The field of information security routinely produces the need for a security information and event management system operator who would be capable of durable and extensive (e.g., workday-long) monitoring of the system in his control with well-timed decision making in emergencies. The obvious concern is that such continuous exertion is bound to lead to the operator's increased fatigue, reduced attention span, and flawed deci- sion making. This paper proposes methods of the visualization system’s adaptation to these changes for improving the operator's efficiency in terms of speed and accuracy.
