With continuous growth in the number of information objects and the
users that can access these objects, ensuring that access is
compliant with company policies has become a big challenge.
Role-based Access Control (RBAC) - a policy-neutral access control
model that serves as a bridge between academia and industry - is
probably the most suitable security model for commercial
applications.Interestingly, role design determines RBAC's cost.
When there are hundreds or thousands of users within an
organization, with individual functions and responsibilities to be
accurately reflected in terms of access permissions, only a
well-defined role engineering process allows for significant
savings of time and money while protecting data and systems.Among
role engineering approaches, searching through access control
systems to find de facto roles embedded in existing permissions is
attracting increasing interest. The focus falls on role mining,
which is applied data mining techniques to automate - to the extent
possible - the role design task.This book explores existing role
mining algorithms and offers insights into the automated role
design approaches proposed in the literature. Alongside theory,
this book acts as a practical guide for using role mining tools
when implementing RBAC. Besides a comprehensive survey of role
mining techniques deeply rooted in academic research, this book
also provides a summary of the role-based approach, access control
concepts and describes a typical role engineering process.Among the
pioneering works on role mining, this book blends business elements
with data mining theory, and thus further extends the applications
of role mining into business practice. This makes it a useful guide
for all academics, IT and business professionals.
