There isn’t any doubt that the great CrowdStrike-Windows meltdown in July 2024 was an financial catastrophe. It was the biggest IT outage in historical past. Its results disrupted banking techniques, healthcare networks, and the worldwide air transportation community. Because the post-incident analyses made clear, it was fully preventable.

Within the wake of that incident, Microsoft convened a day-long Home windows Endpoint Safety Ecosystem Summit held earlier this week at its Redmond headquarters. The objective of the closed occasion, which was not open to the press or outdoors observers, was to deliver collectively what Microsoft referred to as “a various group of endpoint safety distributors and authorities officers from the US and Europe to debate methods for enhancing resiliency and defending our mutual clients’ important infrastructure.”
Did something helpful come out of the session? Who is aware of? Microsoft VP of Enterprise and OS Safety David Weston delivered a wrap-up of the session that was clearly scrubbed by attorneys and communication professionals till all that was left was optimistic company messaging and some obscure hints (“key themes and consensus factors”) of what would possibly occur in Home windows and in endpoint safety merchandise … sometime, however in all probability not quickly.

As that report notes, the roundtable “was not a decision-making assembly … we mentioned the complexities of the trendy safety panorama, acknowledging there are not any easy options.” However one theme that runs by way of the assembly abstract is a collective realization that the trade can not afford one other CrowdStrike incident.
The CrowdStrike incident in July underscored the accountability safety distributors should drive each resiliency and agile, adaptive safety. … We face a standard set of challenges in safely rolling out updates to the massive Home windows ecosystem, from deciding the way to do measured rollouts with a various set of endpoints to having the ability to pause or rollback if wanted. A core [Safe Deployment Practices] precept is gradual and staged deployment of updates despatched to clients.
That is a direct critique of CrowdStrike, which induced the IT outage by rolling out a flawed replace to its whole universe of gadgets relatively than utilizing a staged deployment that would have recognized the issue early and shut off updates to reduce widespread harm.
There’s barely extra shade within the feedback from assembly contributors that have been appended to the top of Microsoft’s company weblog put up, like this blast from Ric Smith, Chief Product and Expertise Officer of CrowdStrike competitor SentinelOne:
SentinelOne thanks Microsoft for its management in convening the Home windows Endpoint Safety Ecosystem Summit and we’re totally dedicated to serving to drive its objective of decreasing the possibility of future occasions just like the one attributable to CrowdStrike. We imagine that transparency is important and strongly agree with Microsoft that safety corporations should stay as much as stringent engineering, testing and deployment requirements and comply with software program growth and deployment finest practices. We’re proud that now we have adopted the processes that Microsoft has mentioned at present for years and can proceed to take action going ahead. [emphasis added]
Ouch.
What was clearly essentially the most energized dialogue, although, revolved round kernel-mode entry to Home windows, a key reason behind the CrowdStrike debacle. As I famous a number of months in the past, the scope of the CrowdStrike outage was due largely to the Home windows structure:
Builders of system-level apps for Home windows, together with safety software program, traditionally implement their options utilizing kernel extensions and drivers. As this instance illustrates, defective code working within the kernel house may cause unrecoverable crashes, whereas code working in consumer house cannot.
That was the case with MacOS as effectively, however in 2020, with MacOS 11, Apple modified the structure of its flagship OS to strongly discourage the use of kernel extensions. As an alternative, builders are urged to jot down system extensions that run in consumer house relatively than on the kernel degree. On MacOS, CrowdStrike uses Apple’s Endpoint Security Framework and says utilizing that design, “Falcon achieves the identical ranges of visibility, detection, and safety completely through a consumer house sensor.”
May Microsoft make the identical form of change for Home windows? Maybe, however doing so would definitely deliver down the wrath of antitrust regulators, particularly in Europe.
Within the broadest doable phrases, Microsoft’s put up refers to “platform capabilities Microsoft plans to make accessible in Home windows,” with a particular shout-out to safety defaults in Home windows 11 that “allow the platform to supply extra safety capabilities to resolution suppliers outdoors of kernel mode. Each our clients and ecosystem companions have referred to as on Microsoft to supply extra safety capabilities outdoors of kernel mode….”

Not each attendee is thrilled at that concept. Sophos CEO Joe Levy, for instance, politely famous, “We have been more than happy to see Microsoft help a lot of Sophos’ suggestions, primarily based on the gathering of architectural and course of improvements we have constructed over time and current at present on the 30 million Home windows endpoints we shield globally. The summit was an essential and inspiring first step in a journey that may produce incremental enchancment over time….”
What are these suggestions? In an August blog post, Sophos Chief Analysis and Scientific Officer Simon Reed made clear that the corporate considers entry to the Home windows kernel to be elementary. “Working in ‘kernel-space’ – essentially the most privileged layer of an working system, with direct entry to reminiscence, {hardware}, useful resource administration, and storage – is vitally essential for safety merchandise.” Kernel drivers are “elementary,” he wrote, not simply to Sophos merchandise however to “sturdy Home windows endpoint safety, on the whole.”
In an announcement that wasn’t attributed to a person, ESET was much more blunt:
ESET helps modifications to the Home windows ecosystem that display measurable enhancements to stability, given that any change should not weaken safety, have an effect on efficiency, or restrict the selection of cybersecurity options. It stays crucial that kernel entry stays an possibility to be used by cybersecurity merchandise to permit continued innovation and the power to detect and block future cyberthreats. We sit up for the continued collaboration on this essential initiative. [emphasis added]
And that, finally, is why it is unrealistic to count on any sweeping modifications within the Home windows platform any time quickly. These arguments from Sophos and ESET are clearly shared by leaders at different safety corporations, who worry that proscribing entry to the Home windows kernel will give Microsoft’s personal endpoint safety merchandise an important aggressive benefit.

That is the sort of debate that rapidly will get handed off from engineers to attorneys. Given Microsoft’s historical past with antitrust regulators in Europe and the US, it is more likely to find yourself in court docket. That is in all probability why “authorities officers from the US and Europe” have been invited attendees on the summit, and there is not any doubt they have been taking notes.
