Microsoft calls for Windows changes and resilience after CrowdStrike outage

Microsoft is inactive helping CrowdStrike cleanable up the mess that kicked disconnected a week agone erstwhile 8.5 cardinal PCs went offline owed to a buggy CrowdStrike update. Now, the bundle elephantine is calling for changes to Windows, and has dropped immoderate subtle hints that it’s prioritizing making Windows much resilient and consenting to propulsion information vendors similar CrowdStrike to halt accessing the Windows kernel.

While CrowdStrike has blamed a bug successful its investigating software for its botched update, its bundle runs astatine the kernel level — the halfway portion of an operating strategy that has unrestricted entree to strategy representation and hardware — truthful if thing goes incorrect with CrowdStrike’s app past it tin instrumentality down Windows machines with a Blue Screen of Death.

CrowdStrike’s Falcon bundle uses a peculiar operator that allows it to tally astatine a little level than astir apps truthful it tin observe threats crossed a Windows system. Microsoft tried to restrict 3rd parties from accessing the kernel successful Windows Vista successful 2006, but was met with pushback from cybersecurity vendors and EU regulators. However, Apple was capable to fastener down its macOS operating strategy successful 2020 truthful that developers could nary longer get entree to the kernel.

Now, it looks similar Microsoft wants to reopen the conversations astir restricting kernel level entree wrong Windows.

While Microsoft doesn’t item the nonstop improvements it volition marque to Windows successful the aftermath of the CrowdStrike issues, Cable does driblet a fewer clues astir which absorption Microsoft wants to spot things go. Cable calls retired a caller VBS enclaves diagnostic “that does not necessitate kernel mode drivers to beryllium tamper resistant” and Microsoft’s Azure Attestation work arsenic examples of caller information innovations.

“These examples usage modern Zero Trust approaches and amusement what tin beryllium done to promote improvement practices that bash not trust connected kernel access,” says Cable. “We volition proceed to make these capabilities, harden our platform, and bash adjacent much to amended the resiliency of the Windows ecosystem, moving openly and collaboratively with the wide information community.”

These hints mightiness footwear disconnected a speech astir Windows kernel access, adjacent if Microsoft claims it can’t partition disconnected its operating system successful the aforesaid mode arsenic Apple owed to regulators. Cloudflare CEO Matthew Prince has already warned astir the effects of Microsoft locking down Windows further, truthful Microsoft volition request to cautiously see the needs of information vendors if it wants to prosecute existent change.
