7th Australian Information Warfare and Security Conference, Edith Cowan University, Perth Western Australia, 4th - 5th December, 2006.


Information systems are used in overt and covert conflict and information operations target an opponent’s ability to manage information in support of operations for political, commercial and military advantage. System level attacks are complicated by logistic problems that require resources, command and control. Node level attacks are practical but of limited value. Collocated equipment comprises a temporary node that may be feasibly attacked. Estimation of IW operation merits may founder on the difficulty of predicting the net benefit for the costs. Starting from with Shannon’s model, a simple costbenefit model is discussed. Existing models are extended by an IW attack classification. A notional attack on system hardware is discussed with some defensive measures.
