37. 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 will best provide web protection in this scenario.
A host-based content filtering solution ensures that users remain protected by filtering web content directly on their devices, even when they are unable to connect to the Always On VPN solution.
A) Implement network access control.
Implementing network access control may enhance security by managing who can access the network, but it does not provide immediate web protection for remote users who cannot connect to the VPN. This option does not address the specific issue of unprotected users when the VPN fails.
B) Configure the local gateway to point to the VPN.
Configuring the local gateway to point to the VPN could potentially help with connectivity issues, but it does not directly provide web protection when the VPN connection is not established. Without a working VPN, users will still be unprotected.
C) Create a public NAT to the on-premises proxy.
Creating a public NAT to the on-premises proxy might allow users to access the proxy, but it exposes the proxy to the internet, which can introduce security vulnerabilities. This option does not ensure that users are protected from malicious content when the VPN is unavailable.
D) Install a host-based content filtering solution.
Installing a host-based content filtering solution directly addresses the issue of providing web protection for remote users. This solution ensures that even if the VPN fails, the devices can still block harmful content and protect users from security threats.
Conclusion
The host-based content filtering solution is the most effective option for ensuring web protection for remote users when the Always On VPN solution fails. It directly mitigates the risks associated with unprotected access to the internet, while the other options either do not provide adequate protection or introduce additional vulnerabilities.
