Add nosuid Option to /var/log
An XCCDF Rule
Description
The nosuid
mount option can be used to prevent
execution of setuid programs in /var/log
. The SUID and SGID permissions
should not be required in directories containing log files.
Add the nosuid
option to the list of
Options
in the systemd.mount
unit that
controls mounting of
/var/log
.
Rationale
The presence of SUID and SGID executables should be tightly controlled. Users should not be able to execute SUID or SGID binaries from partitions designated for log files.
