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…
Security is arguably one of the most critical architectural components of any web-based application written in the 21st century.

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.
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/…
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…
It's Friday night, and you are at a party outside the city with old friends. After a few beers it looks like this is going to be a great party, when suddenly your phone rings. A customer can't access some critical server that absolutely has to be available as soon as possible. You try to ssh in the server, only to discover that customer is right—it can't be accessed. As driving after those fe…
Whether it's internal or public-facing technology, businesses of all sizes depend on the availability of their IT assets, which may include servers, routers, networks, switches, and websites. If you're picking up this book, then you already know the value of monitoring and more than likely have an installation of Zenoss Core running. Zenoss Core is an open source network and system monitoring …
If you have ever arrived at work to answer voice mails and emails about a down web server, print server, or mail server, then you must be familiar with the customer-driven monitoring solution. It's cheap to implement but unreliable, and sometimes the monitor gets an attitude and for good reason. Our customers should not bear the responsibility of monitoring our networks for problems. Unfortun…
