Software-based methods of information resources accessibility assessment are applied taking into consideration preventive measures of security audits. The elements of the instrumental-oriented technique for rational functioning of the system in conditions of successive attacks on the service configuration DNS vulnerabilities and periodic preventive measures (particular, auditing of software security) to detect and correct vulnerabilities with their subsequent elimination without changing the code or using patches are suggested. The MATLAB is used to simulate behavior of the systems.
