Event Information

  • The google.cloud.secretmanager.v1.SecretManagerService.DeleteSecret event in GCP for SecretManager indicates that a secret has been deleted from the Secret Manager service.
  • This event signifies that the specified secret, along with its associated versions and metadata, has been permanently removed from the Secret Manager.
  • It is important to note that this event does not trigger any additional actions or notifications by default, but it can be used for auditing purposes or to track the deletion of secrets in the Secret Manager service.

​
Examples

  • Unauthorized access: If security is impacted with google.cloud.secretmanager.v1.SecretManagerService.DeleteSecret in GCP for SecretManager, it could potentially allow unauthorized users to delete secrets. This can lead to unauthorized access to sensitive information stored in those secrets, compromising the security of the system.

  • Data loss: If security is impacted with google.cloud.secretmanager.v1.SecretManagerService.DeleteSecret in GCP for SecretManager, it could result in accidental or malicious deletion of secrets. This can lead to data loss and potential disruption of services that rely on those secrets for authentication, encryption, or other critical operations.

  • Audit trail compromise: If security is impacted with google.cloud.secretmanager.v1.SecretManagerService.DeleteSecret in GCP for SecretManager, it could compromise the integrity of the audit trail. The deletion of secrets may not be properly logged or tracked, making it difficult to identify and investigate any unauthorized or malicious activities. This can hinder incident response and forensic analysis in case of security incidents.

Remediation

​
Using Console

  1. Identify the issue: Use the GCP console to navigate to the SecretManager service and identify the specific issue or vulnerability that needs to be remediated. This could include misconfigured access controls, weak encryption settings, or any other security concern.

  2. Modify secret settings: Once the issue has been identified, navigate to the specific secret in the GCP console. Modify the settings to ensure that the secret is properly secured. This may involve adjusting access controls, enabling encryption at rest, or implementing additional security measures such as rotation policies or audit logging.

  3. Test and monitor: After making the necessary changes, it is important to thoroughly test the remediated secret to ensure that it is functioning as expected. Monitor the secret for any unusual activity or potential security breaches. Regularly review and update the secret settings as needed to maintain a secure environment.

​
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})
