  • The Availability Models of Two-Zone Physical Security System Considering Cyber Attacks
    Theory and Applications of Dependable Computer Systems, 2020
    Co-Authors: Kharchenko Vyacheslav S, Yuriy Ponochovnyi, Al-khafaji Ahmed Waleed, Artem Boyarchuk, Ievgen Brezhniev
    Abstract:

    Relevance of the paper is confirmed by the need to protect the Security Systems themselves, not only from Physical damage, but also from cyber attacks by intruders. The paper explores the Markov model of the two-zone cyber-Physical Security System. Evaluation of the functioning of the multi-zone System was carried out taking into account two degrees of degradation (operative condition - the failure state of all zones). The state space of the model (or one fragment) has a dimension of 9 states. In the proposed model, hardware failures caused by vandal attacks on objects of the first zone and software failures due to cyber attacks on the functions of the second zone are considered. The simulation results illustrate different transition intervals of availability indicators of various levels of degradation to a stationary state. For different degrees of degradation, the minimum value of the availability function, the time interval of the transition of the availability function to the stationary mode, and the value of the availability function in the stationary mode are determined. When eliminating software defects and vulnerabilities, the increase in the availability function is 0.23% for a zero level of System degradation.

    Co-Authors: Vyacheslav S Kharchenko, Yuriy Ponochovnyi, Al-khafaji Ahmed Waleed, Dmytro Uzun, Oleg Ivanchenko, Larysa Degtyareva
    Abstract:

    The article analyzes the process of functioning of Physical Security Systems in the conditions of component failures, cyberattacks and software updates. A zonal model of Physical Security Systems, which includes motion detection and access control subSystems, have been built. Updating the software functions of each zone, attacks on the Physical component of the motion detection subSystem, and cyber attacks on the access control System have been investigated. To model software updates, a multi-fragment model, including 9 states of each fragment and program update states has been created. To study the behavior of the model while changing the input parameters, Matlab scripts have been developed. Simulation results allow to evaluate the availability function minimum value, availability function value in stationary mode, time interval for the transition of the availability function to the stationary mode.

  • Fiber-optic vibration sensor for Physical Security System
    Proceedings of 2012 IEEE International Conference on Condition Monitoring and Diagnosis CMD 2012, 2012
    Co-Authors: Tatsuya Kumagai, Shinobu Sato, Teruyuki Nakamura
    Abstract:

    Physical Security technology is increasingly being used to prevent intruders from stealing or vandalizing property, leaking personal information, and threatening personal safety. Fences have been installed along the boundary of the premises of many public facilities to prevent any intrusion, and vibration sensors need to be easily fixable to these fences including around intricately shaped premises in order to adequately monitor a range of areas. Previously developed fiber-optic gyroscopes (FOGs), rotation sensors, and fiber-optic distributed temperature sensors (DTSs) are now used in various industrial Systems, and if such well-established technologies can be applied to vibration measurement, it is reasonable to expect stable characteristics and reliability under severe environmental conditions such as the Physical Security and health-monitoring of a structure. A Sagnac interference System of FOG and an optical time domain reflectometer (OTDR) function of DTS have been investigated for their potential application to vibration sensing. The detection of vibrating position was also investigated for each type of sensor.

  • Fiber-optic intrusion detection sensor for Physical Security System
    21st International Conference on Optical Fiber Sensors, 2011
    Co-Authors: Tatsuya Kumagai, Shinobu Sato, Wataru Ohnuki, Nakamura Teruyuki
    Abstract:

    The use of Physical Security technologies are becoming important to prevent intruders from stealing or vandalizing property, and leaking personal information, as well as to secure personal safety. At many important facilities, fences are installed along the boundary of the premises to prevent any intrusion. Vibration sensors need to be easily fixed to the fences even around intricately shaped premises for monitoring a wide range of areas. We have proposed and implemented a vibration sensor integrated with optical fiber and an optical interference System. To prevent any false or missing alarms, we have also investigated a signal processing System that can be used to judge whether an alarm is triggered by a natural phenomenon, small animals, or human intrusion.
