cyberstrikeus 2.1.7 Ensure NFS is not installed (Automated)
Description
The Network File System (NFS) is one of the first and most widely distributed file systems in the UNIX environment. It provides the ability for systems to mount file systems of other servers through the network.
Rationale
If the system does not export NFS shares or act as an NFS client, it is recommended that these services be removed to reduce the remote attack surface.
Audit Procedure
Command Line
Run the following command to verify nfs is not installed:
dpkg -s nfs-kernel-server | grep -E '(Status:|not installed)'
Expected Result
dpkg-query: package 'nfs-kernel-server' is not installed and no information is available
Remediation
Command Line
Run the following command to remove nfs:
apt purge nfs-kernel-server
Default Value
nfs-kernel-server is not installed on minimal server installations.
