Security process

[Walter]

I got curious about BSD (DragonFly, specifically) security and
wondered why there wasn't a security process that processed all
security-relevant error messages which could then be used to
block IPs, disable user accounts, and kill processes.  At least
it'd be a step to automating *some* obvious security measures
rather than requiring root action.  Things like repeated login-
in failures from external (as in China) IPs.  Anyone?
