Vol: 4(4) No: 1 / March 1994 Security Issues in Distributed Computing Systems Sergiu Dascalu Politehnica University of Bucharest, Faculty of Control and Computers, Sp. Independentei 313,Bucharest, Romania Arun R. Sathnur School of Computer Science, Tehnical University of Nova Scotia, P. O. Box 1000,Halifax, Nova Scotia, B3J 2X4, Canada Keywords: computer security, distributed computing Abstract The aim of this paper is to provide an overview of the most important security aspects of the computing systems and to examine some recent solutions designated to ensure computer security. Emphasis is given to the increasingly expanding distributed systems and in this respect, new approaches of the security problems brought by the development of modern computing systems such as networks, wireless LANs, multimedia systems and electronics identification systems are discussed. Several new proposed security tools and techniques are also surveyed. References [1] B. Menkus, Introduction to Computer Security, Computers & Security, 11 (2) (1992) 121-127. [2] B.
