Annex A 5.20
Addressing information security within supplier agreements
Relevant security requirements are established and agreed with each supplier.
What an assessor looks for
Produce actual signed agreements containing the requirements, not a template. Incident notification timing, sub-processing and audit rights are the clauses most often examined.
Where it usually fails
The clause library is strong and the executed contracts for older suppliers contain none of it.
