The Role of Top Management in ISMS

An Information Security Management System (ISMS) is a structured approach that an organization uses to manage and protect its assets. It provides a framework for identifying, assessing and mitigating information security risks, ensuring the confidentiality, integrity and availability of information. ISO/IEC 27001:2022 standard provides the requirements for establishing, implementing, maintaining and continually improving the ISMS of an organization. The standard identifies the top management of an organization as the main driver for ISMS initiatives and bestows several responsibilities on them.

In this article, we analyse the roles and responsibilities of top management with respect to ISMS.

Demonstrating Leadership and Commitment

Top management needs to be involved in the key planning stages of the ISMS. They must establish its scope by considering relevant issues that may impact information security aspects, and the requirements of stakeholders. Top management needs to demonstrate leadership and commitment by doing the following:

• Establishment of security policy and objectives – The information security policy and objectives should align with the organization’s long-term strategy and goals. The policy should be communicated within the organization and made available to relevant stakeholders. Examples of information security objectives are: ensuring integrity of customer data, ensuring confidentiality of transmitted data, maintaining regulatory compliance etc.

• Establishment of ISMS-compatible processes – The organization’s processes should consider the requirements of ISMS. For example, information security risk assessment is an important ISMS requirement. The organization must establish an information security risk assessment process that produces results which are consistent, valid and comparable. Risks need to be assessed at planned intervals and when such changes occur which are significant to the ISMS. Moreover, the identified risks need to be managed as per the organization’s risk treatment plan.

• Arrangement of resources – All resources that are needed for ISMS should be made available. Examples include suitable infrastructure, security controls and personnel who are competent enough to implement the security processes and controls. Top management should make provisions for the procurement / acquisition of all resources so that they are available as and when required.

• Maintenance of effective ISMS – The importance of an effective ISMS needs to be communicated to stakeholders and they should be directed to contribute to its effectiveness. It must be ensured that the ISMS achieves its intended outcomes. For example, security personnel must be trained on the implementation and usage of appropriate security controls so that they can achieve their purpose.

• Instillation of leadership qualities – Relevant personnel should be encouraged to demonstrate leadership in their respective areas. Top management can identify personnel who can be groomed for leadership roles. They should be provided with training and support so that they can coordinate security tasks and oversee the implementation of ISMS within their areas of responsibility.

• Continual improvement – The ISMS needs to be continually improved. Top management should make arrangements for measuring the effectiveness of ISMS and conducting periodic audits and reviews. The results should be analyzed to determine ways of continually improving the ISMS. For example, repeated malware attacks might indicate an ineffective anti-malware system. It should be reviewed and corrections / corrective actions must be planned and implemented to prevent further attacks.

  
  

Defining Roles and Responsibilities

Top management needs to define information security roles and assign responsibilities and authorities to those roles. It is important to communicate these within the organization. Responsibilities should be defined to ensure that the ISMS meets the requirements of ISO/IEC 27001:2022 standard, and that the performance of ISMS is reported to top management.

Reviewing ISMS

Top management must review the organization’s ISMS at specific intervals in order to ensure its continuing suitability, adequacy and effectiveness. During the management review meetings, the following inputs should be considered:

• the actions taken with respect to the results of previous management reviews;

• the changes in relevant issues, and requirements of stakeholders, which may impact information security aspects;

• the performance of ISMS as is evident from non-conformities and corrective actions, security metrics, audit results and fulfilment of information security objectives;

• stakeholders’ feedback on ISMS;

• risk assessment results and status of risk treatment plan; and

• any opportunities for improvement.

Top management should decide whether any changes are needed to the existing processes and how to continually improve the ISMS. It is important to carry out all changes in a planned manner.
