One of the most leading security standards did get an updated version in 2022, on October 25. The revision of the ISO 27001:2022 version has only gotten a few updates, but it is also important to look at them and study them closely.
In this article, let’s talk about the major changes made in ISO 27001:2022 vs 2013
ISO 27001 is an information security management system (ISMS) that provides a framework for organizations to manage and protect their sensitive information. The International Standard Organization (ISO) first introduced this standard. ISO is a non-governmental organization that develops international standards for various industries. The British Standards Institution (BSI), which published the earlier BS 7799-2 standard in 1999, replaced it with ISO 27001 in 2005. All types and sizes of organizations can use ISO 27001, a globally recognized standard for information security management. ISO 27001 gives a systematic approach for managing sensitive information, which also includes risk management processes, policies, and procedures and the implementation of controls to get rid of risks that are noticed.
HISTORY OF ISO 27001 AND ISO 27002
Both ISO 27001 and ISO 27002 are internationally recognized standards related to Information Security Management.
ISO 27001, which is also called “information security management systems,” was first published in 2005. The British Standard Institution (BSI) initially released it in 1999. BS 7799-2 provides guidelines for establishing, implementing, maintaining, and improving an ISMS. The International Organization for Standardization (ISO) adopted BS 7799-2 as ISO 27001 in 2005, following the global recognition of information security. ISO 27001 underwent revisions in 2013 and 2022 to address evolving security challenges and align with the other management system standards under Annex SL.
ISO 27001 helps organizations constantly improve their ISMS. It sets out the requirements for identifying information security risks, implementing controls, and monitoring the effectiveness of the system. In 2005, ISO/IEC 17799 was reissued as ISO/IEC 27002 to align with the newly adopted ISO 27001 Standard. The purpose of ISO 27002 is to provide a comprehensive set of best practices and guidelines for information security controls. It covers various areas of information security, including organizational security, asset management, human resources security, physical and environmental security, communications and operations management, and more. Unlike ISO 27001, ISO 27002 is not a mandated standard. Instead, it acts as a guide that companies may use to choose and put into place the best security measures in accordance with their unique demands, risks, and legal and regulatory requirements.

COMPARING ISO 27001:2013 vs. 27001:2022:
In this comparative analysis, we will explore and compare ISO 27001:2013 and ISO 27001:2022, highlighting the potential changes, enhancements, and implications of the newer version. By examining the key differences between these two versions, organizations can gain insights into how the standard has evolved and understand its potential impact on their information security management practices. We will delve into the revised structure, modified requirements, updated controls, and any new additions or deletions.
Let’s check out the major changes that have been made in ISO 27001:2022 compared to the 2013 revision.
Old revision (2013):
The ISO 27001:2013 revision was published on September 25, 2013. This revision consists of a set of principles and orders; we will check them out.
- ISO 27001:2013 consists of 10 clauses in the main part of the ISO standard, which include introduction, scope, normative references, terms and definitions, context of the organization, leadership, planning, support, operation, performance evaluation, and improvement.
- In ISO 27001:2013, Annex A contains a list of 114 security controls that can be selected and implemented to address information security risks.
- These sections are divided into 14 domains.
New revision (2022):
The ISO 27001:2022 revision has gone through a few major changes in 2022 compared to its predecessor. They are:
- Reduced Control Count: ISO 27001:2022 presents 93 controls, a decrease from ISO 27001:2013’s 114.
- Revised Control Grouping: ISO 27001:2022 organizes these controls into 4 ‘themes’ instead of 14 clauses. I.e., People (8 controls), Organizational (37 controls), Technological (34 controls), Physical (14 controls)
- Additions to Controls: ISO 27001:2022 introduces 11 new controls.
- Enhanced Control Categorization: The controls in ISO 27001:2022 now feature five attribute types for improved categorization.
CHANGES MADE IN THE ISO 27001 MANAGEMENT SYSTEM IN 2022
The obligatory clauses 4 through 10 have undergone relatively minor wording revisions to better conform to Annex SL, ISO 9001, ISO 14001, and other ISO management standards. The number of controls has decreased from 114 to 93. Of the overall number of controls, 35 have remained the same, 23 have had their names changed, and 57 have been combined. Two different controls were created from one control. To handle new IT and security trends, 11 additional controls have also been developed.
On August 15, 2021, ISO 27001:2022, the most recent revision, was made public. We will get to know the ISO 27001 difference between 2013 and 2022. Following are the primary variations between ISO 27001:2013 and ISO 27001:2022:
- Clause 4.2: Now includes item (c), which calls for a study of which of the interested parties’ criteria the ISMS must adhere to.
- Clause 4.4: Requires an organization to have an information security management system that is established, implemented and continually improved.
- Clause 5.3: To make it clear that role communication takes place internally inside the organization, a term was added to clause 5.3 (organizational roles, duties, and authorities).
- Clause 6.2: Item (d), which calls for objectives to be monitored, was added to clause 6.2 (Information security objectives and planning to accomplish them).
- Clause 6.3: Any update to the ISMS must now comply with Clause 6.3 (Planning of Changes), which stipulates that it must be done in a planned way.
- Clause 7.4: Item (e), which called for establishing communication procedures, was removed from clause 7.4 (Communication).
- Clause 8.1: There are new requirements for creating criteria for security procedures and for carrying out activities in accordance with those criteria in paragraph 8.1 (operational planning and control). The necessity to implement strategies for accomplishing objectives was removed from the same clause.
- Clause 9.3: The addition of new item 9.3.2 (c) to clause 9.3 (management review) makes it clear that suggestions from interested parties must address their requirements and expectations and be pertinent to the ISMS.
- Clauses 10.1 and 10.2: The subclauses in clause 10 (Improvement) have been rearranged such that the first one is now Continuous Improvement (10.1), and the second one is now Nonconformity and Corrective Action (10.2), even if the language of those clauses has remained the same.
Summary of Major Changes in ISO 27001:2013 and ISO 27001:2022
The majority of ISO 27001:2022’s changes are quite minimal and may be rapidly implemented with small modifications to documentation and procedures. Enhancing risk assessment and management, offering more customization choices, and stressing supply chain security are the key goals of the modifications.
CHANGES MADE IN ANNEX A SECURITY CONTROLS:
ISO/IEC 27001:2022 brings forth notable revisions to Annex A, resulting in substantial changes to both the quantity and arrangement of security controls. Alongside these updates, the title of the Annex has transitioned from “Reference control objectives and controls” to “Information security controls reference,” reflecting the revised approach.
One of the primary alterations is the reduction in the total count of Annex A controls, from 114 controls in the previous version to 93 controls in ISO/IEC 27001:2022. This reduction is primarily achieved through the consolidation of multiple controls. As a result, 35 controls have remained unchanged, while 23 controls have undergone renaming for improved clarity and alignment with industry terminology.
Significantly, 57 controls have been merged into 24 consolidated controls, aiming to streamline and eliminate redundancies. This consolidation facilitates a more efficient implementation process and improves the overall effectiveness of the controls. Additionally, one control has been split into two separate controls, further refining the granularity and specificity of the control set.
The restructured controls are now organized into four distinct control groups or sections, known as themes. These themes are people, organizational, technological, and control. Each group encompasses controls related to specific aspects of information security, promoting a more organized and coherent control framework.
These revisions in ISO/IEC 27001:2022’s Annex A reflect a concerted effort to enhance the clarity, effectiveness, and adaptability of the standard’s control framework. By aligning with evolving industry practices and requirements, the updated controls provide improved usability and flexibility in implementing robust information security measures. These enhancements empower organizations to better address emerging threats and secure their information assets with greater confidence and efficiency.
New Security Controls:
- Threat intelligence
- Information security for the use of Cloud services
- ICT readiness for business continuity
- Physical security monitoring
- Configuration management
- Information deletion
- Data masking
- Data leakage prevention
- Monitoring activities
- Web filtering
- Secure coding
