comment OS (or platform) agnostic metrics to understand if a system is compromised?
Another area to look for is to monitor network traffic. This could be as simple as verifying active connections using netstat for over a period of time.

comment How to prevent attacks to server
Not aware of your network set-up but is there a need to have sshd open to public ? Is there any firewall involved ?
