Description

Book Synopsis
Designing Secure Software consolidates Loren Kohnfelder's more than twenty years of experience into a concise, elegant guide to improving the security of technology products. Written for a wide range of software professionals, it emphasizes building security into software design early and involving the entire team in the process. The book begins with a discussion of core concepts. The second part, perhaps this book's most important contribution, covers the process of designing and reviewing a software design with security considerations in mind. The final section details the most common coding flaws that create vulnerabilities, making copious use of code snippets written in C and Python to illustrate implementation vulnerabilities.

Trade Review
"This book addresses software developers and designers, but it also has potential impact for those involved anywhere in the production of software. IT project managers in particular can benefit from this concept-heavy presentation because they need not wade into the waters of code."
—Scott J. Pearson, Blogger at scottjpearson.com

"Designing Secure Software creates a roadmap for building towards more secure software programs. Loren Kohnfelder draws upon technical knowledge gained and developed during his 20+ year career at Microsoft and Google to arm software engineers at any level with the security mindset and tools needed to create secure software. This book is comprehensive in scope and provides many excellent examples in python and C to aid in designing software securely."
—George D. Advanced Reviewer

"The authoritative introductory book on secure software design . . . I've learned so much while reading it."
—Kirill C., Advanced Reviewer

"Provides an in depth look on promoting secure software development and breaks down complex subjects into relatable examples. Contains methodologies that are helpful to remember in threat modeling and lessons to take from past software failures."
—Jessica W., Advanced Reviewer

"Very clear and easy reading, and the examples used are both captivating and easy to understand . . . A worthwhile read for both software developers and security engineers working the application security space. It distinguishes itself by focusing on concepts rather than being a checklist of individual items to focus on."
—System Overlord, SystemOverlord.com

"Technical books that read smoothly are rare, and this is one of them. The book provides a good overview of the application security field and gives you the resources to explore more."
—Vickie Li, Developer Evangelist, Author of Bug Bounty Bootcamp
