Which NAS protocol integrates with Windows Active Directory to provide and manage file security?

NFS (Network File System) is primarily used in Unix/Linux environments and requires additional configuration, such as ID mapping or an LDAP-based directory service like AD, for security integration in a Windows-centric Active Directory.

CIFS, or Common Internet File System, is a specific dialect of the Server Message Block (SMB) protocol. It is specifically designed to work within Windows environments and seamlessly integrates with Active Directory for user authentication, authorization, and the enforcement of file and folder level security permissions.

SSH (Secure Shell) is a protocol for secure remote command execution and file transfer, not a network attached storage (NAS) protocol for providing shared file system access and security.

NDMP (Network Data Management Protocol) is used for network-based backup of NAS devices and is not a client-facing protocol for file sharing or security management.
