What this card says
What it is
NFS (Network File System, ports 111/2049) shares Linux folders over the network. Enumeration lists the shared folders (exports).
The risk
A world-readable export, or no_root_squash (remote root = local root), is very dangerous.
Common mistake
Mounting a no_root_squash share from a real server “to test”.
Fix: limit exports to known hosts, use root_squash, read-only where possible. Lab or scope only.
