    Do you have any antivirus recomendations for Linux.

    Install all applications from your package manager.

    Don’t run things as root.

    Don’t visit sketchy websites.

    Run an ad-blocker that isn’t owned by an advertising company.

    Avast! runs on Linux.

    Personally I prefer to just avoid clicking on dodgy links. In the last 5 years I haven’t found any viruses. YMMV

    I wouldn’t recommend using anti-virus software. It usually creates a lot more overhead, plus it usually mimics existing solutions already in linux. The only viruses I have ever caught using an anti-virus software on Linux are the test viruses to see if all is working fine.

    Anyway, here’s my 20+ enterprise experience recommendations with Linux :

    • enable secure boot: will disable launching non-signed kernel modules (prevent root kits)
    • enable firewall: and only allow ports you really need.
    • SELinux: it is getting better, and it will prevent processes to access resources out of their scope. It can be problematic if you don’t know it (and it is complex to understand). But if it doesn’t hinder you, don’t touch it. I do not know AppArmor, but it is supposed to be similar.
    • disable root over ssh: or only allow ssh keys, or disable ssh altogether if you do not need it.
    • avoid using root: make sure you have a personal account set up with sudo rights to root WITH password.
    • only use trusted software: package managers like apt and rpm tend to have built in functionality to check the state and status of your installed software. Use trusted software repositories only. Often recommended by the distro maintainers. Stay away from use this script scripts unless you can read them and determine if they’re the real thing.

    Adhering to these principles will get you a long way!

      Thank you for the advice!

      Firewall on Linux is something I still don’t understand, and explanations found on Internet have always confused me. Do you happen to know some good tutorial to share? Or maybe one doesn’t need to do anything at all in distros like Ubuntu?

      Regarding ssh: you only mean incoming ssh, right?

        I don’t think you need to configure your firewall. Firewalls are usualy used to block incomming connectings. Usualy a Firewall that blocks all incomming connections is already active on your modem/router. Adding exception to the modem/router Firewall usualy happen through port forwords.

    I don’t understand why we keep telling new users that it is useless to use an antivirus on Linux. For people with computer knowledge, sure. However more widespread Linux adoption will mean more casual users will start using it. Most of them don’t have the “common sense” that is often mentioned ; these users will eventually fall for scams that tell them to run programs attached in emails or random bash scripts from the internet. The possibility is small, but it’s not zero, so why not protect against it?

      Because snake oil is not helping, or a working substitute.

      Security is a process, not a solution.

          The problem with AV s/w in my experience, is that they do not work very well, and hinder the system’s functioning, because they provide duplicate behaviour of existing solutions and compete with them directly.

          In one instance I discovered McAfee to disable write access to /etc/{passwd,shadow,group} effectively disabling a user to change their password. While SELinux will properly handle that by limiting processes, instead of creating a process that would make sure those files aren’t modified by anyone.

          People need to understand Linux comes pre-equipped with all the necessary tools and bolts to protect their systems. They just don’t all live in the same GUI, because of the real complexity involved with malware…
