ISO 27001 Internal Auditor ISMS

The ISO 27001 Internal Auditor course teaches you to audit an ISMS: build the audit programme and plan, lead the audit interview, collect evidence, name nonconformities and write a report that management actually works with. You train in one group with the managers who implement the ISMS, so you test your audit against the arguments of the other side. The course includes sample forms, a risk analysis and register, audit plan and programme templates, an audit checklist with a set of audit questions and the structure of the final audit report.

Target Audience

For those who will audit the ISMS from the inside: internal auditors, members of security teams and everyone who has to take the organisation through a certification, surveillance or regulatory audit without surprises.

This intensive two-day course, led by practising lead auditors, teaches you to plan, conduct and report an internal audit of the information security management system according to ISO/IEC 27001 and ISO 19011. We do not stop at theory: on day two you practise both the audit and the risk assessment on a worked example.

The course is intended for

  • Internal auditors, including auditors of other management systems (ISO 9001, ISO/IEC 20000-1, ISO 22301) extending their qualification to information security
  • ISMS administrators and security managers who have to prepare the organisation for certification, a surveillance audit or recertification
  • Consultants and members of security teams who verify the effectiveness of implemented controls
  • People responsible for NIS2 and Act No. 264/2025 Coll. compliance who need to check and evidence it continuously
  • Candidates for the follow-up ISO 27001 Lead Auditor qualification

You share the group with participants of the ISO 27001 Foundation course, i.e. with the managers who implement and run the ISMS. For an auditor this is the ideal sparring partner: you hear how the other side of the table thinks about security, how it argues and what it can prove. An audit is a dialogue, and a dialogue is best learnt in two roles.

ISMS interní auditor

Aims

  • You plan an audit programme and prepare the plan of a specific audit, including scope, criteria and roles
  • You lead the audit interview, collect and evaluate evidence and distinguish a nonconformity from an observation and an opportunity for improvement
  • You write an audit report that corrective actions can follow, and you verify their effectiveness
  • You assess whether risk management according to ISO/IEC 27005 and the Statement of Applicability reflect the real state of the organisation
  • You evaluate compliance with NIS2 and the Czech Cyber Security Act and prepare the organisation for certification and surveillance audits

Benefits

The organisation gains an auditor who finds nonconformities before the certification body or the regulator does, and management gets a report it can base decisions on.

Why the course is useful

  • You handle internal ISMS audits with your own capacity: from opening through evidence collection to the report and verification of corrective actions
  • You remove the element of surprise from certification, surveillance and recertification audits, because you have been through them in a dry run
  • You use the internal audit as evidence of compliance with NIS2 and the Cyber Security Act towards the regulator, customers and suppliers
  • Audit findings become the engine of continual improvement of the organisation's security and resilience, supply chain included

ISMS documentation

Tip: audit against documentation that has passed through the hands of accredited auditors

The ISMS ISO 27000 Toolkit™ is a set of templates developed and field-tested by TAYLLORCOX's ISO/IEC 27001 auditors. An auditor finds in it a reference form of policies, the risk register or the Statement of Applicability to compare with the state of the audited organisation; an implementer gets a ready documentation base that only needs tailoring.

  • A complete set of ready-to-use templates for the whole ISMS
  • Fully adaptable to the size and sector of the organisation
  • Compatible with ISO 9001, GDPR and ISO 22301, so you audit one integrated system, not three
  • Saves weeks of work both in preparing for certification and during the audit

  • Summary and exam tips
  • Mock exam
  • Official ISO 27001 Internal Auditor exam

You spend both days in one group with participants of the ISO 27001 Foundation course. On day one you clarify the audit criteria: the requirements of ISO/IEC 27001, Annex A and the obligations that NIS2 and the Cyber Security Act impose on the organisation. Day two belongs to the auditor's craft according to ISO 19011: a practical example of conducting an audit from plan to report, and a practical example of risk management according to ISO/IEC 27005, which you assess as an auditor.

The course ends with the ISO 27001 Internal Auditor certification exam: first a mock exam, then the real one.

  • Block duration 90 minutes
  • Hours 16 hours
  • Refreshments Yes
  • Exam Yes
  • Prerequisites

    A basic orientation in information security is an advantage, not a condition: for example experience as a cyber security manager, auditor or architect, a completed ISO 27001 Foundation course or experience with audits of other management systems. On day one we introduce the standard and the legislation from the basics.

Jan Cuřín

A graduate of the Faculty of Electrical Engineering, Czech Technical University in Prague. Since 2005 he has worked as a lead auditor for accredited certification bodies for ISO/IEC 27001, ISO/IEC 20000-1, ISO 9001 and ISO 50001, with dozens of certification and surveillance audits in public administration, healthcare, telecommunications, energy and banking, including audits abroad. As a consultant he has prepared a number of companies for ISO/IEC 27001 certification, he has audited bank identity services under the eIDAS regulation and since 1989 he has been a court-appointed expert witness in computing and economics. At TAYLLORCOX he teaches ISO 27001, the Czech Cyber Security Act and GDPR, and he also trains the auditors of certification bodies: so in his course you hear exactly what a certification audit will ask.

What is his course like?

No reading the standard aloud. He presents every ISO/IEC 27001 requirement the way an auditor verifies it: what evidence the auditor wants to see, where companies most often fail and what is a minor finding that can be fixed within a week. Participants leave prepared not only for the exam, but with a realistic picture of how to pass a certification audit and how to lead one themselves.

  • Lead Auditor ISMS ISO/IEC 27001, ITSM ISO/IEC 20000-1 and ISO 9001 for accredited certification bodies
  • Certified Cyber Security Manager, Auditor and Architect under the Czech Cyber Security Act; Approved Trainer & Lead Auditor GDPR
  • Risk Manager ISO/IEC 27005, court-appointed expert witness in computing and economics

Petra Dytrychová

A graduate of the Czech Technical University in Prague. For more than six years she managed the management systems at České Radiokomunikace, where, as the company's only Lead Auditor, she led internal ISMS audits under ISO/IEC 27001, ISO/IEC 20000-1 and the Czech Cyber Security Act in an environment of electronic communications, digital infrastructure and cloud services with high demands on availability and regulatory compliance. In 2024 she single-handedly guided Cloud4Com to a successful ISO/IEC 27001 certification. At TAYLLORCOX she trains and audits ISO 27001, NIS2 and the new Czech Cyber Security Act: not only what the standard says, but how to implement it so that it stands up to the certification audit and to everyday operations.

  • Lead Auditor ISMS ISO/IEC 27001, ISO/IEC 20000-1 and the Czech Cyber Security Act
  • Certified Cyber Security Manager and Cyber Security Auditor under NIS2, Act No. 264/2025 Coll. and Decree No. 409/2025 Coll.
  • Lead Auditor ISO/IEC 42001 (AI Management System)

Zuzana Bitterová

For more than fifteen years she has managed information security, risk management and data privacy in international corporations in the Czech Republic and the United Kingdom, from electronics and energy to pharmaceuticals and the public sector. She headed service operations for the UK and Ireland, including business continuity plans and their testing, assessed the cyber security of global suppliers and designed and delivered cyber security risk management courses for UK government institutions based on the NCSC framework. She is a CISM, an ISO/IEC 27001 Lead Auditor and Lead Implementer and an ISO 22301 Business Continuity Manager, holds a Senior Executive MBA and is pursuing a PhD in information security at Royal Holloway, University of London. She speaks at international conferences (GISEC, #RISK, PrivSec, ISACA London) and at TAYLLORCOX she teaches ISO 27001, ISO 27005 Risk Manager and ISO 22301 with the perspective of a practitioner who does not just audit the standards but has implemented them in corporations herself. She teaches in Czech and English.

What is her course like?

She teaches ISO 27001 the way it is used in the boardroom and in IT: from risk analysis through the selection of controls to the evidence an auditor wants to see. She brings in cases from corporations, supply chains and the UK public sector, where she dealt with cyber risks for real, and leads participants to be able to defend the standard in front of their management and the certification body alike.

  • Senior Executive MBA (Nottingham Trent University), PhD candidate in Information Security (Royal Holloway, University of London), member of ISACA, (ISC)² and BCS

Vladimír Ráb

For twenty years he worked where IT really breaks: he administered thousands of servers, designed networks for T-Mobile, built branch infrastructure from Ukraine to India and managed the migration of 60,000 computers for Société Générale. DHL contracted him into its security teams three times. He therefore knows ISO/IEC 27001 from both sides: as the infrastructure administrator whose door the audit knocks on, and as a certified Cyber Security Manager, Auditor and Architect under the Czech Cyber Security Act.

What is his course like?

He does not read the standard to you, he shows it in operation. He turns every Annex A control into a concrete setting: what access control that satisfies an auditor looks like, what logging you can actually investigate an incident from involves, and how to spot a backup nobody has ever restored. As a Certified Ethical Hacker and a Certified EC-Council Instructor he adds the attacker's view: why a given control is in the standard at all and what happens when it is missing.

On top of that, three things an online course cannot offer: teaching in Czech, groups of 7 to 12 people and dialogue. You can ask about situations from your own company and get an answer from someone who has most likely dealt with a similar one. He trains both technicians and company management, mainly in banking and telecommunications: he can present the same topic to server administrators and to the board's security committee alike.
