Purpose of Control 5.29

Despite the broad range of preventive measures available to organisations that are ISO 27002:2022 adherent, disruptions to business continuity and standard operations can and do occur.

Control 5.29 outlines the operational adjustments that organisations should adopt when experiencing disruption, to safeguard information and protect company assets.

Attributes Table

5.22 is a dual-purpose preventative and corrective control that maintains risk by implementing a plan that enhances information security during periods of disruption, and mitigates damage across organisational assets.

Ownership of Control 5.29

Control 5.29 refers to operational information security process and procedures that are activated once critical events or business disruption occurs.

As such, ownership of Control 5.29 should reside with a member of the senior management teams who oversees the organisation’s day-to-day operations and/or continuity planning contingencies, such as the Chief Operating Officer (COO).

General Guidance on Control 5.29

Control 5.29 stipulates that information security should be a constituent part of an organisation’s broader business continuity management procedure.

Organisations should draw up plans that seek to maintain information security integrity, and subsequently restore it, should information be compromised in any way following operational interruption or systems failure.

Security levels should be restored to levels prior to interruption, and in a timely manner that mitigates any further damage.

In doing so, organisations should:

  1. Deploy and maintain general information security controls, including business systems and ICT platforms contained within the organisation’s broader continuity plans.
  2. Implement processes that seek to maintain information security controls throughout any disruption.
  3. Where relevant, deploy compensating controls for any information security related efforts that are not able to be sustained throughout a period of disruption.

Supplementary Guidance

Control 5.29 acknowledges the highly variable nature of continuity planning, and gives organisations significant leeway to implement information security controls that are specific to the different kinds of business disruption that organisations may experience.

ISO asks organisation to focus on two key areas when formulating a business continuity plan:

a) loss of confidentiality

b) the integrity of information

Changes and Differences from ISO 27002:2013

27002:2022-5.29 replaces the following three controls from 27002:2013:

  • 17.1 – Planning information security continuity
  • 17.1.2 – Implementing information security continuity
  • 17.1.3 – Verify, review and evaluate information security continuity

In recognition of the complex nature of business continuity plans – and how they differ according to various different kinds of interruption – ISO have simplified their guidance by moving away from a granular approach and asking organisations to instead consider a few basic points when drafting subject-specific plans (see above).

For example, part of the guidance within 17.1.2 states that:

“incident response personnel with the necessary responsibility, authority and competence to manage an incident and maintain information security are nominated”.

Despite their importance in effective continuity planning, 5.29 makes no specific mention of incident response teams and trusts the organisation to consider them under all points in the guidance notes, more specifically:

  • Deploy and maintain general information security controls, including business systems and ICT platforms contained within the organisation’s broader continuity plans.
