The Gordon–Loeb model is an economic model that analyzes the optimal level of investment in information security. The benefits of investing in cybersecurity stem from reducing the costs associated with cyber breaches. The Gordon-Loeb model provides a framework for determining how much to invest in cybersecurity, using a cost-benefit approach.
Hal Varian presented three models of security using the metaphor of the height of walls around a town to show security as a normal good, public good, or good with externalities. Free riding is the end result, in any case. Lawrence A. Gordon and Martin P. Loeb wrote the "Economics of Information Security Investment". [1]
It does not model the rules by which permissions can change in any particular system, and therefore only gives an incomplete description of the system's access control security policy. An Access Control Matrix should be thought of only as an abstract model of permissions at a given point in time; a literal implementation of it as a two ...
A security model may be founded upon a formal model of access rights, a model of computation, a model of distributed computing, or no particular theoretical grounding at all. A computer security model is implemented through a computer security policy. For a more complete list of available articles on specific security models, see Category ...
The HRU security model (Harrison, Ruzzo, Ullman model) is an operating system level computer security model which deals with the integrity of access rights in the system. It is an extension of the Graham-Denning model, based around the idea of a finite set of procedures being available to edit the access rights of a subject on an object .
Generally, security modes refer to information systems security modes of operations used in mandatory access control (MAC) systems. Often, these systems contain information at various levels of security classification. The mode of operation is determined by: The type of users who will be directly or indirectly accessing the system.

Information security standards (also cyber security standards [1]) are techniques generally outlined in published materials that attempt to protect a user's or organization's cyber environment. [2] This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services ...
