What Is a Virtual Private Network (VPN) in Cybersecurity?
A virtual private network, or VPN, owned by a VPN provider is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely transmitted.
VPN typically provides a secure, private connection between two points communicating over a public network. 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.
There are 3 types of VPNs for Cybersecurity, which are -
- Remote access VPN (or client-to-site VPN): Connect to a private network or third-party server via SSL/TSL.
- Site-to-site VPN: Network connects to another network via LAN, WAN.
- VPN applications: Connect to a private network via VPN app on mobile or smartphone device
A Robust Virtual Private Network (VPN) Must:
|
Encrypt IP Address Primary job of a VPN is to hide the IP address from an ISP and other third parties. Allows sending and receiving information online without the risk of anyone seeing it. |
Encrypt Protocols Prevents from leaving traces, for example, in the form of internet history, search history and cookies - preventing third parties from gaining access to confidential information |
Offer Two-factor Authentication Using a variety of authentication methods, a strong VPN authenticates everyone trying to log in – helps avoid uninvited third parties' access secure connections. |
Facilitate Kill Switch When a VPN connection is suddenly interrupted, so will the secure connection. A robust VPN detects sudden downtime and terminates preselected programs, reducing the likelihood of compromised |
