23、 to evaluate the information security performance and the effectiveness of an information security management system in order to fulfil the requirements of ISO/IEC 27001:2013, 9.1: monitoring, measurement, analysis and evaluation. The results of monitoring and measurement of an information security

24、management system (ISMS) can be supportive of decisions relating to ISMS governance, management, operational effectiveness and continual improvement. As with other ISO/IEC 27000 documents, this document should be considered, interpreted and adapted to suit each organizations specific situation. The

25、concepts and approaches are intended to be broadly applicable but the particular measures that any particular organization requires depend on contextual factors (such as its size, sector, maturity, information security risks, compliance obligations and management style) that vary widely in practice.

26、 This document is recommended for organizations implementing an ISMS that meets the requirements of ISO/IEC 27001. However, it does not establish any new requirements for ISMS which conform to ISO/IEC 27001 or impose any obligations upon organizations to observe the guidelines presented. ISO/IEC 201

The results of analysis are evaluated in fulfilment of the organizations information needs. In addition, Annex A describes a measureme

35、nt model for information security, including the relationship between the components of the measurement model and the requirements of ISO/IEC 27001:2013, 9.1. Annex B provides a wide range of examples. These examples are intended to provide practical guidance on how organizations can monitor, measur

36、e, analyse and evaluate their chosen ISMS processes and areas of information security performance. These examples use the suggested template given in Table 1. Annex C provides a further example using an alternative free-form text-based format. Figure 1 Mapping to ISO/IEC 27001:2013, 9.1 requirements

37、 5 Rationale 5.1 The need for measurement The overall objective of an ISMS is the preservation of confidentiality, integrity and availability of information within its scope. There are ISMS activities that concern the planning of how to do this, and the implementation of those plans. However, by the

38、mselves, these activities cannot guarantee that the realisation of those plans fulfil the information security objectives. Therefore, in the ISMS as defined by ISO/IEC 27001, there are several requirements to evaluate if the plans and activities ensure the fulfilment of the information security obje

39、ctives.2 ISO/IEC 2016 All rights reservedBS ISO/IEC 27004:2016ISO/IEC 27004:2016(E) 5.2 F ulfilling the ISO/I E C 27001 r equir ements ISO/IEC 27001:2013, 9.1 requires the organization to evaluate the information security performance and the effectiveness of the ISMS. Measure types able to fulfil th

40、ese requirements can be found in Clause 7. ISO/IEC 27001:2013, 9.1 further requires the organization to determine: a) what needs to be monitored and measured, including information security processes and controls; b) the methods for monitoring, measurement, analysis and evaluation, as applicable, to

41、 ensure valid results; c) when the monitoring and measuring shall be performed; d) who shall monitor and measure; e) when the results from monitoring and measurement shall be analysed and evaluated; and f) who shall analyse and evaluate these results. The mapping of these requirements is provided in

42、 Figure 1. Finally, ISO/IEC 27001:2013, 9.1 requires the organization to retain appropriate documented information as evidence of the monitoring and measurement results (See 8.9). ISO/IEC 27001:2013, 9.1 also notes that methods selected should produce comparable and reproducible results in order for

43、 them to be considered valid (See 6.4). 5.3 Validity of results ISO/IEC 27001:2013, 9.1 b) requires that organizations choose methods for measurement, monitoring, analysis and evaluation to ensure valid results. The clause notes that to be valid, results should be comparable and reproducible. To ach

44、ieve this, organizations should collect, analyse, and report measures, taking the following points into consideration: a) in order to get comparable results on measures that are based on monitoring at different points in times, it is important to ensure that scope and context of the ISMS are not cha

45、nged; b) changes in the methods or techniques used for measuring and monitoring do not generally lead to comparable results. In order to retain comparability, specific tests such as parallel application of the original as well as the changed methods can be required; c) if subjective elements are par

46、t of the methods or techniques used for measuring and monitoring, specific steps can be needed to obtain reproducible results. As an example, questionnaire results should be evaluated against defined criteria; and d) in some situations, reproducibility can only be given in specific circumstances. Fo

47、r example, there are situations where results are non-reproducible, but are valid when aggregated. 5.4 Benefits Fulfilling ISMS processes and controls and ensuring information security performance can provide a number of organizational and financial benefits. Major benefits can include: a) Increased

48、 accountability: Monitoring, measurement, analysis and evaluation can increase accountability for information security by helping to identify specific information security processes or controls that are implemented incorrectly, are not implemented, or are ineffective. b) Improved information securit

49、y performance and ISMS processes: Monitoring, measurement, analysis and evaluation can enable organizations to quantify improvements in securing information ISO/IEC 2016 All rights reserved 3BS ISO/IEC 27004:2016ISO/IEC 27004:2016(E) within the scope of their ISMS and demonstrate quantifiable progress in accomplishing the organizations information security objectives. c) Evidence of meeting requirements: Monitoring, measurement, analysis and evaluation can provide documented
