Abstract

As organizations become increasingly dependent on information systems (IS) for strategic advantage and operations, the issue of IS security also becomes increasingly important. In the interconnected electronic business environment of today, security concerns are paramount. Management must invest in IS security to prevent abuses that can lead to competitive disadvantage. Using the literature on security practices and organizational factors, this study develops an integrative model of IS security effectiveness and empirically tests the model. The data were collected through a survey of IS managers from various sectors of the economy. Small and medium-sized enterprises were found to engage in fewer deterrent efforts compared to larger organizations. Organizations with stronger top management support were found to engage in more preventive efforts than organizations with weaker support from higher management. Financial organizations were found to undertake more deterrent efforts and have stiffer deterrent severity than organizations in other sectors. Moreover, greater deterrent efforts and preventive measures were found to lead to enhanced IS security effectiveness. Implications of these findings for further research and practice are discussed.
