TL;DR - What are you running as a means of “antivirus” on Linux servers?

I have a few small Debian 12 servers running my services and would like to enhance my security posture. Some services are exposed to the internet and I’ve done quite a few things to protect the services and the hosts. When it comes to “antivirus”, I was looking at ClamAV as it seemed to be the most recommended. However, when I read the documentation, it stated that the recommended RAM was at least 2-4 gigs. Some of my servers have more power than other but some do not meet this requirement. The lower powered hosts are rpi3s and some Lenovo tinys.

When I searched for alternatives, I came across rkhunter and chrootkit, but they seem to no longer be maintained as their latest release was several years ago.

If possible, I’d like to run the same software across all my servers for simplicity and uniformity.

If you have a similar setup, what are you running? Any other recommendations?

P.S. if you are of the mindset that Linux doesn’t need this kind of protection then fine, that’s your belief, not mine. So please just skip this post.

There are still no viruses for Linux ... because it's not possible.

Here is just one example that proves your assertion wrong.

So if I'm reading this correct the vulnerability was patched before the worm got programmed and it peaked at 2000 machines infected when it targeted apache servers running openssl, which back in 2002 was basically any encrypted website.

Don't know how an AV would have helped there.

Simply refuting the BS claim that it's impossible for there to be a Linux virus.

This one existed, therefore the claim is false.

[-] mathemachristian@lemm.ee 2 points 1 year ago

The claim was within the context of AV software, not a general one.

Apache and OpenSSL must be enabled and OpenSSL version must be 0.96d or older.

Right. Completely proven wrong.
