Software Architecture with Python

By: Anand Balachandran Pillai

Overview of this book

This book starts by explaining how Python fits into an application's architecture. As you move along, you will get to grips with architecturally significant demands and how to determine them. Later, you’ll gain a complete understanding of the different architectural quality requirements for building a product that satisfies business needs, such as maintainability/reusability, testability, scalability, performance, usability, and security. You will also use various techniques such as incorporating DevOps, continuous integration, and more to make your application robust. You will discover when and when not to use object orientation in your applications, and design scalable applications. The focus is on building the business logic based on the business process documentation, and understanding which frameworks to use and when to use them. The book also covers some important patterns that should be taken into account while solving design problems, as well as those in relatively new domains such as the Cloud. By the end of this book, you will have understood the ins and outs of Python so that you can make critical design decisions that not just live up to but also surpassyour clients’ expectations.

Summary


In this chapter, we started with looking at the details of a system architecture that builds in security. We went on to define secure coding, and looked at the philosophies and principles behind the practice of secure coding.

We then studied the different types of common security vulnerabilities encountered in software systems, such as buffer overflows, input validation issues, access control issues, cryptographic weaknesses, information leaks, insecure file operations, and so on.

We then went on to a detailed discussion on Python security issues with a lot of examples. We looked in detail at reading and evaluating input, overflow errors, and serialization issues. We then went on to look at the common vulnerabilities in Python web application frameworks with Flask being the candidate of choice. We saw how one can exploit the weaknesses on web application templates, and perform attacks such as SSTI, XSS, and DOS. We also saw multiple code examples of how to mitigate these attacks.
