| Description | ||||
| Unauthorized group ownership of the /etc/hosts file can lead to the ability for a malicious actor to redirect traffic to servers of their choice. It is also possible to use the /etc/hosts file to block detection by security software by blocking the traffic to all the download or update servers of well-known security vendors. | ||||

Check Text (C-245558r991589_chk)
Check the group ownership of /etc/hosts using command:
# ls -al /etc/hosts
The above command should yield the following output:
-rw-r----- 1 root system 993 Mar 11 07:04 /etc/hosts
If the file is not group-owned by system, this is a finding.
Fix Text (F-48792r818796_fix)
Change the group ownership of the file to system using command:
# chgrp system /etc/hosts
