Facebook, Twitter, and LinkedIn generate a tremendous amount of valuable social data, but how can you find out who’s making connections with social media, what they’re talking about, or where they’re located? This concise and practical book shows you how to answer these questions and more. You’ll learn how to combine social web data, analysis techniques, and visualization to help you find what you’ve been looking for in the social haystack, as well as useful information you didn’t know existed.
Each standalone chapter introduces techniques for mining data in different areas of the social Web, including blogs and email. All you need to get started is a programming background and a willingness to learn basic Python tools.

“Let Matthew Russell serve as your guide to working with social data sets old (email, blogs) and new (Twitter, LinkedIn, Facebook). Mining the Social Web is a natural successor to Programming Collective Intelligence: a practical, hands-on approach to hacking on data from the social Web with Python.”
–Jeff Hammerbacher, Chief Scientist, Cloudera
“A rich, compact, useful, practical introduction to a galaxy of tools, techniques, and theories for exploring structured and unstructured data.”
The worldwide reach of the Internet allows malicious cyber criminals to coordinate and launch attacks on both cyber and cyber-physical infrastructure from anywhere in the world. This purpose of this handbook is to introduce the theoretical foundations and practical solution techniques for securing critical cyber and physical infrastructures as well as their underlying computing and communication architectures and systems. Examples of such infrastructures include utility networks (e.g., electrical power grids), ground transportation systems (automotives, roads, bridges and tunnels), airports and air traffic control systems, wired and wireless communication and sensor networks, systems for storing and distributing water and food supplies, medical and healthcare delivery systems, as well as financial, banking and commercial transaction assets. The handbook focus mostly on the scientific foundations and engineering techniques – while also addressing the proper integration of policies and access control mechanisms, for example, how human-developed policies can be properly enforced by an automated system.
*Addresses the technical challenges facing design of secure infrastructures by providing examples of problems and solutions from a wide variety of internal and external attack scenarios
*Includes contributions from leading researchers and practitioners in relevant application areas such as smart power grid, intelligent transportation systems, healthcare industry and so on.
*Loaded with examples of real world problems and pathways to solutions utilizing specific tools and techniques described in detail throughout
If you’re an app developer with a solid foundation in Objective-C, this book is an absolute must—chances are very high that your company’s iOS applications are vulnerable to attack. That’s because malicious attackers now use an arsenal of tools to reverse-engineer, trace, and manipulate applications in ways that most programmers aren’t aware of.
This guide illustrates several types of iOS attacks, as well as the tools and techniques that hackers use. You’ll learn best practices to help protect your applications, and discover how important it is to understand and strategize like your adversary.
Examine subtle vulnerabilities in real-world applications—and avoid the same problems in your apps
Learn how attackers infect apps with malware through code injection
Discover how attackers defeat iOS keychain and data-protection encryption
Use a debugger and custom code injection to manipulate the runtime Objective-C environment
Prevent attackers from hijacking SSL sessions and stealing traffic
Securely delete files and design your apps to prevent forensic data leakage
Avoid debugging abuse, validate the integrity of run-time classes, and make your code harder to trace
