Ok im abit of a newbie to security in general yet alone Linux security so i have been doing alot of googleing( And a few other search engines ). Ok i have a clean install of redhat 9 (as it came with a book about linux) and was looking for some general pointers on making it more secure. Like i said ive been searching the net for this stuff so i dont want extensive essays about things that have been written about before, I just want some quick general pointers on how to secure the machine (its is actully a stand alone machine but i want to play about with security as if it was on a network if possible running some common services to try and broaden my somewhat lacking knowledge on the subject). I have already looked into ip tables (i decided on this over ip chains however i have yet to get it working but still i try). Anyway thanks for any input on this also any good sources related to *nix security i can browse would be appreciated
