It will then step through a series of strategies for designing \"Rings of Defense\" around your corporate networking and SCADA infrastructure. The section on \"Developing a SCADA Security Strategy\" has been compiled through many sources, and these strategies can be considered as \"Best Practices\". This paper will then describe specific threats to SCADA Systems and some sample hacking scenarios, and then rank these threats in a security matrix. The following sections after the security matrix describe why security for SCADA systems and control systems are typically overlooked, and what steps should be taken when considering SCADA Security.","PeriodicalId":294424,"journal":{"name":"2nd ISA/IEEE Sensors for Industry Conference,","volume":"259 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121441667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper will discuss the fabrication of the stress sensitive wires. A direct current, galvanostatic electrodeposition process, utilizing an aqueous sulfate-chloride electrolyte, was used to deposit the soft-magnetic, NiFe alloy thin films onto 0.125-mm diameter wires. This current investigation focused on elucidating the deposition parameters required for obtaining suitable NiFe thin films. A photolithographic technique was used for masking the wires and selectively depositing the NiFe films. Electrodeposition parameters were established that yielded extremely fine crystallites that were strain sensitive in the operational load range intended for the sensors.","PeriodicalId":294424,"journal":{"name":"2nd ISA/IEEE Sensors for Industry Conference,","volume":"694 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133322506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensor is implemented using a full planar microstrip technology. The near fields of the ring resonator interact with the material under test (MUT) and the electrical characteristics of the resonator change. A scalar network analyzer is used to measure the resonant frequency and the corresponding amplitude of the transmission parameter for the fundamental mode. The complex permittivity is estimated by inverting the measured parameters using by an algorithm based on Artificial Neural Network (ANN). The proposed sensor is extremely compact and guarantees a good accuracy for low permittivity material. The design procedure is described and experimental results are reported validating the sensor performance.","PeriodicalId":294424,"journal":{"name":"2nd ISA/IEEE Sensors for Industry Conference,","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130257752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also the admittance of the differential type actuator is derived taking the practical conditions into consideration, although it has no admittance in ideal case. It is shown as a function of biasing error, driving error, and capacitive mismatch including parasitic capacitors. The validity of the admittance model is proved by comparing between the admittance model and the measured data. At the end, the distortion in the frequency response curve measured by a capacitive sensor is analyzed and it is concluded that the admittance of the actuator is the main cause of this distortion.","PeriodicalId":294424,"journal":{"name":"2nd ISA/IEEE Sensors for Industry Conference,","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122388488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
