ISO/IEC 27001 Clause 5
Leadership – Driving ISMS Commitment
Clause 5 of ISO/IEC 27001:2022 focuses on the crucial role of top management in establishing, supporting, and governing the Information Security Management System (ISMS). It emphasizes that information security must be embedded in the organization’s culture and strategic direction, not treated as merely an IT issue.

Understanding Clause 5 – Leadership in ISO 27001
In practice, Clause 5 of ISO/IEC 27001:2022 means executives and department heads are accountable for the ISMS’s effectiveness. Without active leadership engagement, an ISMS can quickly become a check-the-box exercise rather than a living program that genuinely protects the organization. Clause 5 ensures that senior management visibly and materially supports information security, fostering a top-down security culture.
Clause 5.1 – Leadership and Commitment
Top management is required to demonstrate leadership and commitment to the ISMS. Clause 5.1 outlines several responsibilities that leaders must fulfill to show their support for information security. In summary, top management should:
- Set clear security policies and objectives: Establish an information security policy and define security objectives that align with the organization’s strategic direction and context. This ensures security goals complement overall business goals.
- Integrate ISMS into business processes: Embed ISMS requirements into day-to-day operations and processes. Information security shouldn’t operate in a silo; it must be a natural part of how the organization runs its projects, services, and workflows.
- Provide necessary resources: Allocate sufficient resources – including budget, skilled personnel, and technology – to implement and maintain the ISMS. Without adequate resources, even the best plans will falter.
- Promote security awareness: Actively communicate the importance of effective information security management and compliance with ISMS requirements. When leadership champions security, employees are more likely to follow suit and treat security as a priority.
- Ensure ISMS achieves its intended outcomes: Hold themselves accountable for the ISMS delivering results (such as risk reduction, compliance achievements, reduced incidents). This involves monitoring ISMS performance and making decisions to keep it on track.
- Empower and support personnel: Direct and support individuals to contribute to the ISMS’s effectiveness. This could mean assigning clear roles, providing training, and removing obstacles so that staff can carry out security responsibilities effectively.
- Promote continual improvement: Foster a culture of continuous improvement in information security practices. Top management should encourage regular reviews, audits, and updates to the ISMS to respond to evolving threats and business changes.
- Lead by example and delegate responsibly: Support other relevant managers in demonstrating leadership within their own areas. For instance, department heads should champion security in their teams. Top management’s job is to set the tone and empower these managers, creating an environment where everyone takes ownership of security.
Leadership not only meets Clause 5.1 requirements but also builds a strong foundation for a security-minded organizational culture.
Auditor’s note
During ISO 27001 certification audits, expect auditors to seek evidence of leadership commitment – e.g. signed policies, meeting minutes discussing ISMS performance, and records of resource allocations – to verify that Clause 5.1 is being met.
Clause 5.2 – Information Security Policy
An Information Security Policy is the cornerstone document that top management must establish under Clause 5.2. This high-level policy sets the direction for information security in the organization. According to ISO 27001:2022, the policy must meet several key criteria:
- Appropriate to the organization: The policy should be tailored to the organization’s purpose, size, and context. It must address the relevant business risks and regulatory environment. For example, a hospital’s policy may emphasize patient data confidentiality, whereas a tech startup’s policy might focus on cloud security and uptime.
- Include or frame security objectives: It should either contain the organization’s information security objectives or provide a framework for setting and reviewing them. (Note: Clause 6.2 of the standard details how to establish measurable security objectives – your policy should pave the way for those.)
- Commitment to requirements: The policy must affirm the organization’s commitment to satisfy applicable requirements related to information security. This includes compliance with laws (like GDPR, HIPAA), industry regulations, and contractual security obligations. By stating this, leadership shows it takes external and internal obligations seriously.
- Commitment to continual improvement: It should declare that the organization will continuously improve its ISMS. Given the ever-evolving threat landscape, a static security program is not enough – the policy anchors a mindset of ongoing enhancement and adaptation.
Additionally, Clause 5.2 requires that the information security policy be documented and communicated properly. The policy should exist as written, controlled information (often an approved PDF or intranet page) that is readily accessible. It must be communicated within the organization (e.g. through training or internal newsletters) so all employees are aware of it and understand their role in it. The policy should also be available to interested parties as appropriate – for instance, you might share it with clients, regulators, or partners upon request. This transparency can bolster trust with stakeholders by showcasing your leadership’s commitment to protecting information.
Practical guidance
Ensure the policy is formally approved by the highest authority (CEO or equivalent) to signal top management endorsement. Keep it concise, clear, and reflective of real practices – avoid generic platitudes. Many organizations use an Information Security Policy Template to kickstart this process, customizing it to fit their context while meeting all Clause 5.2 requirements.
Clause 5.3 – Organizational Roles, Responsibilities, and Authorities
Clause 5.3 ensures that everyone in the organization knows their part in keeping information secure. Top management must assign and communicate responsibilities for various aspects of the ISMS. In essence, this clause bridges strategy and execution by putting people in charge of the ISMS’s day-to-day and oversight tasks. Key mandates of Clause 5.3 include:
- Define ISMS roles clearly: Leadership should establish a robust structure for information security roles. This means identifying who will handle key ISMS functions – e.g., Who is accountable for the ISMS overall? (Often a CISO or Security Officer); Who conducts risk assessments? Who manages incident response? Who ensures compliance audits are done? Every role that influences information security should be documented along with its responsibilities. A well-defined RACI matrix (Responsible, Accountable, Consulted, Informed) or org chart can be helpful to visualize these assignments.
- Assign authority and competence: It’s not enough to name someone; they must also have the authority, resources, and competence to carry out their duties. For example, if you assign an IT manager to be responsible for access control, ensure they have the authority to enforce access policies and the training to do so effectively. Clause 5.3 expects that roles are assigned to competent persons and that the organization supports them (through training or empowerment) to fulfill their security responsibilities.
- Ensure internal awareness of roles: Those assignments must be communicated within the organization. Everyone should know who the go-to person is for various security areas. If an employee finds a security weakness, do they know whom to report it to? If a department needs a risk assessment, who leads it? Clarity prevents gaps and overlaps – much like an orchestra where each musician knows their part, avoiding chaos.
- Special mandated roles: ISO 27001:2022 explicitly calls out two critical responsibilities that must be assigned by top management:
- Ensuring ISMS conformance: Someone (or a team) must be tasked with keeping the ISMS aligned to ISO 27001’s requirements. This role monitors that all Clause 4-10 requirements are implemented and that the ISMS doesn’t fall out of compliance.
- Reporting on ISMS performance: A role must be assigned to report on the ISMS performance to top management. Typically, this means compiling reports or metrics on objectives, incidents, audit findings, etc., and presenting them in management review meetings (see Clause 9.3). This ensures leadership stays informed and can make strategic decisions based on how the ISMS is performing.
Document these roles in job descriptions, an ISMS manual, or a dedicated roles-and-responsibilities document. Not only does this aid internal clarity, it also serves as evidence for auditors that you have a system of accountability in place. Our ISO 27001 Roles and Responsibilities Template is one example of a tool to help ensure you cover all bases and can demonstrate compliance with Clause 5.3.
Why Leadership Matters for ISMS Success
Leadership involvement is not just a bureaucratic requirement – it’s a make-or-break factor for ISMS success. Here’s why Clause 5’s focus on leadership is so important:
- Security as a strategic priority: When top management treats information security as integral to business strategy, it gets the needed attention and alignment with business goals. This helps avoid the pitfall of viewing security initiatives as obstacles to operations; instead, they become enablers of trust, resiliency, and compliance that support business growth.
- Resource empowerment: Leaders control budgets and staffing. Their commitment translates directly into resources. An engaged leadership will ensure that the security team is well-funded, critical tools are purchased, and enough personnel are allocated to manage risks. Conversely, absent leadership often results in under-resourced security programs that leave vulnerabilities unchecked.
- Culture of security: Employees take cues from management. If executives lead by example – following security policies themselves, talking about the importance of cybersecurity in company meetings, and rewarding good security practices – it creates a ripple effect across the organization. A culture where every team member feels responsible for security vastly improves adherence to policies and quick reporting of incidents.
- Accountability and governance: Clause 5 essentially sets up a governance structure for the ISMS. This ensures there is oversight (through assigned roles and management reviews) and that security efforts are not happening in isolation. Leadership oversight means there’s accountability for meeting security objectives and addressing issues promptly. It also gives confidence to external parties (like clients or regulators) that security is taken seriously at the highest level.
- Audit and certification readiness: ISO 27001 auditors pay close attention to Clause 5 because it indicates whether the ISMS is likely to be sustainable. An ISMS lacking top-level support might succeed on paper but fail in practice. Demonstrable leadership commitment – evidenced by things like approved policies, active participation in risk assessments or incident reviews, and budgeting decisions – makes audits smoother and strengthens the case for (re)certification. Auditors often interview top management to gauge their involvement. Being prepared with leadership who can speak to the ISMS’s importance is a significant advantage.
Demonstrating Leadership Commitment (Best Practices)
Achieving compliance with Clause 5 is as much about behaviors and practices as it is about documentation. Here are some best practices and tips to help guide top management in fulfilling their leadership duties:
- Create a security governance forum: Establish a regular management meeting (monthly or quarterly) dedicated to ISMS matters. In these meetings, review security performance metrics, discuss incidents or near-misses, approve policies, and plan improvements. Document the minutes to show evidence of leadership oversight and decision-making.
- Appoint a champion (e.g., a CISO or Security Officer): If not already in place, designate a capable individual to lead the ISMS implementation. This person serves as the link between day-to-day security operations and the top management. They should have direct access to executives for reporting and consultation (fulfilling the Clause 5.3 reporting requirement). In smaller companies, this might be an IT manager or external Virtual CISO service – what matters is that they have leadership’s backing and ear.
- Integrate security into business plans: Require that all major business initiatives (new product launches, projects, partnerships, etc.) include an information security review as part of their planning. This fulfills the Clause 5.1 mandate of integrating ISMS into organizational processes and demonstrates that leadership wants security considerations in everything the organization does.
- Communicate from the top: Have the CEO or a top executive issue a company-wide statement (or periodic communications) about the importance of information security. For example, an annual security policy briefing from leadership or a personal email highlighting a recent security improvement can underscore commitment. This addresses Clause 5.1’s requirement to “communicate the importance of effective information security management” and can greatly influence employee attitude.
- Align security with objectives: Use the business’s language when talking about security at the leadership level. Show how the ISMS supports achieving business objectives (e.g., enabling sales by meeting customer security requirements, protecting intellectual property to maintain competitive advantage). This alignment, required by Clause 5.1 and 5.2, helps keep leadership engaged because security is seen as contributing to success, not just cost.
- Encourage leadership training & awareness: Ensure that not only staff but also top managers receive periodic briefings or training on emerging cyber threats, compliance changes, and their own responsibilities in the ISMS. A well-informed leadership is more likely to proactively drive necessary changes.
- Document leadership actions: Keep records of resources approved for security (budget line items, tool purchases), memos or announcements from leadership about security, and any management directives related to ISMS. During an audit, these artifacts collectively demonstrate that Clause 5 is woven into the fabric of management activities.
- Use tools and templates: Leverage policy templates, role matrices, and checklists (like those offered by CyberZoni) to ensure you’re covering all requirements. For example, a roles-and-responsibilities matrix helps verify you’ve assigned everything Clause 5.3 expects, and an information security policy template ensures you include all Clause 5.2 elements. These tools save time and provide a structure that aligns with the standard’s expectations.
By following these practices, organizations not only comply with Clause 5 but also reap the benefits of a well-led ISMS – one that is resilient, well-resourced, and respected across the enterprise. Remember that ISO 27001’s leadership requirements echo a simple truth: without management buy-in, security initiatives struggle. With engaged leadership, security becomes a driving force for trust and excellence in your organization.
Clause 5 in the 2022 Update
It’s worth noting that ISO/IEC 27001:2022 did not dramatically change Clause 5 from the 2013 edition – the core principles of leadership and commitment remain the same.
The 2022 update brought minor clarifications, such as a note explaining that references to “business” in the standard should be interpreted as the organization’s core activities. This simply reinforces that leadership commitment should span all parts of the organization, not just traditional business units.
Another small change was reordering sub-clauses and aligning terminology with Annex SL (the common structure for ISO management system standards), but if you were compliant with Clause 5 under ISO 27001:2013, you largely remain compliant under 2022.
Conclusion
ISO 27001 Clause 5 underscores that leadership is the driving force behind an effective ISMS. When top management is genuinely invested in information security, it sets the tone for the entire organization. With establishing a solid policy, assigning clear roles, providing resources, and continuously championing security efforts, leaders ensure that the ISMS not only exists on paper but thrives in practice.
