Microsoft has taken a significant step forward in reshaping the future of gaming on Linux by announcing plans to remove kernel-level security measures. This decision, which stems from lessons learned after the Crowdstrike disaster earlier this year, could revolutionise the gaming experience for Linux users, especially on platforms like the Steam Deck. By eliminating kernel-level access for anti-cheat software, Microsoft is poised to make gaming on Linux more accessible and seamless.
In July, Microsoft faced severe backlash following the Crowdstrike outage, which disrupted global businesses and even grounded flights. As a response, Microsoft began contemplating a move to tighten the Windows kernel, ensuring future security issues would not arise. Fast forward to today, the company has officially committed to relocating security measures outside the kernel, as confirmed during the Windows Endpoint Security Ecosystem Summit.
A Win for Linux Gamers
The implications of this shift are profound, particularly for Linux gaming. Games running on Linux, particularly those reliant on compatibility tools like WINE and Proton, have often struggled with anti-cheat software embedded in the kernel. By shifting security measures to user mode, it becomes far easier for these tools to bypass the intrusive anti-cheat mechanisms, making games like Fortnite and Paladins potentially more accessible on Linux systems.
For Steam Deck users, this change could be transformative. The popular handheld gaming console relies heavily on Linux-based software, and many of the most popular games are rendered unplayable due to their dependence on kernel-level anti-cheat systems such as Easy Anti-Cheat (EAC). Though it’s often just a simple toggle to enable Linux compatibility, many game developers remain hesitant to do so, leaving Linux users out in the cold. With Microsoft’s new approach, this barrier may soon be a thing of the past.
A Cautious Move to Prevent Future Vulnerabilities
Microsoft’s blog post from the summit subtly acknowledges the Crowdstrike vulnerability as a key motivator for this change. Although the tech giant stops short of blaming the Crowdstrike disaster entirely, it is clear that the event served as a catalyst for rethinking the way security is handled on Windows systems. By decentralising security features, Microsoft aims to create a platform that is both tamper-proof and highly resilient.
At the summit, the company outlined its goals for a more secure platform, with a focus on performance, anti-tampering protection, and collaboration between Microsoft and its ecosystem partners. These measures are designed to address the key challenges faced by security vendors, ensuring they have the necessary tools to protect systems without needing kernel access.
Challenges Remain for Anti-Cheat Vendors
While Microsoft’s announcement is undoubtedly a step in the right direction, it remains to be seen how anti-cheat vendors will respond. There are still concerns that some vendors might find alternative ways to block Linux users from their games, even with kernel-level restrictions lifted. For now, it’s a waiting game to see how the wider gaming and security ecosystem will adapt to these changes.
The Future of Gaming on Linux
This move by Microsoft highlights a growing recognition of the importance of Linux gaming in the broader market. The company’s willingness to adapt and collaborate with its security partners demonstrates a commitment to addressing the evolving needs of both security providers and the gaming community. If anti-cheat vendors follow suit, the gaming landscape could become much more inclusive for Linux users in the near future.
In conclusion, Microsoft’s decision to shift security out of the kernel presents exciting possibilities for Linux gamers. With less intrusive anti-cheat software and improved compatibility with platforms like the Steam Deck, the future of gaming on Linux looks brighter than ever. However, only time will tell if game developers and anti-cheat vendors are willing to embrace this new, more open approach to security.
