I want to create a custom rule within the Firepower Management Center that triggers when there are multiple failed RDP login attempts. I am using an existing rule as a template and I have created the rule in the attached screenshot. I am basing the rule on 10 failed login attempts in 60 seconds and the TCP Rst flag. So, I believe I have the detection_filter option correct. But, I have a question about the metadata option which is from the existing rule I am using as a template. What does "policy max-detect-ips drop" mean? Is there any documentation about this option and what can be used and what it means? Are there any other options I need to add for this rule?
