A Survey on the Implementation and Management of Secure Virtual Private Networks (VPNs) and Virtual LANs (VLANs) in Static and Mobile Scenarios

Nowadays, the demand for connection between remote offices of a company, or research locations, and constantly increasing work mobility (partly due to current pandemic emergency) have grown hand in with quality speed broadband connections. The logical consequence this scenario is increasingly widespread use Virtual Private Network (VPN) They allow one securely connect two ends via dedicated network, typically using Internet reducing costs Content Delivery (CDN) lines (dedicated connections). At same time, Local Area Networks (VLANs) are able decrease impact some scalability issues large networks. Given background above, paper focused on overviewing surveying main progresses related VPNs VLANs wireless networks, by collecting most important contributions area describing how they can be implemented. We state that security effectively mitigated through combination good network-management practices, effective network design application advanced products. However, obviously, implementation poses specific regarding information security; thus solutions also surveyed.
