I have a server that myself and a friend run that is using Debian Squeeze. We have a running RT, sql, and ftp environment. I noticed some errors in some basic commands such as pstree and ls.
The scope of this post is not to ask how to clean it up. Not yet anyways, I turned off the server and do not have physical access to it at the moment. What I want is to be pointed in the right directions on how to secure a server in linux. From the easy configurations to the nitty gritty. How do major suppliers protect their machines? Is it all in proprietary scripts?
Thoughts please. I am new to security but I am perfectly willing, and already am, doing research and would love any help I could get.
The problem is, like so many other things, people want instant gratification. They want the reward without the work, the cool of the Coke without the sweat that makes them hot in the first place... -iceblade^
