The remote host seems to be a Checkpoint FW-1 running SecureRemote. Letting attackers know that you are running FW-1 may enable them to focus their attack or will make them change their attack strategy. You should not let this information leak out. Furthermore, an attacker can perform a denial of service attack on the machine.

Restrict access to this port from untrusted networks. For More Information: http://www.securiteam.com/securitynews/CheckPoint_FW1_SecureRemote_DoS.html
