Key Parts of the Rule
To follow this rule, you should have clear plans and policies. To continually improve, you need to decide four things about your security communication:
- What to talk about. This includes things like your security rules, goals, and any changes.
- When to share this information. For example, you might share updates once a month or right after a security problem.
- With whom to talk. This means both people inside and outside your company, like staff, customers, and partners.
- How to share the news. You might use emails, meetings, or a company website.
How to Meet the Rule
To meet this rule, you should make a communication plan. This plan should list who needs to know what and how you’ll tell them. It’s a good idea to keep records of your communications. This shows that you are following your plan.
A good communication plan helps everyone understand why security is important. It helps people know what to do if something goes wrong.
What an Auditor Will Check
An auditor will want to see proof that you are following these rules. They will:
- Check your communication plan.
- Look for proof that you actually sent the messages.
- For example, they might ask to see emails or meeting notes.
