Caught in the crosshairs of “Leadership” and “Information Technology”, Information Security professionals are increasingly tapped to operate as business executives. This often puts them on a career path they did not expect, in a field not yet clearly defined. IT training does not usually includemanagerial skills such as leadership, team-building, communication, risk assessment, and corporate business savvy, needed by CISOs. Yet a lack in any of these areas can short circuit a career in information security.

CISO Leadership: Essential Principles for Success captures years of hard knocks, success stories, and yes, failures. This is not a how-to book or a collection of technical data. It does not cover products or technology or provide a recapitulation of the common body of knowledge. The book delineates information needed by security leaders and includes from-the-trenches advice on how to have a successful career in the field.

With a stellar panel of contributors including William H. Murray, Harry Demaio, James Christiansen, Randy Sanovic, Mike Corby, Howard Schmidt, and other thought leaders, the book brings together the collective experience of trail blazers. The authors have learned through experience—been there, done that, have the t-shirt—and yes, the scars. A glance through the contents demonstrates the breadth and depth of coverage, not only in topics included but also in expertise provided by the chapter authors. They are the pioneers, who, while initially making it up as they went along, now provide the next generation of information security professionals with a guide to success.

In order to maximize IT resources and justify IT expenditures, CIO's and other IT managers must be able to identify meaningful metrics and explain them in a way that management can understand. The Business Value of IT: Managing Risks, Optimizing Performance, and Measuring Results solves this problem by providing practical answers to these questions: What does IT contribute to the business? Why should we care about IT governance? How can we best measure IT performance? How do we mitigate the risks associated with change? Leading consultants Michael D. Harris, David E. Herron, and Stasia Iwanicki share their real-world experiences to explain how you can demonstrate IT's value, and potentially find extra value you didn't know your IT organization creates. They also show how to apply risk management to process improvement and avoid unintended consequences of process improvement programs. The text provides the understanding required to discover the processes necessary to: prioritize your organization's IT activities. identify alternative measurement frameworks, and evaluate the best approaches to outsourcing. Many IT organizations have successfully implemented the techniques described in this book to increase their business value. This work identifies the organizational and cultural obstacles you need to remove to get started along the same path. "Whether you are inheriting a test team or starting one up, Manage Software Testing is a must-have resource that covers all aspects of test management. - It guides you through the business and organizational issues that you are confronted with each day, explaining what you need to focus on strategically, tactically, and operationally. - "Using a risk-based approach, the author addresses a range of questions about software product testing. - The book covers unit, system, and non-functional tests and includes examples of how to estimate the number of bugs expected to be found, the time required for testing, and the date when a release is ready. - It weighs the cost of finding bugs against the risks of missing release dates or letting bugs appear in the final released product. - "It is imperative to determine if bugs exist and then be able to assess how quickly they can be found, the cost of finding them (or not), and how many you can risk leaving in the product when it is released. - With this book, test managers can effectively and accurately establish these parameters."--Jacket

Whether you are inheriting a test team or starting one up, Manage Software Testing is a must-have resource that covers all aspects of test management. It guides you through the business and organizational issues that you are confronted with on a daily basis, explaining what you need to focus on strategically, tactically, and operationally.

Using a risk-based approach, the author addresses a range of questions about software product development. The book covers unit, system, and non-functional tests and includes examples on how to estimate the number of bugs expected to be found, the time required for testing, and the date when a release is ready. It weighs the cost of finding bugs against the risks of missing release dates or letting bugs appear in the final released product.

It is imperative to determine if bugs do exist and then be able to metric how quickly they can be identified, the cost they incur, and how many remain in the product when it is released. With this book, test managers can effectively and accurately establish these parameters.

Taking a broad approach that speaks to experienced and inexperienced process improvement practitioners, CMMI experts and CMMI novices, this second edition thoroughly examines the latest version of the CMMI. Divided into six sections, the text first clarifies the concept of process improvement, makes the case for how and why to employ CMMI, and outlines its structure. It then provides an overview of the process areas, supported by real-world display tables, templates, and charts designed to aid organizations in their improvement efforts. Subsequent sections address measurement issues including basic metrics, statistical process control, and high maturity concerns, as well as SCAMPISM appraisal types.

How do I measure IT performance? Is IT operating effectively? Where are we in relation to industry peers? How can we do IT better? How should we change? How can we manage IT changes? How should IT manage risk? How should IT manage its people? What should IT expect from the business?. The Business Value of IT: Managing Risks, Optimizing Performance, and Measuring Results examines how to measure IT performance, how to put a dollar value on IT, and how to justify value of an entire IT program.
