აბსტრაქტი. In information networks, when detecting and recognizing cyber-attacks, they are usually interested not only in the fact of the appearance of a particular attack, but also in its informative parameters. The result of actions performed in solving the problem of the presence of a cyberattack depends on the degree of closeness of the estimate to the true value of the parameters. Therefore, losses in the process of recognizing (detecting) and evaluating a cyberattack depend both on errors in its detection and on the inaccuracy of assessment, which will not allow providing adequate countermeasures, and at the same time the task of joint development and evaluation arises. In practice, the moment of making a decision is very important, since with an increase in the observation time, the costs increase and, therefore, the fastest decision-making is desirable. At the same time, sequential detection-estimation procedures are more effective than inconsistent ones. Therefore, finding the optimal, consistent or close to them procedures will increase the cybersecurity of information.
Some results related to joint sequential detection and estimation, obtained in the works of other authors, show that in the general case it is not possible to find a constructive solution even in a two-alternative problem. Therefore, the authors made an attempt to solve the problem of multi-alternative sequential detection and evaluation of a cyberattack with a random moment of its occurrence.
