Control: 8.1 Ensure that the expiration date is set on all keys

Description

It is recommended that all keys in Azure Key Vault have an expiration time set. Azure Key Vault enables users to store and use cryptographic keys within the Microsoft Azure environment. The exp (expiration time) attribute identifies the expiration time on or after which the key MUST NOT be used for a cryptographic operation.

As default, keys never expire. It is thus recommended that keys be rotated in the key vault and set an explicit expiration time for all keys.

Remediation

From Console

  1. Login and go to Key vaults.
  2. For each Key vault, go to Settings section and click on Keys.
  3. Make sure Status is Enabled.
  4. Set an appropriate Expiration Date on all keys.

From Command Line
