IEC 61508 doesn't, yet. There are strong efforts done to keep the two issues separated. Probably for legal and liability issues.

IMHO the two subject intersect (not tp say collide), one being a 2 dimension matrix (probability x consequence), the second one a 3 dimension (probability x consequence x attacker) as modelled by the NSA.

I have strong doubts, that technically, if you still can address when subject by the lines (safety functions) and another one by the columns (firewalls, conduits, zones, etc...) there will be nothing to do (and standardise) at the intersection...

Is this just a terminology issue? It seems to me that it has a profound effect on a safety case if you accept that the probability of catastrophic failure depends mostly on how much someone wants to cause that failure, rather than on how you developed the system.

For example, does IEC 61508 have anything to say about the insider threat?
