Detect when a vault token is created with an excessive time-to-live (TTL) which can be indicative of an adversary maintaining persistence.


Monitoring of vault audit logs where tokens are created with a time-to-live greater than 90000 seconds (25 hours). If the TTL requires modification, clone this rule and update @auth.token_ttl:>90000 in the query.

Triage & Response

  1. Verify max TTL for tokens in the appropriate Vault configuration.
  2. If the max TTL is higher than required, modify the max TTL.
  3. Verify with the token creator to confirm that the high TTL token is legitimate.
  4. Revoke the token if it does not have a legitimate use case.
