Auditing ISO 27001 Clause 7.1 (Resources) is a critical phase in achieving and maintaining UKAS-accredited certification. This clause transitions an Information Security Management System (ISMS) from theoretical policy to operational reality. By verifying an organisation’s tangible commitment through people, budget, and infrastructure, an audit confirms that information security is a functional pillar of business operations.

Understanding the Core Requirements of Clause 7.1
Clause 7.1 is a non-negotiable mandatory requirement of the ISO 27001:2022 standard. It mandates that organisations determine and provide the resources necessary for the establishment, implementation, maintenance, and continual improvement of the ISMS.
- Senior Management Accountability: The provision of resources is a direct reflection of leadership commitment (Clause 5.1).
- Comprehensive Planning: Resources are not merely financial; they include human capital, technological tools, and physical infrastructure.
- Resource Versatility: Compliance can be achieved through internal staff, external consultants, or managed service providers (MSPs).
Decoding Clause 7.1: The Foundation of Your Audit
Before interviewing staff or reviewing evidence, you must understand the “What” and the “Why” of the standard. ISO 27001 Clause 7.1 states:
“The organisation shall determine and provide the resources needed for the establishment, implementation, maintenance and continual improvement of the information security management system.”
The Three Pillars of ISMS Resources
- Human Resources: Personnel with the appropriate skills, knowledge, and, crucially, the time to manage the ISMS.
- Financial Resources: Allocated budgets for security tooling, software, external audits, and professional training.
- Infrastructure: IT systems, cloud environments, and physical facilities required to meet security objectives.
Note for SMEs: In smaller organisations, one individual often wears multiple hats. While acceptable, this must be balanced with the Segregation of Duties. For example, the person requesting system access should not be the same person approving it, as per Annex A controls.
The Auditor’s Perspective: What Scrutiny Looks Like
Adopting an auditor’s mindset allows you to proactively close compliance gaps. For Clause 7.1, an auditor seeks proof of genuine, sustained support rather than a “paper-only” exercise.
Primary Areas of Auditor Focus
- ISO 27001 Subject Matter Expertise: Auditors verify if the ISMS is guided by competence or guesswork. Lack of specialist knowledge is a leading cause of Major Non-Conformities.
- The Competency Matrix: This is often the first document requested. It maps roles to specific skills and identifies training gaps.
- Annex A Resource Allocation: Auditors check if the resources mentioned in the Statement of Applicability (SoA) actually exist in practice.
ISMS Lifecycle Resource Strategy
| Phase | Resource Strategy |
|---|---|
| Establishment | Utilise external specialists to build a compliant framework quickly. |
| Implementation | Leverage consultants to mentor internal teams and accelerate control deployment. |
| Certification | A collaborative effort between specialists (for technical defence) and internal staff (for operational evidence). |
| Maintenance | Transition to internal staff for daily operations, using specialists for periodic “sense-checks.” |
| Continual Improvement | Internal staff drive change, while external auditors/consultants provide independent validation. |
The 10-Step Audit Checklist for Clause 7.1
Use this actionable checklist to conduct your internal audit and prepare for external certification.
- Resource Identification: Has the organisation formally documented what it needs (people, tech, budget)?
- Personnel Competence: Are job descriptions and training records aligned with ISMS responsibilities?
- Infrastructure Sufficiency: Is the hardware/software adequate to protect the organisation’s assets?
- Financial Allocation: Is there a clear, approved budget for information security?
- Top Management Support: Do board minutes reflect discussions and approvals of resource requests?
- Resource Maintenance: Are tools kept up-to-date through patch management and hardware refresh cycles?
- Outsourced Competence: Do third-party contracts and SLAs guarantee the necessary security expertise?
- Documentation of Allocation: Are there clear records showing who is responsible for what (e.g., an Accountability Matrix)?
- Regular Resource Reviews: Are resource needs revisited during Management Reviews?
- Utilisation Efficiency: Is the organisation seeking to optimise its security spend and staff time?
Essential Audit Documentation and Evidence
To ensure a smooth audit, prepare a dedicated evidence folder for Clause 7.1 containing:
- Resource Plans & Budgets: Formal proof of financial commitment.
- Organisational Charts: Visual representation of the ISMS structure.
- Accountability Matrix (RACI): Mapping of roles to specific ISO 27001 clauses and Annex A controls.
- Competency Matrix & Training Records: Proof that your team has the skills required to protect your data.
- Management Review Minutes: Evidence that leadership approves resource distribution.
FAQ: Auditing Clause 7.1
What is the primary goal of Clause 7.1?
The goal is to ensure the ISMS has the practical support (people, money, tools) required to succeed. It prevents security from becoming a neglected, underfunded project.
Can one person manage the ISMS in a small company?
Yes, provided they have the competence and time. You must document how you manage the risk of “single point of failure” and maintain Segregation of Duties.
Are external consultants considered a “resource” under Clause 7.1?
Absolutely. Many organisations use consultants for specialised tasks like internal auditing or technical vulnerability management to meet the requirements of the standard.
What is a common mistake in this area?
Underestimating the “time” resource. Staff are often given ISMS responsibilities without being relieved of their daily operational tasks, leading to a failure in system maintenance.
