Abstract

Defense in Depth (DiD) is one of the most basic and fundamental cybersecurity strategies that uses layers of protection in order to protect systems and information from different and new kinds of threats. DiD as an approach involves linking several security controls and processes at the network, application and data, and physical levels in an effort to counteract an attack and minimize chances of a single vulnerability point. In this chapter, the authors analyze DiD as a concept and investigate whether it can effectively prevent or at least timely recognize and counter advanced cyber threats. Here, we identify important defense layers, how they work together, and issues related to DiD in a dynamic context. Further, the threats and innovations in DiD are assessed to inform the adaptation of the cybersecurity strategies within organizations in a constantly evolving threat environment.
