VPNs and secure remote access
Protect remote connections with encryption.
📖 Key ideas
- A VPN creates an encrypted tunnel over the internet.
- Site-to-site VPNs connect offices; remote-access VPNs connect users.
- Protocols: IPsec, OpenVPN, WireGuard.
- Zero-trust network access (ZTNA) checks each request.
- Use MFA for remote access.
💡 Real-life example: A VPN is a covered tunnel through a crowded market: you pass through but nobody sees what you carry.
