It needs that kind of access to fight advanced attacks. It would surprise me if similar EDR programs didn't have similar access on Linux systems, for example.
No, you make a management API for security products that run in user space as root, you don't use kernel modules.
Is that the way that EDR is implemented on Linux or are you guessing?
Currently, cloudstrike offers two methods for Linux: a kernel driver / module and a theoretically safer alternative using epbf (you could call that "kernel level scripting"). Ironically, they triggered a kernel bug using that second option. They did not test all kernels they listed as compatible or something like that.
