Why Be Concerned With AATools security TCP/ UDP Port Scanner?
TCP and UDP use port numbers to identify higher-layer services. Systems administrators use the port scanner to determine what TCP/UDP services are available on a server. A cardinal rule of server security is to disable any service that the system isn’t using because any open TCP/UDP service offers intruders a possible entry into your system. Thus, you can use the port scanner to ensure that only the desired TCP/UDP services are running on your server. This information is rather critical for developing and/or verifying security policies. The AATools Port Scanner will return which TCP or UDP ports are listening. You should check these ports to see if they are running services that you have approved. If they are running services which are undocumented, or which you do not wish to run, we suggest you disable them. Many operating systems are shipped with a large number of services that are not required for normal operation. In some cases these services may contain known or unknown security
