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.

Constraints

In the context of UML, Object Constraint Language (OCL) is often used to define preconditions and postconditions for operations (methods) of a class. Preconditions and postconditions specify the requirements that must be satisfied before and after an operation is invoked. They help ensure the operation’s behavior is well-defined and adheres to certain constraints. Here’s an explanation of preconditions and postconditions in OCL:

  • Preconditions:
    • Preconditions define conditions that must be true before an operation can be executed. They describe the state of the system or object that must be in place for the operation to proceed.
    • Preconditions are typically specified using OCL expressions and are associated with a specific operation in a UML class diagram. These expressions are evaluated before the operation is executed.
    • If a precondition is not satisfied when the operation is invoked, the system should prevent the operation from executing and report an...
