when its installed needs locking down HARD.

so true, de"fault knoppix is definately not something you want to go on the internet with, not only you have to lock down services, try to upgrade the kernel(it's bugged) and remove a bunch of useless (suid) files too, when you don' with that, it starts to get reasonably to work with it, although you're not finished yet: you may want to secure/upgrade specific services too.

really interesting topic

linux can protect you from windows malware (worm, virus, trojan, windows applications exploit, windows rootkits)

but there is a lot of linux rootkits around
a rootkit scan an ip adress or a range ip looking for some defined open ports (associated with known process security whole)
it logs the scan result in a file and ask you if you want to try to exploit the security wholes on the target comp

there are some root kits you can add your own exploit

so put a linux workstation directly on the internet is not so secure as it seems

my mandrake 8.1 webserver installed behind a secured debianbox was hacked two times in a year

actually, what you describe is a worm, a rootkit is a set of utilities, typically kernel level enhancements that try to hide anomalous activity. for instance, hide network connections as seen wirh netstat, processes as seen by ps, it sometimes adds a icmp backdoor etc.

@xaoz
thanks for the help

as you can find over 70 000 windows malwares
as you can find up to 70 linux malwares, linux is a natural protection

the actuals most knows rootkit are like you have defined
but this is just a kind of rootkit

a rootkit is a tool which will give a root access on a target comp
as there many ways to try to do it, every tools attempting to do it are called rootkit

when i see debian router box's firewall log, i can see the attacks

it's very interesting too
