In today's landscape of growing threats from cyberattacks, data breaches, and increasingly stringent regulations, information security should be a top priority for every business.

The Federal Criminal Police Office (Bundeskriminalamt, BKA) recorded 136,865 cyberattacks last year, resulting in significant financial losses. In response, the ISO 27001 standard provides companies with measures to protect their information assets securely. Information security is a critical concern. How can we ensure that our information systems are adequately protected?

What exactly is ISO 27001, and what steps can companies take to enhance information security successfully? In our overview, you'll find key information and a guide through the essential measures of ISO 27001.

Information security essentials at a glance:

  • ISO 27001 is an international security standard for information security.

  • It provides a framework for building, implementing, and maintaining an Information Security Management System (ISMS).

  • An ISMS is a framework of policies and procedures to minimise operational risks.

  • ISO 27001 relies on best practices and proven security strategies for maintaining information security in organisations.

What is ISO 27001?

ISO 27001 is the internationally recognised standard for regulating information security in businesses. It offers guidance for building, implementing, maintaining, and continuously improving an information security management system (ISMS), supporting organisations in protecting their information assets.

In 2022, the ISO 27001 standard underwent its third major revision, resulting in the current version, ISO 27001:2022.

Definition of ISO 27001: Who is responsible?

The official title of the German version is currently DIN EN ISO/IEC 27001:2022 Information Security, Cybersecurity, and Data Protection – Information Security Management Systems – Requirements (ISO/IEC 27001:2022). This version is still in draft. The standard is jointly issued by the International Standardization Organization (ISO) and the International Electrotechnical Commission (IEC).

ISO and IEC: What does it mean?

ISO stands for the International Standardization Organization, an international, independent association of national standardization organisations from 167 member states (as of 2022). Its role is to develop and publish standards for almost all areas.

The International Electrotechnical Commission (IEC) is also an international standardisation organisation focusing exclusively on electricity, electronics, and related technologies. To create internationally valid standards for information and communication technology, ISO and IEC have established a joint technical committee (JTC).

Why ISO 27001? The purpose of certification

ISO 27001 serves as the standard for information security, recognised internationally. It provides organisations, regardless of size or industry, with recognized guidelines, procedures, and controls to mitigate the risk of information security breaches.

Risks include:

  • physical hazards (fire and resulting data loss)

  • risks from employees (insufficient training or negligent handling of data or intentional data theft)

  • system and process risks from outdated software

  • danger of cyberattacks or ransomware.

ISO 27001:2022 specifies measures for all organisational, personal, physical, and technological risks, allowing organisations to implement targeted and structured data and information protection.

As challenges in information security increase in 2023 – with hackers developing new methods, rising attack numbers, and a shortage of skilled professionals – read our article on how to best prepare.

What is the difference between ISO 27001:2013 and ISO 27001:2022?

In 2022, the international standard ISO 27001 was revised again, now as the 2022 version. This revision included significant and long-overdue changes. In August, ISO/IEC 27001:2022 was published by the International Accreditation Forum (IAF), replacing the previous ISO 27001:2013.

The controls were revised, supplemented, and reorganised in the 2022 version, alongside a name change and editorial adjustments. 114 controls and 14 categories were reduced to 93 controls in four categories. Additionally, eleven controls were added. Learn more in our chapter on ISO 27001 Controls in Annex A.

What impacts does ISO 2022 have on companies?

The changes in the new ISO 2022 are noticeable, but there's no need to worry. A complete change in the approach is not required. Instead, the adjustments align with a growing understanding of information security.

Important to note: a 36-month transition period, during which certified companies can adapt their measures to the new version for recertification. This aligns with the regular audit process, as certified organisations must repeat their audit every three years to remain certified.

Key dates:

The ISO 27001:2022 was published on October 25, 2022. The transition period has been set at three years (36 months). As a result, end-users have the following timeframes and deadlines for the transition:

Certification readiness for ISO/IEC 27001:2022:

Expected from February to April 2023 (dependent on the German Accreditation Body GmbH).

Last date for initial and recertification audits under the previous ISO 27001:2013:

Until April 30, 2024.

Transition of all existing certificates to the new ISO/IEC 27001:2022:

Three years, based on the last day of the issuance month of ISO/IEC 27001:2022 (October 2025).

This means all documentation must be adapted and updated to the new controls before the next re-audit. Once the preparations for the new version are appropriately adjusted, the next audit can easily be used to transition to certification under ISO 27001:2022.

ISO 27001: Who is the norm important for?

Information security is relevant in almost every company, making ISO 27001 crucial for nearly every organisation that handles information and data. But what exactly is the ISO 27001 certification, and who does it concern?

ISO 27001 certification: What is it?

ISO 27001 certification confirms that your organisation meets the requirements of the ISO 27001 standard. Suppose you have established your Information Security Management System (ISMS) according to ISO 27001 guidelines. In that case, an independent accredited certification body conducts an audit and confirms your results with an ISO 27001 certificate upon successful completion.

Who needs ISO 27001 certification?

While ISO 27001 certification is not mandatory, it is common practice and, above all, a requirement for important business relationships. Without transparent guidelines and measures for risk management in your organisation, your information is at risk.

Certain industries, particularly those threatened by cyberattacks and ransomware, consider ISO 27001 application to be the norm. The most revenue has been lost in these industries since 2019:

  • High Tech

  • Biotechnology

  • Automotive Industry

  • Consumer Goods and Services

  • Banking

  • Health

  • Retail

  • Insurance

  • Mechanical Engineering

  • Communication and Media

However, given the rise in cybercrime, all companies - from SMEs to large corporations - need to consider their information security. The ISO 27001 controls provide a clear roadmap for businesses to prioritise their information security.

Benefits of ISO 27001

Clearly, identifying and addressing security risks is beneficial for any business. The ISO 27001 controls play an essential role in clearly categorising potential risks. But what are the specific benefits of mitigating risks?

Build trust with all stakeholders

ISO 27001 equips organisations with the information they need to protect valuable data by applying good information security practices. ISO 27001 compliance assures customers, partners, and key stakeholders that the organisation has taken the necessary security measures to treat valuable information and sensitive data appropriately.

Protect organisations from data breaches

The ISO 27001 standard defines policies and procedures for security measures that, when implemented, protect an organisation from unauthorised access to its data and complete data loss.

By implementing the proposed measures, the risk of data breaches or fines for such incidents is also reduced. The guidelines cover information security across all areas.
However, it is important to note that ISO 27001 does not offer an absolute guarantee against security incidents or data breaches. However, it creates a framework to reduce the likelihood of such incidents and strengthen an organisation's ability to respond appropriately. The precise implementation and effectiveness of the measures depend on the individual organisation and its environment.

If data is compromised in any way, the ISO 27001 standard sets out procedures for responsible and effective incident management.

Protect the personal data of employees

Under ISO 27001, not only sensitive data from third parties but also the personal data of employees of an organisation is protected. An organisation is required to disclose the information security measures it has taken to all parties so that they are aware of them, agree with them, and can consent to them.

This is one of the prerequisites for an organisation to be considered compliant with industry guidelines and work instructions under this standard.
Trust and security in the company and the protection of important data also provide some competitive advantages.

Risks are avoided - business deals are potentially increased

In general, certified companies are more convincing in the perception of their business partners than non-certified competitors and conclude new business contracts more efficiently. Of the many other advantages, these are just a few:

  • Improved competitiveness

  • Significantly reduced risk of fines and financial losses due to data breaches

  • Brand perception is constantly improving.

  • Achieving compliance in all areas (business, legal, economic, and legal)

  • Improved structure and focus

  • The number of required audits decreases

  • You receive an unbiased assessment of your security situation.

To this end, every organisation and company is encouraged to establish an information security management system (ISMS) - an efficient, technology-independent, risk-based means of securing information values based on regular information security assessments (ISAs) for risk assessment.

What is an ISMS?

An information security management system (ISMS) is a management system for protecting the information security of an organisation or company. It consists of a series of measures that an organisation should implement to:

  • Know who their stakeholders are and what expectations they have regarding the information security of their organisation.

  • Know what risks the information is exposed to.

  • Achieve the defined requirements and, to do so, manage the risks, develop measures (security mechanisms) and establish other strategies for damage mitigation.

  • Define clear goals, which minimum measures are to be taken with regard to information security.

  • Implement all necessary measures and other strategies for risk mitigation.

  • Regularly check to what extent the measures put in place are working as planned.

  • Make continuous improvements to the overall performance of the ISMS.

In general, the following benefits arise for an organisation from a certified ISMS:

  • Compliance with legal requirements

  • Competitive advantages over competitors

  • Cost reduction or elimination

  • Improved organisational structure

Having the ISMS certified according to ISO 27001 is essential in some industries when it comes to the conclusion of large contracts. The certification strengthens the trust of all business partners and thus contributes to the expansion of business opportunities.

ISO 27001 has now become the "gold standard" for management systems for information security. It is used in many organisations as an integral part of their IT governance, risk, and compliance management procedures.

Now that we have clarified the term ISMS let's look at how the ISO 27001 framework is used and how the two are connected.

How does ISO 27001 work?

ISO 27001 is an approach to information that focuses on risks, data protection, and cybersecurity. Its primary concern is to identify risks to information security and systematically address them through control measures.

The ISO 27001 standard is divided into so-called clauses (clauses) and controls (measures) to structure the predefined framework clearly.

ISO 27001 Clauses: What is it and what are there?

ISO 27001 is the international standard for the implementation of information security. But how do companies apply the standard, and what are the requirements?

This information is regulated in the clauses and controls. The clauses explain the standard and provide a detailed overview of the requirements. They are the framework organisations use to meet the standard's requirements.

General Clauses

  • Clause 0: Introduction

  • Clause 1: Scope

  • Clause 2: Normative references

  • Clause 3: Terms and definitions

Clauses 0 to 3 provide general guidance and introduce the standard and its terminology. Clauses 4 to 10 specify an organisation's requirements for certification.

Clause 4: Context of the organisation

This clause emphasises the importance of considering the context in which an organisation operates. Only the context of the organisation determines the scope for the ISMS. The requirements can go beyond regulatory aspects. Companies should identify the context, determine the relevant requirements, and take them into account in their planning.

In addition, an important point from Clause 4 is that an organisation must establish, implement, maintain, and continually improve an information security management system, including the required processes and their interactions, in accordance with the requirements.

Clause 5: Leadership

The most critical component for the success of an ISMS is the unreserved commitment of the top management. The clause requires the organisation to establish an information security policy in which the goals, roles, responsibilities, and authorities in the field of information security are clearly defined and aligned with the organisation's strategic direction. Resources must also be provided, and the requirements of the ISMS must be integrated into the organisation's business processes.

Explore our comprehensive ISO 27001 Documentation Toolkit to efficiently streamline the creation of your Information Security Policy and enhance your ISMS implementation strategy.

Clause 6: Planning

When planning an ISMS environment, the following should be considered: The information security goals should be based on the risk assessment and be consistent with the general organisational goals. Likewise, all those involved in the organisation should align their activities with these security goals.

In addition, the opportunities through an ISMS must also be determined, and the topics defined in Clause 4 must be considered.

Clause 7: Support

The support clause of ISO 27001 focuses on the people and processes that are essential to the success of an ISMS. It requires organisations to:

  • Create awareness of information security: Employees must understand the importance of information security and their role in protecting it.

  • Provide training and education: Employees must have the skills and knowledge they need to implement and maintain the ISMS.

  • Communicate effectively: Organisations must communicate information security policies and procedures to all employees.

  • Obtain commitment: Employees must be committed to following information security policies and procedures.

  • Provide resources: Organisations must provide the resources necessary to support the ISMS, such as training, equipment, and funding.

  • Document information: Organisations must document all relevant information about the ISMS, such as policies, procedures, and records.

Clause 8: Operation

The operation clause of ISO 27001 focuses on the day-to-day activities of an ISMS. It requires organisations to:

  • Plan and control processes: Organisations must plan and control the processes that are necessary to meet the requirements of the ISMS.

  • Conduct regular security assessments: Organisations must conduct regular security assessments to identify and mitigate risks to information security.

  • Implement security controls: Organisations must implement security controls to mitigate the risks identified in the security assessments.

Clause 9: Evaluation

The evaluation clause of ISO 27001 focuses on the ongoing monitoring and improvement of an ISMS. It requires organisations to:

  • Conduct internal audits: Organisations must conduct internal audits to assess the effectiveness of the ISMS.

  • Review the ISMS: Organisations must review the ISMS at planned intervals to ensure that it is still meeting the organisation's needs.

Clause 10: Improvement

The improvement clause of ISO 27001 focuses on the identification and implementation of improvements to an ISMS. It requires organisations to:

  • Identify and address non-conformities: Organisations must identify and address any non-conformities that are identified during internal audits or other evaluations.

  • Review the effectiveness of security controls: Organisations must review the effectiveness of security controls to identify opportunities for improvement.

ISO 27001 certification and GDPR compliance are crucial to ensure our company's long-term success.

ISO 27001:2022 Controls: What measures are included in Annex A?

The controls outlined in ISO 27001 Annex A are the measures the standard provides to empower businesses in significantly reducing risks. The selection of measures by an organisation is determined based on previously identified risks. Using this foundation, the focus is established, and relevant categories are chosen.

As of 2022, there are a total of 93 controls divided into four categories. Eleven of these controls were newly added to ISO 27001 in 2022. The four categories each describe the focus area of the controls' application.

ISO 27001:2022: Eleven new controls

Since 2022, ISO 27001 has incorporated eleven new controls, each assigned to distinct categories:

A.5.7 Threat intelligence

The "Threat intelligence" measure obligates companies to collect data on potential threats to information security and subject it to in-depth analysis.

A.5.23 Information security for the use of cloud services

Following the "Information security for the use of cloud services" measure, companies are urged to establish and manage information security for the utilisation of cloud services.

A.5.30 ICT readiness for business continuity

Companies must create an ICT continuity plan to maintain operational resilience, fulfilling the "ICT-readiness for business continuity" measure.

A.7.4 Physical security monitoring

Companies need to employ suitable monitoring tools for the "Physical security monitoring" measure to detect and prevent external and internal intrusions.

A.8.9 Configuration management

During "Configuration management," companies must establish guidelines for the documentation, implementation, monitoring, and review of configurations across their entire network.

A.8.10 Information deletion

The document "Information deletion" contains instructions for managing data deletion to comply with laws and regulations.

A.8.11 Data masking

"Data masking" provides techniques for masking personal identifiable information (PII) to comply with laws and regulations.

A.8.12 Data leakage prevention

Following the "Data leakage prevention," companies must take technical measures to detect and prevent the disclosure and/or extraction of information.

A.8.16 Monitoring activities

The "Monitoring activities" measure provides guidelines to enhance network monitoring activities to detect anomalous behaviour and respond to security events and incidents.

A.8.23 Web filtering

Companies must enforce access controls and measures for "Web filtering" to restrict and control access to external websites.

A.8.28 Secure coding

Companies are mandated to implement best practices of secure coding to prevent vulnerabilities caused by inadequate coding methods.

Controls according to ISO 27001: The four categories

The ISO 27001:2022 standard contains 93 controls, which are assigned to four categories: organisational, people, physical, and technological. The grouping of controls into four thematic areas helps organisations to decide who is responsible for implementing the measures and which measures are relevant to the context of the organisation. Each category can be assigned to a specific focus area within your organisation. This makes it easier to apply the relevant controls selectively to your organisation.

Organisational controls (37 measures)

These controls are applicable when the risks do not fall under the topics of people, technology, or physical security. They include, for example, identity management, responsibilities, and evidence collection.

New organisational controls include:

  • 5.7: Threat intelligence

  • 5.23: Information security for the use of cloud services

  • 5.30: ICT readiness for business continuity

Threat intelligence is a significant innovation in this area. This measure goes beyond the detection of malicious domain names. Threat analysis helps organisations better understand how they can be attacked and take appropriate precautions.

People controls (8 measures)

Remote work is a hot topic in the people area. However, the restructuring of the working world also comes with risks. This is where the people measures of ISO 27001 come in. The area related to personnel only includes eight controls. These focus on how employees handle sensitive information during their daily work. This includes topics such as remote work, non-disclosure agreements, and screenings. In addition, onboarding and offboarding processes and responsibilities for reporting incidents are relevant.

Physical controls (14 measures)

Physical controls include security monitoring, maintenance, facility security, and storage media. This category is about how you protect yourself against physical and environmental threats such as natural disasters, theft, and intentional destruction.

New physical controls include:

  • 7.4: Physical security monitoring

Technological controls (34 measures)

Technology must also be properly secured to protect information. Technological controls, therefore, deal with authentication, encryption, and data leakage prevention. This can be achieved through various approaches, such as access rights, network security, and data masking.

New technological controls include:

  • 8.1: Data masking

  • 8.9: Configuration management

  • 8.10: Information deletion

  • 8.12: Data leakage prevention

  • 8.16: Activity monitoring

  • 8.23: Web filtering

  • 8.28: Secure coding

One innovation in this area is particularly important: data leakage prevention. Web filtering is also helpful: This control describes how organisations should filter online traffic to prevent users from visiting potentially harmful websites.

Controls with the greatest potential for error

Information security is no longer a niche topic - it is the foundation for resilience, success, and growth for any business. Many businesses require their business partners and suppliers to be certified to an information security standard such as ISO/IEC 27001, which specifies the requirements for an information security management system (ISMS).

However, implementing ISO 27001 without a structured plan can be a major challenge. Based on our work with customers in a variety of industries, we have compiled the four most common mistakes that occur when implementing controls according to ISO 27001 - as well as tips on how your organisation can avoid these common mistakes.

Before we dive in, let's take a quick look at the controls that ISO 27001 requires.

ISO 27001 has a total of ten main chapters, as well as four control catalogues in Annex A, which together cover 93 detailed objectives for controls. These controls cover areas such as cryptography, compliance, and operational security.

In summary, Annex A can be understood as a catalogue of individual security requirements. How you respond to these requirements when building your ISMS depends on the type of your organisation.

So, let's take a look at some of the most challenging controls that an organisation must implement - supplier security, operational security, communications security, and asset management.

Is ISO 27001 mandatory for businesses?

The ISO 27001 standard recognises the diversity of information security needs and requirements in each organisation. It suggests that security measures should be tailored to the individual organisation. While ISO 27001 compliance is not mandatory everywhere, some countries require compliance for certain industries.

Both public and private organisations have the option to require ISO 27001 compliance from partners and suppliers as a contractual condition in their contracts and agreements. Similarly, countries can require and ensure the protection of citizen data by organisations operating in their country through ISO 27001 compliance. This can vary by country and industry.

How to achieve ISO 27001 compliance? - Our checklist

Even if they are not pursuing formal certification, organisations always have the option to pursue compliance with the ISO 27001 standard requirements. The following list shows which best practices you should best implement to do this and can be used very well as a checklist:

  • Identify the expectations of your stakeholders regarding information security through conversations with them.

  • Define the scope of your ISMS and the information security measures.

  • Define a clear security policy.

  • Conduct a risk assessment to identify any existing and potential risks to your information security.

  • Implement measures and risk management methods that set clear objectives.

  • Continuously evaluate the effectiveness of your information security practices and conduct regular risk assessments.

Checklist: ISO 27001 Compliance

Breaking down the path to ISO 27001 compliance into individual steps, the journey looks as follows:

  1. Prepare thoroughly

    While reading the standard, you gain valuable insights into ISO 27001 and its requirements. Additionally, there are numerous opportunities to further educate yourself on ISO 27001.

    You can download a detailed implementation roadmap from us for free, discussing the norm extensively.

  2. Define your context, scope, and objectives

    As a central criterion for success, it has proven effective to first establish project and ISMS objectives, along with the associated budget and timeframe. At this point, a decision is needed on whether to internally possess the necessary expertise and resources for implementation or to engage a consultant.

  3. Involve management properly and early

    An organisation's management framework defines all the procedures to achieve its ISO 27001 implementation goals. Accountability, specifying who in management is responsible for the ISMS, a schedule of all activities, and regular ISMS reviews for effectiveness are mechanisms cyclically ensuring ISMS improvement.

  4. Conduct a risk assessment

    While ISO 27001 requires a formal risk assessment, it does not prescribe a methodology. "Formal" implies that the risk assessment approach is planned in advance, and the associated data, analyses, and results are documented.

  5. Implement risk treatment measures

    The organisation's task is to determine how to proceed with the identified risks. Should they be avoided, transferred, accepted, or mitigated? All decisions made for risk treatment must be documented. During a registration or certification audit, an auditor will want to see this documentation. If you choose to mitigate risks, it is crucial to implement the measures, based on ISO 27002 controls, for example.

  6. Review and update the related documentation

    Documentation is one of the requirements you cannot bypass with ISO 27001. You must document all processes, rules, and procedures related to your ISMS to ensure their appropriate implementation. The norm requires documentation of the following aspects:

    • Understanding the organisation and its context (e.g., through an environmental analysis)

    • Identification of interested parties

    • ISMS scope

    • Communicated management commitment

    • Roles and responsibilities within the ISMS

    • Risk and opportunity management

    • Change management planning

    • Resource planning

    • Decision logs related to risk management

    • Training

    • Communication matrix

    • Documentation management planning/policy

    • Framework with information security policies and information security guidelines

    • Procedure for information security risk management

    • Statement of Applicability (SoA)

    • Information security objectives

    • Evidence of competence

    • Information necessary for the organization's ISMS effectiveness

    • Control and planning of activities

    • Evidence of monitoring and measurement results and evaluation

    • Procedure for internal audits

    • Procedure for management review

    • Evidence of the audit program and its results

    • Evidence of the results of management reviews

    • Evidence of the type of identified non-conformities and all subsequent actions

    • Evidence of the results of all corrective and improvement actions taken

  7. Evaluate yourself – Measure, track, and assess

    Continuous improvement is one of the cornerstones of ISO 27001. To achieve this, you must understand how effective your ISMS measures are and how ISMS-compliant your organisation operates. Ongoing monitoring and analyses reveal which of the existing processes and measures require changes.


  8. Conduct an internal audit

    Internal audits of your ISMS are to be regularly conducted according to ISO 27001. The internal auditor conducting the audit of ISO 27001 compliance needs practical knowledge of the approach as a Lead Auditor, ensuring objectivity and impartiality.

    At this point, ISO 27001 certification is also a viable option if your organisation has already achieved full compliance—especially if you have adhered to best practices and your organisation's information security procedures already align with the norm's requirements.

How much does ISO 27001 certification cost?

The cost question regarding ISO 27001 certification cannot be answered universally. It holds true: the more complex the requirements, the more elaborate the preparation. Costs vary based on needs and the level of implementation. Project duration, the use of internal resources, the scope of existing infrastructure, and the size of your company all influence cost estimates.

Factors influencing cost estimation include:

  • Organisation size and complexity of information processes

  • Application areas of the ISO 27001 certificate

  • Maturity level of the existing ISMS

  • Discrepancy size between the current status and the target status for the control system
  • Internal resources for ISO 27001 implementation

  • Timeframe available for certification

  • External consultation

  • Costs for external audits by a certification body

For a detailed breakdown of costs, refer to our guide on the costs of ISO 27001 certification.
