Misconfiguration

The misconfiguration page contains a list of assets with opened port policies that are not allowed to connect to the system.

Any open port that are listed in this policy will make MetaDefender OT Security trigger alerting when the asset has an unwanted port opened.

Each record in the asset list also contains additional rules about:

Misconfiguration policies are added manually by the user.
