Computer Security Is Very Important

GENERAL INFORMATION ABOUT COMPUTER SECURITY

Computer Security is for everyone. It is VERY important to have a good computer security policy. Not only making backups and things like that. You should also watch so not the "wrong" person get access to you data that you store on your computers. I have gather some information to secure up UN*X boxes (mostly) that are connected on LAN's (Local Area Network) and WAN's (World Area Network) and some TCP/IP related problem. It is VERY important if your computer is connected directly to Internet to keep a secure computer.

UN*X and TCP/IP security

If You want to learn about UN*X security and Network security you should learn about the network protocol that are used on UN*X boxes and on internet. It's called TCP/IP (ps-format). And you should alsolearn a bit about UN*X commands and UN*X networking.This is very useful EVEN if You think you know almost everything about UN*X commands and UN*X networking.

Now to the fun part. If you want to check if your UN*X system is in any danger You might test to make a break in. I don't encourage anyone to break into any one else's computer system. If you don't have any system to test on that you are sure that you are allowed to do it on. DON'T do it. I don't encourage anyone to break into sites that they don't have legal access to. If anyone does that with this information I can't be held responsible for it. Because this information is only for evolution and to help System-administrators keep the bad "hackers" out of the systems. IMHO a hacker is a person who is really good with computers and making programs and clever solutions, not a guy who tries to break in to computers that the media wants us to think about a hacker.
And also remember that in most countries it is against the law to break into a computer system if you don't have permission to do it. In some countries even that are a little fuzzy even thou you have permission.

The Department Of Defens have created some security grades for how high security a Operating System provide. The levels are as follows
D Lowest
C{1,2}
B{1,2}
A
Beyond A Highest

You can read more about the different security levels in the Orange book that DOD is publishing.

Now I don't have time to write down more interesting information. But i have a small collection of interesting files that you might want to take a look at my collection of interesting files without descriptions
