Ensure NFS client mounts are disabled in /etc/filesystems
SrednjaNivo 1Automatskaaix
Opis
Disable automated mount of remote NFS shares. NFS is frequently exploited to gain unauthorized access to files and directories. Automated and/or pre-defined mounts should not exist. AIX does not allow the kernel service that enables NFS mounts to be disabled. Audit: no stanza in /etc/filesystems may use vfs = nfs.
