Before we get started, brush up on your need-to-know ISO 27001 compliance terms and definitions.

Step 1: Develop an Implementation Team and Plan

The first step is creating a dedicated team responsible for developing and implementing your information security management system (ISMS) as per ISO 27001 requirements. This cross-functional team should include representatives from across your organization, such as a project manager, information security personnel, technical experts, and leadership.

Action Items:

  • Assemble the implementation team with the right skills and experience.
  • Define clear roles, responsibilities, and authorities for team members.
  • Develop a comprehensive project plan with milestones and deadlines.

Step 2: Understand ISO 27001 Requirements

Before you can build an ISMS, you should to thoroughly understand what ISO 27001 entails. This crucial standard provides a framework of policies and procedures covering all aspects of infosec risk management.

Action Items:

Step 3: Find Your Security Baseline

Action Items:

  • Identify existing security processes that meet ISO 27001 compliance requirements.
  • Note any deficiencies or gaps creating unaddressed risks.
  • Determine areas requiring more risk analysis or clarity.

Step 4: Define the ISMS Scope

Clearly define what parts of your business the ISMS will cover in terms of locations, assets, technologies, and processes – this is the ISMS scope. Then conduct a risk assessment and document which ISO 27001 controls apply in a Statement of Applicability.

Action Items:

  • Determine the scope of your ISMS.
  • Perform an infosec risk assessment.
  • Create a Statement of Applicability mapping required controls.

Step 5: Create and Implement an ISMS Plan

Develop a comprehensive set of policies, processes, and procedures to implement the ISMS systematically across your defined scope. These should cover all applicable ISO 27001 controls.

Action Items:

  • Document an ISMS policy defining principles and responsibilities.
  • Implement robust processes for access control, incident response, etc.
  • Define metrics to measure the effectiveness of security controls.

Step 6: Train Employees on Policies and Procedures

A key aspect of ISO 27001 is embedding security awareness and compliance across the workforce through training and clear disciplinary policies.

Action Items:

  • Train all staff on new ISMS policies and procedures.
  • Ensure incident response teams are trained on response plans.
  • Define and communicate sanctions for security violations.

Step 7: Conduct an Internal Audit

Before the certification audit, you should conduct rigorous internal audits using experienced auditors independent from the ISMS implementation. This proactive step identifies any gaps.

Action Items:

  • Engage unbiased internal or external auditors
  • Auditors review documentation, test controls, and uncover nonconformities.
  • Produce an internal audit report with required corrective actions.
  • Implement all listed corrective actions before the certification audit.

Step 8: Find an Accredited Auditor to Lead the ISO 27001 Compliance Audit

The culmination is a two-stage certification audit performed by an accredited external auditor who will scrutinize every aspect of your ISMS against ISO 27001 requirements.

Action Items:

  • Select a reputable ISO 27001 compliance auditor
  • Host the Stage 1 readiness review audit
  • Implement any required remediation from Stage 1
  • Complete the Stage 2 certification audit
  • Address any further nonconformities identified
  • Maintain your ISMS and undergo annual surveillance audits
