Fix Recommendation

Implement and configure the Juniper SRX to fail closed, thus preventing traffic from flowing through without filtering and inspection. In case of failure, document a process for the Juniper SRX to be configured to fail closed. Redundancy should be implemented if failing closed has a mission impact.

Check Contents

Request documentation of the architecture and Juniper SRX configuration. Verify the site has configured the SRX to fail closed, thus preventing traffic from flowing through without filtering and inspection.
