Automate enforcement. A policy that relies on human reminders will fail. Use scripts or orchestration tools connected to your IAP to generate and push new credentials automatically.
Implement immediate revocation. When a password rotates, the old credential must die in all caches and sessions. Configure the Identity-Aware Proxy to reject stale tokens on first use. This stops attackers who try to exploit grace periods.
