Apparatus and method for defending against internet-based attacks
A system for defending against internet-based attacks is disclosed. The system may include a processor which may be configured to receive information associated with a device when a web request is transmitted by the device to access a web page monitored by the processor. The processor may also determine whether traffic associated with the web request from the device is suspected of being used for malicious activity and, if not, enable the device to access the web page. If the traffic is suspected of being used for malicious activity, then the processor may transmit a challenge to the device if the traffic is determined to be suspected. Furthermore, the processor may receive information associated with the web request, which may be provided by a uniform resource locator invoked in response to the traffic being determined to be suspected.
