The IP version currently used in networks and the Internet is IP version 4 (IPv4). IPv4 was developed in the early ’70s to facilitate communication and information sharing between government researchers and academics in the United States. At the time, the system was closed with a limited number of access points, and consequently the devel‐ opers didn’t envision requirements such as securi…
The Windows 8 operating system is the newest member of the Microsoft Windows family. It differs from earlier Windows releases as much for what it does not change as for what it does change. That is, the features that IT pros loved about Windows 7 are still there in Windows 8—just better. The same keyboard shortcuts, management tools, security features, and deployment options are available in …
Next generation supercomputers require drastically better energy efficiency to allow these systems to scale to exaflop computing levels.Virtually all major processor ven- dors and companies such asAMD, Intel, and IBM are developing high-performance and highly energy-efficient multicore processors and dedicating their current and future development and manufacturing to multicore products. It …
Since the first edition of Hacking Exposed Wireless, the technologies and the threats facing these communications have grown in number and sophistication. Combined with the rapidly increasing number of deployments the risk of implementing wireless technologies has been compounded. Nevertheless, the risk is often surpassed by the benefits and convenience of wireless technologies, which have been…
Data is the most important resource that any business owns. It’s literally possible to replace any part of a business except the data. When the data is modified, corrupted, stolen, or deleted, a business can suffer serious loss. In fact, a business that has enough go wrong with its data can simply cease to exist. The focus of security, therefore, is not hackers, applications, networks, or any…
Security is arguably one of the most critical architectural components of any web-based application written in the 21st century. In an era where malware, criminals, and rogue employees are always present and actively testing software for exploits, smart and comprehensive use of security is a key element to any project for which you'll be responsible. This book is written to follow a pattern o…
This chapter introduces the principles of network security monitoring (NSM), which is the collection, analysis, and escalation of indications and warnings to detect and respond to intrusions. NSM is a way to find intruders on your network and do something about them before they damage your enterprise.
Many of us test web applications on either a daily or regular basis. We may be following a script of interactions (“click here, type XYZ, click Submit, check for OK message…”) or we might be writing frameworks that invoke batteries of automated tests against our web applications. Most of us are somewhere in between. Regardless of how we test, we need to get security testing into what we…
For many years Microsoft has maintained two sets of operating systems that both used the Windows name. From Windows 95 and 98 to Windows Me, an inexpensive operating system that could be used for both home and business applications was produced. For the server and workstation market, Microsoft produced Windows NT and Windows 2000. But maintaining two different operating system kernels for these…
Wireless networks and security might be considered an oxymoron. Indeed it is hard to believe in security when it is so easy to access communication media such as wireless radio media. However, the research community in industry and academia has for many years extended wired security mechanisms or developed new security mechanisms and security protocols to sustain this marriage between wireless/…
Wireshark is perhaps the world's most popular network packet analyzer used to troubleshoot and analyze network and application protocols across wide variety of technologies. Wireshark is free, open source, and available for Windows, Mac OS X, Linux, and several Unix-like platforms, and it is continuously being improved and expanded by its original developer, Gerald Combs, and over 500 code cont…
The first edition of this book appeared eight years ago. Since then the banking industry experienced a lot of change and challenges. The most recent financial crisis which started around May 2007 and lasted in its core period until early 2009 gave rise to a lot of scepticism about whether credit risk models are appropriate to capture the true nature of risks inherent in credit portfolios in gen…
