You can easily disable NFS, which is a commonly used for sharing data and files between machines. However, its use opens many potential security holes. If NFS is not needed, improve the security by removing and disabling NFS. Open a command-line terminal (select Applications > Accessories > Terminal), and then type:
# chkconfig nfslock off
# chkconfig rpcgssd off
# chkconfig rpcidmapd off
# chkconfig portmap off
# chkconfig nfs off
Delete nfs-utils and portmap packages using the yum command:
# yum remove portmap nfs-utils
