Abstract:
In this paper a comparative study is made between Safety-Critical Applications and Information Systems. These kinds of systems have the need for protection, each against specific kinds of problems. In both types of applications, it is necessary to adopt measures to assure their perfect operation, safety and security, preventing dangerous situations. The main concepts of these two kinds of applications are presented and compared. The techniques to guarantee systems safety and security are also considered. The purpose of this paper is to show that it is possible to combine those techniques, forming a unique set for safety and security guarantee.
