One the one hand, hackers infect the computers of the world, entering where they are not invited, taking over not just individual workstations but whole networks. On the other, hackers write the software that fuels the Internet, from the most popular web programmes to software fundamental to the Internet's existence. Beginning from an analysis of these two main types of hackers, categorised as crackers and Free Software/Open Source respectively, Tim Jordan gives the reader insight into the varied identities of hackers, including:
* Hacktivism; hackers and populist politics
* Cyberwar; hackers and the nation-state
* Digital Proletariat; hacking for the man
* Viruses; virtual life on the Internet
* Digital Commons; hacking without software
* Cypherpunks; encryption and digital security
* Nerds and Geeks; hacking cultures or hacking without the hack
* Cybercrime; blackest of black hat hacking
Hackers end debates over the meaning of technological determinism while recognising that at any one moment we are all always determined by technology. Hackers work constantly within determinations of their actions created by technologies as they also alter software to enable entirely new possibilities for and limits to action in the virtual world. Through this fascinating introduction to the people who create and recreate the digital media of the Internet, students, scholars and general readers will gain new insight into the meaning of technology and society when digital media are hacked.
One of the biggest buzzwords in the IT industry for the past few years, virtualization has matured into a practical requirement for many best-practice business scenarios, becoming an invaluable tool for security professionals at companies of every size. In addition to saving time and other resources, virtualization affords unprecedented means for intrusion and malware detection, prevention, recovery, and analysis. Taking a practical approach in a growing market underserved by books, this hands-on title is the first to combine in one place the most important and sought-after uses of virtualization for enhanced security, including sandboxing, disaster recovery and high availability, forensic analysis, and honeypotting.
Already gaining buzz and traction in actual usage at an impressive rate, Gartner research indicates that virtualization will be the most significant trend in IT infrastructure and operations over the next four years. A recent report by IT research firm IDC predicts the virtualization services market will grow from $5.5 billion in 2006 to $11.7 billion in 2011. With this growth in adoption, becoming increasingly common even for small and midsize businesses, security is becoming a much more serious concern, both in terms of how to secure virtualization and how virtualization can serve critical security objectives.
Titles exist and are on the way to fill the need for securing virtualization, but security professionals do not yet have a book outlining the many security applications of virtualization that will become increasingly important in their job requirements. This book is the first to fill that need, covering tactics such as isolating a virtual environment on the desktop for application testing, creating virtualized storage solutions for immediate disaster recovery and high availability across a network, migrating physical systems to virtual systems for analysis, and creating complete virtual systems to entice hackers and expose potential threats to actual production systems.
About the Technologies
A sandbox is an isolated environment created to run and test applications that might be a security risk. Recovering a compromised system is as easy as restarting the virtual machine to revert to the point before failure. Employing virtualization on actual production systems, rather than just test environments, yields similar benefits for disaster recovery and high availability. While traditional disaster recovery methods require time-consuming reinstallation of the operating system and applications before restoring data, backing up to a virtual machine makes the recovery process much easier, faster, and efficient. The virtual machine can be restored to same physical machine or an entirely different machine if the original machine has experienced irreparable hardware failure. Decreased downtime translates into higher availability of the system and increased productivity in the enterprise.
Virtualization has been used for years in the field of forensic analysis, but new tools, techniques, and automation capabilities are making it an increasingly important tool. By means of virtualization, an investigator can create an exact working copy of a physical computer on another machine, including hidden or encrypted partitions, without altering any data, allowing complete access for analysis. The investigator can also take a live ?snapshot? to review or freeze the target computer at any point in time, before an attacker has a chance to cover his tracks or inflict further damage.
A honeypot is a system that looks and acts like a production environment but is actually a monitored trap, deployed in a network with enough interesting data to attract hackers, but created to log their activity and keep them from causing damage to the actual production environment. A honeypot exposes new threats, tools, and techniques used by hackers before they can attack the real systems, which security managers patch based on the information gathered. Before virtualization became mainstream, setting up a machine or a whole network (a honeynet) for research purposes only was prohibitive in both cost and time management. Virtualization makes this technique more viable as a realistic approach for companies large and small.
* The first book to collect a comprehensive set of all virtualization security tools and strategies in a single volume
* Covers all major virtualization platforms, including market leader VMware, Xen, and Microsoft's Hyper-V virtualization platform, a new part of Windows Server 2008 releasing in June 2008
* Breadth of coverage appeals to a wide range of security professionals, including administrators, researchers, consultants, and forensic
“An amazing resource. It is timely, focused, and what we need to better understand and defend against one of the greatest cyber threats we face.” –From the Foreword by Lance Spitzner, President of the Honeynet Project
Don't let another machine become a zombie in the malware army
Defend against the ongoing wave of malware and rootkit assaults the failsafe Hacking Exposed way. Real-world case studies and examples reveal how today's hackers use readily available tools to infiltrate and hijack systems. Step-by-step countermeasures provide proven prevention techniques.

Identify and terminate malicious processes using HIPS and NIPS
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
