Assessing the Value of Investments in Network Security Operations: A Systems Analytics Approach - Griffin, Jonathan; Monahan, Brian; Pym, David; Wonham, Mike; Yearworth, Mike
Keyword(s): modelling; mathematics; information security; operations; business value
Abstract: Assessing the value of investments in network security operations remains a challenging problem. We suggest that an essential component of an analysis of this problem must be an account of the structure of the system/network and the services it is intended to deliver. We apply the methods of classic ...
