Is Emergency Management Considered A Component Of Business Continuity Management?, Kenny Frohde, David J. Brooks Dec 2013

Is Emergency Management Considered A Component Of Business Continuity Management?, Kenny Frohde, David J. Brooks

Australian Security and Intelligence Conference

Emergency Management (EM) and Business Continuity Management (BCM) frameworks incorporate measures of strategic and operational aspects. Defined within a number of Australian and international standards as well as guidelines, such concepts may be integrated to provide increased resilience for disruptive events. However, it has been found that there is some degree of misalignment of concept integration amongst security and EM bodies of knowledge. In line with cognitive psychology exemplar‐based concepts, such misalignments may be associated with a lack of precision in communality in the approach to EM and BCM. This article presents stage 1 of a two‐stage study. Stage 1 …

A Conceptual Model For Federated Authentication In The Cloud, Abdulwahid Al Abdulwahid, Nathan Clarke, Steven Furnell, Ingo Stengel

Australian Information Security Management Conference

Authentication is a key security control for any computing system, whether that is a PC, server, laptop, tablet or mobile phone. However, authentication is traditionally poorly served, with existing implementations falling foul of a variety of weaknesses. Passwords are poorly selected, reused and shared (to name but a few). Research has suggested novel approaches to authentication such as transparent authentication and cooperative and distributed authentication. However, these technologies merely focus upon individual platforms rather than providing a universal and federated authentication approach that can be used across technologies and services. The advent of cloud computing, its universal connectivity, scalability and …

Determining What Characteristics Constitute A Darknet, Symon Aked, Christopher Bolan, Murray Brand

Australian Information Security Management Conference

Privacy on the Internet has always been a concern, but monitoring of content by both private corporations and Government departments has pushed people to search for ways to communicate over the Internet in a more secure manner. This has given rise to the creations of Darknets, which are networks that operate “inside” the Internet, and allow anonymous participation via a de‐centralised, encrypted, peer‐to‐peer network topology. This research investigates some sources of known Internet content monitoring, and how they provided the template for the creation of a system to avoid such surveillance. It then highlights how communications on the Clearnet is …
