Triage and Remediation
Remediation
To remediate secrets that are about to expire and need rotation in Azure using the Azure console, follow these steps:
- Log in to the Azure portal (https://portal.azure.com/).
- Navigate to the Azure Key Vault where the secrets are stored.
- Select the secret that needs to be rotated.
- Click on the “Current Version” tab.
- Click on the “Generate/Import” button.
- Enter the new secret value and click on “Create”.
- Click on the “Save” button to save the new secret value.
- Click on the “Versions” tab.
- Select the previous version of the secret and click on “Disable”.
- Click on the “Save” button to disable the previous version of the secret.
By following these steps, you have successfully rotated the secret and disabled the previous version of the secret in Azure.
To remediate the issue of expiring secrets in Azure using Azure CLI, you can follow these steps:
- Login to your Azure account using Azure CLI by running the following command:
az login
- Once you are logged in, you need to identify the secrets that are about to expire. You can do this by running the following command:
az keyvault secret list --vault-name <your-key-vault-name> --query "[?attributes.exp != null && attributes.exp < now()]"
This command will list all the secrets that are about to expire in your key vault.
- Now that you have identified the secrets that need rotation, you can rotate them by creating new versions of the secrets with updated values. You can do this by running the following command:
az keyvault secret set --vault-name <your-key-vault-name> --name <your-secret-name> --value <your-new-secret-value>
Replace <your-key-vault-name>
, <your-secret-name>
and <your-new-secret-value>
with the appropriate values.
- Once you have created new versions of all the secrets that were about to expire, you can delete the old versions of the secrets by running the following command:
az keyvault secret delete --vault-name <your-key-vault-name> --name <your-secret-name> --version <your-old-secret-version>
Replace <your-key-vault-name>
, <your-secret-name>
and <your-old-secret-version>
with the appropriate values.
-
Repeat steps 3 and 4 for all the secrets that were about to expire.
-
Finally, you can verify that all the secrets have been rotated successfully by running the following command:
az keyvault secret list --vault-name <your-key-vault-name> --query "[?attributes.exp != null && attributes.exp < now()]"
This command should return an empty list, indicating that all the secrets have been rotated successfully.
By following these steps, you can remediate the issue of expiring secrets in Azure using Azure CLI.
To remediate the issue of expiring secrets in AZURE using Python, you can follow these steps:
-
Install the
azure-identity
andazure-keyvault-secrets
packages using pip.pip install azure-identity azure-keyvault-secrets
-
Import the required libraries in your Python code.
from azure.identity import DefaultAzureCredential from azure.keyvault.secrets import SecretClient from datetime import datetime, timedelta
-
Set up the authentication credentials using the
DefaultAzureCredential
class.credential = DefaultAzureCredential()
-
Create a
SecretClient
object using the Azure Key Vault URL and the authentication credentials.keyvault_url = "https://<your-key-vault-name>.vault.azure.net/" secret_client = SecretClient(vault_url=keyvault_url, credential=credential)
-
Retrieve the list of secrets from the Key Vault using the
list_properties_of_secrets
method of theSecretClient
object.secrets = secret_client.list_properties_of_secrets()
-
Iterate over the list of secrets and check if any of them are about to expire (i.e., the
expires_on
property is less than the current time plus a buffer period). If a secret is about to expire, retrieve its current value using theget_secret
method of theSecretClient
object, update its value, and then set the updated value using theset_secret
method of theSecretClient
object.buffer_period = timedelta(days=7) # Set a buffer period of 7 days for secret in secrets: if secret.expires_on <= datetime.utcnow() + buffer_period: secret_value = secret_client.get_secret(secret.name).value # Update the secret value here secret_client.set_secret(secret.name, secret_value)
-
Run the Python script periodically (e.g., daily) using a task scheduler or a cron job to ensure that secrets are rotated before they expire.
These steps should help you remediate the issue of expiring secrets in AZURE using Python.
