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.

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.

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.

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.
