SSH hardening with Breakinguard

Attacks against SSH services are regularly seen in the wild. Even if you follow best practices for securing the service, the malicious scans will utilise resources available to your environment; CPU, bandwidth etc. In sufficient volume legitimate operation may be impacted as the server rejects failed login attempts.
This is where utilities like Breakinguard come into their own. Basically Breakinguard monitors log files for signs of malicious activity, and once a single source has triggered enough alerts blocks all connections from the source location.
