Access Control Models

This thesis intends to develop application-level access control models to address several major security issues in enterprise environments. The first goal is to provide simple and efficient authorization specifications to reduce the complexity of security management. The second goal is to provide dynamic access control for Web service applications. The third goal is to provide an access control framework for Semantic Web services. In this thesis, an Authorization-Function-Based Role-based Access Control (FB-RBAC) model is proposed for controlling enterprise systems at the application level.

When building a LAN that satisfies the needs of a small or medium-sized business, your plan is more likely to be successful if a hierarchical design model is used. Divided into discrete layers. Each layer has a specific purpose. Becomes modular – maintenance, performance.Interfaces with end devices. Routers, switches, bridges, wireless access points. Provides a means of connecting and controlling which devices are allowed to communicate on the network.

I model a “Tiebout”-style housing market in which house prices ration access to desirable schools, which may be desirable either because they are particularly effective or because they enroll a desirable set of students.

We have looked at protocols for distributing and establishing keys used for authentication and confidentiality But who should you give these keys to? Who should you trust? What are the rules governing when to and not to give out security credentials In this lecture, we will look at the broad area of secure and trusted systems We will focus on access control models These methods are often used to abstract the requirements for a computer system But, they hold for general systems where security is a concern (e.g. networks, computers, companies…) ...
