I'm on a variant of Ubuntu 10.04 and I want to configure my firewall in a way that it couldn't be attacked by non-sophisticated attacks, I have also installed Gufw...but I'm not sure if it's reasonable enough to just enable ufw, if you know a set of rules that fits the best for open environments(university with a lot of hackers!) like where I am, please let me know.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
http://gufw.tuxfamily.org/ and/or https://help.ubuntu.com/community/Gufw I would take into account a simple firewall "rule" of my own: "Allow" only the services you must have and "deny" everything else;) More useful info: http://www.techotopia.com/index.php/Using_gufw_and_ufw_to_Configure_an_Ubuntu_11.04_Firewall Good luck!
