Security Commands

[Ivan]

Hello guys, I am searching for all Linux commands realted in security, if someone can help me i will be very thankful

Hi!

Could you say what distro you use, and what kind of security you are intested in?

The question you're asking could require a whole book, so please narrow it down a little. In the meantime, linuxsecurity.com is always good

Good luck

I am using linux Redhat 8, and I have a research on all security commands like nmap and other commands, i don't know a lot about them, and all i need at first is a list containing the security related commands and i can find how each command works and what is each command in the man pages

There aren't any security commands in Linux. There does exist various binary programs and scripts which can be used to make a system more secure. I don't believe there is any standard as to which "security" programs are included with each distribution. There are a variety of programs available and they are sometimes categorized by the type of activity that they do, such as port scanners, email filters, etc. Making a system secure involves much more than can be done with just a couple of security commands. The only commands that I would say are part of any standard are chmod (file permissions) and passwd (user passwords). Also, there are a variety of files located in the /etc directory that have to do with security. Also, each server style program has it's own configuration file for setting up options to make them more secure such as apache, sendmail, etc. You've got quite a lot of research ahead of you. Start out by googling.

As far as nmap, just type

man nmap

in a console.
Also, the html docs are here: http://www.insecure.org/nmap/

Try googling the rest and see what you can dig up.
