Intrusion Detection Systems in the Protection of Assets
Faculty of Health, Engineering and Science
School of Computer and Security Science
The chapter critiques Intrusion Detection Systems (IDS) as applied in the domestic and commercial environments in the protection of assets, with Defence in Depth providing an underlying strategy. IDS is the integration of technology and processes, with taxonomies of sensing detectors and applied levels of environmental security. Therefore, the chapter raises issues in the efficacy and application of IDS. Efficacy issues include the degree of deterrence provided and the ability to detect intrusion. Whether IDS alters deviant environmental behaviour and why users choose IDS over other strategies. Application issues include the Electronic Security sector itself, regulatory regimes, quality of installation and the false alarm rates. These, amongst others, are factors that affect the efficacy of IDS. To conclude, the future of these systems and further research that could improve our understanding of IDS is presented.
