GIAC GCCC Question Answer

After installing a software package on several workstations, an administrator discovered the software opened network port TCP 23456 on each workstation. The port is part of a software management function that is not needed on corporate workstations. Which actions would best protect the computers with the software package installed?

Document the port number and request approval from a change control group

Redirect traffic to and from the software management port to a non-default port

Block TCP 23456 at the network perimeter firewall

Determine which service controls the software management function and opens the port, and disable it
