ABSTRACT : Human beings are known to have heightened alertness when there is an impending security risk, during an attack or shortly after an attack. It is a confounding phenomenon since it seems to be the norm and also it has not received much investigative scholarly attention. Unfortunately, this kind of behaviour further reverses security mitigation measures that have been instituted and facilitates in further creating insecure environments. The study found that complacency leads to a high likelihood of security lapses/ breaches as confirmed by 45% of the respondents. The also study established that among possible measures to reduce instances of complacency in security management, administrative discipline, reduced working hours in a shift, transfers, prosecution of security managers for negligence and training ranked higher with 78%, 72%, 68%, 64% and 54% respectively. The study recommends empirical research to be done to gain understanding of complacency in security management practices.
