Excuse me, could you please clarify something for me? I came across a statement that suggested VPNs might be considered as a layer 5 technology, but I'm a bit confused. As I understand, the OSI model comprises seven layers, and VPNs are typically associated with providing secure connections at the network layer, which is layer 3. Is there a particular context or interpretation in which VPNs could be seen as operating at layer 5, or is this simply a misconception? I'd appreciate your insight on this matter.

Another option is to design VPNs on Layer 4, the transport layer. This approach focuses on providing secure communication channels between endpoints, ensuring data integrity and confidentiality.

In the context of network architecture, VPNs can be structured to operate at different layers of the Open Systems Interconnection model (OSI model).

One common approach is to design VPNs based on Layer 3, the network layer. This allows for the creation of secure, private networks over a shared or public infrastructure.

The choice between Layer 3 and Layer 4 VPNs depends on the specific needs and requirements of the organization deploying the VPN.
