Taking the human factor into account
Information security and safety for risk management – Application to embedded and IC systems

In many cases, IT techniques do not offer sufficiently reliable or inexpensive means of preventing certain failure modes from producing the feared events. In such cases, the safety barriers employed call on the operator, putting man back into the safety loop.

However, the human factor also has its failures, and it's important to be able to analyze and even quantify them, to ensure that they really do contribute to the desired improvement in reliability. FOH risk analysis (Organizational and Human Factor) must therefore complement software risk analysis to validate system reliability.
