Summary
The remote host has the three TCP ports 822, 1750, 1751 open.
It's very likely that this host is an Arkoon security dedicated appliance with ports
TCP/822 dedicated to ssh service
TCP/1750 dedicated to Arkoon Manager
TCP/1751 dedicated to Arkoon Monitoring
Letting attackers know that you are using an Arkoon appliance will help them to focus their attack or will make them change their strategy.
You should not let them know such information.
Solution
do not allow any connection on the
firewall itself, except for the firewall
protocol, and allow that for trusted sources
only.
If you have a router which performs packet
filtering, then add ACL that disallows the
connection to these ports for unauthorized
systems.
