Modern organizations face the growing challenge of ensuring the security of their information assets in the face of increasingly sophisticated cyber threats. Traditional security models based on trusting internal users and devices are becoming inadequate in a dynamically changing IT environment. In response to these challenges, more and more companies are implementing the Zero Trust security model, which assumes the principle: “never trust, always verify”.
A central element of Zero Trust architecture is identity and access management (IAM), which enables precise control of who, when, and how has access to organizational resources. Under this approach, every access attempt is treated as a potential threat and requires multi-step verification, regardless of the user’s location or device.
In this article, we will examine how effective identity and access management forms the foundation of a Zero Trust strategy, and discuss key principles and technologies supporting this approach.
ISO 27001 Internal Audit – Unpleasant Obligation or Invaluable Opportunity for Growth? Let’s Change Our Perspective!
For many people in an organization, the word “audit” itself is associated with something unpleasant—control, pointing out errors, extra work, and stress. An internal audit of an Information Security Management System (ISMS) compliant with ISO 27001 is often no exception and is frequently perceived as another formal requirement to be “checked off” before certification or surveillance audits. It’s a bit like visiting a strict teacher just to get a grade, not to learn something. But does it really have to be this way? What if I told you that an internal audit, if properly conducted and correctly understood, can become your personal security trainer—a demanding but fair mentor who will help you identify weaknesses, strengthen muscles, and achieve championship form in information protection? Time to change perspective!
The truth is that ISO 27001 internal audits, although formally required by the standard (Clause 9.2), were not invented to make employees’ lives difficult or generate unnecessary bureaucracy. Their primary purpose is to provide the organization with objective feedback on whether its ISMS is effectively implemented, maintained, and compliant with both the standard’s requirements and internal policies and business objectives. It’s like a regular vehicle inspection—you don’t do it so the inspector finds faults (though that’s important too), but to be sure your vehicle is functional, safe, and ready for the road ahead.
If we treat internal audits not as witch hunts but as constructive diagnostic tools and mechanisms for continuous improvement (in the spirit of the PDCA cycle—Plan-Do-Check-Act), entirely new possibilities open up before us. Instead of stress and defensiveness, there’s an opportunity for:
-
Early detection of nonconformities and weaknesses before they become serious problems or are identified by external auditors (which could have consequences for certification).
-
Identification of areas where the ISMS isn’t working as effectively as it should and pointing out specific opportunities for improvement.
-
Verification that implemented safeguards (controls) are adequate to actual risks and are actually applied in practice by employees.
-
Raising information security awareness across the organization through engagement of various departments in the audit process and discussion of its results.
-
Gathering valuable input data for ISMS management review (required by Clause 9.3 of the standard), which is a key moment for making strategic security decisions.
-
Building a culture of openness and continuous learning, where mistakes are treated as opportunities for improvement, not reasons for shame.
The key to such a change in perspective is the appropriate attitude from both internal auditors (who should serve as partners and advisors, not just controllers) and from audited persons and departments (who should see the audit as an opportunity for growth). When internal audits cease to be perceived as unpleasant obligations and become an integral part of striving for operational and security excellence, their value to the organization grows immensely.

How to Plan and Conduct an Internal Audit Well So It’s Not Just a Formality But a Real Test of Your ISMS?
For an ISO 27001 internal audit to bring real value and not become just a bureaucratic formality, it requires careful planning, professional execution, and objective assessment. This is not an activity that can be done “quickly” or “superficially.” It’s like preparing and conducting an important scientific experiment—every step must be thought through, and results must be reliable.
Step 1: Establishing an Audit Program – Your Control Roadmap. ISO 27001 requires establishing an internal audit program that defines, among other things, frequency, methods, responsibilities, planning requirements, and reporting. This is your roadmap.
-
Frequency: Audits should be conducted at planned intervals (e.g., once a year for the entire ISMS, or more frequently for higher-risk areas or after significant changes).
-
Scope: Each audit should have a clearly defined scope—which processes, departments, locations, or standard clauses will be evaluated.
-
Audit criteria: What will you evaluate against? Criteria typically include ISO 27001 requirements, your internal ISMS documentation (policies, procedures), and applicable legal and contractual requirements.
-
Auditor selection: Ensuring auditor objectivity and impartiality is key. They should not audit their own work. Auditors must have appropriate competencies (knowledge of ISO 27001, auditing techniques, and your organization’s specifics).
Step 2: Careful Planning of Each Audit – The Devil Is in the Details. Once you have a program, each individual audit requires an individual plan.
- Audit objectives: What specifically do you want to achieve with this audit?
- Detailed scope and criteria (as above, but refined for the given audit).
- Schedule of audit activities: When will opening meetings take place, when will interviews be conducted, documentation review, observations, and when will the closing meeting be held?
- Audit team: Who will conduct the audit? What are their roles?
- Communication with auditees: How and when will you inform audited persons and departments about the planned audit, its objectives, and scope?
Step 3: Professional Conduct of Audit Activities – The Art of Evidence Collection. This is the heart of the audit. Auditors collect evidence (objective information) of conformity (or nonconformity) with audit criteria.
Step 4: Reliable Analysis of Results and Formulating Findings – No Emotions, Just Facts. After collecting evidence, auditors must carefully analyze and evaluate it against audit criteria. The results of this analysis are audit findings, which can be:
- Conformities: Confirmation that everything is working as it should.
- Nonconformities: Determination that a requirement (of the standard, policy) is not met.
- Observations or Opportunities for Improvement (OFI): Suggestions for areas that, while currently compliant, could work better or more efficiently.
Step 5: Preparing the Audit Report and Closing Meeting – Passing the Baton. Audit results are documented in a report that should be complete, precise, concise, and understandable.
What Are the Most Common Errors and Deficiencies Detected During Internal Audits?
Internal ISO 27001 audits, if conducted reliably and thoroughly, often reveal certain typical errors and deficiencies in the Information Security Management System (ISMS). This is natural, especially in the first years of system operation or in organizations that are dynamically changing.
Common problems that come to light during internal audits include:
- Insufficient or outdated ISMS documentation
- Lack of evidence of implementation and compliance with defined controls and procedures
- Insufficient employee awareness and competencies in information security
- Problems with information security risk management
- Deficiencies in information security incident management
- Lack of evidence of continuous ISMS improvement
How to Effectively Manage Audit Results and Implement Corrective Actions?
An ISO 27001 internal audit report, with its list of conformities, nonconformities, and opportunities for improvement, is not a document that should end up on a shelf gathering dust. It’s a treasure map that, if properly read and used, can take your organization to a significantly higher level of information security.
Step 1: Formal acceptance and communication of audit results. Step 2: Root cause analysis of nonconformities. Step 3: Planning and implementing corrective actions. Step 4: Verification of the effectiveness of implemented corrective actions. Step 5: Utilization of “opportunities for improvement” (OFI). Step 6: Inclusion of audit results in management review. Step 7: Promoting a culture of continuous improvement.
