A network management system includes a processor and a memory that is accessible by the processor. A computer program is embedded within the memory. The computer program includes instructions to detect the receipt of one or more modified management messages. Each of the one or more modified management messages includes one or more modified data packets having a unique identifier. The computer program further includes instructions to determine an originating device associated with each of the unique identifiers. In a particular embodiment, the unique identifier is a predetermined device management password. Further, the predetermined device management password is a community string for a simple network management protocol data packet.
