This article details the importance of assessing the vulnerabilities of network protocols and systems and the steps required to implement them. The article emphasizes that the main goal of vulnerability research is the timely identification of information security problems and their elimination. At the same time, the dependence of the main indicators of network efficiency on the protocols used in it is also scientifically   substantiated.  Information security issues were  analyzed by integrating metrics obtained from assessing the impact of attacks in various areas of network packets into network monitoring systems. The article also provides an in-depth analysis of the advantages and disadvantages of network protocols, and also examines each of them from the point of view of information security.
