    for synchronet? no... but...

    a firewall is like a condom to protect the machine/network... anti-virus is like spermicide to try to stop whatever may get by the condom...

    that's a bikini comparison... short and to the point...


    i don't know about today but some years back, someone put a winwhatever system naked on the net and it was p0wned before the updates were downloaded... might have been an XP system back then... not sure what the raw state of winwhatever is these days... it still has its holes, though...

    the general recommendation is that every machine runs a firewall to protect it from whatever may be trying to get in no matter if that is from the WAN (aka internet) or something else that got loose inside the network...

    Firewall - yes. AV - no.

    Is it mandatory or optional?

    See above.

    Generally I think it's always good to run a firewall, regardless of your OS. An anti-virus program can be good to use too, even to detect and eliminate viruses for other platforms so they won't spread.

    AV no? Wouldn't you still want to at least catch viruses and prevent them from being spread to other systems?

    But I thought firewalls and anti-virus wasn’t important because no one can hack into Linux or get a virus for it either.

    A firewall and anti-virus are always optional no matter what OS you're running. For security reasons, I'd use all tools available to increase security.

    Linux viruses are less likely or prevalent but they do exist. For my un*x (linux) systems I use fprot, I believe it is still free for Linux Home Use http://www.f-prot.com/download/home_user/download_fplinux.html

    As for Linux Firewalls, IIRC, unless a service port is open and has a service listening on it, the connections are refused, and the router I use has a built in firewall used with it's port forwarding ...

    True, but being able to throttle, block and or log the open ports is nice.
    If you're running NAT/port forwarding on the router, it's still good to
    block RFC1918 spoofing and other methods for getting arounf NAT.

    No system is invulnerable. I'm sure there are vulnerabilities in Linux systems. People just tend to fovus mainly on software people use the most, such as Windows etc. I don't think people have focused on Linux attacks as much as Windows.

    And as I said, you also wouldn't want viruses to spread to other systems. Even if you run a Linux server, it would be a good idea to be able to stop Windows viruses from spreading to Windows users.

    Of course, Linux has its own firewall - iptables. :) I don't normally use it on end hosts for the reason you said above, but I do use it on machines acting as routers to keep out unwanted probes and bots. On the tunnel router that provides IPv4 to the BBSs, I filter out SIP traffic, because I do have some internal SIP devices, and SIP probes are constant. On another network, I've had to block a number of ports from probes using iptables.

    FWIW, cvs.synchro.net, my primary Linux server runs completely in a DMZ with a static public IPv4 address, so no firewall/filtering and no NAT. Been running that way since 1995 and only had a problem once when my RedHat5 FTP server (ncftpd?) was pwned. And no anti-virus software (though my Windows server's AV will find and quarantine any infected uploads automatically). <shrug>

    But I thought firewalls and anti-virus wasn't important because no one can hack into Linux or get a virus for it either.

    then you've been lied to... hell, my perimeter firewall is a linux system and every one of my internal machines, workstations or servers, all run a firewall on them... antivirus is another thing, though... there are virii for linux but they are not as prevelent as those for winwhatever or macos with their users that click on most anything... that's not to say that there aren't linux users that do the same, though...

    another thing is that much of today's stuff better falls under malware instead of virus... why? because it takes a user to kick it off and let it loose by clicking on something they think is something else due to the social engineering around the link...

    for example: i see spam about something to do with my bank account and i can immediately reject it because i have no bank account anywhere so that social engineering scare tactic won't/can't work on me... if i clicked on it, it is probably a phishing page trying to get my credentials or it could be part of a malware infection chain of sites or it could be both...

    Several years ago I tried to explain that on a forum that was mainly composed of linux users. They were saying things like, "who cares about Windows

    Well said. I haven't followed them lately, but there used to be a contest called Pwn it to own it, and this security company would invite hackers to demonstrate how fast a laptop can be compromised. The same model laptop
    would be used for each day or level of competition, set up with Windows and various distros of linux respectively. At the OS level, both Windows and
    linux boxes were pretty solid if patches were up to date. Third party software, especially when left unpatched, was the main method for killing or crashing services on either OS to gain a foot hold on the pc.
