8. 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 even if the Always On VPN fails to connect, remote users are still protected from accessing harmful content while using their devices.
A) Implement network access control.
Implementing network access control may help manage who can connect to the network but does not directly address the issue of remote users being unprotected when the VPN fails. This option does not provide a solution for filtering web traffic or securing users when they cannot connect to the on-premises proxy.
B) Configure the local gateway to point to the VPN.
While configuring the local gateway to point to the VPN could potentially improve connectivity, it does not address the protection of users when the VPN connection is unsuccessful. This option fails to ensure that users have web protection in scenarios where the VPN is not available.
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 directly, but it exposes the proxy to the internet, which can pose significant security risks. This option does not provide a protective measure for remote users, especially when they are unable to connect through the VPN.
D) Install a host-based content filtering solution.
Installing a host-based content filtering solution effectively protects remote users by filtering web traffic directly on their devices. This solution functions independently of the VPN connection, ensuring that users are safeguarded against malicious content regardless of their ability to connect to the on-premises web proxy.
Conclusion
The installation of a host-based content filtering solution is the most effective response to ensure web protection for remote users, particularly when the Always On VPN fails. Other options either do not directly address the protection needs during VPN outages or could introduce additional security risks. Thus, D is the definitive answer in this scenario.
