People are becoming aware of how much information is publicly available, as stories in the national news media discuss the ease with which hackers steal identities. On a less personal note, compromises of information involving authorized access show that organizations have information security problems. With this awareness has grown an understanding of our dependence on accurate, confidential information, and of the fragility of the infrastructure we use to secure that information. Of all the questions emerging, the fundamental one is this: how can we secure information? This essay discusses different forms of education that are relevant to this problem.","PeriodicalId":282630,"journal":{"name":"IEEE Concurr.","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122551863","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}

Object-oriented technology, however, can help simplify the development, maintenance and reuse of applications for manufacturing and process control, just as it has helped simplify the development, maintenance and reuse of other applications. The Java Devices for Process Control (JDPC) Project, which operates at the University of Catania, is developing a field device, called the Java Microcontrolled Device (JMD), that is capable of running process control applications written in Java. The JMD runs a Java-based kernel that provides Java applications with a set of primitives which are suitable for implementing control algorithms. This article describes the JMD's architecture and functionality. Implementing the JMD represents one of the first steps toward fully incorporating Java into process control and manufacturing environments.","PeriodicalId":282630,"journal":{"name":"IEEE Concurr.","volume":"32 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115815990","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}
