Today’s organizations are facing the growing challenge of ensuring the security of their information assets in the face of increasingly sophisticated cyber threats. Traditional security models, based on trust in internal users and devices, are becoming insufficient in a rapidly changing IT environment. In response to these challenges, more and more companies are implementing the Zero Trust security model, which embraces the principle of “never trust, always verify.”
Central to Zero Trust’s architecture is identity and access management (IAM), which enables precise control over who, when and how an organization’s resources are accessed. Under this approach, every access attempt is treated as a potential threat and requires multi-step verification, regardless of the location of the user or device.
In this article, we will look at how effective identity and access management is the foundation of a Zero Trust strategy, and discuss the key principles and technologies that support this approach.

ISO 27001 internal audit - an unpleasant duty or an invaluable development opportunity? Let’s change the perspective!
For many in an organization, the very word “audit” connotes something unpleasant - an inspection, pointing out mistakes, extra work and stress. An internal audit of an ISO 27001-compliant Information Security Management System (ISMS) is often no exception, and is sometimes seen as just another formal requirement to be “ticked off” before a certification or surveillance audit. It’s a bit like visiting a strict teacher just to get a grade, rather than to learn something. But surely it has to be that way? What if I told you that an internal audit, if properly conducted and properly understood, can become your personal security coach - a demanding but fair mentor to help you identify weaknesses, strengthen your muscles and achieve information security mastery? It’s time to change your perspective!
The truth is that ISO 27001 internal audit, although formally required by the standard (Clause 9.2), was not invented to make life difficult for employees or generate unnecessary bureaucracy. Its primary purpose is to provide an organization with objective feedback on whether its ISMS is effectively implemented, maintained and whether it complies with both the requirements of the standard itself and with internal policies and business objectives. It’s like a regular technical inspection of your car - you don’t do it to have a diagnostician find defects (although that’s important too), but to make sure your vehicle is in good working order, safe and ready to go.
If we treat internal audit not as a witch-hunt, but as a constructive diagnostic tool and a mechanism for continuous improvement (in the spirit of the PDCA cycle - Plan-Do-Check-Act), entirely new opportunities open up. Instead of stress and defensiveness, an opportunity presents itself:
-
Early detection of nonconformities and weaknesses before they become a serious problem or are identified by an external auditor (which can have consequences for the certificate).
-
Identify areas where the ISMS is not working as effectively as it should, and identify specific opportunities for improvement.
-
Verification that the safeguards (controls) implemented are adequate to the actual risks and are actually put into practice by employees.
-
Raise information security awareness throughout the organization by involving various departments in the audit process and discussing the results.
-
Gather valuable input for the SMS management review (required by Clause 9.3 of the standard), which is a key moment for strategic security decisions.
-
Building a culture of openness and continuous learning, in which mistakes are treated as an opportunity to improve, not a reason to be ashamed.
The key to such a change in perspective is the right attitude on the part of both internal auditors (who should act as partners and advisors, not just controllers) and auditees and departments (who should see auditing as an opportunity for growth). When internal audit ceases to be seen as an unpleasant chore and becomes an integral part of the pursuit of operational excellence and safety, its value to the organization increases immeasurably. It is no longer a visit to a harsh teacher, but a session with an experienced coach who will help you achieve your best results.

How to plan and execute an internal audit well, so that it is not just a formality, but a real test of your ISMS?
For an ISO 27001 internal audit to bring real value and not become a mere bureaucratic formality, it requires careful planning, professional execution and objective evaluation. This is not an activity that can be done “on the fly” or “in a huff.” It’s like preparing and conducting an important scientific experiment - every step must be well thought out and the results reliable. So how do you approach this task so that your internal audit becomes a true test of the strength of your Information Security Management System?
Step 1: Establish an Audit Program - Roadmap of Your Audits. ISO 27001 requires the establishment of an internal audit program that specifies frequency, methods, responsibilities, planning and reporting requirements, among other things. This is your roadmap.
-
Frequency: Audits should be conducted at scheduled 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 clauses of the standard will be assessed. You don’t have to audit everything at once; you can divide the ISMS into smaller, manageable parts and audit them periodically.
-
Audit criteria: what will you evaluate against? The criteria are usually the requirements of ISO 27001, your internal ISMS documentation (policies, procedures), as well as applicable legal and contractual requirements.
-
Selection of auditors: It is crucial to ensure the objectivity and impartiality of auditors. They should not audit their own work. Auditors must be competent (knowledgeable about ISO 27001, auditing techniques, and the specifics of your organization). You can use trained internal employees (from other departments) or enlist the support of external experts.
Step 2: Careful Planning of Each Audit - The Devil is in the Details. Once you have a program, every single audit requires a customized plan.
-
Audit objectives: what specifically do you want to achieve with this audit? (e.g., assessing the compliance of process X with procedure Y, verifying the effectiveness of safeguard Z).
-
Detailed scope and criteria (as above, but detailed for a particular audit).
-
Schedule of audit activities: When will the opening meetings be held, when will interviews, documentation review, observations be conducted, 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 auditees and departments about the planned audit, its objectives and scope? This builds trust and facilitates cooperation.
Step 3: Professional Conduct of Audit Activities - The Art of Gathering Evidence. This is the heart of auditing. Auditors collect evidence (objective information) of compliance (or non-compliance) with audit criteria. Methods of collecting evidence include:
-
Review of documentation and records: Analysis of policies, procedures, manuals, reports, logs, results of previous audits, etc.
-
Staff interviews: Interviews with employees at various levels to understand how processes work in practice and whether safety rules are being followed.
-
Observation of activities and conditions: Direct observation of how activities are performed, how rooms are secured, how employees use systems.
-
Testing (sampling): Verifying on selected samples that certain controls are working properly (e.g., checking the configuration of several servers, verifying the permissions of several users). It is important for auditors to remain objective, be inquisitive, but also tactful and build a partnership atmosphere.
Step 4: Reliable Analysis of Results and Formulation of Findings - No Emotions, Just Facts. Once the evidence is collected, auditors must carefully analyze and evaluate it against the audit criteria. The result of this analysis is the audit findings, which can be:
-
Compliance: Confirmation that everything is working as it should.
-
Nonconformities (Nonconformities): A finding that a requirement (standard, policy) is not met. Nonconformities are often divided into major and minor, depending on their impact on the SMS.
-
Observations or Opportunities for Improvement (OFI): Suggestions for areas that, while currently compliant, could work better or more efficiently. It is important that all findings are based on objective evidence and clearly articulated.
Step 5: Prepare the Audit Report and Closing Meeting - Handing over the Baton. The audit results are documented in a report, which should be complete, precise, concise and understandable. The report is then presented and discussed with management and representatives of the audited areas during a closing meeting. This is the moment to clarify doubts and agree on next steps.
Remember, the purpose of an internal audit is not to find errors per se, but to provide valuable feedback that will serve to strengthen your ISMS. A well-planned and professionally conducted audit is an investment that pays for itself many times over in the form of a realistically safer and more resilient organization.
What are the most common errors and shortcomings detected during internal audits and how to turn them into constructive actions?
ISO 27001 internal audits, when conducted reliably and thoroughly, often reveal some common errors and deficiencies in the Information Security Management System (ISMS). This is natural, especially in the first years of the system or in organizations that are dynamically changing. It is important not to treat these discoveries as failures, but as valuable clues - alarm signals that show where to focus efforts and what can be improved. Turning these sometimes painful findings into constructive action is the key to continuous improvement and building true resilience.
What problems most often come to light during internal audits?
- Inadequate or outdated documentation of the ISMS:
The Problem: Policies and procedures are incomplete, do not reflect the organization’s actual processes, are unclear to employees, or simply have not been updated in ages, despite changes in technology, company structure or the legal environment. The Statement of Application (SoA) may be inaccurate or unsubstantiated.
- How to turn it into action? Take this as a signal to thoroughly review and update all documentation. Involve process owners in creating and revising procedures. Simplify the language to make it understandable to everyone. Implement a system of regular documentation reviews.
- No evidence of implementation and adherence to defined controls and procedures:
Problem: Policies exist on paper, but in practice no one applies them, or there are no records (logs, reports, forms) to confirm their implementation. E.g., an access management procedure exists, but there is no evidence of regular reviews of permissions.
- How to turn it into action? Identify the causes - is it lack of awareness, inadequate tools, overly complicated procedures, or perhaps lack of accountability? Implement corrective actions: training, simplification of processes, automation (where possible), clear assignment of responsibility and monitoring mechanisms.
- Insufficient employee awareness and competence in information security:
The problem: Employees are unfamiliar with key security policies, can’t recognize phishing attempts, use weak passwords, and don’t know how to report incidents. This is often due to a lack of regular, engaging training.
- How to turn it into action? Design and implement a comprehensive security awareness program, including regular training (tailored to different employee groups), awareness campaigns, and attack simulations. Measure the effectiveness of these activities.
- Risk management issues in information security:
Problem: The risk assessment process is conducted irregularly, does not cover all key assets and risks, the methodology is unclear, and risk handling plans are not consistently implemented or monitored.
- How to turn it into action? Streamline the risk management process. Ensure it is integrated with business objectives. Regularly update the risk assessment in response to changes. Implement a system to monitor progress on risk handling plans.
- Shortcomings in the area of information security incident management:
Problem: Lack of clear procedures for reporting and handling incidents, delays in response, insufficient root cause analysis, lack of lessons learned and corrective actions after incidents.
- How to turn it into action? Review and improve your incident response plan. Conduct regular tests and simulations. Ensure that employees know how and where to report incidents. Implement systematic “lessons learned” analysis.
- No evidence of continuous improvement of the SMS:
Problem: The system has been implemented, certification obtained, but nothing has changed since then. There is a lack of corrective actions taken in response to nonconformities, the results of audits or management reviews do not translate into real improvements.
- How to turn it into action? Strengthen the role of management review as an engine for improvement. Implement a systematic process for managing corrective and preventive actions. Promote a culture of continuous learning and improvement-seeking.
Remember, the purpose of an internal audit is not to find fault, but to identify weaknesses in the system so that they can be strengthened. Every non-compliance or observation detected is valuable feedback that, if handled properly, will contribute to making your ISMS not only “compliant on paper,” but more importantly, realistically effective in protecting your organization.
How to effectively manage audit results, implement corrective actions and use them for continuous improvement?
An ISO 27001 internal audit report, with its list of compliance, non-compliance and opportunities for improvement, is not a document that should go on the shelf and get covered in dust. It’s a treasure map that, if read and used properly, can take your organization to a much higher level of information security. Effectively managing audit results, systematically implementing corrective actions and strategically using these lessons learned to continuously improve your Information Security Management System (ISMS) is a process that requires commitment, discipline and the right mechanisms.
Step 1: Formal acceptance and communication of audit results. Upon receipt of the report, management and those responsible for the audited areas should formally review its contents. It is important that the results are communicated in a clear, constructive and non-judgmental manner. The goal is to understand the problems and jointly seek solutions, not to find fault. The audit closing meeting is an excellent opportunity to discuss the findings and clarify any doubts.
Step 2: Analyze the root causes of noncompliance. For every identified nonconformity (especially the more serious ones - large or recurring small ones), it is crucial to conduct an in-depth root cause analysis. It is not enough to “fix” the symptom of the problem. You need to understand why it occurred in the first place - is it an error in procedure, lack of employee awareness, an inadequate tool, or perhaps a systemic problem? Techniques such as the “5 Why” or the Ishikawa (fishbone) diagram can be very helpful here. Without understanding the root causes, there is a high risk that the problem will recur in the future.
Step 3: Plan and implement corrective actions. Based on the root cause analysis, appropriate corrective actions should be planned and implemented for each nonconformity to remove the cause of the problem and prevent its recurrence. The corrective action plan should specify:
-
What exactly is to be done?
-
Who is responsible for carrying out the activity?
-
What is the completion date?
-
What resources are needed?
-
How will the effectiveness of the measure be verified? It is important that the actions are realistic, measurable and implementable. Progress in implementing corrective actions should be monitored regularly.
Step 4: Verify the effectiveness of the implemented corrective actions. Once corrective actions have been implemented, it is necessary to verify that they have had the desired effect and that the nonconformity has indeed been corrected. This may require conducting an additional targeted mini-audit, indicator analysis or observation. If the action proved ineffective, it is necessary to return to the root cause analysis and plan the next steps.
Step 5: Take advantage of “opportunities for improvement” (OFI). In addition to non-compliance, internal audit also often identifies “opportunities for improvement” - areas that, while formally compliant, could work better, more efficiently or be more resilient. These should not be ignored! These are valuable clues to proactively improve the ISMS before real problems arise. Consider implementing these suggestions as part of your system improvement plans.
Step 6: Incorporate audit results into management review. The results of internal audits, along with progress in implementing corrective actions and analyzing trends, are the key inputs to regular management reviews of the SMS (required by Clause 9.3 of ISO 27001). It is during the management review that top management assesses the overall effectiveness of the SMS, makes strategic decisions on its improvement and allocates necessary resources.
Step 7: Promote a culture of continuous improvement. The most important thing, however, is that the whole process should not be a mere formality, but become an integral part of the organizational culture. The idea is that every employee should feel responsible for identifying and reporting potential problems and looking for ways to improve information security. Openness to criticism, a willingness to learn from mistakes, and a relentless pursuit of excellence - these are the hallmarks of an organization that truly takes its security seriously.
Effective audit performance management is not a sprint, but a marathon. It’s a continuous cycle of planning, acting, checking and correcting that, if done well, transforms your ISMS from a static collection of documents into a living, dynamic and increasingly resilient security system.
