16) Has your organisation set Recovery Time Objectives (RTO) and / or Recovery Point Objectives (RPO)?

Answer yes if your organisation has specified Recovery Time Objectives (RTO) and / or Recovery Point Objectives (RPO) for any of your services.

What is the control?

A disaster recovery (DR) plan defines how – and how quickly – you’ll recover from an incident that unexpectedly renders critical services, applications and data inaccessible. As such, it prepares you for recovering from disruptions quickly, so you can minimise the impact to your business operations.

Among the components of a DR plan are two key parameters that define how long your business can afford to be disrupted and how much data loss it can tolerate. These are the Recovery Time Objective (RTO) and Recovery Point Objective (RPO).

  • RTO is the goal your organisation sets for the maximum length of time it should take to restore normal operations following an outage or data loss.
  • RPO is your goal for the maximum amount of data the organisation can tolerate losing. This parameter is measured in time: from the moment a failure occurs to your last valid data backup. For example, if you experience a failure now and your last full data backup was 24 hours ago, the RPO is 24 hours.

Why should I have it?

You will likely create different RTOs and RPOs for the various operations your company uses to process data. The more mission-critical the operation, the lower (closer to zero) the RTO and RPO should be. The less critical the operation, the greater your tolerances will be.

To calculate the right RTOs and RPOs for your organisation, consult with business leaders and senior management to identify those functions and systems that business operations and commercial success depend upon; these are the most important to keep operational and should have low RTOs and RPOs. Once you’ve created this business impact analysis, you can divide your systems into tiers based on levels of criticality and apply appropriate recovery objectives for each tier.

How to implement the control

For SMEs, we recommend that you have an information security consulting firm review your Business Continuity Plan and Disaster Recovery options. They will be able to report on any disruption recovery risks your company is exposed to.
