4.2.2 Information
Information is an asset that, like other important business assets, is essential to an organization’s business and, consequently, needs to be suitably protected. Information can be stored in many forms, including: digital form (e.g. data files stored on electronic or optical media), material form (e.g. on paper), as well as unrepresented information in the form of knowledge of the employees. Information can be transmitted by various means Including: courier, electronic or verbal communication. Whatever form information takes, or the means by which it is transmitted, It always needs appropriate protection.
In many organizations, information is dependent on information and communications technology. This technology is often an essential element in the organization and assists in facilitating the creation, processing, storing, transmitting, protection and destruction of information.
4.2.3 Information security
Information security ensures the confidentiality, availability and integrity of information. Information security involves the application and management of appropriate controls that involves consideration of a wide range of threats, with the aim of ensuring sustained business success and continuity, and minimizing consequences of information security incidents.
Information security is achieved through the implementation of an applicable set of controls, selected through the chosen risk management process and managed using an ISMS, Including policies, processes. procedures. organizational structures, software and hardware to protect the identified information assets. These controls need to be specified, implemented, monitored, reviewed and improved where necessary, to ensure that the specific information security and business objectives of the organization are met. Relevant information security controls are expected to be seamlessly integrated with an organizalion’s business processes.
4.2.4 Management
Management involves activities to direct, control, and continually improve the organization within appropriate structures. Management activities include the act, manner, or practice of organizing, handling, directing, supervising, and controlling resources. Management structures extend from one person in a small organization to management hierarchies consisting of many individuals in large organizations.
access to and handling of information. In addition, the distribution of mobile storage devices containing information assets can weaken the effectiveness of traditional controls. When organizations adopt the ISMS family of standards, the ability to apply consistent and mutually-recognizable information security principles can be demonstrated to business partners and other interested parties.
Information security is not always taken into account in the design and development of information systems. Further, information security is often thought of as being a technical solution. However, the information security that can be achieved through technical means is limited, and can be ineffective without being supported by appropriate management and procedures within the context of an ISMS. Integrating security into a functionally complete information system can be difficult and costly. An ISMS involves identifying which controls are in place and requires careful planning and attention to detail. As an example, access controls, which can be technical (logical), physical, administrative (managerial) or a combination, provide a means to ensure that access to information assets is authorized and restricted based on the business and information security requirements.
The successful adoption of an ISMS is Important to protect information assets allowing an organization to:
a) achieve greater assurance that its information assets are adequately protected against threats on a continual basis;
b) maintain a structured and comprehensive framework for identifying and assessing information security risks, selecting and applying applicable controls, and measuring and improving their effectiveness;
c) continually Improve its control environment; and
d) effectively achieve legal and regulatory compIiance
4.5 Establishing, monitoring, maintaining and improving an ISMS
4.5.1 Overview
An organization needs to undertake the following steps In establishing, monitoring, maintaining and improving its ISMS:
materializing to information assets, and the potential Impact of any information security incident on information assets. The expenditure on relevant controls is expected to be proportionate to the perceived business impact of the risk materializing.
4.5.3 Assessing Information security risks
Managing information security risks requires a suitable risk assessment and risk treatment method which can include an estimation of the costs and benefits, legal requirements, the concerns of stakeholders. and other inputs and variables as appropriate.
Risk assessment should identify, quantify, and prioritize risks against criteria for risk acceptance and objectives relevant to the organization. The results should guide and determine the appropriate management action and priorities for managing information security risks and for implementing controls selected to protect against these risks.
Risk assessment should include:
— the systematic approach of estimating the magnitude of risks (risk analysis); and
— the process of comparing the estimated risks against risk criteria to determine the significance of the risks (risk evaluation).
Risk assessment should be performed periodically to address changes in the information security requirements and in the risk situation, for example in the assets, threats, vulnerabilitles, Impacts, the risk evaluation, and when significant changes occur. These risk assessments should be undertaken in a methodical manner capable of producing comparable and reproducible results.
The information security risk assessment should have a clearly defined scope in order to be effective and should include relationships with risk assessments in other areas, if appropriate.
ISO/IEC 27005 provides information security risk management guidance, including advice on risk assessment, risk treatment, risk acceptance, risk reporting, risk monitoring and risk review. Examples of risk assessment methodologies are included as well.
4.5.4 Treating information security risks
Before considering the treatment of a risk, the organization should define criteria for determining whether or not risks can be accepted. Risks can be accepted if, for example, it is assessed that the risk is low or that the cost of treatment is not cost-effective for the organization. Such decisions should be recorded.

ISO IEC 27000 does not apply to the process control domain of nuclear facilities. This domain is covered by IEC 62645.
ISO IEC 27000 also includes a requirenwnt to adapt the risk assessment and treatment processes described In ISO/IEC 27001:2013 to the energy utility industry-sector—specific guidance provided In this document.
Purpose: In addition to the security objectives and measures that are set forth in ISO/IEC 27002, this document provides guidelines for systems used by energy utilities and energy suppliers on information security controls which address further, special requirements.
5.5.6 Iso 27799
Health informatics — Information security management in health using ISO/IEC 27002
Scope: ISO IEC 27000 gives guidelines for organizational information security standards and information security management practices including the selection, implementation and management of controls taking into consideration the organization’s information security risk environment(s).
ISO IEC 27000 provides implementation guidance for the controls described in ISO/IEC 27002 and supplements them where necessary, so that they can be effectively used for managing health information security.
Purpose: ISO 27799 provides health organizations with an adaptation of the lSO/IEC 27002 guidelines unique to their Industry sector which are additional to the guidance provided towards fulfilling the requirements of ISO/IEC 27001:2013. Annex A.
