The firewall implementation must only reveal error messages to authorized personnel.

| Description |
|---|
| If the application provides too much information in error logs and administrative messages to the screen, this could lead to compromise if the information is available to non authorized personnel. If controls are not in place to protect the error message, an attacker could use the information to his/her advantage and compromise the system based on what is known about the error. The structure and content of error messages need to be carefully considered by the organization and development team. The extent to which the information system is able to identify and handle error conditions is guided by organizational policy and operational requirements. |
