Prose
The Red Hat Enterprise Linux operating system must be configured so that the Network File System (NFS) is configured to use RPCSEC_GSS.
Medium Severity
When an NFS server is configured to use RPCSEC_SYS, a selected userid and groupid are used to handle requests from the remote user. The userid and groupid could mistakenly or maliciously be set incorrectly. The RPCSEC_GSS method of authentication uses certificates on the server and client systems to more securely authenticate the remote mount request.
