Abstract
There is a long tradition at machinery sector to make
risk assessments considering safety issues. Currently,
the assessment is made usually according to ISO 12100 and
if the focus is on control systems then often according
to ISO 13849-1. Cyber security issues have emerged to
publicity mainly because of the threat associated to
money and confidentiality. It is evident that security
may affect also safety. Therefore, machine builders have
increased their interest in security issues also. Current
paper is related to cases where cyber security issues may
have an effect on machinery safety. There are already
several standard proposals related to the connection
between cyber security and safety, but the field is still
evolving. The idea is that security issues must not
impair safety, but on the other hand, the required
resources must be in line with the risk.
The paper addressed the needs to combine risk assessments
to cover both safety and related cyber security issues.
The security issues covered in this case are then limited
to safety functions of control systems, communication,
safety of machinery misuse (interfaces) and other
safety-related situations that are found rare but
possible.
