[TriLUG] Basic Security Question

[Lisa C. Boyd]

Three years ago (yeah - I know - an eternity in software time), I went to a 
seminar/conference about Linux. The speaker was talking about how Linux 
installs left a lot of open doors that are major security risks. Doors that 
have to be closed by the user and that most student users never realize 
that they need to close those doors. This was at a time when there were a 
lot of problems on the network due to students not configuring their 
computers correctly.

So - is this true for installations nowadays? And if so, ya'll will help me 
Saturday close all those doors right? ;)
