Potential false positivesedit

Route Tables may be created by a system or network administrators. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Route Table creation by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule. Automated processes that use Terraform may lead to false positives.
