These formal policy models can be categorized into the core security principles of Confidentiality, Integrity, and Availability. For example, the Bell-La Padula model is a confidentiality policy model, whereas the Biba model is an integrity policy model. [1]
The model was described in a 1987 paper (A Comparison of Commercial and Military Computer Security Policies) by David D. Clark and David R. Wilson.The paper develops the model as a way to formalize the notion of information integrity, especially as compared to the requirements for multilevel security (MLS) systems described in the Orange Book.
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.
Policy and practices: administrative controls, such as management directives, that provide a foundation for how information assurance is to be implemented within an organization. (examples: acceptable use policies or incident response procedures) - also referred to as operations.
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 ...
The Cyber Assessment Framework is a mechanism designed by NCSC for assuring the security of organisations. The CAF is tailored towards the needs of Critical National Infrastructure, to meet the NIS regulations, [1] but the objectives can be used by other organisations.
The Biba Model or Biba Integrity Model developed by Kenneth J. Biba in 1975, [1] is a formal state transition system of computer security policy describing a set of access control rules designed to ensure data integrity. Data and subjects are grouped into ordered levels of integrity.
