Tunneling in Cisco refers to the process of encapsulating one type of network protocol within another protocol to facilitate secure communication over a public or untrusted network. This technique is commonly used in Virtual Private Networks (VPNs) to create a secure "tunnel" for data packets, ensuring confidentiality and integrity. Cisco devices support various tunneling protocols, such as GRE (Generic Routing Encapsulation) and IPsec, which allow for the transport of data between remote sites or users and the corporate network. Tunneling enhances security by encrypting data and masking the original source and destination addresses.
PPTP tunneling was developed by Microsoft.
The Cisco 5510 offers an adaptive security program that comes with the router. The device also comes with VPN, split tunneling and firewall capabilities.

LEAP Lightweight Extensible Authentication Protocol, developed by Cisco, it allows for rotating WEP keys for wireless encryption, it's based on MS-CHAP authentication by Microsoft. This is outdated and should not be used unless necessary. PEAP is a joint venture between Microsoft, Cisco, and RSA for secure TLS tunneling with PKI certificates as authentication. EAP FAST is the new version of LEAP

Norwegian Tunneling Society was created in 1963.
