Episode 35 — Rotate keys, manage escrow, and revoke safely
This episode focuses on key rotation, escrow, and revocation, because the ISA exam often tests whether you understand how key lifecycle events prevent long-term exposure while preserving business continuity. You’ll define rotation as more than “changing a password” by explaining key versioning, cryptoperiods, re-encryption strategies, and how applications safely adopt new keys without downtime. We’ll cover escrow concepts carefully, including when escrow is appropriate, how escrow controls must be stronger than the systems they protect, and how governance prevents escrow from becoming a convenient backdoor for unauthorized decryption. You’ll learn what triggers revocation, such as compromise indicators, personnel changes, or certificate expiration, and how revocation planning avoids breaking integrations or losing access to legitimately encrypted data. Troubleshooting examples will include applications that cannot re-encrypt quickly, mismanaged certificate chains that cause outages, and missing ownership for rotation schedules, along with best practices for documenting rotation events, approvals, and audit logs so the process is both secure and assessable.
