I've been exploring the security of Linux as an operating system, and while it does have some impressive security features like Firejail, SELinux, and AppArmor, I've noticed that the level of security largely depends on user practices. For instance, using trusted repositories instead of random downloads is crucial, as is minimizing the use of sudo/root access. Yet, there are still potential threats hiding in trusted applications, such as browser extensions or Steam games. Given that malware detection programs like ClamAV and Kaspersky's Linux Malware Scanner are available, I wonder if we really need an antivirus for Linux, or if there are better ways to manage these risks. What do you all think?

In an enterprise setting, you can implement security measures like SIEM products on Linux, and some companies use tools like Crowdstrike. But for personal use, if you're sticking to package managers and trusted sources, you shouldn’t worry too much.
ClamAV is the go-to for Linux antivirus, but it's mostly used to catch malware that slips in from Windows, especially on dual-boot systems. People are usually safer avoiding formats from big companies like Adobe or Microsoft, and keeping an eye out for common scams like malvertising and phishing emails. Just stay vigilant, update your system regularly, and avoid clicking on unknown links, and you should be fine.
Ultimately, security really depends on the user's choices. Linux has a lot of built-in security features, but if users aren't careful about where they download from or the software they install, they expose themselves to risks. The responsibility is on the user to make informed decisions.
I don't think Linux needs an antivirus. Many security features already exist, and if you're cautious about what you download and stay away from sketchy repositories, you're likely fine. Even major security breaches often come from user errors rather than the OS itself.
I get that, but isn't it cumbersome to run everything in a sandbox? What do you think about isolating just the browser instead?
