Virtual Private Networks (VPN)
VPN, also known as Virtual Private Network, is a smart and the latest network technology. This technology is developed to help users create a highly-secure network connection over the web. With this technology integrated in your business architecture, you can rest assured that users located remotely are securely connected with your network.
To ensure maximum network security, the user needs to be authenticated so that they can easily access and use a private network when and as needed. An authenticated user generally has a unique ID and password. Also a token for authentication is provided to the user to gain network access in the form of a PIN. The PIN basically functions as the authentication code that is unique to every user.
Security Protocols
A wide array of Virtual Private Network Protocols are used to ensure data traffic security over the internet. Each protocol used varies in terms of the way they work to keep data secure.
The Virtual Private Network enables you to establish a strong and secure network connection, allowing your team to stay well-connected. To ensure data traffic security, several types of VPN protocols are used such as IP Security, SSL and PPTP.
L2TP/IPSec
Layer 2 Tunnel Protocol is a replacement of the PPTP VPN protocol. This protocol does not provide any encryption or privacy out-of-the-box and is frequently paired with security protocol IPsec. Once implemented, L2TP/IPsec is extremely secure and has no known vulnerabilities.
SSL
SSL (Secured Sockets Layer) uses the cryptography method to secure web based communications. It offers bank level security. To develop a connection, the user must successfully complete the authentication process that involves certificates or cryptographic keys. These are saved on the server.
PPTP
Point-to-Point Tunneling Protocol is one of the oldest VPN protocols in existence. Developed in the mid-90s by Microsoft, PPTP was integrated into Windows 95 and specifically designed for dial-up connections. But as technology advanced, PPTP’s basic encryption was quickly cracked, compromising its underlying security. However, because it lacks many of the security features found in other modern protocols it can deliver the best connection speeds for users who may not need heavy encryption. But while PPTP is still used in certain applications, most providers have since upgraded to faster more reliable protocols.
IKEv2
Internet Key Exchange version 2 is a common VPN tunneling protocol that provides a secure key exchange session. Similar to L2TP (and IKEv1), IKEv2 is normally paired with IPsec for encryption and authentication. This protocol is very good at re-establishing the link after temporary connection loss and excels at switching connections across network types (from WiFi to cellular, for example).
If you are looking to build a secure web based private network cost-effectively, the a VPN may be your best choice. It is an effective and inexpensive way to create a powerful and secure private network. It is a great alternative to leased and expensive private lines.
