Securing the supply chain

Suppliers represent the biggest risk to our organisation in terms of information security.

Suppliers provide us with valuable products, services and resources but they are outside of our control.

We trust them with our most valuable information. We trust them to do the right thing. We trust them with our customers and clients information.

We can protect what we control. We do not control our suppliers.

This is where effective third party supplier management comes in.

The Third Party Supplier Policy sets our how we manage the risk associated with our suppliers.

The Third Party Supplier Register is the tool we use to actively manage them.

What is a supplier register?

The supplier register is a list of all of the suppliers that we have that store, process or transmit data.

For suppliers we are looking to seek a level of assurance they are doing the right thing for information security.

The easiest way to achieve this is to check that we have an up to date and in date:

  • contract that includes clauses for information security and data protection.
  • industry level certification that covers the products and / or services we are buying such as an ISO 27001 certification can provide us with adequate assurance.

The contract and the industry certification is noted and recorded in the supplier register.

We also record what they do for us and how reliant upon them we are.

The supplier register captures key information about the supplier and is used to manage the supplier reviews and supplier assurance processes.

This will lead to how we manage them.

We will know

  • Who our suppliers are
  • What the do for us
  • If we have a contract
  • If they have information security certificates
  • What data we share with them
  • When we last reviewed them and when we will next review them

Third Party Supplier Assurance

The level of assurance we require is based on risk.

Risk is determined by a number of factors including how critical they are to our operation and how much confidence we can evidence that they are doing the right thing for information security.

It may be we add them to the risk register and manage them via risk management.

As part of our assurance we make sure that every supplier in the register should be reviewed at least annually.

We cover how the supplier fits into the information security management system in the ISO 27001 Templates Documents Ultimate Guide.
