Abstract

The existing automotive Controller Area Network (CAN) is vulnerable. The absence of sender verification in its communication means that an attacker acting as a node on its network will be treated like a legitimate node that has always been present, allowing attackers to transmit and receive messages freely. This paper proposes a system that will allow nodes using CAN to identify legitimate messages and reject those that come from illegitimate nodes. In addition, the system provides resistance against replay attacks that can clog up the safety-critical real time networks.

The government intends to rely on an insurance‐based solution to yield risk. Therefore, it is important to identify which characteristics most affect a grower's decision regarding whether or not to use crop insurance. This case study uses California cross‐sectional survey data to directly compare the relative effects of three types of characteristics that are expected to influence insurance preferences. In general, results from the model estimated indicate that preferences for crop insurance are a function of the commodities produced and the risk environment faced by individual growers. © 1996 John Wiley & Sons, Inc.

The variability of producers 'net income levels is largely a function of variability in output price, yield, and input prices. Yet, the tools available to manage price risk and yield risk are not widely used by producers. Is the market failing to provide agricultural producers with effective risk management tools? To identify producers' needs, the paper establishes the relative importance of price and yield risk by decomposing the variability of revenues from a sample of crops in California agriculture. The risk tools available to producers of those commodities are compared to producers needs for tools. Results indicate that "market failure" is readily apparent in markets for tools to manage risks. However, the nature of these missing or incomplete markets does not necessarily imply inefficiencies that would justify government intervention.

Vehicles made within the past years have gradually become more and more complex. As a result, the embedded computer systems that monitor and control these systems have also grown in size and complexity. Unfortunately, the technology that protects them from external attackers has not improved at a similar rate. In this paper we discuss the vulnerabilities of modern in-vehicle networks, focusing on the Controller Area Network (CAN) communications protocol as a primary attack vector. We discuss the vulnerabilities of CAN, the types of attacks that can be used against it, and some of the solutions that have been proposed to overcome these attacks.

The demand for cybersecurity professions faces continual shortages. Real-world cyber threats continue to drive this demand as we face a daily barrage of attacks on our critical infrastructure, national, and private industry assets. To meet this demand, many cybersecurity and information assurance educational programs have emerged. These programs range from specialized tracks within traditional academic programs to specialized degree titles developed solely for the purpose of producing cyber capable graduates.In this paper we document curriculum development that focuses on a systems level approach to cyber assurance education. This program incorporates both hardware and software aspects to ensure cyber security graduates are produced that can address adversaries that target complete system implementations.
