Good luck. You'll need it.


Any one who know articles or tutorials about these topics please give me the links .
I suggest you show you are willing contribute: go search, return and post a comprehensive list, and then ask for contribs.

OK--so we know it is homework. MY criteria for helping is that you discuss what you already know and where you have looked. Also, what is the nature of the course, training, etc.? What books read?

hi
Thanks very much for your answers
Now I have some books about "Firewall for Linux", "Linux Server security" and Cryptography book and dont have
e. Network security
b. Host Security
I have go around with Google brother but not sure which is the best choice .

Now I have some books about "Firewall for Linux", "Linux Server security" and Cryptography book and dont have
e. Network security
b. Host Security
Any basic GNU/Linux security book has chapters about host and network security AFAIK. If your target is hardcopy check out McGraw's "Hacking Linux Exposed" and O'Reilly's "Security Warrior" or check sites like SANS or SecurityFocus for more recent reviews of books. If online docs is good enough I am surprised your search-fu didn't find the LQ FAQ: Security references.

i woudl also look around on IPcop's website (a firewall)
and on RSA's website (crypto)

there is plenty of good info there,

also try wikipedia
http://en.wikipedia.org/wiki/Firewall_%28networking%29
http://en.wikipedia.org/wiki/Cryptography
http://en.wikipedia.org/wiki/Network_security
Et-cetera

Don't ask us to give you the answers. Don't ask anyone (or any web site) to do it. You're missing the point of such an exercise.

Anytime any question asks you to discuss something, the only way to do that is to understand it. That means, doing research, which btw the Internet makes it terribly easy to do.

Copying someone else's ideas "verbatim" is plagarism, and the reason why it's frowned-upon is that it's not learning. None of what you find on the Internet, or in any research library, is your "discussion" ... it is someone else's attempt to do what you're now being asked to do.

Take what various people have said and think about it. (Aye, there's the rub.) Say it in your own words. Say what you think.

"Information search." That's easy. "Analysis." Ahh, that's more work but not too much more, really.

Go ahead... try it. Lose that fear of "being wrong."

Tip: We call people who have lost that fear, and who still have something to say, "consultants," and we pay them lots of money.
