Hands-On Security in DevOps

By: Tony Hsiang-Chih Hsu

Overview of this book

DevOps has provided speed and quality benefits with continuous development and deployment methods, but it does not guarantee the security of an entire organization. Hands-On Security in DevOps shows you how to adopt DevOps techniques to continuously improve your organization’s security at every level, rather than just focusing on protecting your infrastructure. This guide combines DevOps and security to help you to protect cloud services, and teaches you how to use techniques to integrate security directly in your product. You will learn how to implement security at every layer, such as for the web application, cloud infrastructure, communication, and the delivery pipeline layers. With the help of practical examples, you’ll explore the core security aspects, such as blocking attacks, fraud detection, cloud forensics, and incident response. In the concluding chapters, you will cover topics on extending DevOps security, such as risk assessment, threat modeling, and continuous security. By the end of this book, you will be well-versed in implementing security in all layers of your organization and be confident in monitoring and blocking attacks throughout your cloud services.

Secure compiling

Memory corruption and buffer overflow may result in exploit code injection attacks. For the C/C++ programming language, these can be protected by compiler options. By a properly secured configuration of a C/C++ compiler (GCC, MS Visual Studio), the application will be able to add an additional layer of runtime defenses against exploit code injection attacks. These are also mostly ignored by a development team. The common secure options are summarized in the following table:
