Security-Driven Software Development

By: Aspen Olmsted

Overview of this book

Extend your software development skills to integrate security into every aspect of your projects. Perfect for any programmer or developer working on mission-critical applications, this hands-on guide helps you adopt secure software development practices. Explore core concepts like security specifi cation, modeling, and threat mitigation with the iterative approach of this book that allows you to trace security requirements through each phase of software development. You won’t stop at the basics; you’ll delve into multiple-layer att acks and develop the mindset to prevent them. Through an example application project involving an entertainment ticketing software system, you’ll look at high-profi le security incidents that have aff ected popular music stars and performers. Drawing from the author’s decades of experience building secure applications in this domain, this book off ers comprehensive techniques where problem-solving meets practicality for secure development. By the end of this book, you’ll have gained the expertise to systematically secure software projects, from crafting robust security specifi cations to adeptly mitigating multifaceted threats, ensuring your applications stand resilient in the face of evolving cybersecurity challenges.

Partitions

Partitions in a system model, often called system partitions or system decomposition, involve breaking down a complex system into smaller, more manageable components or subsystems. These partitions help understand, design, and organize a system’s architecture. Partition boundaries are also where most software security risks exist because the boundary naturally has data passing across it to get to the next partition in the architecture. In this chapter, we will explore different architectural styles that utilize the partitions differently.

Here’s how partitions are typically used in a system model:

  • Divide and conquer: Partitioning allows you to divide a complex system into smaller, self-contained parts. Each partition or subsystem can be designed, developed, and tested independently, making it easier to manage the system as a whole.
  • Separation of concerns: Partitioning enables the separation of different concerns or aspects of the system. For...
