Despite the consensus that information security should become an important consideration in IT governance rather than the sole responsibility of the IT department, important IT governance decisions are often made on the basis of fulfilling business needs alone while ignoring their implications for information security. We study how an important IT governance mechanism – the degree of centralized decision making – affects the likelihood of cybersecurity breaches. Examining a sample of 504 U.S. higher-education institutions over a four-year period, we find that a university with centralized IT governance is associated with fewer breaches. Interestingly, the effect of centralized IT governance is contingent on the heterogeneity of a university’s computing environment: Schools with more heterogeneous IT infrastructure benefit more from centralized governance. In addition, we find the relationship between centralized governance and cybersecurity breaches is most pronounced in public universities and those with more intensive research activities. We discuss the implications for research and practice.
