- SSH
This script will generate a notice if an apparent SSH login originates or heads to a host with a reverse hostname that looks suspicious. By default, the regular expression to match “interesting” hostnames includes names that are typically used for infrastructure hosts like nameservers, mail servers, web servers and ftp servers.
