Vulnerability Discussion
Placing "/var/log" in its own partition enables better separation between log files and other files in "/var/".
Check
Verify that a separate file system/partition has been created for "/var/log" with the following command:
$ mount | grep ' /var/log '
/dev/mapper/luks-e0d162f5-fad8-463e-8e39-6bd09e672961 on /var/log type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)
If a separate entry for "/var/log" is not in use, this is a finding.
Fix
Migrate the "/var/log" path onto a separate file system.
