Information systems are vulnerable to accidental or malicious attacks. Security models for commercial computer systems exist, but information systems security is often ignored or added at or after implementation. The paper explores common security 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 multi-level security (MLS) systems described in the Orange Book.
The Clark -Wilson (CW) model is an integrity, application level model which attempts to ensure the integrity properties of commercial data and provides a framework for evaluating security in commercial application systems. It was published in 1987 and updated in 1989 by David D. Clark and David R. Wilson (a computer scientist and an accountant). Therefore in a previous work [4] we showed the general feasibility of the Clark-Wilson security model [5] for digital long-term preservation in combination with a syntactic and semantic verification approach [6] to tackle these issues.

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.
Therefore in a previous work [4] we showed the general feasibility of the Clark-Wilson security model [5] for digital long-term preservation in combination with a syntactic and semantic verification approach [6] to tackle these issues. security levels of network devices, operating systems, hardware, protocols, and applica-tions can cause security vulnerabilities that can affect the environment as a whole. Two fundamental concepts in computer and information security are the security model, which outlines how security is to be implemented—in other words, providing a
LaPadula Model. 2. A Security Model Based on Information Flow The general security model that is most self-consciously based on information theory is Sutherland’s Nondeducibility Model [16]. This model states that information flows in a system from high-level objects to low-level objects if … The model was described in a 1987 paper (A Comparison of Commercial and Military Computer Security Policies) by David D.
