Which of the following is NOT a component of a hybrid VPN?

A hybrid VPN typically combines various types of virtual private networks (VPNs) to enhance security and flexibility. Among its key components, public network components are essential as they facilitate the connectivity between the different networks involved. Trusted VPNs are also crucial since they establish a level of trust between organizations or users to ensure secure communication. Dedicated security protocols further secure the data being transmitted, providing the necessary encryption and authentication processes.

Open access systems, however, are not a fundamental component of a hybrid VPN. This term generally refers to systems that allow unrestricted access to resources and information, often undermining the privacy and security that VPNs are designed to provide. Such systems do not specifically contribute to the structural or operational integrity of a hybrid VPN model, which is built around controlled and secure access to networks. Therefore, identifying open access systems as outside the scope of hybrid VPN components underscores their contrasting objectives in network security and management.
