Clock synchronization: how to answer it in a security questionnaire

Usually asked as: “How are the clocks of your processing systems synchronized to a reliable and auditable time source?”

Updated

What the buyer is really asking

Logs from different systems only line up if their clocks agree. Name the time source your systems use. On major cloud providers this is usually handled for you.

Other ways buyers ask it

Every one of these wants the same answer:

  • “How are system clocks synchronized?”
  • “Do you use NTP?”
  • “What time source do your systems use?”

Evidence to have ready

  • Your cloud provider's time service documentation
  • Host or container time configuration

How Tyrvar answers this

Tyrvar treats every wording above as one question. You write the answer once, attach the evidence, and revisit it when your setup changes. Each buyer gets that approved answer no matter how their questionnaire words it. If you have not answered it yet, Tyrvar flags the question for you and does not make something up. Try it on your own questionnaire.
