What
Research into Defending Automobiles Via Intrusion Detection Systems (IDS)

Description

Modern automotive buses were designed for reliability rather than security. This lack of security means that any node on the bus can transmit a message to any other node and the receiver cannot verify the sender or that the message is unaltered. This presentation will discuss strategies to secure vehicle busses using Intrusion Detection Systems (IDS), with a focus on the Controller Area Network (CAN) bus. An overview of IDS concepts will be reviewed along with SwRI’s specific implementation, challenges that were faced, and the evaluation results. The developed IDS uses digital fingerprinting and application layer detection algorithms to identify anomalies. Bus segmentation is used to isolate agitating nodes and remove anomalous messages.
