Abstract:
The paper presents and evalutes one of the most important aspects in an information and communication technology system that is to preserve the information from any attacks trying to ensure the protection of data while maintaining quality of service, confidentiality, availability and integrity. In recent years, the process towards convergence has been devoloped to take into account several evolving trends and new challenges. Most of this is about security. New security issues make it necessary to analyse and manage the safety of the information and communication systems. Thus, an economic investment can not ignore the technical evaluation of the system, vulnerabilities analysis, threats taxonomy, and the estimate of expected risk, in order to ensure proper countermeasures to limit the technological and economic damage over time. Risk analysis involves the technical, human and economic aspects, to guide strategy of investment. Following a bio-inspired approach, this analysis requires knowledge of the failure time distribution and survivor analysis to estimate risk. With this paper, we propose a step-by-step analysis based on bio-inspired models, showing and validating that the risk in the absence of explanatory variables that influence the impact of threats, and neglecting the possible relationships between them, does not change shape.
