1.4 Impact of security on safety

Contextual description: Security is concerned with the prevention of loss arising from malicious causes. Security often focusses on loss of data or financial loss, and as such security assurance in general is not the focus of the BoK. However, security attacks on a system may also impact the safety of that system by giving rise to hazards. It is therefore important that the contribution of security is considered as part of the safety assurance process.

All systems are vulnerable to security attacks to some extent, however the nature of many RAS makes them particularly vulnerable, and may introduce a number of unique security challenges. It is important that the effects of security are considered throughout the safety assurance process

Practical guidance: General guidance on the nature of security threats for RAS. Specific guidance on the impact of security threats and how they should be considered will be provided against the particular assurance objectives.
