Goal
Detect when 0.0.0.0 is added to the project's IP access list, which allows access from anywhere.
Categorization
https://attack.mitre.org/techniques/T1021/
Strategy Abstract
Atlas only allows client connections to the database deployment from entries in the project's IP access list. Detect when 0.0.0.0 is added to that list, which allows access from anywhere.
Technical Context
Allow access to project from anywhere to generate relevant logs.
Blind Spots and Assumptions
Assumes proper MongoDB Atlas logging.
False Positives
Could be legitimate administrator activity for specific project.
Validation
Allow access to project from anywhere to trigger alerts.
Priority
Medium
Response
Check if this activity was legitimate. If not, delete 0.0.0.0 from the list of allowed ips.
