Description
The pop3 service provides a pop3 server. It supports the pop3 remote mail access protocol. It works with sendmail and bellmail. This service should be disabled if it is not required to prevent attacks.
ℹ️ Check
From the command prompt, execute the following command: # grep "^pop3[[:blank:]]" /etc/inetd.conf If there is any output from the command, this is a finding.
✔️ Fix
In "/etc/inetd.conf", comment out the "pop3" entry by running command: # chsubserver -r inetd -C /etc/inetd.conf -d -v 'pop3' -p 'tcp' Restart inetd: # refresh -s inetd
