SCADA Syndrome and Lifelong Education
How many times have we encountered a situation where some part of the software industry starts small, in a closed environment, then grows and attracts a lot of attention before realising that things were not designed properly for this changed environment? On a large scale, I would say three times. It happened with the Internet, operating systems, and system and industrial control systems (also referred to as SCADA). This transition from a closed environment to an open environment inevitably exposes aspects that were overlooked during the development phase. The speed of this transition will only exacerbate the situation. Because SCADA systems are currently going through this transition I will call this a "SCADA Syndrome."

Online Shopping: A Classic Case of Convenience vs Security
It is certainly a new day and age for many aspects of today’s society. One prominent sector that continues to lead by example in this area is the Internet, more specifically the online shopping environment. Note that online shopping is not a simple matter of go to a website, click “buy,” and checkout. That would be too simple. Ironically the purchase aspect itself tends to be the simplest matter here. The crux of the experience begins with the search and research phase. What exactly does one need/want? Is there a particular brand in mind? Is there a popular alternative? The convenience of asking and gathering answers to these questions and many more begin the journey, and thanks to the power and slew of resources the Internet provides, shoppers are able to search common products, brands, uses, verify details such as durability, ease of use and more based on the numerous rating systems, applications, web 2.0 solutions, social networking, and the ongoing phenomena that continue to evolve. So what does this mean? What does this have to do with security?

Social Security Number Sharing: Is Your Social Security Number “Yours”?
It's happening every day. People are inadvertently sharing one of the most personal and private pieces of information, the infamous social security number (SSN). For Jonathan Barnett, the unbelievable became a reality when he discovered that nearly 50 names were connected to his SSN. The irony is that his credit report and social security earnings records are clean. The nation's creditors, employers, and many others depend on this identity system predicated on SSNs.
