Series: New Controls in ISO/IEC 27001:2022 Annex A

ICT Readiness for Business Continuity

In this article series, we are analyzing the implementation aspects of the 11 new controls of ISO/IEC 27001:2022 Annex A. The third article explores Control 5.30 (ICT readiness for business continuity).

Control

Control 5.30 (ICT readiness for business continuity) defines the best practices for planning, implementing, maintaining and testing ICT readiness to ensure the availability of the organization’s assets during any disruption.

Attributes

This control would help an organization ensure the continuity of its business operations by implementing corrective actions in response to any disruption. The actions would guarantee the availability of critical assets and prove the resilience of the organization in the face of unforeseen events.

Implementation

The organization should perform Business Impact Analysis (BIA) to identify the ICT continuity requirements. The BIA should determine the ICT resources that will be needed to support the activities for business continuity depending on the magnitude and duration of the probable impacts.

The organization should define ICT continuity strategies that specify the options that will be available before, during and after disruption. Based on these strategies, the organization should implement plans to ensure the required availability of ICT services (within a pre-determined time-frame) when there is interruption to, or failure of, critical processes. The plans should include the following: performance and capacity specifications to meet the business continuity requirements; Recovery Time Objectives (RTO) of the ICT services; and Recovery Point Objectives (RPO) of the ICT information resources. The organization should ensure that competent persons are available to implement the ICT continuity plans.

Artefacts

The contents and implementation of the following security policies and procedures may be impacted by the above control:

• Business Continuity Policy – This policy establishes a systematic approach for business continuity; creates awareness about the business continuity aspects of ISMS and its importance; and defines best practices for testing and reviewing the business continuity plan of the organization.

• ICT Continuity Plan – This plan addresses the organization’s approach to maintaining ICT operations during disruptions, defining relevant roles, responsibilities and procedures.

• Disaster Recovery Policy – This policy details the procedures for recovering from major disruptions, including data backup and restoration, system recovery and communication protocols.

• Incident Response Procedure – Procedures for the detection and containment of, and recovery from, security incidents should be established.

• Change Management Policy – This policy ensures that changes to ICT systems are properly assessed for their impact on business continuity and that appropriate measures are taken to mitigate risks.

• Internal Audit Report – Internal audits should check for readiness of ICT services and resources for ensuring business continuity.
