HTML5 Security Issues

Importance of this work comes from the fact that more and more attacks on information resources are made using HTML5 vulnerabilities every year. This work contains a theoretical study on the methods and possibilities of attacks using HTML5. Basic schemes of XSS and CSRF attacks, attacks on CORS, and intelligence-gathering activities in isolated network segments have been developed. As a practical example, an algorithm for implementing a CSRF attack has been considered and scenarios for preventing this attack have been developed. The outcome of research in this domain is a number of protective methods which have been developed against the basic types of attacks.
