What protocol is used for external recordings to the Vault?

The correct protocol used for external recordings to the Vault is SMB 3.0.

SMB (Server Message Block) is a network file sharing protocol that allows applications to read and write to files and request services from server programs. The use of SMB 3.0 specifically ensures enhanced security features and performance improvements over its earlier versions. Given that Vault operations may involve transferring sensitive information securely, SMB 3.0 facilitates this through its built-in encryption and integrity checks.

This makes SMB 3.0 a fitting choice for operations involving the CyberArk Vault, as preserving the confidentiality and integrity of sensitive data is paramount in cybersecurity practices. Other protocols might not provide the same level of security or are not typically used for interactions with Vault. For instance, while FTP Secure does include encryption, it is less commonly utilized for direct external recordings compared to SMB 3.0 in this context.
