Yes, that's a good point, Garry. We should double-check all the configurations to troubleshoot.

I believe the Group By section must also be checked to ensure it matches the attributes in the Filters section.

Part of the image is missing. To me is the OR operator missing. Probably the ot ports group contains modbus port 502. If the condition is "AND", no packet is matched because modbus port can't be present both in the source and destination port at the same time.

I agree with Donette. The SubPattern should be configured correctly to match the Modbus protocol.

I think the issue might be with the SubPattern filter missing the filter to match the Modbus protocol.

Alright, alright, let's not get too carried away here. I think we've got a pretty good handle on this question, and option D does seem like the most logical answer. Now let's just hope the actual exam is a little more straightforward, huh?

Okay, let's start with option A. The first condition on the SubPattern filter using the OR logical operator? That doesn't sound right to me. Wouldn't that make the rule too broad?

Option B seems like a red herring to me. Why would the attributes in the Group By section need to match the ones in the Filters section? That doesn't seem like a logical requirement for the rule to work properly.

Haha, I bet the exam writers are trying to trip us up with these options. I was also thinking D, but now I'm second-guessing myself. Maybe we're all missing something obvious?

I agree, option D does seem like the most likely answer. If the rule is supposed to monitor Modbus traffic, but it's not triggering any incidents, then the SubPattern is probably not correctly filtering for the Modbus protocol.

Hmm, this question seems a bit tricky. The issue with the rule configuration is not immediately clear to me. I'm leaning towards option D, since the question states that the rule is monitoring the Modbus protocol, but the SubPattern might be missing the filter to match it.
