How to log all sudo commands

Sometimes it’s necessary to log all the sudo commands run in your environment.

Let”s see how to achieve this.

• • Edit the sudoers file by running visudo
    

    visudo

  • Add the below line to the Defaults section
    

    Defaults logfile=/var/log/sudo

• Now all the commands from a sudo user will be logged in /var/log/sudo file.
  

  [[email protected] ~]# cat /var/log/sudo
  Jan 11 09:40:49 : user1 : TTY=pts/0 ; PWD=/home/user1 ; USER=root ;
  COMMAND=/bin/su -
  Jan 11 09:41:56 : user1 : TTY=pts/0 ; PWD=/home/user1 ; USER=root ;
  COMMAND=/bin/ls /var/www/html
  Jan 11 09:42:08 : user1 : TTY=pts/0 ; PWD=/home/user1 ; USER=root ;
  COMMAND=/bin/cat /etc/passwd
  Jan 11 09:42:47 : user1 : TTY=pts/0 ; PWD=/home/user1 ; USER=root ;
  COMMAND=/bin/su -
