Event Information

  1. The google.cloud.secretmanager.v1.SecretManagerService.DestroySecretVersion event in GCP for SecretManager indicates that a specific version of a secret has been destroyed or permanently deleted.

  2. This event signifies that the secret version can no longer be accessed or recovered, and any data associated with that version is irretrievable.

  3. It is important to note that destroying a secret version is a permanent action and should be done with caution, as it cannot be undone. This event can be useful for auditing and tracking purposes, ensuring that sensitive information is properly managed and disposed of when necessary.

​
Examples

  1. Unauthorized access: If the DestroySecretVersion operation in GCP’s Secret Manager is not properly secured, it can potentially allow unauthorized users to delete secret versions. This can lead to a compromise of sensitive information and a breach of security.

  2. Data loss: If the DestroySecretVersion operation is misused or executed incorrectly, it can result in the permanent deletion of secret versions. This can lead to data loss and potentially impact the availability and integrity of the secrets stored in Secret Manager.

  3. Lack of auditability: If the DestroySecretVersion operation is not properly logged and audited, it can make it difficult to track and investigate any unauthorized or accidental deletions. This can hinder the ability to identify and mitigate security incidents, as well as comply with regulatory requirements for data protection and access control.

Remediation

​
Using Console

  1. Identify the issue: Use the GCP console to navigate to the SecretManager service and identify the specific secret that needs to be remediated.

  2. Update the secret: Select the secret and click on the “Edit” button. Update the secret value with a strong and secure value that complies with your organization’s security policies. Ensure that the new value is not easily guessable and follows best practices for password complexity.

  3. Rotate the secret: If the secret has been compromised or if it is recommended to rotate secrets periodically, generate a new secret value. In the GCP console, click on the “Rotate” button to generate a new secret value. Make sure to update any applications or services that rely on this secret with the new value to ensure uninterrupted functionality.

Note: It is important to follow your organization’s security policies and best practices when remediating secrets in GCP SecretManager. Additionally, consider implementing access controls, monitoring, and auditing mechanisms to ensure the ongoing security of your secrets.

Using CLI

To remediate the issues related to GCP Secret Manager using GCP CLI, you can follow these steps:

  1. Enable Secret Manager API:

    • Run the following command to enable the Secret Manager API: 
      gcloud services enable secretmanager.googleapis.com

  2. Create a secret:

    • Use the following command to create a new secret: 
      gcloud secrets create [SECRET_NAME] --replication-policy automatic

  3. Add a secret version:

    • To add a new version to an existing secret, use the following command: 
      gcloud secrets versions add [SECRET_NAME] --data-file=[PATH_TO_SECRET_FILE]

Note: Replace [SECRET_NAME] with the desired name for your secret, and [PATH_TO_SECRET_FILE] with the path to the file containing the secret data.

​
Using Python

To remediate the issues related to GCP Secret Manager using Python, you can follow these steps:

  1. Accessing Secrets:

    • Use the google-cloud-secret-manager library to interact with Secret Manager in Python.
    • Install the library using pip install google-cloud-secret-manager.
    • Authenticate with GCP by setting up the appropriate credentials. You can use Application Default Credentials (ADC) or provide explicit credentials.
    • Use the following code snippet to access a secret: 
      from google.cloud import secretmanager

def access_secret(project_id, secret_id):
    client = secretmanager.SecretManagerServiceClient()
    secret_name = f"projects/{project_id}/secrets/{secret_id}/versions/latest"
    response = client.access_secret_version(request={"name": secret_name})
    return response.payload.data.decode("UTF-8")

  2. Storing Secrets:

    • Use the same google-cloud-secret-manager library to store secrets in Secret Manager.
    • Install the library using pip install google-cloud-secret-manager.
    • Authenticate with GCP as mentioned in the previous step.
    • Use the following code snippet to store a secret: 
      from google.cloud import secretmanager

def store_secret(project_id, secret_id, secret_value):
    client = secretmanager.SecretManagerServiceClient()
    parent = f"projects/{project_id}"
    secret = {"name": f"{parent}/secrets/{secret_id}"}
    response = client.create_secret(request={"parent": parent, "secret": secret})
    version = response.name.split("/")[3]
    payload = secret_value.encode("UTF-8")
    response = client.add_secret_version(
        request={"parent": secret["name"], "payload": {"data": payload}}
    )
    return version

  3. Managing Access Control:

    • Use IAM (Identity and Access Management) to manage access control for Secret Manager.
    • Grant appropriate roles to users or service accounts to control their access to secrets.
    • Use the following code snippet to grant a role to a user or service account: 
      from google.cloud import secretmanager_v1beta1 as secretmanager

def grant_secret_access(project_id, secret_id, member, role):
    client = secretmanager.SecretManagerServiceClient()
    resource = f"projects/{project_id}/secrets/{secret_id}"
    policy = client.get_iam_policy(request={"resource": resource})
    binding = next((b for b in policy.bindings if b.role == role), None)
    if binding:
        binding.members.append(member)
    else:
        binding = secretmanager.Binding(role=role, members=[member])
        policy.bindings.append(binding)
    client.set_iam_policy(request={"resource": resource, "policy": policy})
