The Israeli department of defence has one of the strictest information security guidelines in the world, and a part of these guidelines is the requirement to have complete physical separation between the public and internal networks. A regular firewall just won't do, and this requirement gave birth to the concept of the
Air-Gap, a revolutionary product for its time. The Air-Gap and e-Gap products
used a physical switch that enabled the transfer of data from one network to the other, but still kept them physically disconnected. One might think of this like a shuttle transferring passengers from one land-mass to another. Whether this is more secure than advanced software-based firewalls can be debated, but the product did meet the guidelines and became very successful in Israel.
Building on this success, Whale Communications distributed the e-Gap appliance throughout the world, and continued its development. In 2006, Whale Communications was purchased by Microsoft, and the next version, named Intelligent Application Gateway or IAG, had similar capabilities, but ditched the physical switch and the dual-server design with a software firewall—Microsoft's ISA 2006 server.
Computational Intelligence in Control
The problem of controlling uncertain dynamic systems, which are subject to external disturbances, uncertainty and sheer complexity is of considerable interest in computer science, Operations Research and Business domains. The application of intelligent systems has been found useful in problems when the process is either difficult to model or...
Data Mining : Concepts, Models, Methods, and Algorithms
We are surrounded by data, numerical and otherwise, which must be analyzed and processed to convert it into information that informs, instructs, answers, or otherwise aids understanding and decision-making. Due to the ever-increasing complexity and size of today’s data sets, a new term, data mining, was created to describe the...
HbA1c in Diabetes: Case studies using IFCC units
The measurement of HbA1c is a key tool in the treatment of diabetes mellitus. For health care professionals involved in the management of diabetes in the UK there is an additional complication, between 2009 and 2011, with a change of HbA1c units. The old DCCT percentage is giving way to the internationally recognised IFCC units of mmol/mol in...
