What is Security Model

Handbook of Research on Modern Cryptographic Solutions for Computer and Cyber Security
A security model is a computer model which is used to identify and impose security policies. It does not require any prior formation it may be founded on the access right model or distributing computing model or computation model.

Numerous vulnerabilities have a tendency to taint modern real-world web applications, allowing attackers in retrieving sensitive information and exploiting genuine web applications as a platform for malware activities. Moreover, computing techniques are evolved from the large desktop computer systems to the devices like smartphones, smart watches and goggles. This needs to be ensure that these devices improve their usability and will not be utilized for attacking the personal credentilas (such as credit card numbers, transaction passwords, etc.) of the users. Therefore, there is a need of security architecture over the user's credentials so that no unauthorized user can access it. This chapter summarizes various security models and techniques that are being discovered, studied and utilized extensively in order to ensure computer security. It also discusses numerous security principles and presents the models that ensure these security principles. Security models (such as access control models, information flow models, protection ring, etc.) form the basis of various higher level and complex models. Therefore, learning such security models is very much essential for ensuring the security of the computer and cyber world.

Understanding Computer Security
A security model is a framework in which a security policy is developed. The development of this security policy is geared to a particular setting or instance of a policy, for example, a security policy based upon authentication, but built within the confines of a security model. For example, designing a security model based upon authentication and authorization, one would consider the 4-factor model of security, that is, authentication, authorization, availability, and authenticity.

PolyOrBAC: An Access Control Model for Inter-Organizational Web Services
rigorously defines a security policy. Generally, a security model is a “formal system” used to specify and reason on the security policy (i.e., it is used as a basis for formal specification proofs). It is thus intended to abstract the security policy and handle its complexity; represent the secure states of a system as well as the way in which the system may evolve, verify the consistency of the security policy, detect and resolve possible conflicts.
