There are many ways that a potential attacker can intercept information, or learnmore about the sender, as the information travels over a network. Silence on the Wireuncovers these silent attacks so that system administrators can defend against them,as well as better understand and monitor their systems. Silence on the Wire dissects several unique and fascinating security andprivacy problems associated with the technologies and protocols used in everydaycomputing, and shows how to use this knowledge to learn more about others or tobetter defend systems. By taking an indepth look at modern computing, from hardwareon up, the book helps the system administrator to better understand security issues,and to approach networking from a new, more creative perspective. The sys admin canapply this knowledge to network monitoring, policy enforcement, evidence analysis,IDS, honeypots, firewalls, and forensics.

"Thorough and comprehensive coverage from one of the foremost experts in browser security." --Tavis Ormandy, Google Inc. Modern web applications are built on a tangle of technologies that have been developed over time and then haphazardly pieced together. Every piece of the web application stack, from HTTP requests to browser-side scripts, comes with important yet subtle security consequences. To keep users safe, it is essential for developers to confidently navigate this landscape. In The Tangled Web, Michal Zalewski, one of the world's top browser security experts, offers a compelling narrative that explains exactly how browsers work and why they're fundamentally insecure. Rather than dispense simplistic advice on vulnerabilities, Zalewski examines the entire browser security model, revealing weak points and providing crucial information for shoring up web application security. You'll learn how to: 
<ul>
<li>Perform common but surprisingly complex tasks such as URL parsing and HTML sanitization</li> <li>Use modern security features like Strict Transport Security, Content Security Policy, and Cross-Origin Resource Sharing</li> <li>Leverage many variants of the same-origin policy to safely compartmentalize complex web applications and protect user credentials in case of XSS bugs</li> <li>Build mashups and embed gadgets without getting stung by the tricky frame navigation policy</li> <li>Embed or host user-supplied content without running into the trap of content sniffing</li> </ul>For quick reference, "Security Engineering Cheat Sheets" at the end of each chapter offer ready solutions to problems you're most likely to encounter. With coverage extending as far as planned HTML5 features, The Tangled Web will help you create secure web applications that stand the test of time.

Disasters happen. Be prepared. Here's how. As a leading security engineer, Michal Zalewksi has spent his career methodically anticipating and planning for cyberattacks. In Practical Doomsday, Zalewski applies the same thoughtful, rational approach to preparing for disasters of all kinds. By sharing his research, advice, and a healthy dose of common sense, he'll help you rest easy knowing you have a plan for the worst-even if the worst never comes. The book outlines a level-headed model for evaluating risks, one that weighs the probability of scenarios against the cost of preparing for them. You'll learn to apply that model to the whole spectrum of potential crises, from personal hardships like job loss or a kitchen fire, to large-scale natural disasters and industrial accidents, to recurring pop-culture fears like all-out nuclear war. You'll then explore how basic lifestyle adjustments, such as maintaining a robust rainy-day fund, protecting yourself online, and fostering good relationships with your neighbors, can boost your readiness for a wide range of situations. You'll also take a no-nonsense look at the supplies and equipment essential to surviving sudden catastrophes, like prolonged power outages or devastating storms, and examine the merits and legal implications of different self-defense strategies. You'll learn- . How to identify and meaningfully assess risks in your life, then develop strategies for managing them . Ways to build up and diversify a robust financial safety net-a key component of nearly all effective preparedness strategies . How to adapt your prep plans to a variety of situations, from shelter-in-place scenarios to evacuations by car or on foot . Sensible approaches to stockpiling food, water, and other essentials, along with recommendations on what supplies are actually worth having Disasters happen, but they don't have to dominate your life. Practical Doomsday will help you plan ahead, so you can stop worrying about what tomorrow may bring and start enjoying your life today.
