Global Security Week (GSW)

For more details on the (GSW) see:

And here is a description from one the organizers:

The aim of Global Security Week is to raise security awareness amongst the public and organizations about issues relating to security, primarily information security. This year's theme is on the subject of privacy and we hope that a number of events will be held worldwide to promote people's awareness as to how to protect their privacy when online and also educate companies on their responsibilities, both legal and morally, when it comes to protecting the privacy of their customers. Global Security Week is a totally voluntary initiative and we have no commercial funding or agenda. The initiative is funded entirely from the committee's own funds and time. We have people involved in Global Security Week throughout the world and during the week we have events planned in different regions. For example here in Ireland I plan to run a free seminar on the above topic open to anyone who wished to attend

We ask that those who wish to become involved, help promote Global Security Week in their region either by running specific events dedicated to Global Security Week, taking part in events already planned or simply making people aware that the week is on and the topic is "Privacy in the 21st Century". Even simply making people aware of Global Security Week and directing them to the website is a great help. Not having commercial funding we depend on word of mouth and like minded individuals to make people aware of the week.

1. Significance of Random Numbers in Application Security: Richard Lewis, e-Security Consultant with Tech Mahindra, started with the practical usage of random numbers. He explained how good random number generation prevents applications from malfunctioning, increases strength of cryptographic operations which in turn increases entropy associated with the key. He went on to explain how random numbers automate otherwise manual tasks and how it increases the security of application. He explained the concepts of entropy and to which level it should be reached in an application. In the end he talked about the various sources of random numbers. He showed developers the simple mathematics required to calculate minimum password lengths, given the security requirements.
