To ensure always-on VPN access is enabled and restricted to company assets, the network engineer needs to generate device certificates using the specific template settings required for the company's VPN solution. These certificates ensure that only authorized devices can establish a VPN connection.
Why Device Certificates are Necessary:
Authentication: Device certificates authenticate company assets, ensuring that only authorized devices can access the VPN.
Security: Certificates provide a higher level of security compared to username and password combinations, reducing the risk of unauthorized access.
Compliance: Certificates help in meeting security policies and compliance requirements by ensuring that only managed devices can connect to the corporate network.
Other options do not provide the same level of control and security for always-on VPN access:
B. Modify signing certificates for IKE version 2: While important for VPN protocols, it does not address device-specific authentication.
C. Create a wildcard certificate: This is not suitable for device-specific authentication and could introduce security risks.
D. Add the VPN hostname as a SAN entry: This is more related to certificate management and does not ensure device-specific authentication.
