Using UML Diagrams For System Safety And
Security Environment Analysis

Abstract
In this paper, the use of UML (Unified Modelling Language) diagrams as
software tools for system safety and security environment analysis is proposed
and evaluated.
The UML diagrams are used to plan and build systems based on the
Object-Oriented approach. As these diagrams allow many system aspect
viewpoints, they also allow a deep analysis and understanding of the system
architecture and implementation details, as well as system functioning and
operational features.
When a system safety/security environment analysis is accomplished, many
aspects of system operation, functioning, data flow, data types, architecture and
implementation details must be well known, understood and modelled in order to
determine possible weak points for the system safety (or security, or both,
depending on the system application). The various UML diagrams supply all the
information needed for a safety/security system analysis and many aspects of the
UML methodology can be applied for the same purpose.
Finally, a case study for an Object-Oriented ATO (Automatic Train
Operation) control system proposed for use on a subway system is conducted in
order to analyse the safety environment and to identify possible risks and danger
situations to the system operation.
This control system proposed was presented and discussed in COMPRAIL
2004, in the paper called \“Object-Oriented Approach for Automatic Train
Operation Control Systems”; now this paper presents a complement of that
study, using the drawn diagrams to make an analysis of the system safety
environment.
