3. What is VPN ?
• A Virtual Private Network (VPN) is a network
technology that creates a secure network
connection over a public network such as the
Internet or a private network owned by a service
provider. Large corporations, educational
institutions, and government agencies use VPN
technology to enable remote users to securely
connect to a private network.

4. Common VPN
Protocols
• Point-to-Point Tunneling Protocol (PPTP)
• Layer 2 Tunneling Protocol (L2TP)
• Internet Protocol Security (IPSec)
• Secure Sockets Layer (SSL)

5. Why you want a
VPN ?
• You can use it to connect securely to a remote
network via the Internet. Most companies
maintain VPNs so that employees can access
files, applications, printers, and other resources
on the office network without compromising
security.

6. • If you're concerned about your online privacy,
connecting to an encrypted VPN while you're on a
public or untrusted network—such as a Wi-Fi
hotspot in a hotel or coffee shop—is a smart, simple
security practice. Because the VPN encrypts your
Internet traffic, it helps to stop other people who
may be trying to snoop on your browsing via Wifi to
capture your passwords.

7. • one of the best reasons to use a VPN is to regional
restrictions, known as geo-blocking on certain websites.
Journalists and political dissidents use VPNs to get
around state-sponsored censorship all the time, but you
can also use a VPN for recreational purposes, such as
connecting to a British VPN to watch the YouTube
videos in Pakistan. Because your Internet traffic routes
through the VPN, it looks as if you're just British visitor.
