What makes CrowdStrike so ubiquous that their error created such catastrophe? (sh.itjust.works)

What CrowdStrike is actually selling, is someone who actually looks at the system logs and who pushes a button when something pops up. Roughly.

There are better solutions on the market. Unfortunately CrowdStrike has the more aggressive sales team.

For those wondering, I’m referring to *nix based solutions like SElinux, appArmor, iptables, nftables, cgroups, … But you need to monitor your logs if you want to take appropriate action.

The problem with SELinux/nftables/cgroups is that they don't come with a centralised log aggregator, and they don't do much blocking beyond the defaults for 99% of deployments.

You must not have heard of (r)syslog.

Also, SELinux is a massive pain to set up (even compared to AppArmor), and setting it up correctly is even worse.

I beg to differ, I find SELinux easy to setup. But your mileage may vary, depending on one’s experience.

CrowdStrike does a lot of what SELinux does but it's easier to configure, works on every operating system, and comes with tools to roll out configuration across an organisation. There's nothing close to that in the open source world. Even if you set up something yourself, you'll need to continuously tweak your setup not to get in the way of employees and to prevent alert fatigue from all of the false positives. Apparently, recent events show it doesn’t work on every OS… 😜

When talking about ease of use… Configuration is configuration. If you do not take the time to learn how to use your product, the product you know will always be better than the one you don’t. I’ve used Crowdstrike. I’ve battled them to get their kernel modules signing certificate to be signed by RedHat. I’ve battled them to have the possibility to have the auto update disabled. So no, I am not impressed by the quality of their product. I’ll bet any day a vanilla RHEL with the correct security related software and the latest updates outperforms and outclasses Crowdstrike.

I think a preconfigured solution like Security Onion combined with tons of group policy and Ansible can form an open source alternative, but that only monitors, whereas CrowdStrike also blocks. To block behaviour, you'll need to write code for most platforms, and that's just as likely to take down your org as an auto update from CrowdStrike. I can’t speak of MS products, as I have not managed them for 20 years, but all of this is not needed on a decent Linux distro.
