A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

Alternative to ClamAV? (self.selfhosted)

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.

I use python professionaly. Never seen a real successful supply chain attack on libraries used by "normal" people. There was recently a supply chain attack to pytorch, that I remember, but it was solved within few hours.

It is not a real risk for non developers. It is a risk, but veeery low, miles lower than pdf.exe.

Just check this stat for ransomwares taken as an example of viruses: https://www.statista.com/statistics/701020/major-operating-systems-targeted-by-ransomware/

Windows server is ~20% of server market. Still it is there second, with in practice no GNU/linux (80% of server market). This is why people do not really worry much, the risk exists, but it is minimal for well configured system compared to competition, even where competitors are a niche and Linux machines are the main target.

On windows, an antivirus is not a bad idea... On Linux, a firewall and basic care are usually sufficient
