Identify tools and techniques to secure and perform a penetration test on an AWS infrastructure using Kali Linux Key Features * Efficiently perform penetration testing techniques on your public cloud instances * Learn not only to cover loopholes but also to automate security monitoring and alerting within your cloud-based deployment pipelines * A step-by-step guide that will help you leverage the most widely used security platform to secure your AWS Cloud environment Book Description The cloud is taking over the IT industry. Any organization housing a large amount of data or a large infrastructure has started moving cloud-ward — and AWS rules the roost when it comes to cloud service providers, with its closest competitor having less than half of its market share. This highlights the importance of security on the cloud, especially on AWS. While a lot has been said (and written) about how cloud environments can be secured, performing external security assessments in the form of pentests on AWS is still seen as a dark art. This book aims to help pentesters as well as seasoned system administrators with a hands-on approach to pentesting the various cloud services provided by Amazon through AWS using Kali Linux. To make things easier for novice pentesters, the book focuses on building a practice lab and refining penetration testing with Kali Linux on the cloud. This is helpful not only for beginners but also for pentesters who want to set up a pentesting environment in their private cloud, using Kali Linux to perform a white-box assessment of their own cloud resources. Besides this, there is a lot of in-depth coverage of the large variety of AWS services that are often overlooked during a pentest — from serverless infrastructure to automated deployment pipelines. By the end of this book, you will be able to identify possible vulnerable areas efficiently and secure your AWS cloud environment. What you will learn * Familiarize yourself with and pentest the most common external-facing AWS services * Audit your own infrastructure and identify flaws, weaknesses, and loopholes * Demonstrate the process of lateral and vertical movement through a partially compromised AWS account * Maintain stealth and persistence within a compromised AWS account * Master a hands-on approach to pentesting * Discover a number of automated tools to ease the process of continuously assessing and improving the security stance of an AWS infrastructure Who this book is for If you are a security analyst or a penetration tester and are interested in exploiting Cloud environments to reveal vulnerable areas and secure them, then this book is for you. A basic understanding of penetration testing, cloud computing, and its security concepts is mandatory.

One of the most lauded historians of our time returns to the Second World War in this magnificent retelling of the awe-inspiring raid on German dams conducted by the Royal Army Force’s 617 Squadron.The attack on Nazi Germany’s dams on May 17, 1943, was one of the most remarkable feats in military history. The absurdly young men of the Royal Air Force’s 617 Squadron set forth in cold blood and darkness, without benefit of electronic aids, to fly lumbering heavy bombers straight and level towards a target at a height above the water less than the length of a bowling alley. Yet this story—and the later wartime experience of the 617 Squadron—has never been told in full. Max Hastings takes us back to the May 1943 raid to reveal how the truth of that night is considerably different from the popularized account most people know. The RAF had identified the Ruhr dams as strategic objectives as far back as 1938; in those five years Wing Commander Guy Gibson formed and trained the 617 Squadron. Hastings observes that while the dropping of Wallis’s mines provided the dramatic climax, only two of the eight aircraft lost came down over the dams—the rest were shot down on the flight to, or back from, the mission. And while the 617 Squadron’s valor is indisputable, the ultimate industrial damage caused by the dam raid was actually rather modest. In 1943, these brave men caught the imagination of the world and uplifted the weary spirits of the British people. Their achievement unnerved the Nazi high command, and caused them to expend large resources on dam defenses—making the mission a success. An example of Churchill’s “military theatre” at its best, what 617 Squadron did was an extraordinary and heroic achievement, and a triumph of British ingenuity and technology—a story to be told for generations to come.Operation Chastise includes three 8-page black-and-white photo inserts and 6 maps.

Mezrich shares his gratitude and awe for the privilege of being part of this transformative exchange as the dead give their last breath of life to the living. After all, the donors are his patients, too.When Death Becomes Life also engages in fascinating ethical and philosophical debates: How much risk should a healthy person be allowed to take to save someone she loves? Should a patient suffering from alcoholism receive a healthy liver? What defines death, and what role did organ transplantation play in that definition?
