Primarily through computer hacking open port system, the other side of the computer intrusion. Close some ports can also calculate risk reduction of system vulnerabilities. Legitimate users of the port to open the more channels the more into the system. Therefore, in order to make the system normal operation, shut down some useless port, try to keep a small port is very necessary. With the netstat command run locally to test which ports are open, the safest method is still outside the system port scan, check for each port are running about. Can not confirm any of the port must be closed, the final list of the ports should be recorded to ensure that no additional ports appear.
