57. The security team notices that the Always On VPN solution sometimes fails to connect. This leaves remote users unprotected because they cannot connect to the on-premises web proxy. Which of the following changes will best provide web protection in this scenario?
Answer: D
Installing a host-based content filtering solution best provides web protection in this scenario.
Implementing a host-based content filtering solution ensures that remote users have continued protection even when the Always On VPN fails to connect. This solution operates directly on the user's device, allowing for real-time content filtering regardless of the VPN status.
A) Implement network access control
While network access control can help manage which devices can access the network, it does not provide direct web protection for remote users when they are unable to connect through the VPN. Thus, it does not address the immediate need for security in situations where the VPN connection fails.
B) Configure the local gateway to point to the VPN
Configuring the local gateway to point to the VPN is more about establishing a proper connection rather than providing web protection. If the VPN fails, this option would not protect users from web threats, making it an inadequate solution for the scenario presented.
C) Create a public NAT to the on-premises proxy
Creating a public NAT to the on-premises proxy may allow remote users to access the proxy directly, but it does not ensure that the traffic is filtered for security purposes. This approach could expose users to potential threats when the VPN connection is not established.
D) Install a host-based content filtering solution
Installing a host-based content filtering solution effectively protects users by filtering web content directly on their devices. This approach remains effective even when the VPN connection is not available, thus providing a consistent layer of security against web-based threats.
Conclusion
The installation of a host-based content filtering solution is the most effective measure to ensure web protection for remote users, particularly in scenarios where the Always On VPN fails. Other options either do not address the core issue of web security or fail to provide adequate protection when the VPN is down, making them less suitable for this situation.
