A security framework for networked RFID

In the last decade RFID technology has become a major contender for managing large scale logistics operations and generating and distributing the massive amount of data involved in such operations. One of the main obstacles to the widespread deployment and adoption of RFID systems is the security issues inherent in them. This is compounded by a noticeable lack of literature on how to identify the vulnerabilities of a RFID system and then effectively identify and develop counter measures to combat the threats posed by those vulnerabilities. In this chapter, the authors develop a conceptual framework for analysing the threats, attacks, and security requirements pertaining to networked RFID systems. The vulnerabilities of, and the threats to, the system are identified using the threat model. The security framework itself consists of two main concepts: (1) the attack model, which identifies and classifies the possible attacks, and (2) the system model, which identifies the security requirements. The framework gives readers a method with which to analyse the threats any given system faces. Those threats can then be used to identify the attacks possible on that system and get a better understanding of those attacks. It also allows the reader to easily identify all the security requirements of that system and identify how those requirements can be met.

More rapid and severe disease outbreaks for aquaculture at the tropics : implications for food security

1. Aquaculture is replacing capture fisheries in supplying the world with dietary protein. Although disease is a major threat to aquaculture production, the underlying global epidemiological patterns are unknown. 2. We analysed disease outbreak severity across different latitudes in a diverse range of aquaculture systems. 3. Disease at lower latitudes progresses more rapidly and results in higher cumulative mortality, in particular at early stages of development and in shellfish. 4. Tropical countries suffer proportionally greater losses in aquaculture during disease outbreaks and have less time to mitigate losses. 5. Synthesis and applications. Disease can present a major problem for food production and security in equatorial regions where fish and shellfish provide a major source of dietary protein. As the incidences of some infectious diseases may increase with climate change, adaptation strategies must consider global patterns in disease vulnerability of aquaculture and develop options to minimize impacts on food production.
