Okay but that means that the brute force attack can just continue
because the attacked daemon will be respawned?
You need some way to stop the respawning, otherwise the
mitigation doesn't work for daemons.
I will work on your solution regarding respawned daemons (use wait*() to inform
userspace that the offending processes killed by the mitigation exited due to
this mitigation -> then the supervisor can adopt their own policy).
