Functional model of firewall application layer protection for WEB-Based information systems

The purpose of this article is to develop a functional model of an effective application layer firewall to protect the Web-based information systems. For successful achievement of this goal, analysis of the vulnerability of the application layer protocols and the existing means of solving these problems is performed in the paper. The technology and methods of implementation of protection means of the Web-oriented information systems at the application level are examined. The functional model of the application layer firewall for the Web-based information systems protection is designed. In the process of the research, the methods for implementation of protective means of the Web-oriented information systems at the application level were used.
