ISO 27001:2022 — Building an Information Security Management System That Auditors Trust

ISO 27001:2022 is the international standard for information security management systems. Achieving certification demonstrates to clients, partners, and regulators that your organization manages information security risks systematically.

What the standard actually requires

ISO 27001 requires organizations to establish, implement, maintain, and continually improve an ISMS. The core is a risk assessment process that identifies information assets, evaluates threats and vulnerabilities, and selects controls proportionate to the risk.

The Annex A controls

The 2022 revision reorganized the controls into four themes: organizational, people, physical, and technological. Organizations must evaluate which controls are applicable and document their reasoning in a Statement of Applicability.

• Asset inventory and classification
• Access control and identity management
• Incident management and response procedures
• Supplier security assessment process
• Business continuity and recovery planning

Common gaps in first-time implementations

Most organizations underestimate the documentation requirements for risk treatment plans and the evidence needed to demonstrate that controls are operating effectively. Internal audit programmes also frequently lack the depth auditors expect.

The certification audit process

Stage one reviews documentation and readiness. Stage two tests whether the ISMS is implemented and operating as documented. Surveillance audits follow annually, with recertification every three years.

How DCG supports ISO 27001 programmes

DCG manages the full implementation cycle from asset inventory and risk assessment through documentation, internal audit, and certification support. We also help organizations integrate ISO 27001 with existing ISO 9001 or ISO 45001 systems to reduce duplication.
