Vpn Labs
Virtual Private Network (VPN) Lab – SEED Labs
Overview
A Virtual Private Network (VPN) is used for creating a private scope
of computer communications or providing a secure extension of a private
network into an insecure network such as the Internet. VPN is a widely
used security technology. VPN can be built upon IPSec or
Transport Layer Security (TLS/SSL). These are two fundamentally different
approaches for building VPNs. In this lab, we focus
on the TLS/SSL-based VPNs. This type of VPNs is often referred to
as TLS/SSL VPNs.
The learning objective of this lab is for students to master the
network and security technologies underlying SSL VPNs.
The design and implementation of TLS/SSL VPNs exemplify
a number of security principles and technologies,
including crypto, integrity, authentication, key management, key exchange,
and Public-Key Infrastructure (PKI).
To achieve this goal, students will implement
miniVPN, a simple TLS/SSL VPN, in the Linux
operating system.

What Is a VPN? – Virtual Private Network – Cisco
How does a virtual private network (VPN) work?
A VPN extends a corporate network through encrypted connections made over the Internet. Because the traffic is encrypted between the device and the network, traffic remains private as it travels. An employee can work outside the office and still securely connect to the corporate network. Even smartphones and tablets can connect through a VPN.
What is secure remote access?
Secure remote access provides a safe, secure way to connect users and devices remotely to a corporate network. It includes VPN technology that uses strong ways to authenticate the user or device. VPN technology is available to check whether a device meets certain requirements, also called a device’s posture, before it is allowed to connect remotely.
Is VPN traffic encrypted?
Yes, traffic on the virtual network is sent securely by establishing an encrypted connection across the Internet known as a tunnel. VPN traffic from a device such as a computer, tablet, or smartphone is encrypted as it travels through this tunnel. Offsite employees can then use the virtual network to access the corporate network.
Frequently Asked Questions about vpn labs
What is VPN lab?
A Virtual Private Network (VPN) is used for creating a private scope of computer communications or providing a secure extension of a private network into an insecure network such as the Internet. … The learning objective of this lab is for students to master the network and security technologies underlying SSL VPNs.
What is a VPN used for?
A virtual private network, or VPN, is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely transmitted. It prevents unauthorized people from eavesdropping on the traffic and allows the user to conduct work remotely.
What is a virtual private network VPN PDF?
A virtual private network (VPN) can be defined as a way to provide secure communication between members of a group through use of public telecommunication infrastructure, maintaining privacy through the use of a tunneling protocol and security procedures.
