  • Patent number: 9438641
    Abstract: An apparatus and method for detecting potentially-improper call behavior (e.g., SPIT, etc.) are disclosed. The illustrative embodiment of the present invention is based on finite-state machines (FSMs) that represent the legal states and state transitions of a communications protocol at a node during a Voice over Internet Protocol (VoIP) call. In accordance with the illustrative embodiment, a library of FSM execution profiles associated with improper call behavior is maintained. When there is a match between the behavior of a finite-state machine during a call and an execution profile in the library, an alert is generated.

  • Patent number: 9407661
    Abstract: A security device may receive a request from an attacker device and intended for a server device. The security device may identify the request as being associated with a malicious activity. The malicious activity may include one or more undesirable tasks directed to the server device. The security device may generate an unsolvable challenge-response test based on identifying the request as being associated with the malicious activity. The unsolvable challenge-response test may be generated using at least one construction technique and may be configured in an attempt to block the attacker device without making the attacker device aware that the attacker device is being blocked. The security device may provide the unsolvable challenge-response test to the attacker device, and may receive a solution associated with the unsolvable challenge-response test. The security device may notify the attacker device that the solution is incorrect regardless of whether the solution is actually correct.

  • Publication number: 20150121975
    Abstract: A locking device for obstructing towing of an unattached trailer has a lock base and a single-armed curved interlock bracket. The lock base has a cylindrical leg. The single-armed interlock bracket has an grooved arm sliding along an aperture on the cylindrical leg and may be permanently attached to the lock base. Grooves on the arm allows a locking means to be engaged with the lock bracket at different height. When engaged, the locking means may restrict the interlock bracket from swirling. The open end of the interlock bracket provides flexibility to accommodate trailer couplers with different cap/rim sizes. The cylindrical leg may have a sealed bottom end and may function as a handle. The locking device may also feature a push-in locking mechanism to lock the interlock bracket in a position without using a key.

  • Patent number: 8444167
    Abstract: A hitch lock device for preventing theft of a trailer featuring a hitch ball with a threaded bolt and a nut adapted to be threaded onto the bolt. Locking pin slots are disposed in the threaded bolt. A lock can be inserted into a slot in the threaded bolt. Locking pins are slidably disposed in each locking pin slot. The locking pins are connected by a spring and can move between an in position in the threaded bolt and an out position protruding from the bolt. The pins are biased in the out position by the spring. When the locking pins are squeezed to the in position the nut can be threaded past the locking pins to sandwich a trailer hitch with the hitch ball. When the lock is inserted into the slot the lock blocks movement of the locking pins and locking the lock prevents removal of the lock.

  • Patent number: 7665334
    Abstract: An outboard motor lower-unit lock has a key, a locking pin assembly and a shaft. To install the lock, a user drills a shaft hole the same diameter as the shaft through both sides of a housing unit below an access hole of the housing unit. The shaft is inserted in the shaft hole, and oriented so that a threaded hole in the center of the shaft can receive a threaded pin section of the locking pin. The locking pin receives the key. The key is tightened. Finally, the user removes the key allowing the locking pin to rotate around and below the shaft, thereby obstructing a bolt securing the lower-unit to the housing unit, and preventing the unauthorized removal of the lower-unit.

  • Patent number: 7441429
    Abstract: With the widespread adoption of SIP-based VoIP, understanding the characteristics of SIP traffic behavior is critical to problem diagnosis and security protection of VoIP services. A general methodology is provided for profiling SIP-based VoIP traffic behavior at several levels: SIP server host, server entity (e.g., registrar and call proxy) and individual user levels. Using SIP traffic traces captured in a production VoIP network, the characteristics of SIP-based VoIP traffic behavior in an operational environment is illustrated and the effectiveness of the general profiling methodology is demonstrated. In particular, the profiling methodology identifies anomalies due to performance problems and/or implementation flaws through a case study. The efficacy of the methodology in detecting potential VoIP attacks is also demonstrated through a test bed experimentation.
