A computer security model is a scheme for specifying and enforcing security policies. 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.
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
The Protection of Information in Computer Systems is a 1975 seminal publication by Jerome Saltzer and Michael Schroeder about information security. [ 1 ] [ 2 ] The paper emphasized that the primary concern of security measures should be the information on computers and not the computers itself.
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]
Other examples of circular causal feedback include: technological devices such as the thermostat, where the action of a heater responds to measured changes in temperature regulating the temperature of the room within a set range, and the centrifugal governor of a steam engine, which regulates the engine speed; biological examples such as the ...
Social informatics is a young intellectual movement and its future is still being defined. However, because SST theorists such as Williams and Edge suggest that the amorphous boundaries between humans and technology that emerge in social shaping technology research indicate that technology is not a distinct social endeavor worthy of individual study, [6] indicating that there is a need for ...
Social simulation is a research field that applies computational methods to study issues in the social sciences.The issues explored include problems in computational law, psychology, [1] organizational behavior, [2] sociology, political science, economics, anthropology, geography, engineering, [2] archaeology and linguistics (Takahashi, Sallach & Rouchier 2007).
The term Social Information Processing Theory was originally titled by Salancik and Pfeffer in 1978. [4] They stated that individual perceptions, attitudes, and behaviors are shaped by information cues, such as values, work requirements, and expectations from the social environment, beyond the influence of individual dispositions and traits.
