What are the internal and external issues in ISO 27001?

When it comes to cyber security, the old saying rings true: control what you can and prepare for what you can’t. This mindset is especially true when working towards ISO 27001 certification. Why? Because the success of your Information Security Management System (ISMS) hinges on recognising and addressing key factors both inside and outside your organisation’s control.

For companies trying to get an ISO 27001 certification, this understanding isn’t just a ‘nice to have’ it’s a requirement outlined in Clause 4.1 of the Standard. This article dives into these critical factors, so you can get a better understanding of how internal and external factors affect the implementation of your ISMS.

Internal issues affecting ISMS outcomes

Internal issues are factors within the direct control of a company. These include:

• Organisational structure: this defines how activities are directed and aligned to achieve the organisation’s long-term goals. Understanding the roles and responsibilities related to ISO 27001 helps position the ISMS effectively.
• Available resources: these are the organisational infrastructure, systems, processes, personnel, technology, equipment, knowledge, and time that guide the development of solutions, competencies, and acquisitions.
• Organisational drivers: factors that help develop support and infrastructures critical for defining an organisation’s information security strategies, objectives, and policies. These often include the organisation’s mission, vision, and values.
• Organisational operations: knowing how the organisation executes operations is vital. Understanding processes, decision-making, and information flow within the organisation helps integrate information security processes and determine the ISMS scope.

External issues affecting ISMS outcomes

External issues are factors outside an organisation’s control that impact its progress or success. While an organisation can’t control these factors, it can however adapt to them. They include:

• Applicable legal and regulatory policies: laws and regulations the organisation must comply with.
• Market and customer trends: constantly changing trends require vigilance. For example, the adoption of cloud services is a trend that should be considered in the ISMS.
• External relationships: the values, beliefs, and perceptions of external interested parties must be considered.
• Technological trends: new technologies can provide new ways to safeguard information or make existing security controls obsolete.
• Political and economic factors: economic and political conditions can significantly impact business operations.

How to document internal and external issues

Under ISO/IEC 27001, you aren’t required to document the context of the organisation in a separate document. However, you must record information on specific issues. For external issues, you should document your information security goals, outcomes of risk assessments, information assets, and the competence of your staff. You must also record the relevant regulatory, contractual, legislative, and statutory requirements.

Why understanding these issues matters

Understanding the internal and external issues that impact your ISMS is not just a requirement of ISO 27001, but a critical step toward ensuring your organisation’s information security objectives are being met. By identifying and documenting these issues, you position your organisation to respond effectively to risks that may arise.
