Annex A 5.19 is a preventive control that ensures you maintain an agreed level of information security in supplier relationships.

ISO 27001 Annex A 5.19 Definition

Implementation Guide

We are going to rely on a couple of mechanism to ensure Information Security In Supplier Relationships.

Topic Specific Policy

The standard requires a topic specific policy on supplier relationships – Third Party Supplier Policy

Supplier Management Process

You will need a supplier management process that sets out

  • how to identify and document suppliers and supplier types
  • evaluating suppliers according to information process, transmitted or shared
  • reviewing the controls that are in place
  • documenting what suppliers can access, monitor, control and use
  • assessing and managing supplier risks
  • monitoring and ensuring compliance to information security
  • implementing mitigation for non compliance of a supplier
  • the handling of incidents
  • availability, business continuity and disaster recovery
  • managing the transfer of information
  • the process for terminating and ending a supplier / supplier relationship
  • what level of security of people and physical security are expected

ISO 27001 Supplier Register

The best way to manage ISO 27001 Suppliers is via the ISO 27001 Supplier Register. You can learn more in the ISO 27001 Third Party Supplier Register Beginner’s Guide

Supplier Agreements / Contracts

The number one recommendation is to seek professional legal counsel for the provision of all contracts. The following is guidance but you should always defer to professional legal counsel. Always. You are not a lawyer. We are not a lawyer.

Our first line of defence and go to is the supplier agreement or supplier contract. At its core it is a legal mechanism that is legally binding and provides the greatest level of overall protection.

  • It sets out what is required, what will be done, who will do it, what happens if things go wrong.
  • What information is to be provided, accessed and the methods of access.
  • Legal, regulatory and contractual requirements. Elements such as intellectual property rights, copyright information, data protection requirements.
  • The controls and levels of controls that are required by both parties to the agreement.
  • Acceptable and unacceptable use of assets.
  • How to grant and remove access
  • Penalities, indemnities and remediation for failings to meet the contract.
  • Contact information
  • Screening requirements for staff were legally enforceable.
  • How evidence and assurance of information security will be provided
  • Rights to audit
  • How to solve problems or conflicts with the contract
  • Appropriate back up, business continuity and disaster recovery
  • The process for change management
  • Physical security as appropriate
  • Information transfer processes
  • Termination clauses and processes
  • Destruction and removal of data processes
  • Handover at the end of the contract

Contracts are kept and recorded in the Third Party Supplier Register. They are reviewed at least annually, based on risk and significant change or event.
