In this highly competitive marketplace, having ISO compliance establishes a trustworthy reputation and provides you leverage when pitching high-value contracts. It also assists you in meeting established data protection regulations. These further raises consumer confidence in your service business.
These are just a few of the many benefits that ISO compliance offers. Others were introduced with the new ISO 27001:2022 framework. A lot has changed from its first ISO 27001:2013 framework. And in this definitive guide, we will cover what has changed from ISO 27001:2013 to ISO 27001:2022 and how to prepare for the ISO audit
What is ISO 27001 and Information Security Management System?
ISO 27001 is a leading international standard that emphasizes information security. It was put forward by ISO (International Organization for Standardization) in collaboration with IEC (International Organization for Standardization). ISO 27001 outlines the best practices for putting information security controls in place and maintaining them as part of an information security management system (ISMS).
An ISMS is a framework of procedures and policies for systematically protecting the confidentiality, integrity, and availability of an organization. The system is also employed to manage and protect an organization’s sensitive data. An ISMS’s primary objective is to make it easier for businesses to execute the CIA triad of data protection. The CIA trio is made up of:
- Confidentiality: Confidentiality refers to measures a service provider takes to safeguard data. From creation to the collection, the principle guarantees permitted and controlled access to only designated personnel to preserve the privacy of that data.
- Processing Integrity: In order to support data integrity, businesses must work to maintain the validity and dependability of the data and ensure that it is error-free.
- Availability: Businesses are responsible for ensuring that information is available whenever it will be accessed. This also includes redundant server deletion, scheduled upgrading, and efficient data running.
What Are the Benefits of ISMS?
ISMS is a reliable method of protecting information assets. Besides security assurance, there are several benefits that ISMS offers. A few of them are:
- Risk Reduction: It helps businesses reduce risks like data breaches, financial losses, and reputational harm by identifying and addressing possible security concerns before their occurrence. This further helps protect reputation.
- Competitive Edge: By proving their dedication to data security and compliance, businesses can acquire a competitive edge with the help of an ISMS.
- Cost Savings: ISMS assists businesses in making long-term financial savings. It does so by lowering the cost of dealing with data breaches and maintaining compliance with relevant laws and regulations.
- Legal Compliance: Information security is governed by an expanding number of laws, rules, and contractual obligations. By implementing ISO 27001, many of them can be met with ease.
What’s Changed in ISO 27002:2022 from ISO 27002:2013
Simply put, ISO 27002 is more of a best practices guide, offering advice on how to apply and comprehend the ISO 27001 controls in Annexure A, whereas ISO 27001 is a cybersecurity framework and firms may acquire certification. Although ISO 27001:2022 and ISO 27001:2013 are not considerably different, the following modifications stand out:
- Context and Scope: You now must determine which ‘relevant’ requirements of interested parties will be met by the ISMS. ISMS now also includes the phrase ‘processes needed and their interactions’.
- Planning: The objectives of information security must now be tracked and made ‘accessible as recorded information.’ The ISMS now has a new section devoted to planning modifications.
- Support: It is now necessary to specify ‘how to communicate’ instead of ‘who will communicate’ and ‘the mechanisms for accomplishing communication.’
- Operation: Organizations must now manage ‘externally delivered processes, goods, or service’ that are important to the ISMS, not simply processes.
- Performance and Evaluation: Methods of monitoring, measuring, analyzing, and evaluating the effectiveness of the ISMS now need to be comparable and reproducible. The management review must now also consider changes in the needs and expectations of interested parties.
- Annex A: Annex A has undergone revision.
Control Changes in Annex A
Annex A is the most important change in ISO 27002:2022. Categories of controls are reduced to 4 from 14. The most significant changes in controls are:
- People (14 controls)
- Organizational (37 controls)
- Technological (34 controls)
- Physical (14 controls)
The completely new controls that are introduced are:
- Threat Intelligence: You must obtain and evaluate threat information for this control in order to implement the necessary mitigation measures.
- Information Security for Use of Cloud Services: To improve the security of cloud data, this control needs you to define security criteria for cloud services, including purchasing, using, managing, and terminating the use of cloud services.
- IC Readiness for Business Continuity: This control necessitates information and communication technology to be prepared for unexpected interruptions to ensure data and assets’ security and availability. Planning, implementing, testing, and maintenance for preparedness are all included.
- Physical Security Monitoring: The control promotes sensitive places monitoring so that only individuals with permission may enter them. It includes office locations, manufacturing plants, warehouses, and other buildings.
- Configuration Management: This control necessitates the management security configuration cycle for security and unauthorized modification prevention. This involves the definition, implementation, monitoring, and review of the configuration.
- Information Deletion: This control necessitates ineffective data deletion for data breaching prevention. Deletion in your IT systems, portable media, or cloud services is a few examples of this.
- Data Masking: This control mandates the use of access control and data masking to minimize the disclosure of sensitive information. Since they are strictly controlled by privacy laws, this generally refers to personal and sensitive data.
- Data Leakage Prevention: This control entails applying multiple data leakage controls to prevent the unauthorized exposure of sensitive information. If it does, quickly identify such instances. This applies to data on all devices, networks, and IT systems.
- Monitoring Activities: It entails constant system monitoring to spot odd activity. If necessary, initiate the proper incident reaction. IT systems, networks, and apps are all monitored as part of this.
- Web Filtering: It requires you to regulate the user-accessed websites. By doing so, you can stop users from accessing illicit content and stop harmful programs from compromising your systems.
- Secure Coding: This entails defining secure coding standards and using them in your software development to reduce security flaws. It covers everything that happens before, during, and after the coding.
ISO 27001 Certification Process
A business must demonstrate that it has effectively implemented an ISMS and taken the appropriate precautions to mitigate risks in order to get the coveted ISO 27001 certification. Three steps comprise the audit for an ISO 27001 accreditation.
Stage 01: Here, an auditor examines the documented ISMS and determines if it complies with the standards. An essential need for certification is that organizations publish a Statement of Applicability (SoA). It includes listed 114 controls in Annexure A, the steps for implementing each control, and a list of the controls that were left out and their justifications. There is very little engagement with those responsible for monitoring the ISMS’s implementation throughout this activity.
Stage 02:In stage 2, the businesses are audited to see whether the processes it employs are consistent with those described in the ISMS. Along with conducting interviews with persons in charge of operations, the auditors examine all of the documentation supporting materials and the risk management procedures. Typically, three months’ worth of documentation is needed.
Surveillance Audit: An ISO 27001 certification is good for three years after it is obtained, at which point a re-certification evaluation is done. Following certification, businesses should
anticipate surveillance inspections at least once a year to make sure they are developing and implementing the most recent security measures in order to remain cautious and up-to-date.
How to Transition from ISO 27001 Version 2013 to 2022
Businesses will need to examine existing risk assessments to see whether changes or new risk treatments need to be adopted. The new edition of the standard includes the controls described by ISO 27002:2022. The 8 essential actions that an organization with an ISO 27001 certification may follow to effectively migrate to the new standard are outlined below:
01. Understand the Changes
Gain a deeper understanding of ISO 27002:2022 and the new security controls specification.Instead of 114 controls, ISO 27002:2022 now contains 93 controls distributed over 4 types: organizational, people, physical, and technological. Ensure that most controls are open to some kinds of text changes. It will affect the understanding and implementation of the standard.
02. Assess Your Training Requirements
Create a training program for your team members to build their knowledge around the standard and ensure they can implement the changes effectively.
03. Carry Out a Gap Analysis
Gap Analysis will help you find priority areas that need to be addressed before you transition to ISO 27001:2022. It compares your current controls and risk treatments to those in ISO 27002:2022. Annex B is a good place to start. It provides a helpful comparison of all available controls and how they relate to those in the previous edition (ISO 27002:2013). Create a specialized team that can own and offer expertise in organizational, people, physical, and technology categories.
04. Revisit your Risk Assessment
Verify that your risk assessment, together with its goals and context, is in line with your business and risk tolerance. If not, make the adjustments. You can consult the international standard ISO 27005, which describes the steps to take when performing an information security risk assessment.
05. Update Your Risk Treatment Plan (RTP)
Choosing the necessary controls from the new version of ISO 27002, which is included in Annex A of ISO 27001:2022, you must update the RTP to reflect your decisions on threat response. Conduct another gap analysis to make sure the controls you have chosen are sensible and effective.
06. Update Your Statement of Applicability (SoA)
It is critical to update your SoA to provide the supporting data and arguments for including and excluding any restrictions or rules. You must also emphasize if your company has established any RTP-compliant controls. If the answer is yes, a thorough internal audit program should be implemented to evaluate how well your initiatives are working.
07. Book Your Transition Audit
You must reinforce your management system, information security, and overall cyber resilience here. Once you do, the next step is to book a transition audit.
08. Complete Your Audit and Implement Any Changes
With a prime focus on the revisions to the controls in Annex A, your auditor will evaluate your ISMS and accompanying documentation to see if it complies with ISO 27001:2022’s standards. Your Audit Report includes your auditor’s comments and any issues that must be resolved before certification is granted. After the process is complete, the certification will be given to you.
