Discussion

Setting the most restrictive default permissions ensures that when new accounts are created they do not have unnecessary access.

Check Content

Check for the configured "umask" value in "login.defs" with the following command:

# grep UMASK /etc/login.defs

If the default "umask" is not "077", this a finding.

Note: If the default umask is "000" or allows for the creation of world-writable files this becomes a Severity Code I finding.

Fix Text

To configure the correct UMASK setting run the following command:

# sed -i "/^[^#]*UMASK/ c\UMASK 077" /etc/login.defs
