Book Description

Information Security Architecture, Second Edition incorporates the knowledge developed during the past decade that has pushed the information security life cycle from infancy to a more mature, understandable, and manageable state. It simplifies security by providing clear and organized methods and by guiding you to the most effective resources available.

In addition to the components of a successful Information Security Architecture (ISA) detailed in the previous edition, this volume also discusses computer incident/emergency response. The book describes in detail every one of the eight ISA components. Each chapter provides an understanding of the component and details how it relates to the other components of the architecture. The text also outlines how to establish an effective plan to implement each piece of the ISA within an organization.

The second edition has been modified to provide security novices with a primer on general security methods. It has also been expanded to provide veteran security professionals with an understanding of issues related to recent legislation, information assurance, and the latest technologies, vulnerabilities, and responses.
