The Tangled Web
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: –Perform common but surprisingly complex tasks such as URL parsing and HTML sanitization –Use modern security features like Strict Transport Security, Content Security Policy, and Cross-Origin Resource Sharing –Leverage many variants of the same-origin policy to safely compartmentalize complex web applications and protect user credentials in case of XSS bugs –Build mashups and embed gadgets without getting stung by the tricky frame navigation policy –Embed or host user-supplied content without running into the trap of content sniffing 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.
Tangled Webs
Bestselling author James B. Stewart's newsbreaking investigation of our era's most high-profile perjurers, revealing the alarming extent of this national epidemic. Our system of justice rests on a simple proposition: that witnesses will raise their hands and tell the truth. In Tangled Webs, James B. Stewart reveals in vivid detail the consequences of the perjury epidemic that has swept our country, undermining the very foundation of our courts. With many prosecutors, investigators, and participants speaking for the first time, Tangled Webs goes behind the scene of the trials of media and homemaking entrepreneur Martha Stewart; top White House political adviser Lewis "Scooter" Libby; home-run king Barry Bonds; and Wall Street money manager Bernard Madoff. The saga of Martha Stewart's conviction captured the nation, but until now no one has answered the most basic question: Why would Stewart risk prison, put her entire empire in jeopardy, and lie repeatedly to government investigators to save a few hundred thousand dollars in stock gains? Moreover, how exactly was the notoriously meticulous Stewart brought down? Drawing on the accounts of then-deputy attorney general James Comey and U.S. Attorney Patrick Fitzgerald, Stewart sheds new light on the Libby investigation, making clear how far into the White House the Valerie Plame CIA scandal extended, and why Libby took the fall. In San Francisco, Giants home-run king Barry Bonds faces trial due to his testimony before a grand jury investigating the use of illegal steroids in sports. Bonds was warned explicitly that the only crime he faced was perjury. Stewart unlocks the story behind the mounting evidence that he nonetheless lied under oath. Bernie Madoff's Ponzi scheme is infamous, but less well known is how he eluded detection for so long in the face of repeated investigations. Of the four he is the only one who has admitted to lying. The perjury outbreak is symptomatic of a broader breakdown of ethics in American life. It isn't just the judicial system that relies on an honor code: Academia, business, medicine, and government all depend on it. Tangled Webs explores the age-old tensions between greed and justice, self-interest and public interest, loyalty and duty. At a time when Americans seem hungry for moral leadership and clarity, Tangled Webs reaffirms the importance of truth.
A Tangled Web
In the tradition of her acclaimed mother, Ann Rule, author of The Stranger Beside Me, bestselling author Leslie Rule exposes the trail of a sadistic sociopath, identity thief, and killer . . . It was a bleak November in 2012 when Cari Farver, thirty-seven, vanished from Omaha, Nebraska. Texts sent indicated that the hardworking mother had quit her job, abandoned her son, and cut ties with everyone. Cari’s boyfriend, Dave Kroupa, accepted the breakup at face value. Her mother, Nancy Raney, however, had doubts. “I need to hear your voice,” Nancy begged. When the texter refused to speak, Nancy reported Cari missing. While no one saw or spoke to Cari, more than 12,000 sinister emails and texts were sent in her name over the next years. Police believed Dave and his girlfriend, Shanna “Liz” Golyar, when they reported that the missing woman was cyberstalking them. The tormentor was eerily aware of Dave’s every move, knew when Liz visited and threatened the couple. It never occurred to Dave that Cari was a victim—that the real stalker had killed before, and was planning to kill again. Leslie Rule tracks the heart-pounding path to long-awaited justice—from a twisted past to the deadly deception and the high-tech forensics that condemned the killer to prison. “Rule's first true crime book hits the mark.” —Katherine Ramsland, author of Confession of a Serial Killer: The Untold Story of Dennis Rader the BTK Killer “A deft, fascinating true crime story of obsession.” —Library Journal (Starred Review) With a New Update by the Author Includes Reading Group Guide
