    摘要: An apparatus and method for controlling traffic based on a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) are provided. The traffic control apparatus includes a traffic monitoring unit, a CAPTCHA verification unit, a list management unit, and a traffic control unit. The traffic monitoring unit monitors a packet between an internal network and an external network. The CAPTCHA verification unit, if packet information is not present in an access control list, sends a CAPTCHA request message to a client computer, receives a CAPTCHA response message, and verifies the CAPTCHA response message. The list management unit, if the packet information is present in the access control list, detects an access control policy corresponding to the packet information in the access control list. The traffic control unit controls traffic based the verification of the CAPTCHA response message and the control policy.

    摘要: A referer verification apparatus and method for controlling web traffic having malicious code are provided. In the referer verification method, whether a referer is present in a Hypertext Transfer Protocol (HTTP) packet is determined. If it is determined that the referer is present in the HTTP packet, Uniform Resource Locators (URLs) are extracted from a referer web page corresponding to the referer. The referer is verified based on a URL corresponding to a referer verification request received from a server and the extracted URLs. A Completely Automated Public Test to tell Computers and Humans Apart (CAPTCHA) verification procedure conducted by a user is performed based on results of the verification of the referer.

    摘要: A system and method for detecting network intrusion by using a network processor are provided. The intrusion detection system includes: a first intrusion detector, configured to use a first network processor to perform intrusion detection on layer 3 and layer 4 of a protocol field among information included in a packet header of a packet transmitted to the intrusion detection system, and when no intrusion is detected, classify the packets according to stream and transmit the classified packets to a second intrusion detector; and a second intrusion detector, configured to use a second network processor to perform intrusion detection through deep packet inspection (DPI) for the packet payload of the packets transmitted from the first intrusion detector. Thereby, intrusion detection for high-speed packets can be performed in a network environment.
