2010 International Conference on Emerging Security Technologies A Systems Engineering Approach For Security System Design Ian Alston & Simon Campbell Selex Galileo Ltd [email protected], [email protected] – Physical security systems Those which protect a facility, resource or Abstract physical media (electronic or hard copy). The number of application areas where security of – Information security systems resources, whether this is people, information or physical Those which protect data from unauthorized property, is ever increasing as our world culture changes access, use, disclosure, destruction, modification, and the potential threats to individuals rises. The threats or disruption to access. that security systems need to mitigate against are In both cases, the security system can be thought of as becoming both more complex and also asymmetric. In a set of processes and functions that protect a resource association with this the number of emerging technologies (physical or data) from access or malicious use. While that can be applied to security systems is also increasing, there are many different types of security systems that can and together with current & changing threats, is resulting be used in many application areas, the fundamental in a more complex system with many interacting and problem is no different to developing any type of possibly distributed elements. This paper describes how engineering solution i.e. develop a system that meets the Systems Engineering provides a methodical design customer requirements and functions as intended subject approach enabling a design engineer to understand all to internal and external constraints while being the contributing factors and analysing the implemented with the most appropriate technologies. An cost/performance trade of alternative solutions. It shows essential element in today’s world of challenging budgets that security...
