Virtual Private Network (VPN)

Key notes

  • A VPN creates an encrypted connection between a device and a remote server.

  • It can help:

    • Protect data on insecure networks.
    • Mask the user’s apparent IP address.
    • Secure remote access to organisational networks.

  • VPNs are widely used for:

    • Remote work.
    • Secure communication.
    • Accessing internal office resources.
  • A VPN does not guarantee complete anonymity.
  • The VPN provider may still be able to observe certain traffic metadata.

  • VPN security depends on:

    • Encryption.
    • Authentication.
    • Protocols.
    • Provider policies.
  • Common VPN protocols include WireGuard, OpenVPN and IPsec.
  • A VPN is different from antivirus software and does not itself remove malware.
