Penetration of ZigBee-based wireless sensor networks

Wireless Sensor Networks are becoming popular as a simple means of collecting data by public utilities, motor vehicle manufacturers and other organisations. Unfortunately the devices on such networks are often insecure by default, which presents problems in terms of the integrity of the data provided across those networks. This paper explores a range of attacks that were successful on a network consisting of nodes using the ZigBee protocol stack and proposes defences that can be put in place to circumvent these attacks thus leading to more secure systems and increasing user confidence

Security aspects of sensor-based defence systems

The Australian Defence Force (ADF) has IMAP and JMAP to perform planning prior to the deployment of forces, but there is a knowledge gap for on-ground forces during the execution of an operation. Multi-agent based sensor systems can provide on-ground forces with a significant amount of real-time information that can be used to modify planning due to changed conditions. The issue with such sensor systems is the degree to which they are vulnerable to attack by opposing forces. This paper explores the types of attack that could be successful and proposes defences that could be put in place to circumvent or minimise the effect of an attack

On the Effectiveness of Intrusions into ZigBee-based Wireless Sensor Networks

Wireless Sensor Networks are becoming popular as a means of collecting data by military organisations, public utilities, motor vehicle manufacturers and security firms. Unfortunately, the devices on such networks are often insecure by default, which creates problems in terms of the confidentiality and integrity of data transmitted across such networks. This paper discusses attacks that were successful on a simple network consisting of nodes using the ZigBee protocol stack and proposes defences to thwart these attacks, thus leading to increased user confidence in the ability of organisations to provide secure and effective services. The outcomes were that it was possible to add false nodes to a test network and have these nodes accepted by the network. This was because the packet encryption available for the devices was disabled by default
