Virtual Private Network (VPN) connections provide a secure way to access the FortiGate CLI remotely by encrypting data in transit and hiding IP addresses. To enable VPN on a FortiGate device, administrators must configure VPN client access and set up a VPN server instance.

1. Navigate to `VPN -> IPsec Wizard -> Site-to-Site` and select `Site-to-Site VPN`.
2. Configure the `Local’ and `Remote’ tunnel interfaces and select the security protocol (e.g., AES-256).
3. Set up the `Remote’ VPN gateway and configure the `Local’ subnet.

Certificate-Based Authentication

Certificate-based authentication provides an additional layer of security for remote CLI access by verifying the user’s certificate against a trusted Certificate Authority (CA). To enable certificate-based authentication, administrators must create a Certificate Authority (CA) and import the user’s certificate.

1. Navigate to `System Setting -> Administration -> Certificates` and select `CA’.
2. Create a new `Certificate Authority’ and import the user’s certificate.
3. Navigate to `System Setting -> Administration -> Authentication` and select `Certificate’.
4. Set `Certificate Authentication’ to `Enable’ and select the CA and user certificate.

Certificate-based authentication provides an additional layer of security as it prevents attackers from using forged certificates to authenticate. This method also provides an audit trail of authentication attempts, allowing administrators to track user activity and detect potential security breaches.
