MODELING THE PROCESS OF TWO-FACTOR AUTHENTICATION

The relevance of research. Authentication is the process confirming authenticity an object or subject interaction in information network by a presented identifier. Usually only one factor used. However, most security incidents occur due to use factor. easiest way create extra layer for accounts two-factor authentication using 2FA programs. In this case, additional step occurs, which increases user time and creates load on network. Thus, there need “Active Directory” directory service without component target system process, thereby making itself simpler more responsive user. purpose article develop model will allow comparison different approaches its implementation. Research progress. proposed consists three components: submodel, threat properties submodel. analysis performed showed advantages PERT method problem. simulation was carried out third-party checking second (DUO) method. final PERT-diagrams are formed. A comparative these methods terms speed out. Conclusion. developed makes it possible assess quality selected parameter with sufficient degree accuracy. particular, preferable results compared conventional methods.
