Ensure NFS server services are not in use

MoyenneNiveau 1Automatiséeaix

Description

De-install NFS server if the server does not act as an NFS server to remote clients. An expected exception is a system configured as a NIM server. NFS is frequently exploited to gain unauthorized access to file and directories. Unless the server needs to act as an NFS server or client, the filesets should be de-installed. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

Méthode de vérification

Méthode d'audit: Commande shell

shell

command -v lslpp >/dev/null 2>&1 || exit 1; lslpp -L >/dev/null 2>&1 || exit 1; out=$( { lslpp -L | grep -i 'bos.net.nfs.server' ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Ensure that there are no current NFS exports: cat /etc/exports The above command should yield no output. Or the file should not exist. De-install the NFS sever software: installp -u bos.net.nfs.server If there was an empty /etc/exports file, remove it: rm /etc/exports
