Guidelines for Implementation

A successful ISMS requires leadership and commitment. Generally, top management (as defined by ISO/IEC 27000) is defined as an individual or group of individuals who are in charge of the ISMS’s management at the highest level – in other words, top management has general responsibility for the ISMS. It appears that top management directs the ISMS in a very similar way to the way budgets and expenditures are handled within the organization. The top management can delegate authority and supply resources within the organization to carry out activities related to information security and in turn, an ISMS, but it retains overall responsibility.

As an example, the organization implementing and operating the ISMS is often a branch of a larger corporation. In this case, top management consists of the individuals who direct and control the business unit. Managing directors also participate in management reviews and promote continuous improvement.

Following are ways in which top management should show leadership and commitment:

1. The organization’s top management should ensure that the knowledge security policy and, consequently, the information security objectives are carefully crafted and are consistent with the organization’s corporate strategy;

2. The top level of management needs to ensure the ISMS and controls are integrated into every aspect of the operation. It is best to tailor how this is accomplished to the specific needs of the organization. Corporate process owners, for example, can delegate to them or groups of employees the responsibility of implementing relevant requirements. Changes in controls and processes can also face resistance from top management if they are implemented without the support of top management;

3. The top management should ensure IT resources are available to implement an ISMS. Resource acquisition is necessary for establishing an ISMS, implementing it, maintaining and improving it, and implementing information security controls.

The ISMS requires the following resources:
– Having the necessary financial resources;
– Human resources;
– Equipment;
– Infrastructure technology.

Resource requirements depend on the organization’s context, such as its dimensions, complexity, and internal and external needs. The management review should provide information that indicates whether the resources are adequate for the organization;

4. The organization’s top leadership must communicate the need for information security management within the organization, so they should conform to ISMS requirements. To achieve this, practical examples that demonstrate what the particular needs are within the organizational context will be offered, as well as information security requirements;

5. Organizational leadership must ensure that the information security management system achieves its goal(s) by supporting the implementation of all information security management processes and particularly by requesting and reviewing ISMS status and effectiveness reports. Measuring, management reviews, and audit reports are often used to prepare such reports. Using the ISMS as a management tool, top management can set performance targets for key personnel;

6. The top management should not only direct but also support those within the organization who are directly involved with information security. If you do not try this, it will reduce the effectiveness of the ISMS. In addition to providing feedback on how planned activities align with the organization’s strategic needs, top management can also prioritize different activities within the Information Security Management System;

7. During management reviews, top management should assess the need for resources and set objectives for continuous improvement and monitor the effectiveness of implementation plans;

8. Managing information security should be a top priority, and top management needs to support the persons who are assigned to manage information security activities so that they’re motivated and ready to generate and manage information security activities. An ISMS applied and operated by an organization as a component of an even larger organization can often gain leadership and commitment from those who control and direct that larger organization. By gaining a thorough understanding of the ISMS implementation process, they will be able to provide support for top management within the ISMS scope and communicate their commitment to the ISMS. For example, if external interested parties are involved in the decision-making process regarding information security objectives and risk criteria, and their decisions regarding resource allocations are tied to the goals of the ISMS, their decisions are likely to reflect the ISMS’ goals.
