Note: Azure CLI and Powershell use ISO8601 flags to input timespans. Every timespan input will be in the format P(Y,M,D). The leading P is required with it denoting period. The (Y,M,D) are for the duration of Year, Month,and Day respectively. A time frame of 2 years, 2 months, 2 days would be (P2Y2M2D). Remediate from Azure Portal From Azure Portal select the Portal Menu in the top left. Select Key Vaults. Select a Key Vault to audit. Under Objects select Keys. Select a key to audit. In the top row select Rotation policy. Select an Expiry time. Set Enable auto rotation to Enabled. Set an appropriate Rotation option and Rotation time. Optionally set the Notification time. Select Save. Repeat steps 3-11 for each Key Vault and Key. Remediate from Azure CLI Run the following command for each key to update its policy to be auto-rotated: az keyvault key rotation-policy update -n --vault-name --value Note: It is easiest to supply the policy flags in a .json file. An example json file would be: { 'lifetimeActions': [ { 'trigger': { 'timeAfterCreate': '', 'timeBeforeExpiry' : null }, 'action': { 'type': 'Rotate' } }, { 'trigger': { 'timeBeforeExpiry' : '' }, 'action': { 'type': 'Notify' } } ], 'attributes': { 'expiryTime': '' } } Remediate from PowerShell Run the following command for each key to update its policy: Set-AzKeyVaultKeyRotationPolicy -VaultName test-kv -Name test-key -PolicyPath rotation_policy.json Note: It is easiest to supply the policy flags in a .json file. An example json file would be: <# rotation_policy.json { 'lifetimeActions': [ { 'trigger': { 'timeAfterCreate': 'PM', 'timeBeforeExpiry': null }, 'action': { 'type': 'Rotate' } }, { 'trigger': { 'timeBeforeExpiry': 'PD' }, 'action': { 'type': 'Notify' } } ], 'attributes': { 'expiryTime': 'PY' } } #> Default Value: By default, Automatic Key Rotation is not enabled.
