Execute the lynis --check-all command to scan for problems. Just keep pressing ENTER until the scan is over; the results are saved in the /var/log/lynis.log file. Read through this to get a picture of the security of your Linux system.

Type sudo apt-get install lynis to install this on Linux Mint 17 or Ubuntu 14.10. This will help if you are setting up a secure Ubuntu server machine and you need an auditing tool to check your configuration.
