Enterprise Level Security: Securing Information Systems in an
Uncertain World provides a modern alternative to the fortress
approach to security. The new approach is more distributed and has
no need for passwords or accounts. Global attacks become much more
difficult, and losses are localized, should they occur. The
security approach is derived from a set of tenets that form the
basic security model requirements. Many of the changes in
authorization within the enterprise model happen automatically.
Identities and claims for access occur during each step of the
computing process. Many of the techniques in this book have been
piloted. These techniques have been proven to be resilient, secure,
extensible, and scalable. The operational model of a distributed
computer environment defense is currently being implemented on a
broad scale for a particular enterprise. The first section of the
book comprises seven chapters that cover basics and philosophy,
including discussions on identity, attributes, access and
privilege, cryptography, the cloud, and the network. These chapters
contain an evolved set of principles and philosophies that were not
apparent at the beginning of the project. The second section,
consisting of chapters eight through twenty-two, contains technical
information and details obtained by making painful mistakes and
reworking processes until a workable formulation was derived.
Topics covered in this section include claims-based authentication,
credentials for access claims, claims creation, invoking an
application, cascading authorization, federation, and content
access control. This section also covers delegation, the enterprise
attribute ecosystem, database access, building enterprise software,
vulnerability analyses, the enterprise support desk, and network
defense.
