| Description | ||||
| Unauthorized permissions 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. | ||||

Details
Check Text (C-245559r991589_chk)
Check the mode 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 has a mode more permissive than "0640", this is a finding.
Fix Text (F-48793r818799_fix)
Change the mode of the file to 0640 using command:
# chmod 0640 /etc/hosts
