| Description |
|---|
| The fingerd daemon provides the server function for the finger command. This allows users to view real-time pertinent user login information on other remote systems. This service should be disabled as it may provide an attacker with a valid user list to target. |
| ℹ️ Check |
|---|
| From the command prompt, execute the following command: # grep "^finger[[:blank:]]" /etc/inetd.conf If there is any output from the command, this is a finding. |
| ✔️ Fix |
|---|
| In "/etc/inetd.conf", comment out the "finger" entry by running command: # chsubserver -r inetd -C /etc/inetd.conf -d -v 'finger' -p 'tcp' Restart inetd: # refresh -s inetd |
