Description

Ensure that all Secrets in Role Based Access Control (RBAC) Azure Key Vaults have an expiration date set.

Rationale

The Azure Key Vault enables users to store and keep secrets within the Microsoft Azure environment. Secrets in the Azure Key Vault are octet sequences with a maximum size of 25k bytes each. The exp (expiration date) attribute identifies the expiration date on or after which the secret MUST NOT be used. By default, secrets never expire. It is thus recommended to rotate secrets in the key vault and set an explicit expiration date for all secrets. This ensures that the secrets cannot be used beyond their assigned lifetimes.

Impact

Secrets cannot be used beyond their assigned expiry date respectively. Secrets need to be rotated periodically wherever they are used.

Audit

From Azure Portal

1. Go to Key vaults.
2. For each Key vault, click on Secrets..
3. In the main pane, ensure that the status of the secret is Enabled.
4. For each enabled secret, ensure that an appropriate Expiration date is set.

Remediation

From Azure Portal

1. Go to Key vaults.
2. For each Key vault, click on Secrets.
3. In the main pane, ensure that the status of the secret is Enabled.
4. For each enabled secret, ensure that an appropriate Expiration date is set.

From Azure CLI

Update the Expiration date for the secret using the below command:

az keyvault secret set-attributes --name <secretName> --vault-name <vaultName> --expires Y-m-d'T'H:M:S'Z'

Note: To view the expiration date on all secrets in a Key Vault using Microsoft API, the List Key permission is required.

To update the expiration date for the secrets:

1. Go to the Key vault, click on Access Control (IAM).
2. Click on Add role assignment and assign the role of Key Vault Secrets Officer to the appropriate user.

From PowerShell

Set-AzKeyVaultSecretAttribute -VaultName <Vault Name> -Name <Secret Name> -Expires <DateTime>

One example is malware that infects computers and encrypts data, both on the infected computer and any connected storage, including (corporate) networks and cloud storage. Such attacks reinforce the importance of protecting the backup environment in the event that the production environment is compromised. Common techniques to achieve this include network segmentation, highly restricted and segregated access controls and network traffic flow restrictions.		34	36
