ISO/IEC 2. 70. 02 code of practice. Please support our sponsors .. ISO/IEC 2. 70. 02 traces its history back more than 3. BS 7. 79. 9. Scope of the standard.
Like governance and risk management, information security management is a broad topic with ramifications throughout all organizations. Information security, and hence ISO/IEC 2. The specific information risk and control requirements may differ in detail but there is a lot of common ground, for instance most organizations need to address the information risks relating to their employees plus contractors, consultants and the external suppliers of information services. The standard is explicitly concerned with information security, meaning the security of all forms of information (e. It uses ISO/IEC 2. ISMS, but since ISO/IEC 2. ISO/IEC 2. 70. 01 incorporates a summary (little more than the section titles in fact) of controls from ISO/IEC 2. Annex A. In practice, most organizations that adopt ISO/IEC 2. ISO/IEC 2. 70. 02. Structure and format of ISO/IEC 2. ISO/IEC 2. 70. 02 is a code of practice - a generic, advisory document, not a formal specification such as ISO/IEC 2. It recommends information security controls addressing information security control objectives arising from risks to the confidentiality, integrity and availability of information. Organizations that adopt ISO/IEC 2. The standard is structured logically around groups of related security controls. Many controls could have been put in several sections but, to avoid duplication and conflict, they were arbitrarily assigned to one and, in some cases, cross- referenced from elsewhere. For example, a card- access- control system for, say, a computer room or archive/vault is both an access control and a physical control that involves technology plus the associated management/administration and usage procedures and policies. This has resulted in a few oddities (such as section 6. It may not be perfect but it is good enough. Contents of ISO/IEC 2. In more detail, here is a breakdown summarizing the standard’s 1.

ISO 27001 Information Security SOP, Risk Sample and Policy covers guideline for standard operating procedures, risk control technique process and information security. ISO 27001 is a standard. Foreword. Briefly mentions ISO/IEC JTC1/SC 2. ISO/IEC 2. 70. 02: 2. Section 0: Introduction. This lays out the background, mentions three origins of information security requirements, notes that the standard offers generic and potentially incomplete guidance that should be interpreted in the organization’s context, mentions information and information system lifecycles, and points to ISO/IEC 2. ISO2. 7k. Section 1: Scope. The standard gives recommendations for those who are responsible for selecting, implementing and managing information security. It may or may not be used in support of an ISMS specified in ISO/IEC 2. Section 2: Normative references. ISO/IEC 2. 70. 00 is the only standard considered absolutely indispensable for the use of ISO/IEC 2. However, various other standards are mentioned in the standard, and there is a bibliography. Section 3: Terms and definitions. All the specialist terms and definitions are now defined in ISO/IEC 2. ISO2. 7k family of standards. Section 4: Structure of this standard. Security control clauses. Of the 2. 1 sections or chapters of the standard, 1. There is a standard structure within each control clause: one or more first- level subsections, each one stating a control objective, and each control objective being supported in turn by one or more stated controls, each control followed by the associated implementation guidance and, in some cases, additional explanatory notes. The amount of detail is responsible for the standard being nearly 9. A4 pages in length. ISO/IEC 2. 70. 02 specifies some 3. The control objectives are at a fairly high level and, in effect, comprise a generic functional requirements specification for an organization’s information security management architecture. Few professionals would seriously dispute the validity of the control objectives, or, to put that another way, it would be difficult to argue that an organization need not satisfy the stated control objectives in general. However, some control objectives are not applicable in every case and their generic wording is unlikely to reflect the precise requirements of every organization, especially given the very wide range of organizations and industries to which the standard applies. However, the headline figure is somewhat misleading since the implementation guidance recommends numerous actual controls in the details. The control objective relating to the relatively simple sub- subsection 9. Secure log- on procedures”, for instance, is supported by choosing, implementing and using suitable authentication techniques, not disclosing sensitive information at log- on time, data entry validation, protection against brute- force attacks, logging, not transmitting passwords in clear over the network, session inactivity timeouts, and access time restrictions. Whether you consider that to be one or several controls is up to you. It could be argued that ISO/IEC 2. Furthermore, the wording throughout the standard clearly states or implies that this is not a totally comprehensive set. An organization may have slightly different or completely novel information security control objectives, requiring other controls (sometimes known as . At the top level, there should be an overall “information security policy” as specified in ISO/IEC 2. Section 6: Organization of information security. Internal organization. The organization should lay out the roles and responsibilities for information security, and allocate them to individuals. Where relevant, duties should be segregated across roles and individuals to avoid conflicts of interest and prevent inappropriate activities. There should be contacts with relevant external authorities (such as CERTs and special interest groups) on information security matters. Information security should be an integral part of the management of all types of project. Mobile devices and teleworking. There should be security policies and controls for mobile devices (such as laptops, tablet PCs, wearable ICT devices, smartphones, USB gadgets and other Boys Toys) and teleworking (such as telecommuting, working- from home, road- warriors, and remote/virtual workplaces). A formal disciplinary process is necessary to handle information security incidents allegedly caused by workers. Termination and change of employment. Security aspects of a person’s departure from the organization, or significant changes of roles within it, should be managed, such as returning corporate information and equipment in their possession, updating their access rights, and reminding them of their ongoing obligations under privacy and intellectual property laws, contractual terms etc. Network access and connections should be restricted. User access management. The allocation of access rights to users should be controlled from initial user registration through to removal of access rights when no longer required, including special restrictions for privileged access rights and the management of passwords (now called “secret authentication information”) plus regular reviews and updates of access rights. User responsibilities. Users should be made aware of their responsibilities towards maintaining effective access controls e. System and application access control. Information access should be restricted in accordance with the access control policy e. Specialist advice should be sought regarding protection against fires, floods, earthquakes, bombs etc. Equipment “Equipment” (meaning ICT equipment, mostly) plus supporting utilities (such as power and air conditioning) and cabling should be secured and maintained. Equipment and information should not be taken off- site unless authorized, and must be adequately protected both on and off- site. Information must be destroyed prior to storage media being disposed of or re- used. Unattended equipment must be secured and there should be a clear desk and clear screen policy. Section 1. 2: Operations security. Operational procedures and responsibilities. IT operating responsibilities and procedures should be documented. Changes to IT facilities and systems should be controlled. Capacity and performance should be managed. Development, test and operational systems should be separated. Protection from malware. Malware controls are required, including user awareness. Backup. Appropriate backups should be taken and retained in accordance with a backup policy. Logging and monitoring. System user and administrator/operator activities, exceptions, faults and information security events should be logged and protected. Clocks should be synchronized. Control of operational software. Software installation on operational systems should be controlled. Technical vulnerability management Technical vulnerabilities should be patched, and there should be rules in place governing software installation by users. Information systems audit considerations. IT audits should be planned and controlled to minimize adverse effects on production systems, or inappropriate data access. Communications security 1. Network security management. Networks and network services should be secured, for example by segregation. Information transfer. There should be policies, procedures and agreements (e. Changes to systems (both applications and operating systems) should be controlled. Software packages should ideally not be modified, and secure system engineering principles should be followed. The development environment should be secured, and outsourced development should be controlled. System security should be tested and acceptance criteria defined to include security aspects. Note: there is a typo in 1. See the status update below, or technical corrigendum 2 for the official correction. Test data Test data should be carefully selected/generated and controlled. Supplier relationships 1. Information security in supplier relationships. There should be policies, procedures, awareness etc. Service changes should be controlled.
