Tunneling in VPNs refers to the process of encapsulating VPN data packets within regular IP packets for transmission through a public network like the Internet. This encapsulation creates a "tunnel" between the VPN endpoints that provides security and allows private network traffic to be carried across a shared infrastructure.
This ppt show the very fundamental aspects of VPN(Virtual Private Networks) and show why it is used and its associated benefits. Also show characteristics, Tunneling, Encapsulation, etc.

A virtual private network gives secure access to LAN resources over a shared network infrastructure such as the internet. It can be conceptualized as creating a tunnel from one location to another, with Encrypted data traveling through the tunnel before being decrypted at its destination.
Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.

3. What is VPN?
Virtual Private Network is a type of
private network that uses public
telecommunication, such as the Internet,
instead of leased lines to communicate.
Became popular as more employees worked
in remote locations.
Terminologies to understand how VPNs
work.
4. Private Networks
vs.
Virtual Private Networks
Employees can access the network (Intranet)
from remote locations.
Secured networks.
The Internet is used as the backbone for
VPNs
Saves cost tremendously from reduction of
equipment and maintenance costs.
Scalability
6. Brief Overview of How it
Works
Two connections – one is made to the
Internet and the second is made to the
VPN.
Datagrams – contains data, destination and
source information.
Firewalls – VPNs allow authorized users to
pass through the firewalls.
Protocols – protocols create the VPN
tunnels.
7. Four Critical Functions
Authentication – validates that the data
was sent from the sender.
Access control – limiting unauthorized
users from accessing the network.
Confidentiality – preventing the data to be
read or copied as the data is being
transported.
Data Integrity – ensuring that the data
has not been altered
8. Encryption
Encryption -- is a method of
“scrambling” data before
transmitting it onto the Internet.
Public Key Encryption Technique
Digital signature – for authentication
9. Virtual Private Network
• Operates at layer 2 or 3 of OSI model
– Layer 2 frame – Ethernet
– Layer 3 packet – IP
• Tunneling
– allows senders to encapsulate their data in IP
packets that hide the routing and switching
infrastructure of the Internet
– to ensure data security against unwanted
viewers, or hackers.
10. Tunneling
A virtual point-to-point connection
made through a public network. It
transports encapsulated datagrams.
Original Datagram
Encrypted Inner Datagram
Datagram Header Outer Datagram Data Area
Data Encapsulation [From Comer]
Two types of end points:
Remote Access
Site-to-Site
11. Four Protocols used in
VPN
PPTP -- Point-to-Point Tunneling
Protocol
L2TP -- Layer 2 Tunneling Protocol
IPsec -- Internet Protocol Security
Transport Mode

SOCKS – is not used as much as the
ones above
13. Types of
Implementations
What does “implementation” mean in
VPNs?
3 types
Intranet – Within an organization
Extranet – Outside an organization
Remote Access – Employee to Business
19. Advantages: Cost
Savings
• Eliminating the need for expensive long-
distance leased lines
• Reducing the long-distance telephone
charges for remote access.
• Transferring the support burden to the
service providers
• Operational costs
•
21. Disadvantages
VPNs require an in-depth understanding of
public network security issues and proper
deployment of precautions
Availability and performance depends on
factors largely outside of their control
Immature standards
VPNs need to accommodate protocols other
than IP and existing internal network
technology
22. Applications: Site-to-Site
VPNs
Large-scale encryption between
multiple fixed sites such as remote
offices and central offices
Network traffic is sent over the
branch office Internet connection
This saves the company hardware and
management expenses
24. Applications: Remote
Access
Encrypted connections between mobile or
remote users and their corporate networks
Remote user can make a local call to an ISP,
as opposed to a long distance call to the
corporate remote access server.
Ideal for a telecommuter or mobile sales
people.
VPN allows mobile workers & telecommuters
to take advantage of broadband connectivity.
i.e. DSL, Cable
25. Industries That May Use a
VPN
Healthcare: enables the transferring of confidential
patient information within the medical facilities & health
care provider
Manufacturing: allow suppliers to view inventory & allow
clients to purchase online safely
Retail: able to securely transfer sales data or customer
info between stores & the headquarters
Banking/Financial: enables account information to be
transferred safely within departments & branches
General Business: communication between remote
employees can be securely exchanged
26. Where Do We See VPNs
Going in the Future?
VPNs are continually being enhanced.
Example: Equant NV
As the VPN market becomes larger, more
applications will be created along with more
VPN providers and new VPN types.
Networks are expected to converge to
create an integrated VPN
Improved protocols are expected, which will also
improve VPNs.
