Using Cyber Security Evaluation Tool (CSET) for a Wastewater Treatment Plant
This presentation will provide information on the assessment process and ultimate recommendations for the new SCADA system at the water treatment plant located in Manchester, CT. The assessment was completed in the Fall of 2011. The current SCADA system is to be upgraded as part of a $60 million renovation project which is currently under way at the plant. The need for better cyber security was realized during an incident a few years ago that required the resources of plant staff and the Town Information Services (IS) Department. The presentation will focus on the resources utilized to complete the evaluation tool as well as discuss some issues that arose during the process.
Abstract Many human operations have created a large population of small orbital debris in near Earth environment. The threat they represent for satellites is a major factor for the preparation of future space missions. Several experiments devoted to the study of this environment, as well as various materials exposed to space, have been retrieved in the past few years. The analysis of the results shows some differences with previous modeling. Comparison with data from LDEF and from EURECA give some insight in the long term evolution of particle size distribution. Chemical identification of particle remnants inside craters is difficult but provides valuable information on the origin of the impactors. Permanent monitoring of environment is obviously needed, especially for the type of orbits where data are presently scarce ie. heliosynchronous and geostationary orbits.
