The Syslog protocol was initially written by Eric Allman.

Syslog can help with centralized management, security monitoring, compliance, and efficiency, making it good practice for many organizations.

Syslogs help in achieveing complicance requirements too for the companies as they mandate retention and collection of logs.

Here will show some commands that will help in doing changes to rsyslog which will enable us to send the sudo logs to syslog.

Currently no sudo logs are present in syslog ->

We will be doing our changes in /etc/rsyslog.d ->

1. Create a file sudo.conf

2. Open the file vi sudo.conf

3. Add the code snippet ->
   if $programname == 'sudo' then /var/log/syslog & stop

4. Restart rsyslog -> sudo systemctl restart rsyslog

5. Now run -> grep sudo /var/log/syslog

U might need to do all the above commands as root.

Now when we run this command ->
grep sudo /var/log/syslog

Above you can see sudo logs inside the syslog.

I tried on Debian. You may well try on other linux flavors. 🍻🍺
