Exclamation Security software against Virus, Spyware and Spam ??


Attention

Spam - Virus - Spyware

I've heard that it isn't possible for virus to enter linux, but some other of my friends tells me that it can be done.. I don't know what to believe..
But if I should get protected against Viruses which software is the best then ??

And what about Spam and Spyware ??
And firewall ??

If you can't break into i linux machine as some says, than I really don't need any of these protections right ??


help me, I don't know what to believe..

Virus: These are possible in Linux, and some *have* been written. But given the inherent security of the Linux kernel, and the hetrogenous nature of Linux distros (we're all the same, yet *different*), none has ever taken hole in "the wild". As I understand it, there are not even true Linux virus-checkers. The anti-virus programs you can find for Linux really just check your incoming email for Windows viruses, so you don't inadvertantly pass them on to Windows users....

Spam: If you get email, you get spam. There are some good tools available, like "spamassassin", to help you manage the problem.

Spyware: Like viruses, it's possible, but also like viruses, the very nature of Linux works against it.

In any case, having a good firewall is always a safe computing practice. Without one a poorly-configured Linux box would be vulnerable to being rootkitted. Most firewalls that I am aware of run on top of iptables, the basic Linux firewall. So if you feel guru-ish, just manage your iptables.

thanks..

I think I'll reach for Spam-protection only

I don't care a shit if windows users is being affected from my linux-machine. But if My machine is getting full of these tings, I may remove'em soon or later. but not before.

Spyware ?? Don't care if it can't affect me..


In the end.. my opinion after help from others, my understanding of it is that a linuxmachine can't be affected seriously anyhow, and if this is true... No protection at all is needed.
The only thing is that my Email may be full of spam, which can be annoying enough. but what the heck.. A Spam-killer is all I need then.

If you can't manipulate with the system without root privileges,. then I can't be "hacked" in any way from outside right ??

It's hard but cool to think that all I need is Spam-protection against annoying spams in my inbox..


If I'm wrong, please correct me..


Thanks pal..

True, as far as it goes. There *are* sniffers and other programs that can help crackers gain access to your system from outside, if you are not behind a firewall. Once they gain access, they can install a "rootkit", using known vulnerabilities in the system (a good reason to keep up-to-date on security patches ), and have root access to your system.

If you follow good, tight security practices, you can be pretty safe even without a firewall, but IMHO, why take the chance?

I run a firewall and spamassassin on my system, and keep up-to-date with security patches. I haven't had any problems yet.
