On Windows, software regularly mucks around in the kernel (device drivers, system level tools like wireshark, etc), therefore it is also necessary for security software like CrowdStrike to also muck in the kernel so it can monitor what all the other kernel level software is doing. As demonstrated today, anything that mucks in the kernel runs the risk of crashing the kernel.
In Linux, software doesn't even get that option. Nothing ever gets kernel access except the kernel itself. Root is not kernel access. The kernel still decides what root is able to do. Drivers that require that access are built into the kernel. Software that requires deeper access like Wireshark tells the kernel what to do (through system calls as root) and the kernel does it on that programs behalf. Therefore, the kernel knows everything that any program does on the system. With a trustworthy kernel, all that security software must do is instruct the kernel to monitor activity on it's behalf.
