Annex A 5.21
Managing information security in the ICT supply chain
Risks associated with the ICT supply chain, including a supplier's own suppliers, are managed.
What an assessor looks for
Expect questions about sub-processors and about components inside products you buy. Knowing who your suppliers depend on is the substance here.
Where it usually fails
Direct suppliers are assessed and no visibility exists beyond the first tier, so concentration risk is unknown.
