Abstract
A system and method for monitoring data traffic on a MIL-STD-1553 data bus system with a data guard. The monitoring system includes a data guard, which may be toggled between a passive mode and an active mode using two switches. In the active mode, using a first switch, data traffic from remote terminals on the MIL-STD-1553 data bus system are placed on a guarded bus of the data guard system and sent to the data guard by way of a coupler for filtering data messages through a plurality of pre-generated data set rules. If the data traffic is validated, it is returned to the MIL-STD-1553 data bus system through a second coupler. In the passive mode, the data traffic is directed to a transparent bus by way of a third coupler using a second switch, thus allowing the MIL-STD-1553 data bus system to operate without latency concerns.
