scope:

This Technical Report gives guidance on the use of IEC 62443 (all parts) related to those aspects of security threats and vulnerabilities that could influence functional safety implemented and realized by safety-related control systems (SCS) and could lead to the loss of the ability to maintain safe operation of a machine.

NOTE 1 For example, an attack on a machine (safety function) such that it affects the availability of the machine and can result in a safety function being bypassed.

Considered security aspects of the machine with potential relation to SCS are:

- vulnerabilities of the SCS either directly or indirectly through the other parts of the machine which can be exploited by security threats that can result in security attacks (security breach);

- influence on the safety characteristics and ability of the SCS to properly perform its function(s);

- typical use case definition and application of a corresponding threat model.

NOTE 2 For other aspects of security threats and vulnerabilities, the provisions of the IEC 62443 (all parts) can apply.
