Selection the perimeter protection equipment in security systems

Information systems are being developed rapidly nowadays. The biggest challenge for all organizations is to find the best way to protect important information of an organization. So, information systems security has become an important area of concern for all organizations. Materials which presented in this paper are a review of the technical characteristics of physical systems security equipment, the standards supported and also administrative regulations of information systems security. The combination of perimeter protection and administrative regulations are needed to prevent the unauthorized penetration to protected zone and formation the prohibited request. The findings of this review can be useful to researchers and designers of security systems for optimization their structure. Various equipment parameters indicated in this paper can be also used for increasing the accuracy of estimating the reliability of security systems by means of simulation.
