Virtual Private Networks (VPN)
This document provides a comprehensive overview of Virtual Private Networks (VPNs) as implemented within the MS Network Services infrastructure. It covers the fundamental concepts, supported protocols, configuration guidelines, and best practices for secure and efficient VPN usage.
What is a VPN?
A Virtual Private Network (VPN) extends a private network across a public network, such as the Internet. It allows users to send and receive data as if their computing devices were directly connected to the private network. This is achieved by creating an encrypted tunnel between the user's device and the network gateway.
Key Benefits of Using VPNs:
- Security: Encrypts data traffic, protecting sensitive information from interception, especially on public Wi-Fi networks.
- Privacy: Masks the user's IP address, enhancing anonymity and preventing tracking.
- Remote Access: Enables secure access to internal company resources from remote locations.
- Geo-unblocking: Allows access to content or services that might be restricted in a user's geographical location.
Supported VPN Protocols at MS Network Services:
We currently support the following VPN protocols:
-
OpenVPN: A highly configurable and widely adopted open-source VPN solution known for its security and flexibility.
- Use Case: Recommended for most user-to-network connections and site-to-site VPNs.
- Features: Robust encryption (AES-256), TLS authentication, supports various transport protocols (TCP/UDP).
-
IPsec (with IKEv2): A suite of protocols used to secure IP communications by authenticating and encrypting each IP packet. IKEv2 provides efficient and reliable key exchange.
- Use Case: Often used for site-to-site connections and mobile devices due to its native support and stability.
- Features: Strong encryption, authentication, integrity, NAT traversal.
Important Note:
We are phasing out support for older protocols like PPTP and L2TP/IPsec (pre-shared key) due to security vulnerabilities. Please migrate to OpenVPN or IPsec/IKEv2 for all new deployments.
Client Configuration Guides:
Detailed guides for setting up VPN clients on various operating systems and devices are available:

Server Configuration and Management:
Information regarding VPN server deployment, management, and monitoring is intended for network administrators.
Security Best Practices:
- Always use strong, unique passwords for VPN access.
- Keep your VPN client software updated to the latest version.
- Be cautious when connecting to unfamiliar public Wi-Fi networks; ensure your VPN is active.
- If you suspect any security breach or unauthorized access, please contact the IT Security team immediately.
Tip:
For enhanced security, consider enabling multi-factor authentication (MFA) for your VPN connections if available.
