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.

Login protection

Login protection can be seen as the first defense layer of the application. Hackers may use tools or APIs to do brute-force login attacks. CAPTCHA is one of the approaches to distinguishing human from machine input. A CAPTCHA requires the client to complete visual-perception tasks. However, the CAPTCHA may be defeated by OCR or unwitting human labor. In addition to CAPTCHA, we can also have another layer of security defense to monitor the number of login failures. If the number of login failures reaches a certain threshold level, the system should take action, such as banning the IP source:

Tools/modules for login protection are summarized in the table:
