SECRET-SEN Exam Dumps : CyberArk Sentry Secrets Manager

The cause of the issue is that the host does not have access to the credential. This can happen if the host does not have the correct permissions or if the credential is not properly configured in the Vault Conjur Synchronizer.

The Vault Conjur Synchronizer is a tool that enables the integration between CyberArk Vault and Conjur Secrets Manager Enterprise. The Synchronizer synchronizes secrets that are stored and managed in the CyberArk Vault with Conjur Enterprise, and allows them to be used via Conjur clients, APIs, and SDKs. The Synchronizer creates and updates Conjur policies and variables based on the Vault accounts and safes, and assigns permissions to Conjur hosts based on the Vault allowed machines.

To fix this issue, the host needs to have the permission to access the credential in Conjur. This can be done by adding the host to the allowed machines list of the Vault account that corresponds to the credential, and synchronizing the changes with Conjur. Alternatively, the host can be granted the permission to access the credential in Conjur by modifying the Conjur policy that corresponds to the Vault safe that contains the credential, and loading the policy to Conjur. However, this may cause conflicts or inconsistencies with the Synchronizer, and is not recommended.

For more information, see the CyberArk Vault Synchronizer docs1 and the Synchronizer Troubleshooting guide2.

 Secrets Provider and Secretless are two solutions that can minimize the Kubernetes application code changes required to adopt Conjur for secrets access. Secrets Provider is a Kubernetes Job or Deployment that runs as an init container or application container alongside the application pod. It retrieves secrets from Conjur and writes them to one or more files in a shared, mounted volume. The application can then consume the secrets from the files without any code changes, as reading local files is a common and platform-agnostic method. Secretless is a sidecar proxy that runs as a separate container in the same pod as the application. It intercepts the application’s requests to protected resources, such as databases or web services, and injects the secrets from Conjur into the requests. The application does not need to handle any secrets in its code, as Secretless handles the authentication and authorization for it. References: CyberArk Secrets Provider for Kubernetes, Secretless Broker

 The most maintenance-free way to ensure a Conjur host’s access reflects any changes made to accounts in a safe in the CyberArk vault is to grant the consumers group/role created by the Synchronizer for the Safe to the host. This means that the host will inherit the read and execute permissions on all the secrets in the Safe from the consumers group/role, and will automatically get access to any new or updated secrets in the Safe without requiring any manual intervention or policy changes. The consumers group/role is created by the Vault Conjur Synchronizer, which is a service that synchronizes secrets between the CyberArk vault and Conjur. The Synchronizer creates a policy branch for each Safe in Conjur, and assigns the consumers group/role to have read and execute permissions on all the secrets in the Safe. The Synchronizer also creates a delegation policy for each Safe, which allows the Safe admins to grant permissions to other users, hosts, groups, or layers12.

The other options are not the most maintenance-free ways to ensure a Conjur host’s access reflects any changes made to accounts in a safe in the CyberArk vault. Writing an automation script to update and load the host’s policy using PATCH/update may work, but it requires additional effort and maintenance to ensure the script is always running and up to date with the changes in the Safe. Using yami anchor [&] and wildcard (*) syntax to maintain its list of permission grants may simplify the policy writing, but it still requires manual editing and loading of the policy whenever a new secret is added or removed from the Safe. Using PVWA to add the Conjur host ID as a member of the Safe may not be possible or advisable, as the PVWA is designed for managing human users and not Conjur hosts, and it may not have the necessary integration or authorization to do so3. References: =
