What is the most suitable solution for securing IP cameras when the vendor cannot authenticate at the camera level?

1. Deploy a VPN for cameras

2. Create a dedicated IP camera network with proxy authentication

3. Implement firewalls around the camera network

4. Use public network access

The correct answer is: Create a dedicated IP camera network with proxy authentication

Creating a dedicated IP camera network with proxy authentication is the most suitable solution for securing IP cameras when vendor authentication cannot be performed at the camera level. This method involves isolating the cameras on a separate network, which serves to contain and minimize potential risks from unauthorized access. By using proxy authentication, even if the cameras themselves cannot authenticate users or devices, the proxy acts as an intermediary that moderates access to the cameras based on predetermined security measures. This effectively protects the IP cameras from external threats and unauthorized connections. In contrast, deploying a VPN for cameras, while beneficial for secure data transmission, might not adequately address the fundamental issue of the cameras' lack of individual authentication. Similarly, implementing firewalls around the camera network can help control traffic in and out but does not provide a layer of user authentication for the cameras themselves. Finally, using public network access would significantly increase the risk of exposure to unauthorized access and cyber threats, as it does not provide any protection or isolation for the cameras. Thus, creating a dedicated IP camera network with proxy authentication presents a pragmatic and effective security approach.
