description: The subject of the graduate qualification work is: âThe use of fuzzing and symbolic execution methods in the study of network protocol securityâ. This work is devoted to the study of security analysis methods in the implementation of network protocols and the development of a tool that is more efficient than existing solutions. The research set the following goals: 1. Analysis of the possibilities of using the methods of fuzzing and symbolic execution in the study of the security of network protocols. 2. Designing a method for the joint use of fuzzing and symbolic execution to study the security of network protocols. 3. Development of a prototype that performs the procedure for analyzing the security of network protocols. 4. Development of methods for the effective use of fuzzing and symbolic execution methods in the study of network protocol security. A significant part of the material was collected from open sources on the Internet: documentation of tools, description of methods. Comparative tests of tool effectiveness have been conducted. To test the effectiveness, we used open source SMTP protocol implementations, as well as the gcov utility. As a result, a study was conducted of the methods of security analysis in implementations of network protocols, the methods of fuzzing and symbolic execution were studied, as well as the principle of operation of tools that implement these methods. Based on the test results, the most effective ones were determined. To increase the effectiveness of security analysis, a method for the combined use of fuzzing and symbolic performance was proposed, and a prototype tool that combines these methods was implemented.
