Implementing ISO 27001 is a coherent improvement cycle. Risks, measures, roles, registrations and management decisions affect each other. The roadmap helps an organisation to choose the right order, while the parts are increasingly aligned along the way.
Steps 1 and 2: Target, Scope and GAP Analysis
Determine why the organisation uses ISO 27001: customer demand, procurement, certification, professionalisation or connection to other laws and regulations. Then identify the components, services, locations, systems and suppliers within the scope. An over-stretched scope makes the journey unnecessarily difficult; an artificially narrow scope may leave out the relevant risks.
Then perform an ISO 27001 GAP analysis. This will show which requirements and measures are already demonstrated, which parts exist and where the greatest risks or dependencies lie. The outcome is a feasible roadmap with a clear order.
Use the standard as a management system: Each step is demonstrably contributing to risk management, ownership, execution and improvement.
Steps 3 and 4: Set up governance and risk analysis
Set up roles, consultations, decision-making and reporting. Executive Board sets frameworks and accepts residual risks; risk and process owners follow measures; advise and review experts. Also make it clear how privacy, quality, IT, supplier management and continuity connect to ISMS.
Then assess risks to confidentiality, integrity and availability of information. Connect scenarios to critical processes, systems, people and suppliers. Choose a treatment strategy and appoint an owner per risk. Risk treatment determines what measures are needed and why.
Steps 5 and 6: introduce measures and demonstrate their effectiveness
Work out necessary measures in policies, procedures and technical or organisational arrangements. The Applicability Declaration identifies the management measures that are relevant, how they have been implemented and why any measures are not applicable.
Then let the ISMS really run. Collect evidence of access checks, backup and restore tests, supplier reviews, awareness, incident monitoring, controls and management decisions. Evidence does not have to be extensive, as long as it is current, traceable and connected to an owner and evaluation moment.
- link any major risk to treatment, measure, owner and evidence
- use existing processes and registrations where they can demonstrably work
- Make anomalies visible and follow corrective actions demonstrably
- send to a limited number of useful indicators instead of reporting volume
Steps 7 and 8: Internal audit, management review and improvement
The internal audit shall assess independently whether the ISMS complies with its own commitments and standards, and whether measures are effective in practice. The Management Review shall use audit results, performance, incidents, risks and changes to decide priorities and resources.
Resolve anomalies and assess whether causes have been removed structurally. When certification is the objective, the organisation then chooses an independent certification institution. Kynexis Information Security can build and prepare ISMS; the certification body shall carry out its own audit and decide on the certificate.
