The full story:

On Feb 15, 2022, the International Organization for Standardization (ISO) released the new ISO/IEC 27002 standard. The updated standard revises the guidance around implementation of the Annex A controls related to the Information Security Management System (ISMS) certification for ISO/IEC 27001.

For companies that are currently certified, there is a 3-year transition period to adopt the new standard. This aligns with the certification cycle for ISO/IEC 27001 certifications being valid for 3 years.

Why you should care about ISO/IEC 27002

ISO/IEC 27002 are the instructions for your ISO/IEC 27001. The ISO/IEC 27001 is still the actual standard; however, ISO/IEC 27002 provides detailed guidance on how to determine and implement controls for related information security risks to meet the requirements of the standard based on Annex A.

What has changed in the new standard?

At a high level, the control sets were reorganized into 4 categories (Organizational, People, Physical, and Technological), when previously there were 14 control domains. The total number of Annex A controls was reduced from 114 to 93, with much of the reduction related to the removal of redundant controls as 57 controls were merged and reduced to 24 controls.

In addition to reducing the number of controls in certain areas, 11 new controls were added. Below is a breakdown of the new controls:

  • A5 – Organizational Controls
    • 7 – Threat intelligence: Information relating to information security threats should be collected and analyzed to produce threat intelligence.
    • 23 – Information security for use of cloud services: Processes for acquisition, use, management and exit from cloud services should be established in accordance with the organization’s information security requirements.
    • 30 – ICT readiness for business continuity: ICT readiness should be planned, implemented, maintained and tested based on business continuity objectives and ICT continuity requirements.
  • A7 – Physical Controls
    • 4 – Physical security monitoring: Premises should be continuously monitored for unauthorized physical access.
  • A8 – Technological Controls
    • 9 – Configuration management: Configurations, including security configurations, of hardware, software, services and networks should be established, documented, implemented, monitored and reviewed.
    • 10 – Information deletion: Information stored in information systems, devices or in any other storage media should be deleted when no longer required.
    • 11 – Data masking: Data masking should be used in accordance with the organization’s topic-specific policy on access control and other related topic-specific policies, and business requirements, taking applicable legislation into consideration.
    • 12 – Data leakage prevention: Data leakage prevention measures should be applied to systems, networks and any other devices that process, store or transmit sensitive information.
    • 16 – Monitoring activities: Networks, systems and applications should be monitored for anomalous behavior and appropriate actions taken to evaluate potential information security incidents.
    • 23 – Web filtering: Access to external websites should be managed to reduce exposure to malicious content.
    • 28 – Secure coding: Secure coding principles should be applied to software development.

The bottom line

With the comprehensive ISO/IEC 27002 standard, companies should perform a risk analysis to help ensure that their risk management and ongoing monitoring aligns to the new requirements.
