Gabby wants to protect a legacy platform with known vulnerabilities. Which of the following is not a common isolation or segmentation option that could be used to address this issue?
Answer Options
Disconnect it from the network.
Place the device behind a dedicated firewall and restrict inbound and outbound traffic.
Rely on the outdated OS to confuse attackers.
Move the device to a protected VLAN.
Correct Answer: C
Explanation
Relying on an outdated OS to confuse attackers is not a common isolation or segmentation option used to protect vulnerable legacy platforms. Many organizations have legacy platforms in place that cannot be patched or upgraded but that are still an important part of their business. Security professionals are often asked to suggest ways to secure the systems while leaving them operational. Common options include moving the devices to an isolated virtual LAN (VLAN), disconnecting the devices from the network and ensuring they are not plugged back in, and using a firewall or other security device to ensure that the legacy system is protected from attacks and cannot browse the Internet or perform other actions that could result in compromise.
