Network File System security

The Network File System (NFS) is a widely available technology that allows data to be shared between various hosts on a network.

NFS also supports the use of Kerberos 5 authentication in addition to DES. Kerberos 5 security is provided under a protocol mechanism called RPCSEC_GSS.

In addition to the standard UNIX® authentication system, NFS provides a means to authenticate users and machines in networks on a message-by-message basis. This additional authentication system uses Data Encryption Standard (DES) encryption and public key cryptography.

NFS also supports the use of Kerberos 5 authentication in addition to DES. Kerberos 5 security is provided under a protocol mechanism called RPCSEC_GSS. For a description of how to administer and use Kerberos authentication with NFS, see the NFS Administration Guide.
