Suggested answer: C

Explanation:

Segmentation is a technique that divides a network into smaller subnetworks or segments, each with its own security policies and controls. Segmentation can help mitigate network access vulnerabilities in legacy loT devices by isolating them from other devices and systems, reducing their attack surface and limiting the potential impact of a breach. Segmentation can also improve network performance and efficiency by reducing congestion and traffic. Patching, insurance, and replacement are other possible strategies to deal with network access vulnerabilities, but they may not be feasible or effective in the short term. Patching may not be available or compatible for legacy loT devices, insurance may not cover the costs or damages of a cyberattack, and replacement may be expensive and time-consuming.

C. Segmentation Since these are legacy IoT devices, patching may not be immediately available or possible, and replacing them might take time. Segmentation is a quick and effective approach to isolate these vulnerable devices from the rest of the network, limiting the potential impact of the vulnerability. This containment strategy minimizes exposure while a more permanent solution, such as patching or replacement, is pursued.

I believe that the answer is C. If it is *legacy* IoT, that means that support, for said devices, could no longer be available. Hence patches for these devices may not exist or the latest patch available is extremely out of date.

Applying patches or updates is the most effective and immediate way to address known vulnerabilities. This can close security gaps and protect the devices from potential exploitation without needing to replace the hardware or significantly change the network architecture.
