%X Much is said about the importance of investing in information security [5, 10], but little is known on the extent and effectiveness of such security programmes [4]. A model that analyses the mechanics of an information security programme is presented. The model attempts to put an upper-bound on the information security expenditure. The concepts of ``viability of security expenditure,'' ``successfulness of attack'' and ``motivation to attack'' are introduced. The Return on Information Security Investment (ROISI) model is tested in a real life organization to determine the viability of an anti-spam solution in a conventional setting and later adapted to a wireless environment.
