Securing Ubuntu

Ubuntu 7.10 actually comes with some pretty good security practices already set up for you. For example, the root account is locked and no network services are enabled by default. If you’re planning on making your Ubuntu system publicly accessible, here are some things to consider before you forward a port or public IP address.

  • If a bad guy has physical access to your system, it’s not your system anymore.
    One could boot from a CD, Floppy or USB and replace your trusted programs with altered ones.
  • If a bad guy can persuade you to run his program on your system, it’s not your system anymore.
