What is 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?

The CyberArk Vault Synchronizer is designed to automate the process of making Vault secrets available in Conjur. For each synchronized Safe, the Synchronizer automatically generates a Conjur policy that includes a consumers group (role). This group is granted read and execute permissions on all variables (secrets) synchronized from that Safe. By adding a Conjur host as a member of this consumers group, the host inherits these permissions. The Synchronizer ensures this group's access is perpetually aligned with the Safe's contents, automatically reflecting any additions or removals of accounts without requiring any manual policy changes. This is the intended and most maintenance-free integration pattern.

A. Writing a custom script introduces a new component to develop, manage, and maintain, which is the opposite of a "maintenance-free" solution compared to the built-in Synchronizer functionality.

B. YAML syntax like anchors and wildcards simplifies policy file creation but does not create a dynamic link to the Vault; the policy would still require manual updates and reloading as Safe contents change.

D. The PVWA is used to manage Vault-native entities (users, applications) as Safe members. A Conjur host ID is not a Vault entity and cannot be directly added as a Safe member through the PVWA.

1. CyberArk Conjur Documentation - How the Synchronizer works:

"For each synchronized Safe

the Synchronizer creates a Conjur policy that defines Conjur resources and permissions. This includes: ... A consumers group with read and execute permissions on all variables in the Safe." This section explicitly details the creation and purpose of the consumers group.

2. CyberArk Conjur Documentation - Delegate permissions on a synchronized Safe:

"To grant a role

such as a host

permissions on all of the secrets in a synchronized Safe

add the role as a member of the Safe's consumers group. For example

to grant the my-app layer permissions on the db-passwords Safe

add the following grant statement to a policy file..." This page provides the exact procedure described in the correct answer

confirming it as the standard

maintenance-free method.
