What is a risk register?

An ISMS risk register is a way to categorise information security risks and forms the backbone of a successful information security management system (ISMS).

A risk register includes a set of risks, each given a risk score, a method of dealing with the risk, and a risk owner within the organisation. Risks are tracked on an ongoing basis by an organisation’s management team in review meetings.

A risk register documents how your organisation has dealt with risk over time and, hopefully, how risk has been reduced through this process.

For ISO 27001 compliance, a risk register is a mandatory document, so critical for businesses to create.

ISMS Risk Register Template

The following considerations should be included in your risk register, and can be used as a starting point or template for creating your own risk register. It’s worth noting that this is not an extensive and all-encompassing risk; there may be industry- or organisation-specific factors that you have to consider, but this is a good starting point.

Your risk register should contain the following:

  • Risk name – This should be clear and not create any doubt or overlap with other risks.
  • Risk description – The description should provide a succinct and clear definition of the risk, pitched at a level relevant to the management team reviewing it.
  • Risk likelihood – All organisations have risks, either internal or external, so this should provide a realistic estimate of the risk’s likelihood of occurring. You can use a 1-5 scale for this.
  • Risk impact – This section concerns the level of impact on your organisation, should the risk occur. Again, you can use a 1-5 scale for this.
  • Risk controls – What controls are currently in place to prevent the risk, or to mitigate the risk, should it occur.
  • Risk owner – Who, within the management team or wider organisation, is responsible for this risk?
  • Risk status – This should cover the current status of this risk on an ongoing basis.

As well as considering these factors, organisations can also use a risk matrix tool, which plots the likelihood of a risk occurring (point 3 above) against its impact (point 4 above).

In a matrix like this, risks are categorised on a sliding scale as follows:

  • Low impact and low likelihood – These are considered low-priority.
  • Low impact but high likelihood – These are considered medium-priority.
  • High impact but low likelihood – These are considered medium-priority.
  • High impact and high likelihood – These are considered high-priority.

ISMS Risk Register Example

In practical terms, an Excel spreadsheet is a perfect format to create and maintain a risk register. Organisations should assign columns for the seven categories listed above, with each risk occupying a separate row.

To effectively maintain a risk register, management should use this risk register document to consistently review the organisation’s information security risks, updating it on an ongoing basis and using it to track how you have dealt with the risks identified.
