Methods of Vulnerability Analysis and Cybersecurity when Choosing VPN Products

This paper investigates possible threats and risks to information security arising from the use of VPN products. A combined methodology for assessing the security of VPN products is pro-posed, which includes the IMECA (Intrusion Modes and Effects Criticality Analysis) method, as well as some so-called static and dynamic methods. This allows you to make an informed choice of a VPN product for secure Internet use, taking into account your personal prefer-ences. The combined vulnerability analysis methodology involves determining the criticality of threats, taking into account the likelihood of their occurrence and implementation, as well as the severity of the consequences. Based on the results of the analysis, the choice of appropri-ate countermeasures in the form of VPN product features to minimize risks and increase the security of their users is substantiated. The practical significance of the results for improving cybersecurity is determined. The article is based on a study of the features of VPN products and proposes a new approach that includes IMEСA and experimental methods.
