What is a File Key in the context of CyberArk?

In the context of CyberArk, a File Key is a unique symmetric key that is generated specifically for each file. This unique key is essential because it allows for the secure encryption and decryption of sensitive data stored in those files. Since symmetric keys use the same key for both encryption and decryption, it is important that each key remains confidential and unique to its corresponding file to ensure a high level of security. This method of using individual keys enhances the overall protection of sensitive information within CyberArk's privileged access security framework.

The other options do not accurately describe the role of a File Key within CyberArk. Public keys, for instance, are typically used in asymmetric encryption scenarios rather than being utilized for individual files in this manner. Similarly, while keys that encrypt communication between servers serve a critical function in secure communications, they do not pertain to the unique encryption of individual files. Lastly, backup keys for restoring credentials are different from File Keys, as they serve a specific purpose related to credential recovery rather than file encryption.
