Port Scanner is an advanced network utility for finding ports that are open on any machine or range of machines on a network. CyD Port Scanner can scan any class A, B or C network for any list of open ports. Finding open ports on a host can be one of many things. An open port can be a server service like FTP or HTTP that a user on the node may or may not be allowed to run under the network's administration rules. An open port may also be a backdoor Trojan program that a hacker installed through a virus or remote administration exploit.
It is very important to find these holes in your network because any machine that can be compromised on your network brings a hacker one step closer to having full administrative privleges on your network, and ultimately destroying important data, or even spying on sensitive data.
To run port scanner, select the Scan ports item from the Network menu or press 
. A Scan ports module will be displayed:
In the module you must choose the scanning type you want to use - TCP or UDP. Type the IP address you want to scan and press the 
button .
Other toolbar buttons:
- cancel scanning;
