Expiration Date Is Not Set For Key Vault Key

Overview

Ensure that all Keys in Azure Key Vaults have an expiration date set.

Azure Key Vault enables users to store and use cryptographic keys within the Microsoft Azure environment. The exp (expiration date) attribute identifies the expiration date on or after which the key MUST NOT be used for a cryptographic operation. By default, keys never expire. It is thus recommended that keys be rotated in the key vault and set an explicit expiration date for all keys. This ensures that the keys cannot be used beyond their assigned lifetimes.

Keys cannot be used beyond their assigned expiration dates. Keys need to be rotated periodically wherever they are used.
