Securing Slackware 8.1


Hey everyone,

Can somebody point me to a good, recent guide on securing my Slackware 8.1 box?

I use this machine as a gateway/firewall/web server/ftp server. So there are obviouslly many security issues with a machine so open.

I want to set up a mail server as well, and installed UW IMAP but ran into problems with error 550 - relaying denied. I think I have decided that before I go any further trying to enable my mail server I want to really audit my system and ensure it is secure as possible. The last thing I want is to become a mass-mailer for somebody and get black listed.

My problem is that most of the guides on securing are centered around RPM based distro's - and the only Slackware specific guides I can find are very old.

Any links you could provide, or even advice on security issues I should be concerned with would be a huge help.

Thanks a lot for your time

I know I posted this a while ago, but I thought I was subscribed to the thread and when I got no notifications I figured noone responded...

Anyway, thanks for the link Nautilus, although that paper is dated from 1998. Although it seems to cover a lot of the basics, do you know of anything more recent (e.g. at least referring to 2.4 kernel) that is targetted toward Slackware?

Thanks again

Tekime, not that you should consider this gospel but I have looked before and could not find anything recent on security targeted specifically towards Slackware.

OTOH there are a couple of dead-tree books out there on security of *nix systems not targeted towards any particular distro that are reasonably good. I don't know the titles off the top of my head but if you like when I get into work tomorrow I can post them.

http://www.c2i2.com/~dentonj/system-hardening

Has some detailed info on securing Slackware.

This is aimed at 8.0 but much of it is still relavent to 8.1

You could also check out www.sastk.org
Still only working on 8.0 but if you look through the scripts you should get a good idea of what it does.

Thanks for the links mRgOBLIN, I'll look into both of those. I actually ran across SAStk not too long ago, but I wasn't sure whether it would be of any use for 8.1. I also found THIS .DOC which again is aimed at 8.0, but is somewhat lengthy.

Mephisto, if you could post a couple titles that would be appreciated. It's about time I got a good generel *nix book, the only real reference material I have is a Debian 2.1 book by Sams.

Thanks again

Tekime if you want to secure your box "a bit" here is a firewall script
that Aussie (moderator of Hardware section) gave to all of us:
ftp://ftp.p-two.net/pub/rc.firewall

I've spent quite a bit of time working my rc.firewall, but I will certainly have a look. Thanks
