Preface

As global networks expand the interconnection of the world’s technically complex infra- structure, communication and computing systems gain added importance. Information secu- rity has gained in importance as a professional practice, and information security has emerged as an academic discipline. Recent events, such as malware attacks and successful hacking efforts, have pointed out the weaknesses inherent in unprotected systems and exposed the need for heightened security of these systems. In order to secure technologically advanced systems and networks, both education and the infrastructure to deliver that educa- tion are needed to prepare the next generation of information technology and information security professionals to develop a more secure and ethical computing environment. There- fore, improved tools and more sophisticated techniques are needed to prepare students to recognize the threats and vulnerabilities present in existing systems and to design and develop the secure systems needed in the near future. Many years have passed since the need for improved information security education has been recognized, and as Dr. Ernest McDuffie of NIST points out:

While there is no doubt that technology has changed the way we live, work, and play, there are very real threats associated with the increased use of technology and our growing dependence on cyberspace….

Education can prepare the general public to identify and avoid risks in cyber- space; education will ready the cybersecurity workforce of tomorrow; and

education can keep today’s cybersecurity professionals at the leading edge of the latest technology and mitigation strategies.

The need for improvements in information security education is so great that the U.S. National Secu- rity Agency (NSA) has established Centers of Academic Excellence in Information Assurance, as described in Presidential Decision Directive 63, “The Policy on Critical Infrastructure Protection,” May 1998:

The program goal is to reduce vulnerabilities in our National Information Infrastructure by promoting higher education in information assurance, and producing a growing num- ber of professionals with IA expertise in various disciplines.

The technical nature of the dominant texts on the market does not meet the needs of students who have a major other than computer science, computer engineering, or electronic engineering. This is a key concern for academics who wish to focus on delivering skilled undergraduates to the commer- cial information technology (IT) sector. Specifically, there is a clear need for information security, information systems, criminal justice, political science, and accounting information systems students to gain a clear understanding of the foundations of information security.

Approach This book provides an overview of contingency operations and its components as well as a thorough treatment of the administration of the planning process for incident response, disaster recovery, and business continuity. It can be used to support course delivery for information-security-driven programs targeted at information technology students, as well as IT management and technology management curricula aimed at business or technical management students.

Learning Support—Each chapter includes a Chapter Summary and a set of open-ended Review Questions. These are used to reinforce learning of the subject matter presented in the chapter.

Chapter Scenarios—Each chapter opens and closes with a case scenario that follows the same fic- tional company as it encounters various contingency planning or operational issues. The closing sce- nario also includes a few discussion questions. These questions give the student and the instructor an opportunity to discuss the issues that underlie the content.

Hands-On Learning—At the end of each chapter, Real-World Exercises and Hands-On Projects are provided. These give students the opportunity to examine the contingency planning arena outside the classroom. Using these exercises, students can pursue the learning objectives listed at the begin- ning of each chapter and deepen their understanding of the text material.

Boxed Examples—These supplemental sections, which feature examples not associated with the ongoing case study, are included to illustrate key learning objectives or extend the coverage of plans and policies.

New to This Edition This edition provides a greater level of detail than the previous edition, specifically in the examination of incident response activities. It incorporates new approaches and methods that have been developed at NIST. Although the material on disaster recovery, business continuity, and crisis management has not

been reduced, the text’s focus now follows that of the IT industry in shifting to the prevention, detection, reaction to, and recovery from computer-based incidents and avoidance of threats to the security of infor- mation. We are fortunate to have had the assistance of a reviewer who worked as a contributing author for NIST, ensuring alignment between this text and the methods recommended by NIST.

Author Team Long-time college professors and information security professionals Michael Whitman and Herbert Mattord have jointly developed this text to merge knowledge from the world of academic study with practical experience from the business world. Professor Andrew Green has been added to this proven team to add a new dimension of practical experience.
