By day, Angie, a twenty-year veteran of the tech industry, is a data analyst at Tomo, the world's largest social networking company; by night, she exploits her database access to profile domestic abusers and kill the worst of them. She can't change her own traumatic past, but she can save other women. When Tomo introduces a deceptive new product that preys on users’ fears to drive up its own revenue, Angie sees Tomo for what it really is—another evil abuser. Using her coding and hacking expertise, she decides to destroy Tomo by building a new social network that is completely distributed, compartmentalized, and unstoppable. If she succeeds, it will be the end of all centralized power in the Internet. But how can an anti-social, one-armed programmer with too many dark secrets succeed when the world’s largest tech company is out to crush her and a no-name government black ops agency sets a psychopath to look into her growing digital footprint? “Awesome, thrilling, and creepy: a fast-paced portrayal of the startup world, and the perils of our personal data and technical infrastructure in the wrong hands.” —Brad Feld, managing director of Foundry Group “His most ambitious work yet. A murder thriller about high tech surveillance and espionage in the startup world. Like the best of Tom Clancy and Barry Eisner.” —Gene Kim, author of The Phoenix Project “Explores the creation and effects of the templated self, the rise of structured identity and one-size-fits-all media culture, and feasible alternatives.” —Amber Case, author of Calm Technology

Computer security is an ongoing process, a relentless contest between system administrators and intruders. A good administrator needs to stay one step ahead of any adversaries, which often involves a continuing process of education. If you're grounded in the basics of security, however, you won't necessarily want a complete treatise on the subject each time you pick up a book. Sometimes you want to get straight to the point. That's exactly what the new Linux Security Cookbook does. Rather than provide a total security solution for Linux computers, the authors present a series of easy-to-follow recipes--short, focused pieces of code that administrators can use to improve security and perform common tasks securely.The Linux Security Cookbook includes real solutions to a wide range of targeted problems, such as sending encrypted email within Emacs, restricting access to network services at particular times of day, firewalling a webserver, preventing IP spoofing, setting up key-based SSH authentication, and much more. With over 150 ready-to-use scripts and configuration files, this unique book helps administrators secure their systems without having to look up specific syntax. The book begins with recipes devised to establish a secure system, then moves on to secure day-to-day practices, and concludes with techniques to help your system stay secure.Some of the "recipes" you'll find in this book are: Controlling access to your system from firewalls down to individual services, using iptables, ipchains, xinetd, inetd, and more Monitoring your network with tcpdump, dsniff, netstat, and other tools Protecting network connections with Secure Shell (SSH) and stunnel Safeguarding email sessions with Secure Sockets Layer (SSL) Encrypting files and email messages with GnuPG Probing your own security with password crackers, nmap, and handy scripts This cookbook's proven techniques are derived from hard-won experience. Whether you're responsible for security on a home Linux system or for a large corporation, or somewhere in between, you'll find valuable, to-the-point, practical recipes for dealing with everyday security issues. This book is a system saver.
