title: From reactionary to proactive security: context-aware security policy management and optimization under uncertainty

authors: Chaisiri, Sivadon

subjects: computer science

abstract: At the core of its nature, security is a highly contextual and dynamic challenge. However, current security policy approaches are usually static, and slow to adapt to ever-changing requirements, let alone catching up with reality. In a 2012 Sophos survey, it was stated that a unique malware is created every half a second. This gives a glimpse of the unsustainable nature of a global problem, any improvement in terms of closing the 'time window to adapt' would be a significant step forward. To exacerbate the situation, a simple change in threat and attack vector or even an implementation of the so-called 'bring-your-own-device' paradigm will greatly change the frequency of changed security requirements and necessary solutions required for each new context. Current security policies also typically overlook the direct and indirect costs of implementation of policies. As a result, technical teams often fail to have the ability to justify the budget to the management, from a business risk viewpoint. This paper considers both the adaptive and cost-benefit aspects of security, and introduces a novel context-aware technique for designing and implementing adaptive, optimized security policies. Our approach leverages the capabilities of stochastic programming models to optimize security policy planning, and our preliminary results demonstrate a promising step towards proactive, context-aware security policies.

title: A real estate agent's view

authors: Umbers, Dave

abstract: Dave comes from a background of a career in farming where he progressed from being a shepherd to a manager of a large scale drystock farm. He then changed careers to Real Estate in 1996.
During the last 17 years Dave has worked in a variety of roles from a sales person to manager to principal and now business owner at VIPREALTY. During this time he has been involved in many millions of dollars’ worth of rural transactions. As a business owner and real estate professional he is very interested in the future direction farming will take to ensure our grandchildren will inherit a place to live that is at least as good, if not better than what we have today.
