AWS Penetration Testing

By: Jonathan Helmus

Overview of this book

Cloud security has always been treated as the highest priority by AWS while designing a robust cloud infrastructure. AWS has now extended its support to allow users and security experts to perform penetration tests on its environment. This has not only revealed a number of loopholes and brought vulnerable points in their existing system to the fore, but has also opened up opportunities for organizations to build a secure cloud environment. This book teaches you how to perform penetration tests in a controlled AWS environment. You'll begin by performing security assessments of major AWS resources such as Amazon EC2 instances, Amazon S3, Amazon API Gateway, and AWS Lambda. Throughout the course of this book, you'll also learn about specific tests such as exploiting applications, testing permissions flaws, and discovering weak policies. Moving on, you'll discover how to establish private-cloud access through backdoor Lambda functions. As you advance, you'll explore the no-go areas where users can’t make changes due to vendor restrictions and find out how you can avoid being flagged to AWS in these cases. Finally, this book will take you through tips and tricks for securing your cloud environment in a professional way. By the end of this penetration testing book, you'll have become well-versed in a variety of ethical hacking techniques for securing your AWS environment against modern cyber threats.

S3 Burp Suite extensions

Burp Suite is a tool commonly used for web application testing. We aren't going to get deep into the details of how Burp Suite works, however, please stop by the PortSwigger website for more details:

With an enormous amount of available extensions, Burp is becoming more and more widely used by pentesters and application security engineers – and now can be used by cloud security professionals to test their environments. We are going to take a look at an extension called aws-extender. The extension allows you to scan for misconfigurations in S3 buckets.

Before we begin, we need to ensure we have the most up-to-date Python package installed.
