description: The topic of the graduate qualification work is Â«Searching for vulnerabilities in implementations of network protocols of the IPsec family using dynamic analysis toolsÂ».The purpose of the study is increase the code coverage during fuzzing testing of the IKE protocol by modifying the existing fuzzing testing system for this protocol. The subject of the work is the methods and algorithms of fuzzing testing. The object of the research is complete modern implementations of the IPsec protocol with support for extensions for Linux kernels. The research set the following goals:Study of the main existing approaches and tools for finding vulnerabilities in software.Analysis of the features of fuzzing testing of the IKE protocol and the formation of requirements for the analysis system.Development of a way to increase the coverage of the program code through the use of a generator.Building a fuzzing testing system for the IKE protocol using the proposed improvements.In the course of the work, a change was made to the existing system for fuzzing testing of the IKE protocol, and modern varieties of fuzzing testing were also analyzed.As a result of the work, a tool was developed for generating configuration files for the initiator of the IKE exchange interaction, which works in a certain fuzzing system, and a rationale for the effectiveness of the developed tool was also carried out.The results obtained can be used in further modifications and additions to fuzzing testing systems for both security protocols from the IPsec family and for implementations of other network protocols.
