Analyzing and Developing Role-Based Access Control Models

Role-based access control (RBAC) has become today's dominant access control model, and many of its theoretical and practical aspects are well understood. However, certain aspects of more advanced RBAC models, such as the relationship between permission usage and role activation and the interaction between inheritance and constraints, remain poorly understood. Moreover, the computational complexity of some important problems in RBAC remains unknown. In this thesis we consider these issues, develo

By the end of this unit you should be able to:

understand the common issues that arise in projects;

practise project management tools and techniques;

understand how to avoid some of the common problems that arise in project management;

practise project management decisions;

understand the interaction of the rational and the more subjective and affective elements of project management.

The default learning path in this unit takes a problem-based approach to learning about project management. You work through a realistically complex and messy example of project management and engage in a series of tasks associated with the case-study materials. At each stage of the case study you have access to project management resources which describe useful approaches to project management and introduce useful frameworks and tools. However, these are provided as an aid to your learning n

*1.3 Parallel and perpendicular lines Attempts to answer problems in areas as diverse as science, technology and economics involve solving simultaneous linear equations. In this unit we look at some of the equations that represent points, lines and planes in mathematics. We explore concepts such as Euclidean space, vectors, dot products and conics.*
