10 Set up policy , procedures and Documented Information to control risks

For each control that you define, you must have corresponding statements of policy or in some cases a detailed procedure. The procedure and policies are used by affected personnel so they understand their roles and so that the control can be implemented consistently. The documentation of the policy and procedures is a requirement of ISO 27001.
What you will need:
To help you identify which procedures you might need to document, refer to your Statement of Applicability. To help you write your procedures so that they are consistent in content and appearance, you might want to create some type of template for your procedure writers to use.
Results:
Additional policy and  documented Information. (The number of documents you produce will depend on the requirements of your organization.) Some of these procedures might also generate records. For example, if you have a procedure that all visitors to your facility must sign a visitors log, the log itself becomes a record providing evidence that the procedure has been followed.
Example:
The number of policies, procedures, and records that you will require as part of your ISMS will depend on a number of factors, including the number of assets you need to protect and the complexity of the controls you need to implement. The example that follows shows a partial list of one organization’s set of documents:

Mandatory documents and records required by ISO 27001:2013

  • Scope of the ISMS (clause 4.3)
  • Information security policy and objectives (clauses 5.2 and 6.2)

  • Statement of Applicability (clause 6.1.3 d)
  • Risk treatment plan (clauses 6.1.3 e and 6.2)
  • Risk assessment report (clause 8.2)
