Encryption uses strong security methods like VPN, routers, WAN, TCP/IP, and firewalls to protect data. VPN acts as a dedicated private line over public networks. Routers connect multiple networks. WAN stands for Wide Area Network and connects distant computers. TCP/IP is the standard Internet protocol. Firewalls prevent outside access to organizational computer networks.
