Check the ownership of /etc/hosts using command: # ls -al /etc/hosts The above command should yield the following output: -rw-r----- 1 root root system 993 Mar 11 07:04 /etc/hosts If the file is not owned by root, this is a finding.
Unauthorized ownership of the /etc/hosts file can lead to the ability for a malicious actor to redirect traffic to servers of their choice.
