Book cover art

Designing Secure Software consolidates 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, covering trust, threats, mitigation, secure design patterns, and cryptography. The second part, perhaps this book’s most unique and important contribution to the field, 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.

You’ll learn how to:

  • Identify important assets, the attack surface, and the trust boundaries in a system
  • Evaluate the effectiveness of various threat mitigation candidates
  • Work with well-known mitigations and secure design patterns
  • Understand and prevent vulnerabilities like XSS and CSRF, memory flaws, and more
  • Use security testing to proactively identify vulnerabilities introduced into code
  • Review a software design for security flaws effectively and without judgment

Copy edit of a chapter

Copy edit is the last chance to make significant changes to the text. Most chapters involve plenty of sentence rewriting and a few moves of a paragraph, but much of the delta is punctuation and word choice. [Read More]

Artwork ready for review

The artwork came back as a PDF with one drawing per page, labeled by filename. The first batch was pretty good, considering that Richard (I learned the artist’s name) must have had no idea what the symbols meant. [Read More]

Copy edit begins

Copy edit phase starts this week with two chapters (Ch 1 and 4). The chapters that resulted from developmental editing have been converted to a new style regime, and are now ODT instead of DOCX format. [Read More]

Artwork help needed

Perhaps it was due to poor grades in Art class back in my school days, but I quickly realized that the sketches I did for graphics in the book we not going to be up to par. [Read More]
