What is the recommended storage strategy for Operator Keys in CyberArk?

The recommended storage strategy for Operator Keys in CyberArk is to copy only the Recovery Public Key to the server. This approach ensures that sensitive cryptographic keys, especially those used for recovery purposes, are not exposed unnecessarily. By restricting the storage of keys to only the Recovery Public Key, you minimize the risk of potential leaks or unauthorized access while still allowing for necessary recovery operations.

This method bolsters the security posture of the environment since it limits the number of places where keys are stored, reducing the attack surface. In situations where keys are needed for operational tasks, securely managing their storage and access becomes critical.

Options that involve storing all keys on the server, keeping all keys in a file, or storing them in the cloud unnecessarily complicate key management and increase vulnerability to attacks. These alternatives could lead to potential breaches or misuse, which is contrary to best practices in cybersecurity.
