Wide Area Network (WAN)

WAN, a computer network that spans a relatively large geographical area. Typically, a Wide Area Network (WAN) consists of two or more local-area networks (LANs). Computers connected to a wide area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The most massive WAN in existence is the Internet.

Wide Area Network Security

Wide Area Network (WAN) Security encompasses your corporate offices but also your employee’s homes. Wide area network security is best maintained by requiring all users who are connecting to your WAN to connect via Virtual Private Network (VPN). A VPN creates a secure tunnel that protects your data and allows all traffic, voice or data to pass through a public WAN as if it was on a private circuit or LAN.

A hacker successfully breached Microsoft security by gaining access to a Microsoft employee’s home computer. The employee connected to the corporate office through the VPN, the hacker could merely follow that same connection and gain access to Microsoft. Typically, one of the weakest points of your network security is the computer that connects from home. TCS recommends that all devices that become part of your network either via a WAN or a VPN. The devices should be managed and secured. Up to date security patches should be required, having corporate anti-malware software installed and full domain security should be implemented. It might be a home computer and not company property, but if a VPN connection is established that home computer just became a node on your network. This can now spread viruses, Trojans, and malware on the LAN.
