Abstract: PURPOSE: A security gateway device for a policy-based network security control and an operating method therefor are provided to dynamically meet a cyber terror by updating a correspondence policy according to a terror type in a policy cache when the cyber terror is generated and applying the updated policy to a newly generated cyber terror. CONSTITUTION: A CPA(Cyber Patrol Agent)(201) receives a cyber terror detection signal, and transmits the received cyber terror detection signal to a CPCS(Cyber Patrol Control System)(300). A policy receiving unit(202) receives a policy corresponding to the cyber terror detection signal from the CPCS(300). A security policy engine(203) receives the policies from the policy receiving unit(202), and outputs a dynamic security policy among the policies. A QoS(Quality of Service) policy executing engine(206) receives the policies from the policy receiving unit(202), and outputs a dynamic QoS policy among the policies. A security policy cache(204) receives the dynamic security policy from the security policy engine(203), and stores the received dynamic security policy according to the type of a cyber terror by a schema unit. A policy cache(205) receives the dynamic security policy of the schema unit from the security policy cache(204), receives the dynamic QoS policy from the QoS policy executing engine(206), updates policy information, and outputs updated policy information to the policy receiving unit(202) for dynamically corresponding to the cyber terror.

Abstract: An optimizing device and a method for signature are provided to improve memory efficiency of a security product by optimizing the signature generated through a signature generating system as a signature applicable to a security product. The contents which belong to signatures are separated when generating the signatures for the packet received from a network, and the separated contents are classified according to the attribution(S200). A sub signature including the classified contents is generated(S300). By measuring a false positive rate of the generated sub signature, the verification for the generated sub signature is performed(S400,S450). The sub signatures detected among the generated sub signatures are outputted as final signatures(S500).

Abstract: A signature optimizing system and a method thereof are provided to minimize the number of signatures generated against one attack. A signature generating device(20) produces the signature of a packet unit for a detected packet. A packet collecting unit(30) stores a flow which is doubted as an attack among flows inputted through a network, and extracts a flow corresponding to the generated signature among the inputted flows. A verifying device(40) determines whether the extracted flow is for an attack. A signature optimizing device(50) classifies signatures generated through the signature generating device according to the sign of attack confirmed by the verifying device, and then generates the final signature from the classified signatures.
