  • If you think ClamAV on your mom's laptop on Starbucks WiFi is doing anything useful, but you think fail2 ban isn't - you're naive.

    On phishing - you've got another great example. ublock origin or any other decent adblocker will do WAAAAY more to help than ClamAV.

  • Ideally you keep your configs in a git repo (like github). You know what's modified because you're the one who modified them. If you modify them - put that config file in the git repo.

    As for "put down" I just meant copied to the system (from github) by your automation (like ansible)

    https://docs.ansible.com/ansible/latest/getting_started/index.html

  • That, and:

    • put down config files that were modified
    • enable/start services that were installed
    • modify the firewall to open necessary ports

    Basically: put everything back as it was right before the ransomware encrypted your system on you.

    Then of course - fix what you did wrong that got you compromised. ;-)

  • No, most desktops behind a NAT probably dont need fail2ban (though it wouldn't hurt).

    Everyone's security profile/needs are different.

    The point is that list does a hell of a lot more useful than ClamAV

  • You'd be better served learning how to setup and use:

    • backups (and test them)
    • automate your reinstall (see ansible)
    • firewalld (RHEL/Fedora) or ufw (Ubuntu)
    • fail2ban
    • SELinux (RHEL/Fedora) or AppArmor (Ubuntu)
    • disable SSH via password, use keys only
    • adblocker (like ublock origin) - credit to whale@lemm.ee for the idea below
  • Hi - been a sysadmin for 19 years and I can tell you why: software that 'requires' Ubuntu. I work at a University and all of our required software runs on either RHEL or Ubuntu. I would LOVE to move everything to RHEL and rid my life of Canonical shenanigans, but we have software that just won't run (in any sane form) on RHEL. The researchers especially love Ubuntu because much of the software used in the LLM/AI explosion is generally released with Ubuntu packages, or install instructions based on Ubuntu package dependencies.

    tl;dr - it's not the sysadmin choosing, it's the developer choosing.
