摘要： An internal tracing method for network attack detection is used to trace whole life cycle of an attack data packet for test in different phases such as an attacking phase, a defending phase, and an attacked phase through configuring and uniting three parties including an attack end point (AEP), a detect end point (DEP), and a target end point (TEP) and setting a corresponding internal check point in each part when testing a network intrusion detection system (IDS). In other words, when testing the network IDS, in a whole period that the attack data packet for test is attacking, filtered, detected, and finally transmitted to a target host, a tester may clearly know the statuses and information of the data packet in each important phase, thereby generating a test report conveniently, quickly, and accurately.

摘要： A method of processing an external service request in a storage area network (SAN) is used for responding a service request in the SAN with multiple controllers, and the method includes the following steps. A first controller of the SAN receives a request packet of an external network. When the first controller determines that the request packet must be transmitted to a second controller actually providing service in an internal network, the request packet is transmitted to the second controller. The second controller receives the request packet, and parses a source address contained therein for recording. The second controller executes an operation instruction corresponding to the request packet, and then generates an acknowledge packet. The second controller takes the source address as a destination address of the acknowledge packet and directly transmits the acknowledge packet to an original request initiator.
