In a real-time network attack pattern detection system and method, a common pattern is detected in real time from packets, which are suspected to be a network attack such as Worm, to effectively block the attack. The system includes: a suspicious packet detector for classifying a suspicious attack packet from all input packets; a first data delaying unit for receiving the input packet from the suspicious packet detector to output an one-clock delayed data; a second data delaying unit for receiving an output signal from the first data delaying unit to output an one-clock delayed data; a hash key generator for receiving an output data of the suspicious packet detector, an output data of the first data delaying unit and an output data of the second data delaying unit to generate a hash key; a hash table for storing a lookup result obtained by the hash key generated from the hash key generator; and an existence & hit checker for checking the lookup result of the hash table.

Provided is an intrusion detection apparatus and method using patterns. The intrusion detection apparatus using patterns for performing intrusion detection by receiving indices of matched intrusion detection rules which are results of matching payload parts and IP (Internet protocol) address parts of packets, includes: a rule generator classifying intrusion detection rules into rules having content examination parts and rules without content examination parts, granting an index to each of the rules so as to output the indices to a unit for performing the matching and to simultaneously store the indices; an extractor extracting payload parts and address parts from the packets and outputting the extracted payload parts and address parts to the unit; and an examination unit examining corresponding rules based on the indices. Accordingly, an overload due to examinations which are performed on all rules for malicious packets whenever packets are input, is reduced, so that processing speed can be increased. Therefore, an implementation of a system having an effective performance and a relatively low cost that can replace a high-cost and high-performance hardware dedicated system is possible.
摘要:
A hammer system for automatically carrying out a standard penetration test is disclosed. A cylindrical housing, in which an anvil coupled to a drill rod is received, is supported by a first hydraulic cylinder coupled to boring equipment. A cylindrical hammer is received in the housing. The hammer includes a holding assembly therein, which selectively holds and raises the hammer by a second hydraulic cylinder. Element for limiting a stroke of the hammer is spacedly connected to the holding assembly to be raised and lowered therewith. The limiting element includes a first sensor to detect a slot formed at the housing when the hammer is raised, thereby counting the number of blows. The hammer includes a plurality of protrusions on its outer surface. A wall of the housing includes a second sensor to detect the number of protrusions passed over the second sensor when the hammer is raised, thereby calculating a penetration depth from a difference between the numbers of protrusions detected for two continuous blows.
摘要:
An apparatus and method are described that may enable a target device to communicate with a source device using a wireless power. The communication apparatus receives a wireless power from a source resonator through a magnetic coupling between the source resonator and a target resonator. The communication apparatus transmits a message, and modulates the message based on the received wireless power and impedance mismatch between the source device and the target device. The communication apparatus controls the impedance mismatch by changing an impedance of the target device.
