Set "mesg n" as Default for All Users

FaibleNiveau 1Automatiséesolaris

Description

The "mesg n" command blocks attempts to use the write or talk commands to contact users at their terminals, but has the side effect of slightly strengthening permissions on the user's tty device. Since write and talk are no longer widely used at most sites, the incremental security increase is worth the loss of functionality. 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

r=compliant; grep -q "^mesg n" /etc/.login 2>/dev/null || r="mesg n missing in /etc/.login"; grep -q "^mesg n" /etc/profile 2>/dev/null || r="mesg n missing in /etc/profile"; echo "$r"

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Perform the following to implement the recommended state: # cd /etc # for file in profile .login ; do if [ "`grep mesg $file`" ]; then awk '$1 == "mesg" { $2 = "n" } { print }' $file > $file.CIS mv $file.CIS $file else echo mesg n >> $file fi done
