Popis:	FTA (Fault Tree Analysis) is one of the most used methods for reliability analysis and to quantify the risks associated with the failures of systems. This method performs analysis of the combination of events that can lead to a critical system failure (called Top Event of the designed Fault Tree) and allows calculating the probability of failure. In this paper, has been built the Fault Tree for a Web server considering failures that may occur at hardware level (the basic components for the considered computer system). After realizing the Fault Tree, two types of analysis were made: qualitative (which led to the identification of minimal cut sets) and quantitative (this allowed the calculation of the probability of occurrence of the considered critical event - “Web server not operational”).
