Question

What are the main reasons why a VPN is the right solution for protecting the network perimeter? Do they also provide protection for mobile devices?
Explain the difference between an access control list (ACL) that is used in routers to block traffic and firewalls. What similarities do they share?

Answer 1

Explanation:

A VPN reduces security risk by allowing access to specific network resources to only users who are authorized, encrypting data and thereby protecting against insecure Wi-Fi access, and providing continuity of centralized unified magement

Answer 2

Answer:

This white paper examines the reasons as to why a VPN is the right solution for protecting the network perimeter while providing secure access to a variety of devices ranging from office computing devices to cellular smartphones and IoT. The main benefits of a VPN are:

1. A VPN is the easiest solution in all cases wherein an economical, isolated, secure, private network needs to be created or accessed over the Internet
2. A VPN allows you to leverage existing centralized network security infrastructure to provide a unified defense against cyber threats throughout the company’s networked devices regardless of location
3. A VPN provides secure access to needed internal services for a mobile workforce increasing their productivity
4. A VPN reduces security risk by allowing access to specific network resources to only users who are authorized, encrypting data and thereby protecting against insecure Wi-Fi access, and providing continuity of centralized unified threat management.

Introduction:

About 40% of United States organizations surveyed in 2016 by PwC admitted to being affected by cybercrime. We believe that while defense against cybercrime needs to be multipronged, network security is the foundation on which all the other safeguards rely.

As the variety and intensity of cyber threats increase, network administrators need to balance the desire of completely locking down their organization’s internal networks to the Internet, with the need to provide ubiquitous access to the internal network from a plethora of remote devices introduced by employees, contractors, and IoT. This balance can be achieved by making use of a Virtual Private Network (VPN) that leverages the Internet to provide secure virtual network access. This paper makes the case for use of VPN as a means to securely extend internal network services to a variety of authorized devices and users.

We start with the basics by introducing the concepts of a private network and a virtual private network. We then examine the need for a VPN and the key features that a good VPN solution should possess. We review OpenVPN Access Server solution features and show why it’s the best fit for VPN needs. Lastly, the paper concludes by illustrating how two OpenVPN deployments successfully satisfied the needs of diverse verticals and a use case for VPN remote
