Around the world, SCADA (supervisory control and data acquisition) systems and other real-time process control networks run mission-critical infrastructure-- everything from the power grid to water ...treatment, chemical manufacturing to transportation. These networks are at increasing risk due to the move from proprietary systems to more standard platforms and protocols and the interconnection to other networks. Because there has been limited attention paid to security, these systems are seen as largely unsecured and very vulnerable to attack. This book addresses currently undocumented security issues affecting SCADA systems and overall critical infrastructure protection. The respective co-authors are among the leading experts in the world capable of addressing these related-but-independent concerns of SCADA security. Headline-making threats and countermeasures like malware, sidejacking, biometric applications, emergency communications, security awareness llanning, personnel & workplace preparedness and bomb threat planning will be addressed in detail in this one of a kind book-of-books dealing with the threats to critical infrastructure protection. They collectivly have over a century of expertise in their respective fields of infrastructure protection. Included among the contributing authors are Paul Henry, VP of Technology Evangelism, Secure Computing, Chet Hosmer, CEO and Chief Scientist at Wetstone Technologies, Phil Drake, Telecommunications Director, The Charlotte Observer, Patrice Bourgeois, Tenable Network Security, Sean Lowther, President, Stealth Awareness and Jim Windle, Bomb Squad Commander, CMPD.* Internationally known experts provide a detailed discussion of the complexities of SCADA security and its impact on critical infrastructure * Highly technical chapters on the latest vulnerabilities to SCADA and critical infrastructure and countermeasures * Bonus chapters on security awareness training, bomb threat planning, emergency communications, employee safety and much more * Companion Website featuring video interviews with subject matter experts offer a "sit-down" with the leaders in the field
The role of krill (Euphausia superba) in influencing the spatial variability of phytoplankton is examined. Data were collected during a cruise of the S.A. Agulhas (10 February - 20 March l981) in the ...area between 15(DEGREES)- 30(DEGREES) east and 60(DEGREES)- 70(DEGREES) south. Krill density and swarm characteristics (number, size, and biomass) were estimated acoustically. Data on phytoplankton biomass, productivity and species composition, together with data on the physico-chemical environment were obtained from discrete water samples collected from either 7 or 8 depths between 0-100 m at a total of 37 stations. Correlation, multiple regression, and canonical analyses are applied to the station data to examine interrelationships between the variables. Phytoplankton biomass is inversely correlated with mean krill density but positively correlated with the biomass of individual swarms. A positive correlation between krill density and the relative amounts of phaeo-pigments in the > 20- m size fraction of phytoplankton suggests that krill selectively feed on larger cells. The application of spectral analysis to continuous horizontal profiles of integrated krill density, surface seawater temperature, and in vivo fluorescence reveals that, over the range of 4-20 km, the variability in phytoplankton biomass is largely determined by physical processes. However, the steepness of the fluorescence variance spectrum relative to the temperature spectrum, together with consistent coherence between the phytoplankton and krill profiles suggest that predator-prey interactions are of importance in determining the distributional patterns of the phytoplankton.
The methylammonium cation in CH3NH3PbI3 demonstrates increasing positional disorder on heating from 100 K to 352 K. In the tetragonal phase, stable between 165 K and 327 K, the cation is disordered ...over four sites directed toward the faces of the distorted cubic PbI3(-) framework and migrates towards the cavity centre with increasing temperature.
