Aim and tasks of the work are to create principles of the incident tolerant computer system security evaluation, to examine the survivability of the modelled computer system examining its dependence on the security mechanism strength using the composed model. The tasks for achieving this aim are: to analyse the computer system security standards and security models; to compose the computer system attack classification which incorporates all the main features of the attack; to model typical threats to the computer system using graph theory; to perform the experimental study on the computer system security incidents; to analyse security mechanisms evaluating the modelling abilities; to compose a model of the computer system survivability; to examine the modelled computer system survivability dependence on the security mechanism strength.
