Wide Area Network (WAN)

Wide Area Network (WAN) 

WAN, a computer network that spans a large geographical area. Typically, a 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 Internet. They also connect through leased lines or satellites.  

WAN Security  

WAN Security encompasses your corporate offices but also your employee’s homes. WAN security is best kept by requiring all users 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 were 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. Total Computer Solutions (TCS) recommends that all devices become part of your network and join via a VPN. The devices should be managed and secure. Up to date security patches should be mandatory, having corporate anti-malware software installed and full domain security should be implemented. It might be an employee’s home computer and not company property, but if a VPN connection is set up with that device, then that home computer just became a node on your corporate network. As a node, it can spread viruses, ransomware, and malware on the LAN
