One of the problems of organizing an information security system is to evaluate the functionality of the system as a whole. Approaches based on aggregated estimation can be used to solve such problems. Currently, such estimates are usually based on weighted averages, which does not allow modeling the concept of a key component of the system, that is, one whose loss leads to the non-functionality of the system as a whole or its individual subsystems. The paper shows an approach to the aggregated evaluation of the subsystem of software and technical solutions of the enterprise's integrated information security system based on the method of logical-axiological evaluation. A necessary part of such an assessment is the ontological modeling of the system by means of light ontologies reflecting the relationships between the components. Ontologies are constructed and an example of calculation for one of the subsystems is given.
