Abstract: A system including a network communication device, a storage device, and a controller is provided. The storage device stores first mappings between IP addresses and devices, and second mappings between software and devices. The controller obtains a connection log from the proxy server or the firewall device via the network communication device, uses the first mappings and the second mappings to analyze the connection log to determine one or more different connections between connections of devices on which first software is installed and connections of devices on which the first software is not installed, determines whether the first software functions normally on a first device blocking the different connections, and adds destination addresses of the different connections into a blocking list in response to the first software functioning normally on the first device, such that the proxy server or the firewall device blocks all connections towards the destination addresses.
