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…
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…
Zabbix was born as a distributed network monitoring tool with a central web interface where you can manage almost everything. Nowadays, with Zabbix 2.4, the number of possible architectures has been reduced to a single server setup and a Zabbix-proxies distributed setup.
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…
Graphene is a one-atom-thick and two-dimensional repetitive hexagonal lattice sp2-hybri‐ dized carbon layer. The extended honeycomb network of graphene is the basic building block of other important allotropes of carbon. 2D graphene can be wrapped to form 0D full‐ erenes, rolled to form 1D carbon nanotubes, and stacked to form 3D graphite. Depending on its unique structure, graphene yields …
The principles underlying modern approaches to securing information and systems that process information are well documented and well understood by practitioners. Modern techniques and technologies for implementing these principles are also well documented, and it is hard to find an area of information security that has not been the subject of a book or at least an article. However, most of the…
This book contains the joint proceedings of the workshop on Boundaries that took place in Graz, from June 29–July 3, and the Alp-Workshop that was held immediately afterwards in Sankt Kathrein am Offenegg, on the weekend July 4–5, 2009
