Description

This course will show you how to implement risk analysis and software reliability/availability techniques. It will allow you to meet the main software security requirements and to carry out these activities through practical cases.

Who is this training for ?

For whom ?

Developers, project managers, validation managers faced with the development of critical systems requiring a strong software component.

Prerequisites

Training objectives

Understand the principles and approach to software risk and reliability analysis Understand the stages and components of a software Operational Safety system Analyze a program, in order to check the coding rules, from a perspective software reliability Carry out an analysis of the Effects of Software Errors (AEEL), applying the phase-by-phase approach
