authentication, including when a user does something using sudo

the computer starts up
/var/log/kern.log—Saves information from kernel messages, such
as warnings and errors
/var/log/syslog—Saves information from system events
/var/log/ufw.log—Saves information from the Ubuntu Firewall
/var/log/apt/history.log—Saves information about package

their own directories and may even create multiple log files within their
directories.
