This was on my exam today. Network segmentation is correct. I passed with 811 score.

Question is asking you prevent further spread, not future solution. So ans is B

Isolating the infected attachment directly addresses the current threat and helps mitigate further spread of the worm, making D the best choice.

The most effective approach in this situation is to quarantine the infected attachment to stop the worm from spreading further. Quarantining the infected attachment allows the analyst to control the threat and stop it from impacting other systems within the network.

Worms are self replicating, and it was already opened..so the genie is out of the bottle already. So you cannot isolate the attachment because replication is in progress..Segmentation is best

Steps to worm mitigation 4 steps to respond to a worm attack Step 1: Containment The first step in mitigating a worm attack is to move swiftly to contain the spread of the worm and determine which machines are infected, and whether these devices are patched or unpatched. Infected machines must be isolated from machines that are not yet infected. Step 2: Inoculation Once it is clear which parts of the network the worm has infected, and those parts have been contained, other vulnerable systems must be scanned and patched. Patching the vulnerabilities the worm is using to spread will help contain the attack.

ChatGPT has no stability changing answer frequently based on situation and fact provide. We should not rely fully on ChatGPT; needs to a bit more research on certain situations

Implementing network segmentation can effectively contain the spread of the worm by isolating the infected system or segment from the rest of the network. This prevents the worm from propagating to other parts of the network and helps mitigate the impact of the incident. Network segmentation is a proactive approach to prevent lateral movement of malware within the network. While isolating the infected attachment (Option D) can be useful, it might not be as effective in preventing the worm from attempting to spread through other means or vectors beyond the isolated system. Implementing network segmentation provides a broader approach to isolating the affected systems and reducing the potential attack surface for the worm.

Implementing network segmentation through firewalls would be the best option. Skip to 4:35 in Professor Messer's Video: https://www.youtube.com/watch?v=L7cwUYl8gYo

"prevent further spread" I choose B. Implement network segmentation

The best course of action for the analyst to take in this situation would be to isolate the infected attachment (option D). By isolating the infected attachment, the analyst can prevent further spread of the worm within the network.
