Close Port on ACS Solution Engine, posibble?

c.ong · ‎01-28-2008

Hi Sir,

I did a portscan on the ACS solution engine and found the following TCP ports are open on the ACS Solution Engine,

Port - Services

49 - TCPwrapped

135 - MSRPC

1503 - TCPwrapped

1506 -TCPwrapped

2000 - Calbook

2001 - DC

2002 - SSL

2003 - cfingerd

3389 - TCPwrapped

I would like to know whether the ports open above is required for the optimum operation of the ACS SE. If not, I plan to close some of the ports such as 135 and 3389. Please advise the impact if such ports above are close

Thanks.

Delon

You can block port 3389 which is used by cfingerd and this will not have any impact on the performance of the device. However the ports used by TCPwrapped should not be blocked as they are connection ports used for communication with other hosts.
