TMA-MFD-1.1.3
Disable Serial Connectors
Description
A serial port, such as RS232, is a physical interface, or connection, commonly used to connect computers, peripherals, and other consumer products. These interfaces are often used by legacy MFDs to provide administrative and diagnostic capabilities. It is recommended that serial connectors be disabled, where possible. Serial interfaces that expose administrative functionality may be abused by local attackers to compromise the MFD’s configuration and the data traversing it.
