Example ADS entry
Network - Suspicious Network Activity - SMB
Worm Behavior
Goal
Detect SMB Worms by the firewall deny messages they generate
Categorization
These attempts are categorized as Scanning / Network Service
Scanning (T1046)
Strategy Abstract
The strategy will function as follows:
•Look for traffic blocked by the firewalls bound for destination port 445
•Count the number of destination hosts a source tried to reach
•Validate the source is a Company asset, not external
•Alert if the number of targets exceeds NNN in under MMM minutes
Technical Context
<...>
• Blind Spots and Assumptions
• False Positives
• Validation
• Priority
• Response
