Virtual private networks VPNs have long been a trusted tool in securing network communication transmitted across the dark void that is the public internet. Whether this network communication is point-to-point, establishing a secured connection between two corporate offices, or simply client computers remotely connecting to the corporate network, VPNs can help secure this communication through both strong authentication and encryption. While VPNs have been around for decades, the world of infosec has evolved over that time, bringing about a world of mobile devices, public wi-fi, and a host of new attack vectors for malicious users. VPNs continue to have a place in infosec, but the waters have muddied somewhat over the years. This secure connection involves authentication, where the end user or device confirms with the VPN server that they are who they claim to be.

What is Enterprise Private Network? - Definition from Techopedia
A virtual private network VPN extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
Applications running on a computing device, e. Encryption is a common, though not an inherent, part of a VPN connection. VPN technology was developed to allow remote users and branch offices to access corporate applications and resources. To ensure security, the private network connection is established using an encrypted layered tunneling protocol and VPN users use authentication methods, including passwords or certificates, to gain access to the VPN.
In other applications, Internet users may secure their connections with a VPN, to circumvent geo-restrictions and censorship , or to connect to proxy servers to protect personal identity and location to stay anonymous on the Internet. However, some websites block access to known VPN technology to prevent the circumvention of their geo-restrictions, and many VPN providers have been developing strategies to get around these roadblocks. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated circuits or with tunneling protocols over existing networks.
From a user perspective, the resources available within the private network can be accessed remotely. Early data networks allowed VPN-style connections to remote sites through dial-up modem or through leased line connections utilizing X. These networks are not considered true VPNs because they passively secure the data being transmitted by the creation of logical data streams. VPNs can be characterized as host-to-network or remote access by connecting a single computer to a network, or as site-to-site for connecting two networks.
In a corporate setting, remote-access VPNs allow employees to access the company's intranet from outside the office. Site-to-site VPNs allow collaborators in geographically disparate offices to share the same virtual network. A VPN can also be used to interconnect two similar networks over a dissimilar intermediate network; for example, two IPv6 networks over an IPv4 network. VPNs cannot make online connections completely anonymous, but they can usually increase privacy and security.
To prevent disclosure of private information, VPNs typically allow only authenticated remote access using tunneling protocols and encryption techniques. Tunnel endpoints must be authenticated before secure VPN tunnels can be established. User-created remote-access VPNs may use passwords , biometrics , two-factor authentication or other cryptographic methods. Network-to-network tunnels often use passwords or digital certificates. They permanently store the key to allow the tunnel to establish automatically, without intervention from the administrator.
A device that is within a customer's network and not directly connected to the service provider's network. C devices are not aware of the VPN. Sometimes it is just a demarcation point between provider and customer responsibility.
Other providers allow customers to configure it. A PE is a device, or set of devices, at the edge of the provider network which connects to customer networks through CE devices and presents the provider's view of the customer site.
A P device operates inside the provider's core network and does not directly interface to any customer endpoint. It might, for example, provide routing for many provider-operated tunnels that belong to different customers' PPVPNs. Its principal role is allowing the service provider to scale its PPVPN offerings, for example, by acting as an aggregation point for multiple PEs.
P-to-P connections, in such a role, often are high-capacity optical links between major locations of providers. VLANs frequently comprise only customer-owned facilities. Whereas VPLS as described in the above section OSI Layer 1 services supports emulation of both point-to-point and point-to-multipoint topologies, the method discussed here extends Layer 2 technologies such as EtherIP has only packet encapsulation mechanism.
It has no confidentiality nor message integrity protection. It may support IPv4 or IPv6. This section discusses the main architectures for PPVPNs, one where the PE disambiguates duplicate addresses in a single routing instance, and the other, virtual router, in which the PE contains a virtual router instance per VPN. RDs disambiguate otherwise duplicate addresses in the same PE. By the provisioning of logically independent routing domains, the customer operating a VPN is completely responsible for the address space.
Some virtual networks use tunneling protocols without encryption for protecting the privacy of data. While VPNs often do provide security, an unencrypted overlay network does not neatly fit within the secure or trusted categorization.
Trusted VPNs do not use cryptographic tunneling, and instead rely on the security of a single provider's network to protect the traffic. From the security standpoint, VPNs either trust the underlying delivery network, or must enforce security with mechanisms in the VPN itself.
Unless the trusted delivery network runs among physically secure sites only, both trusted and secure models need an authentication mechanism for users to gain access to the VPN. Users utilize mobile virtual private networks in settings where an endpoint of the VPN is not fixed to a single IP address , but instead roams across various networks such as data networks from cellular carriers or between multiple Wi-Fi access points without dropping the secure VPN session or losing application sessions.
With the increasing use of VPNs, many have started deploying VPN connectivity on routers for additional security and encryption of data transmission by using various cryptographic techniques. Supported devices are not restricted to those capable of running a VPN client.
Many router manufacturers supply routers with built-in VPN clients. Setting up VPN services on a router requires a deep knowledge of network security and careful installation.
Minor misconfiguration of VPN connections can leave the network vulnerable. Performance will vary depending on the Internet service provider ISP. A limitation of traditional VPNs is that they are point-to-point connections, and do not tend to support broadcast domains. Therefore, communication, software, and networking, which are based on layer 2 and broadcast packets , such as NetBIOS used in Windows networking , may not be fully supported as on a local area network.
Users must consider that when the transmitted content is not encrypted before entering a VPN, that data is visible at the receiving endpoint usually the public VPN provider's site , regardless of whether the VPN tunnel wrapper itself is encrypted for the inter-node transport. The only secure VPN is where the participants have oversight at both ends of the entire data path, or the content is encrypted before it enters the tunnel provider.
