Join Mike Chapple for an in-depth discussion in this video VPNs and VPN concentrators, part of CompTIA Security+ (SY0-501) Cert Prep: 2 Technologies and Tools.
- [Instructor] Virtual Private Networks, or VPNs,…provide two important network security functions…to IT administrators.…First, they allow the secure interconnection…of remote networks, such as connecting branch offices…to a corporate headquarters, or to each other.…Second, they provide mobile workers…with a mechanism to securely connect…from remote locations, back to the organization's network.…VPNs work by using encryption to create a virtual tunnel…between two systems over the internet.…
Everything that enters one end of the tunnel is encrypted…and then it is decrypted when it exits…the other end of the tunnel.…From the user's perspective,…the network appears to function normally.…But if an attacker gains access to traffic between…the two secure end points,…all they see is encrypted information…that they can't read.…VPNs require an endpoint on the remote network…that accepts VPN connections.…Many different devices may serve as VPN endpoints.…Such as a firewall, router, server,…or a dedicated VPN concentrator.…
