This Technical Report recommends a defined format for the distribution of information aboutsecurity patches from asset owners to IACS product suppliers, a definition of some of theactivities associated with the development of the patch information by IACS product suppliersand deployment and installation of the patches by asset owners. The exchange format andactivities are defined for use in security related patches; however, it may also be applicablefor non-security related patches or updates.

The Technical Report does not differentiate between patches made available for the operatingsystems (OSs), applications or devices. It does not differentiate between the productsuppliers that supply the infrastructure components or the IACS applications; it providesguidance for all patches applicable to the IACS. Additionally, the type of patch can be for theresolution of bugs, reliability issues, operability issues or security vulnerabilities.

NOTE 1 This Technical Report does not provide guidance on the ethics and approaches for the discovery anddisclosure of security vulnerabilities affecting IACS. This is a general issue outside the scope of this report.

NOTE 2 This Technical Report does not provide guidance on the mitigation of vulnerabilities in the periodbetween when the vulnerability is discovered and the date that the patch resolving the vulnerability is created. Forguidance on multiple countermeasures to mitigate security risks as part of an IACS security management system(IACS-SMS), refer to, Annexes B.4.5, B.4.6 and B.8.5 in this Technical Report and other documents in the IEC62443 series.
