Abstract
A computer includes a processor and a memory connected to the processor. The memory stores instructions executed by the processor to augment a message with network node attributes derived by linking from an original network node specified in the message to additional network nodes associated with the original network node. Message signatures representing the network node attributes are generated. The message signatures are evaluated to characterize the message.
