A methodology for cost-benefit analysis of information security technologies

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Although information security technologies (such as digital rights management products) has been proven effective and successful in protecting the confidentiality of sensitive information by providing access control, these technologies have not been widely adopted and used to their potential. One reason for this could be that cost and benefit of these products have not been analysed in a systematic and quantitative manner to date. As a result, companies do not have an established procedure to evaluate the cost and benefit of implementing these products. In this document, the benefits of implementing a digital rights management product in enterprises are quantified using stochastic Petri nets models and are compared with the security needs of a corporation and potential costs incurred by the implementation process. An evaluating procedure for implementing these products is established. This procedure has the potential to be used to improve the ability of a corporation to make sensible security investment decisions
