摘要： PURPOSE: A VoIP spam blocking device using the spam index is provided, which blocks spam effectively by analyzing a telephone call pattern of a spammer. CONSTITUTION: Data extractor(122) extracts a CDR(Call Detail Record) of a caller terminal using a VoIP(Voice over Internet Protocol). A spam index calculator(124) produces a spam index reflecting a call pattern information of the caller terminal using the CDR. If the spam index is over the standard value, a spammer list generator(126) registers the caller terminal in the spammer list. The spam index is calculated by mixing a receiver index, a conversation time index, a traffic index, a receive refuse index, a call interval index, and a sending attempt index of the caller terminal.

摘要： An attacking multimedia packet blocking device and a system and method therefor are provided to drop an attacking multimedia packet selectively by filtering a received RTP(Real-time Transport Protocol) packet, thereby offering a stable multimedia service. An IP(Internet Protocol)/port blacklist(242) registers and manages IP/port information which is a blocking target. A blacklist filter(241) inquires about the registered IP/port information to drop a received RTP packet if the information is identical with an IP/port of the received RTP packet. An unregistered session RTP packet filter(243) compares an SSRC(Synchronization Source) and the IP/port of the filtered packet with an SSRC and IP/port information registered as a normal user, and selectively drops the RTP packet. A register session memory(244) provides the IP/port information and the SSRC information registered as the normal user of the RTP packet to the packet filter. A disguise RTP packet filter(245) calculates a difference between a time stamp and a sequence number of the RTP packet with a time stamp and a sequence number of a right-before received RTP packet, and selectively drops the received RTP packet based on the calculated value.

摘要： A security system of a call signaling message for an SIP(Session Initiation Protocol)-based VoIP(Voice over Internet Protocol) service and a method thereof are provided to block messages which are not suitable for message grammar or include blocking information registered in a blocking list or are not proper for message session states, thereby preventing an attack on a call signaling message. A message suitability verification module(10) receives call signaling messages transmitted between a terminal(1) and a server(2), blocks call signaling messages which do not comply with preset types, and delivers not-blocked call signaling messages. A filtering module(20) receives the call signaling messages, blocks call signaling messages including blocking information registered in a prestored blocking list, and delivers not-blocked call signaling messages. A message state verification module(30) receives the call signaling messages, blocks call signaling messages which do not correspond to session states, and transmits not-blocked messages to the terminal or the server.

摘要： A secure SBC for a safe VoIP(Voice over Internet Protocol) service is provided to ensure call availability in an existing Internet network by providing the VoIP service even in a private IP(Internet Protocol) through an NAT/FW pass function, and to protect equipment within a network by providing a network covert function. A session control module controls session generation, management and data exchange between terminals. The session control module comprises an SIP(Session Initiation Protocol) signaling control server(101), a media relay management server(102) and a media relay worker server(103). A secure module detects and intercepts a malicious call and media. The secure module comprises an SIP detector(104), an SIP filter(105), a media detector(106), a media filter(107) and a policy manager(108). A management module manages element of a system, and reports information about the system. A database(111) stores and manages information so as to assign basic information of detection and interception and to reflect current system resource state information to a secure policy. The management module comprises the followings. An EMS(Element Management System)(109) manages a network of a secure SBC(Session Border Controller) system and manages and operates system elements. An EVTS(Event Server)(110) collects log or state information of each element of the system, and reports the information so as to be reflected to the policy manager.
