How to Prepare for ISO 27001:2022 Certification: A Complete Guide for Businesses

Data leaks, ransomware risks, and client security requirements are becoming harder for Malaysian businesses to ignore. Many companies now need stronger proof that their information, systems, and customer data are properly protected.

ISO 27001:2022 helps businesses build that proof through a structured Information Security Management System (ISMS). It also supports stronger client trust, smoother vendor approval, and better readiness for audits.

Your team needs to understand the requirements, close security gaps, manage risks, and prepare for the certification audit. 

The sections below break down the key steps to prepare for ISO 27001:2022 certification and show how One Island’s training can help your business move forward with confidence.

What Is ISO 27001:2022 and Why Does It Matter for Malaysian Companies?

ISO 27001:2022 helps businesses prove that their information security practices are properly managed, documented, and ready for audit. It gives clients, partners, and stakeholders greater confidence that sensitive business data is protected.

Many Malaysian companies pursue ISO 27001:2022 certification because it supports:

Business Need	Why ISO 27001:2022 Helps
Vendor approval	Strengthens credibility for tenders, GLCs, MNCs, and enterprise clients
Client trust	Shows that data security is managed through a recognised system
Risk control	Helps reduce gaps in access control, data handling, and internal processes
Audit readiness	Prepares teams with proper policies, records, and risk management practices

In sectors such as finance and healthcare, it also supports alignment with Bank Negara Malaysia’s Risk Management in Technology (RMiT) framework and the Personal Data Protection Act (PDPA). 

Being certified signals to clients, partners, and regulators that your organisation manages information security with discipline and accountability.

7 Steps to Prepare for ISO 27001:2022 Certification

Preparation is where most organisations either build a solid foundation or set themselves up for audit failure. Here is the sequence that works.

Step 1: Conduct a Gap Analysis

A gap analysis compares your current information security practices against the requirements of ISO 27001:2022. It identifies which controls are already in place, which are partially implemented, and which are missing entirely. This is the starting point for your project plan and helps you estimate the scope of work ahead.

One Island Consultancy conducts gap analyses that map your existing policies and technical controls against the ISO 27001:2022 clause requirements, giving you a clear view of where to prioritise your efforts.

Step 2: Define the Scope of Your ISMS

Scope definition determines which parts of your organisation, which assets, and which processes will fall under the ISMS. A well-defined scope keeps your certification manageable. A poorly defined scope either leaves critical assets unprotected or creates unnecessary audit burden.

Your scope statement should specify the organisational units included, the physical locations, the information assets covered, and any interfaces with external parties. Auditors will scrutinise this document closely. 

Step 3: Perform a Risk Assessment

ISO 27001:2022 is fundamentally risk-based. Your risk assessment must identify information assets, the threats and vulnerabilities that apply to each, and the potential impact if those risks materialise. The methodology you use must be documented and repeatable.

Common frameworks used in Malaysia include NIST SP 800-30 and the ISO 27005 risk management guideline. The output of this step is a risk register that feeds directly into your risk treatment plan.

Step 4: Develop and Implement Your Risk Treatment Plan

Once risks are identified and evaluated, you need to select controls to treat them. ISO 27001:2022 provides 93 controls across four themes: Organisational, People, Physical, and Technological. 

You are not required to implement every control, but you must justify any that you exclude in your Statement of Applicability (SoA).

Implementation means more than documenting policies. Controls need to be operationalised: staff need to be trained, technical configurations need to be in place, and processes need to be followed consistently.

Step 5: Conduct an Internal Audit

This is a formal review of whether your ISMS is operating as documented and whether it meets the requirements of the standard. Internal auditors must be independent from the areas they are auditing.

Many organisations engage a third-party consultant to conduct internal audits, which provides greater objectivity and often surfaces issues that internal teams miss.

Step 6: Management Review

Senior leadership must formally review the performance of the ISMS before the certification audit. This review looks at audit results, security incidents, the status of corrective actions, and any changes in the risk environment. 

Minutes from this meeting form part of your audit evidence.

Step 7: Certification Audit

The certification audit is conducted by an accredited third-party certification body and takes place in two stages. 

Stage 1 is a document review, where the auditor assesses whether your ISMS documentation is complete and appropriate. Stage 2 is an on-site audit, where the auditor verifies that your controls are actually implemented and effective.

If nonconformities are found, you will need to address them before certification is granted. Minor nonconformities typically require a corrective action plan. Major nonconformities may require a follow-up visit.

4 Common Mistakes That Delay ISO 27001:2022 Certification

ISO 27001:2022 certification can slow down when teams focus too much on paperwork and overlook the controls, people, and audit evidence behind the system. 

1. Treating it as a documentation project

ISO 27001:2022 requires evidence that controls are operational, not just written down. Auditors will interview staff, review logs, and test processes.

2. Underestimating the scope

Organisations sometimes exclude systems or departments from the ISMS scope to simplify the project, then discover during the audit that those exclusions create unacceptable risk gaps.

3. Skipping the internal audit

Some organisations move directly to the certification audit without completing a proper internal audit. This almost always results in nonconformities that delay certification.

4. Insufficient management commitment

ISO 27001:2022 requires visible leadership involvement. If senior management is not engaged, security resources stay underfunded and the ISMS becomes a compliance checkbox rather than a functioning system.

One Island’s ISO 27001:2022 training helps your team avoid these mistakes by building audit readiness through proper scoping, documentation, internal audits, and leadership alignment.

Case Study: 50% Lower Cybersecurity Risk for a Malaysian Tech Firm

A Malaysian tech firm handling sensitive client data needed stronger information security controls to reduce cyber risk and meet growing client expectations.

The company handled sensitive client data, but its controls were not consistently documented, monitored, or communicated across teams.

• Risk assessment was not structured enough to identify high impact threats
• Access control practices differed across departments and systems
• Security policies existed, but staff were unclear about daily responsibilities
• Incident response steps were not fully tested or understood
• Internal audit preparation was limited, which increased the risk of nonconformities during certification

One Island Consultancy supported the company through ISO 27001 implementation, covering ISMS setup, risk assessment, employee training, security control alignment, audit preparation, and crisis response planning.

• One Island guided the team through ISMS scope setting and risk assessment
• Key security controls were reviewed against ISO 27001 requirements
• Policies and procedures were updated to support daily implementation
• Staff training helped employees understand data handling, access control, and incident reporting
• Internal audit preparation helped the company identify gaps before the certification audit
• Corrective actions were planned to close weaknesses before external assessment

The result was a 50% reduction in cybersecurity risks, stronger protection for sensitive client data, and improved confidence during client security evaluations.

• Cybersecurity risks reduced by 50%
• Sensitive client data became better protected
• Audit readiness improved across key departments
• Client confidence increased during security evaluations
• The company became better prepared for ISO 27001 certification
