    Putting extra security layers on Ubuntu

    Hello, everyone. I've installed Ubuntu 2 months ago and I really like it. But, I come from Windows and I still feel I need to secure my system. I have a lot of roommates and I really don't trust them. We share the same wireless network. How can I make my Ubuntu more secure? I know that Linux is very secure but how do I put extra security layers so that my computer is virtually uncrackable? Thank you for your help.

    Make sure you set an administrative password on your router, not just a password to connect. Turn off uPnP. Stick to the guide that was just posted and you should be fine ^^

    Since you do not trust your roommates and you are sharing the same wireless network (i.e. in the same subnet), you may worry about the ARP Spoofing attack.

    If your room mates have physical access to your computer, then all bets are off. So if you are truly paranoid, get a lockable steel cabinet.
