Description
Unauthorized disclosure of the contents of the /var/log/lastlog file can reveal system data to attackers, thus compromising its confidentiality.
ℹ️ Check
Verify the "lastlog" command has a mode of "0750" or less permissive with the following command:
$ sudo stat -c "%a %n" /usr/bin/lastlog
750 /usr/bin/lastlog
If the "lastlog" command has a mode more permissive than "0750", this is a finding.
✔️ Fix
Configure the mode of the "lastlog" command for OL 8 to "0750" with the following command:
$ sudo chmod 0750 /usr/bin/lastlog
