Uncomplicated Firewall (UFW) is a user-friendly firewall management tool pre-installed on many distributions. Enabling UFW and configuring rules to allow only necessary network traffic can significantly enhance security.

Staying Updated: Regular System Updates

Regularly updating the system is crucial to patch security vulnerabilities. Linux distributions provide package managers that simplify the process of updating the operating system and installed software. Enable automatic security updates for convenience.

Antivirus on Linux: Is it necessary?

While Linux is less susceptible to viruses than Windows, antivirus software can still provide an additional layer of protection. ClamAV is a popular open-source antivirus solution for Linux. Consider using it for scanning downloaded files and suspicious attachments.

Beware of Phishing and Malicious Websites

Exercise caution when browsing the internet and downloading files. Phishing attacks and malicious websites can target any operating system. Employ a reputable ad blocker and be wary of suspicious links and downloads.

Game Compatibility: Proton, Wine, and Beyond

Proton and Wine are compatibility layers that enable running Windows games on Linux. Proton, developed by Valve for Steam, has significantly improved the Linux gaming landscape.

Proton: Seamless Integration with Steam

Proton is integrated directly into Steam, allowing many Windows games to run on Linux with minimal configuration. Steam Play automatically uses Proton for compatible titles. The ProtonDB website provides compatibility reports for thousands of games, detailing performance and necessary tweaks. Experiment with different Proton versions (e.g., Proton Experimental, Proton GE) to find the optimal configuration for each game.

Wine: A Versatile Compatibility Layer

Wine (Wine Is Not an Emulator) is a more general-purpose compatibility layer that can run a wider range of Windows applications and games. Lutris is a game manager that simplifies the installation and configuration of games using Wine. Lutris provides pre-configured installation scripts for many games, streamlining the process.

Native Linux Games: A Growing Library

A growing number of games are natively available for Linux. These games offer the best performance and compatibility. Check the Steam store or GOG.com (which offers DRM-free games) for native Linux titles.

Addressing Anti-Cheat Compatibility

Anti-cheat systems, particularly kernel-level ones, pose a significant challenge to Linux gaming. Many anti-cheat solutions are incompatible with Wine and Proton. Games that rely on incompatible anti-cheat systems may not run on Linux or may require specific workarounds. Check ProtonDB for compatibility information regarding anti-cheat systems.
