Abstract:
This study considers the protection of information transmitted over computer networks that can be intercepted and decoded, or modified. It is shown that existing data protection methods use cryptography (traffic encryption). Just a few methods analyze the TTL field. We studied the TCP/IP protocol stack, the OSI network model, and the frame fields, and identified the header fields to be used. We presented the research tools and their configuration. We proposed a comprehensive reliability coefficient to assess the reliability of data transmission in corporate network through the use of verification packets. The composite coefficient includes various flags and fields from the TCP/IP network protocols, which are analyzed after reception. A hypothesis for building the reliability coefficient, and an approximate measurement scale are proposed. The analysis shows that the hypothesis and scale are correct.
