Five years ago, cyber-security wasn't something you'd necessarily associate with daily business practice. Lines of code felt meaningless and the concept itself still seemed futuristic. Most companies were unwilling to overhaul their entire strategies to combat this potential threat, and an ‘it won't happen to me’ attitude was commonplace. No longer can security be viewed as a prohibited silo residing outside of key boardroom discussions. An organisation's security strategy must be aligned with business strategy and integral to the senior leadership's decision-making process. For organisations to operate safely in the contemporary threat landscape, they need to make sure they are consistently evaluating the effectiveness of their defences to be as secure as possible. At the same time they must ensure that they are utilising the most modern solutions and have the right expertise at hand, explains Lee James of Rackspace.

This paper presents the results of an effort to create a comprehensive and systematic procedure for developing warning message prioritization rules in integrated Collision Warning Systems (CWS) for heavy trucks. Although there are existing guidelines and even ISO standards for accomplishing this, in practice these sources are inadequate because they are not designed to handle the high degree of complexity and large number of warning conflict permutations that occur in integrated systems that have multiple subsystems, each with multiple warning levels. This paper presents a procedure that expands on existing sources, but has the level of detail and structured tools necessary to represent the variety of information that requires consideration when making decisions about the prioritization of warning messages.
