All about the ISO/IEC 27000-series information risk and security management standards "ISO27k" refers to the ISO/IEC 27000 series standards, a set of 100 good practice guidelines for managing the risks affecting or involving information. They are listed below. "ISO/IEC" denotes the bodies that jointly developed the standards. ISO is the International Organization for Standardisation , IEC is the I nternational E lectrotechnical C ommission . Effective information risk management protects (secures) valuable information against harm whilst also permitting its use (exploitation) for business purposes. This involves systematically: Identifying risks of concern, analysing and evaluating them; Treating (avoiding, sharing, mitigating or accepting) the risks appropriately; Ensuring the risk treatments are working properly (assurance ); and Handling changes and driving continual improvement (maturity ). The standards define and comprise a ‘management system’ (governance and management arrangements) that can be adapted to suit any organisation's unique situation. Two key ISO27k standards are: ISO/IEC 27001 (I nformation S ecurity M anagement S ystem - the ISMS ); and ISO/IEC 27701 (P rivacy I nformation M anagement S ystem - the PIMS ). Other ISO27k standards expand on various aspects in more detail: ISO/IEC 27005 , for instance, elaborates on the information risk management process, while ISO/IEC 27004 offers advice on security metrics.

Back Up Next ISO/IEC 27017 ISO/IEC 27017:2015 / ITU-T X.1631 — Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services (first edition) Up Abstract “ISO/IEC 27017:2015 gives guidelines for information security controls applicable to the provision and use of cloud services by providing: additional implementation guidance for relevant controls specified in ISO/IEC 27002; additional controls with implementation guidance that specifically relate to cloud services. This Recommendation | International Standard provides controls and implementation guidance for both cloud service providers and cloud service customers.” [Source: ISO/IEC 27017:2015/ITU-T X.1631] Introduction This standard provides guidance on the information security aspects of cloud computing, recommending and assisting with the implementation of cloud-specific information security controls supplementing the guidance in ISO/IEC 27002:2013 and other ISO27k standards . Scope The 'code of practice' provides additional information security controls implementation advice beyond that provided in ISO/IEC 27002:2013 , in the context of cloud computing. Structure The standard advises both cloud service customers and cloud service providers, with the primary guidance laid out side-by-side in each clause, mirroring the structure of ISO/IEC 27002:2013 Status The current first edition was published in 2015 . Having been developed jointly by ISO/IEC and ITU-T, the standard is dual-numbered ISO/IEC 27017 and ITU-T X.1631 with identical content. Work on a second edition started in 2022. It is being updated to “capture a full set of guidance for information security controls applicable to cloud services, both from the third [2022] edition of ISO/IEC 27002 and any additional controls specific related specifically to cloud services.” ISO/IEC SC 27 and SC 38, ITU-T SG17 and the C loud S ecurity A lliance are collaborating on the revision, requiring careful scheduling to coordinate several parallel activities. Substantial changes are coming in the second edition of this standard with a complete reorganisation of the controls as per ISO/IEC 27002:2022 . The title will become “Information security, cybersecurity and privacy protection - Information security controls based on ISO/IEC 27002 for cloud services ”. It has passed a vote at F inal D raft I nternational S tandard stage, with several editorial comments that should be readily addressed. It remains on-track to for publication this year. Commentary In my opinion, ISO/IEC 27017 takes an unrealistically simplistic view of cloud service provider and customer relationships as individual one-to-one interactions. In reality, cloud services are often provided by multiple suppliers to multiple clients in different organisations, and nothing remains static for long. In practice, inter-organisational business relationships often extend through complex cloud supply chains or supply networks, with multiple parties involved in collaborating to assemble, deliver and manage cloud services (e.g . network, data centre, physical servers, virtual servers, operating systems, database management systems and other layered software, applications, and all the associated services). Consequently, there are numerous supplier-customer relationship risks to manage, such as organisational interdependence, contracting and subcontracting, complexity, dynamics and compliance. There are risk visibility and trust issues, resourcing challenges, commercial angles, technological challenges and more to contend with. Cloud-related information risks are cloudy! Risk treatments for cloud and other information risks may include risk sharing, avoidance and acceptance - not just risk mitigation using security controls. Neither this standard nor ISO/IEC 27002 pay much attention to risk treatments other than mitigation using security controls. Particularly for small or immature organisations, cloud services providing email, file storage and office apps etc . may be treated as mere commodities, procured without adequate consideration of information risk, security, privacy etc . However, some cloud services may be critical for core business, and cloud generally increases the organisation’s attack surface and vulnerabilities. [This issue may be more relevant to ISO/IEC 27005 and ISO/IEC 27036 .] Cloud services proved their value for resilience and flexible working through COVID. There are general principles and lessons here that can help organisations be better prepared to cope with future widespread/global challenges such as further pandemics, wars, Internet connectivity issues etc. Our challenge now is to draw them out, consider and embed them where appropriate - possibly in this standard. The standard has widespread support from ISO/IEC JTC 1/SC 27, ITU-T SG17, national standards bodies and CSA among others. However, aligning disparate perspectives and objectives while remaining within the defined scope of the current update project is tricky. SC 27 decided not to progress a separate cloud information security management system specification standard, judging that ISO/IEC 27001 is sufficient and given pressure from ISO not to proliferate Management Systems Standards ‘unnecessarily’. Therefore, SC 27 does not intend to develop a formal requirements specification standard against which to certify the security of cloud service providers specifically. Providers can however be certified against ISO/IEC 27001 , ISO/IEC 27701 and other standards in the usual way, while there are non-ISO cloud security assessment and certification, classification, benchmarking or assurance schemes such as CSA STAR .

Back Up Next ISO/IEC 27000 ISO/IEC 27000:2018 — Information technology — Security techniques — Information security management systems — Overview and vocabulary (fifth edition) Up Abstract “ISO/IEC 27000:2018 provides the overview of information security management systems (ISMS). It also provides terms and definitions commonly used in the ISMS family of standards. [ISO/IEC 27000] is applicable to all types and sizes of organization (e.g. commercial enterprises, government agencies, not-for-profit organizations). The terms and definitions provided in [ISO/IEC 27000]: cover commonly used terms and definitions in the ISMS family of standards; do not cover all terms and definitions applied within the ISMS family of standards; and do not limit the ISMS family of standards in defining new terms for use.” [Source: ISO/IEC 27000:2018] Introduction ISO/IEC 27000 gives an overview of I nformation S ecurity M anagement S ystems (and thus many of the ISO27k standards), plus a glossary that formally defines many (but not all) of the specialist terms as they are used within the ISMS standards. Scope ISO/IEC 27000 is focused on the 'core ISO27k standards' meaning ISO/IEC 27001 to 27008 . Other ISO27k standards are covered to a lesser extent and many are not mentioned at all (including, of course, new standards published after 2018). Structure The standard has three main clauses: 3: Terms and definitions - a glossary formally defines 77 key terms as used in various ISO27k standards . 4: I nformation S ecurity M anagement S ystems - an overview introduces information security, risk and security management, and management systems. 5: ISMS family of standards - a reasonably clear though wordy description of the ISO27k approach and some of the ISO/IEC 27000-series of standards, from the perspective of the committee that wrote them. Status The first edition was published in 2009 . It was updated in 2012 , 2014 , 2016 and 2018 . The current 2018 fifth edition is available legitimately from ISO for free . This was a minor revision of the 2016 fourth edition with a section on abbreviations, and a rationalisation of the metrics-related definitions following the 2016 rewrite of ISO/IEC 27004 . The sixth edition of ISO/IEC 27000 is a work-in-progress. In accordance with ISO directives, the current edition’s vocabulary will be moved to an annex containing a “definition and explanation of commonly used terms in the ISO/IEC 27000 family of standards” - more specifically, the glossary will apply to ISO27k standards belonging to ISO/IEC JTC 1/SC 27/WG 1 (ISO/IEC 27001 to ISO/IEC 27011 , ISO/IEC 27013 , ISO/IEC 27014 , ISO/IEC 27016 , ISO/IEC 27017 , ISO/IEC 27019 , ISO/IEC 27021 to ISO/IEC 27024 , ISO/IEC 27028 and ISO/IEC 27029 ). Terms will be grouped conceptually in the annex rather than alphabetically. However, various specialist terms used in ISO/IEC 27000 itself are to be defined in clause 3 as usual. The new sixth edition will be a lot shorter, halving the page count. Publication of the sixth edition is due this year. It has passed a vote at F inal D raft I nternational S tandard stage, with just a few minor comments. The title is to become “Information security, cybersecurity and privacy protection — Information security management systems — Overview” . Commentary Clause 4 “Concepts and principles”, new to the sixth edition is intended to clarify the fundamentals underpinning information risk and security management. The information security controls in ISO/IEC 27001 Annex A , 27002 , 27010 , 27011 , 27017 and 27019 are to be termed “Candidate necessary information security controls ” - a curious and ambiguous turn of phrase reflecting the committee’s persistent difference of opinion in this area. ‘Necessary’ is for the organisation to determine according to its evaluation of information risks relative to its risk appetite. ‘Candidate’ is clearly not ‘required’ and is less than ‘suggested’, but still some readers and inept auditors may feel the controls have to be implemented by default: they don't. Given the chance, I would replace “information security risk” throughout the ISO27k standards with the shorter, simpler and more appropriate term “information risk”. “Information security risk” is not formally defined as a complete phrase and doesn’t even make sense: it is presumably trying to indicate that we are talking about risk in the context of information security, but it could be interpreted as “risk to information security” which I guess would including things such as failing to identify novel risks, and lack of management support for the function: those are indeed risks, but they are not the focus of ISO27k. “Information risk”, in contrast, is reasonably self-evident but, if the committee feels the desperate need for an explicit definition, I suggest something as simple as “risk relating to or involving information” or even “risk pertaining to information”, where both risk and information are adequately defined in dictionaries (whereas the current ISO27k definition of risk is unhelpful). Thus far, I have failed to persuade the committee to accept this terminological change, which admittedly would ripple through most of the ISO27k standards. However, the sixth edition's clause 4.1.2 is expected to include the following concerning 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.” OK, yes it deserves adequate protection, but it also deserves legitimate exploitation for business purposes. That duality is something that management should address systematically using the ISMS as a framework. “It does not matter whether the information is owned by the organization or is entrusted to its care by a third party, e.g., a customer.” Patently ownership of information does matter, so that statement is plain wrong. Protection and exploitation of information matter to the owners of both business/commercial/proprietary and personal information (including that belonging to employees, by the way). Even public-domain information can be of value to society, groups or individuals, while inaccurate, outdated, incomplete, misleading, coercive, manipulative or malicious information is of concern regardless of who owns it. I suspect that second sentence was supposed to build upon the first but somehow the linkage has been lost in translation, with unintended consequences. Pressing ahead: “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 information in the form of knowledge. Information can be transmitted by various means including courier, electronic or verbal communication. Whatever form information takes, or how it is transmitted, it always needs appropriate protection.” All good so far, but then ... “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.” The final paragraph reveals the longstanding systemic bias towards technology (more specifically, I nformation T echnology as opposed to, say, Operational, Communications or Smart Technologies) throughout the ISO27k standards. While clearly it is true that information security controls based on technology play a large part in protecting digital data, technology alone will never completely replace the need for humans to protect information as well, including the use of physical and organisational controls (such as policies, contracts and assurance measures). And, last but not least, the controls are specified, designed, used and managed by humans, while security incidents affect humans. In short, it’s humans all the way down .

Back Up Next ISO/IEC 27014 ISO/IEC 27014:2020 / ITU-T X.1054 — Information security, cybersecurity and privacy protection — Governance of information security (second edition) Up Abstract ISO/IEC 27014 "provides guidance on concepts, objectives and processes for the governance of information security, by which organisations can evaluate, direct, monitor and communicate the information security-related processes within the organisation. The intended audience for [ISO/IEC 27014] is: governing body and top management; those who are responsible for evaluating, directing and monitoring an information security management system (ISMS) based on ISO/IEC 27001; those responsible for information security management that takes place outside the scope of an ISMS based on ISO/IEC 27001, but within the scope of governance. [ISO/IEC 27014] is applicable to all types and sizes of organisations. All references to an ISMS in [ISO/IEC 27014] apply to an ISMS based on ISO/IEC 27001. [ISO/IEC 27014] focuses on the three types of ISMS organisations given in Annex B. However, [ISO/IEC 27014] can also be used by other types of organisations.” [Source: ISO/IEC 27014:2020/ITU-T X.1054] Introduction This standard, produced by ISO/IEC JTC 1/SC 27 in collaboration with the I nternational T elecommunications U nion’s T elecommunication Standardization Sector (ITU-T), is specifically aimed at helping organisations govern their information security arrangements . Scope ISO/IEC 27014 “provides guidance on concepts, objectives and processes for the governance of information security, by which organisations can evaluate, direct, monitor and communicate the information security-related processes within the organisation.” In a nutshell, through sound governance arrangements, information security management achieves business objectives - a very important and powerful concept. As with other ISO27k standards , it is “applicable to all types and sizes of organisations”, particularly those with one or more ISO 27001 -style ISMSs encompassing either the entirety or certain parts of the organisation, or where a single ISMS applies across several businesses or business units (e.g . within a group structure). Structure Main clauses: 6: Governance and management standards e.g. ISO/IEC 27001 and 38500. 7: Entity governance and information security governance - 6 objectives and 4 processes 8: The governing body’s requirements on the ISMS Annex A: Governance relationship Annex B: Types of ISMS organization - e.g. multiple or shared ISMSs in group structures Annex C: Examples of communication - a couple of situations where information security governance may need to be disclosed The standard explains four “processes” (key aspects of governance): Evaluation: senior management considers proposals and plans for information security management (e.g. "We will adopt an ISO27001 ISMS"); Direction: preparing strategies, policies and objectives for information security that align with and support the achievement of the organisation’s business objectives (e.g. “It is imperative that we both protect and exploit valuable information”); Monitoring the performance of information security through management information flows and internal reporting arrangements (e.g. “We track the following security metrics: ...”); Communication: ensures that all those within the organisation who are actively involved in directing, overseeing, driving, guiding and monitoring information security are 'singing from the same hymn sheet', while external stakeholders (such as its owners and regulatory authorities) are assured that information risk is being competently managed. It also lays out six information security objectives that the governance and management arrangements should satisfy: Establish integrated comprehensive entity-wide information security since the information at risk exists and is legitimately exploited, and hence deserves protection, throughout the organisation; Make decisions using a risk-based approach - fundamental to all the ISO27k standards and at all levels of the ISMS from governance and strategy through management to routine operations (e.g . risk-assessing identified incidents to determine the priority and nature of the responses required); Set the direction of acquisition - as in corporate mergers and acquisitions, as opposed to procuring goods and services; Ensure conformance with internal and external requirements through assurance such as auditing of information security activities; Foster a security-positive culture - an excellent suggestion, albeit easier said than done; Ensure the security performance meets current and future requirements of the entity - there is a need for suitable management oversight, monitoring and measurement (metrics) in relation to current requirements, of course, but what about the future ? Food for thought here. Status The first edition was published jointly by ISO/IEC and ITU-T in 2013 , dual-numbered as ISO/IEC 27014 and ITU-T recommendation X.1054 with identical text. The second edition was published by ISO/IEC in 2020 and then separately by ITU-T, released as X.1054 (04/2-21) - a free PDF download in 2021. In conjunction with ITU-T, it seems work is under way in 2026 on a third edition - a minor editorial revision, updating references to cited standards and swapping the order of appendices A and B. Commentary ISO/IEC 27014 refers to ‘information risk management ’ - a minor but important distinction from the usual terms ‘information security risk’ and ‘information security management’. Security (as in controls to reduce/mitigate risk) is not the only way to treat risks to information: they can also be avoided, shared and accepted. Personally, I wish the remaining ISO27k standards would adopt ‘information risk’ (defined along the lines of “risk pertaining to information”) in place of ‘information security risk’ (a term that is not actually defined as such) but, so far, SC 27 management has blocked the move and we have not had the opportunity to debate it. I am merely a lone, weak and tiring kayaker gently nudging ISO’s supertanker. In the course of drafting the second edition, SC 27 discussed the application of principles from ISO 38500 (“Corporate governance of IT”) to information security, and considered the relationship between information security governance and other governance and management disciplines. ISO/IEC 27014 refers to governance for information security as an integral part of the organisation’s corporate governance with strong links to IT governance, but is arguably a bit vague on the details. The definition of ‘governing body’ obliquely notes that, along with ‘executive management’, both are parts of ‘top management’ which ISO/IEC 27000 defines as “the person or group of people who directs and controls an organisation at the highest level”. In essence, the standard hints that senior managers can have distinct or separable governance (strategic direction-setting) and hands-on executive management roles. The summary points out that the standard “provides the mandate essential for driving information security initiatives throughout the organisation.” At present, this is typically achieved in part by senior management mandating an overarching organisation-wide information security policy that is supported and amplified by lower level security policies, standards, procedures, guidelines and other security awareness materials. The standard does not go into depth on other related aspects such as the information security, risk and compliance management structures, reporting lines, divisions of responsibility, delegated authorities and so forth, largely I guess because of the differences between organisations. As an information security professional with a keen interest in security awareness , I am gratified to note that, in order to “establish a positive information security culture, the governing body should require, promote and support coordination of stakeholder activities to achieve a coherent direction for information security. This will support the delivery of security education, training and awareness programs.” ‘A coherent direction’ indeed. Nice idea. I approve. ISO 37000:2021 “Guidance for the governance of organisations” could be the basis for updating ISO/IEC 27014 to utilise common concepts and terms. Maybe. At some point.

Back Up Next ISO/IEC 27045 ISO/IEC 27045 — Information technology — Big data security and privacy — Guidelines for managing big data risks [DRAFT] Up Abstract ISO/IEC 27045 "provides guidance on how to navigate the threats that can arise during the big data life cycle from the various big data characteristics that are unique to big data: volume, velocity, variety, variability, volatility, veracity and value, including when using big data for the design and implementation of AI systems. [ISO/IEC 27045] can help organizations build or enhance their big data security and privacy capabilities, including when using big data in the development and use of AI systems.” [Source: ISO/IEC JTC 1/SC 27 Committee Doc 11 May 2025] Introduction ‘Big data’ systems present numerous information security, privacy and technological challenges due to complexity plus the sheer quantity and volatility of the data. Scope The standard is intended to help organisations build or enhance their information security and privacy capabilities relating to big data systems, perhaps as part of AI systems design and implementation. Structure Main clauses: 4: Overview - a brief summary. 5: Big data - explores the information risk and security implications of big data in addition to the 'traditional' concerns for conventional IT systems. Describes the seven v's. 6: Security and privacy threats and controls to big data - stepping through the seven 'v ' characteristics of big data (v olume, v elocity, v ariety, v ariability, v olatility, v eracity and v alue), identifying pertinent threats and controls. 7: Big data risk management process - builds on the guidance in ISO/IEC 27005 . Annex A: maps the organisational and technological controls from clause 6 against the threats relating to the seven v's. Annex B: use cases . Status This standard was initially proposed in 2017. Having run off-the-rails in 2021, the drafting project re-started in 2024. It is currently at F inal D raft I nternational S tandard stage and (if approved) may be published towards the end of 2026 or early 2027. Commentary The definition of ‘big data’ quoted from ISO/IEC 20456:2019 does not (in my personal, rather jaundiced/cynical opinion) reflect its widespread use in the IT industry at present. “Extensive datasets primarily in the characteristics of volume, variety, velocity, and/or variability that require a scalable architecture for efficient storage, manipulation, and analysis ”. I prefer Wikipedia ’s description: “Current usage of the term big data tends to refer to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set. "There is little doubt that the quantities of data now available are indeed large, but that's not the most relevant characteristic of this new data ecosystem." Analysis of data sets can find new correlations to "spot business trends, prevent diseases, combat crime and so on." Scientists, business executives, practitioners of medicine, advertising and governments alike regularly meet difficulties with large data-sets in areas including Internet searches, fintech, urban informatics, and business informatics. Scientists encounter limitations in e-Science work, including meteorology, genomics, connectomics, complex physics simulations, biology and environmental research.” It seems to me a defining characteristic is that big data is (are!) so big that conventional database management systems are unable to cope with the complexity and dynamics/volatility, struggling to maintain integrity given so many coincident changes. Beyond the limits of their scalability, conventional architectures start to experience constraints and failures (including security control and privacy issues), no matter how much raw CPU power, network bandwidth and storage capacity is thrown at the challenge. That implies the need for fundamentally different approaches with novel information risks most likely requiring novel controls. It remains to be seen what this standard will actually recommend: this is cutting-edge stuff. Hopefully this standard will refer to others for the low-level and relatively conventional data security and privacy controls that apply to small and medium data, focusing instead on the high-level and novel aspects and processes that are unique to big data e.g. : Strategic management of big data sets, big data systems etc. , including governance arrangements to monitor and control the management and operational activities as a whole (e.g. overall programme as well as individual project management) and the business/strategy aspects and requirements (e.g. enormous financial investment in huge systems implies enormous expected returns); Architecture and design of big data systems - specifically the data security and privacy aspects including information risk assessment, compliance, ethics, data aggregation, inference, interconnectivity (both within and without the organisation), access controls, metadata management and security, resilience etc. ; Operation and use of big data systems e.g . how to classify and segregate data and functions, how to determine/define and assign access rights/permissions, what privacy and security roles and responsibilities might be appropriate; Maintenance and support of big data systems, including their security and privacy aspects; Capacity and performance management including the dynamics and challenges arising; Incident management, change management and so on (adapting conventional processes for the big data environment). Potentially, the standard could get into advanced/novel data/system security controls and privacy approaches involving artificial intelligence, instrumentation, anomaly and fraud detection, automated responses etc. ... but it looks as if the standard’s initial release will be more modest.

Back Up Next ISO/IEC TS 27008 ISO/IEC TS 27008:2019 — Information technology — Security techniques — Guidelines for the assessment of information security controls (second edition) Up Abstract ISO/IEC TS 27008 "provides guidance on reviewing and assessing the implementation and operation of information security controls, including the technical assessment of information system controls, in compliance with an organisation's established information security requirements including technical compliance against assessment criteria based on the information security requirements established by the organisation. [ISO/IEC TS 27008] offers guidance on how to review and assess information security controls being managed through an Information Security Management System specified by ISO/IEC 27001. It is applicable to all types and sizes of organisations, including public and private companies, government entities, and not-for-profit organisations conducting information security reviews and technical compliance checks.” [Source: ISO/IEC TS 27008:2019] Introduction This standard (a T echnical S pecification) on “technical auditing” complements ISO/IEC 27007 . It is focused on auditing the information security controls (or rather the “technical controls”, which although undefined evidently means IT security or cybersecurity controls). In contrast, ISO/IEC 27007 is more concerned with the management system . Scope ISO/IEC TS 27008 provides guidance for all auditors/assessors regarding “information security management systems controls” [sic ] selected through a risk-based approach (e.g . as presented in a S tatement o f A pplicability) for information security management. It supports the information risk management process and internal, external and third-party audits of an ISMS by explaining the relationship between the ISMS and its supporting controls. It provides guidance on how to verify the extent to which the organisation’s "necessary ISMS controls” satisfy its control objectives. Furthermore, it supports any organisation using ISO/IEC 27001 and ISO/IEC 27002 to satisfy assurance requirements, and as a strategic platform for the governance and management of information risk and security. Structure Main clauses: 5: Background 6: Overview of information security control assessments 7: Review methods 8: Control assessment process Annex A: Initial information gathering (other than IT) Annex B: Practice guide for technical security assessments Annex C:Technical assessment guide for cloud services (Infrastructure as a Service) With over 100 pages, this is a substantial standard. Status The first edition was published in 2011 as ISO/IEC TR 27008:2011, a Type 2 T echnical R eport. It set out to provide “Guidelines for auditors on information security controls”. The current second edition was published in 2019 as ISO/IEC TS 27008:2019, a T echnical S pecification reflecting the 2013 versions of ISO/IEC 27001 and ISO/IEC 27002 . The title morphed into “Guidelines for the assessment of information security controls”, dropping the explicit reference to auditing. The third edition is in preparation, being revised to reflect ISO/IEC 27002:2022 . It will revert to a T echnical R eport. It is at D raft T echnical R eport stage, likely to emerge during 2026. Commentary ISO/IEC TS 27008 gives technology auditors background knowledge to help them review and evaluate the information security controls being managed through an I nformation S ecurity M anagement S ystem - or indeed any other structured governance approach (e.g. NIST's C yber S ecurity F ramework, or GDPR and NIS2 from Europe). The current second edition: Is applicable to organisations of all types and sizes; Supports planning and execution of ISMS audits and the information risk management process; Further adds value and enhances the quality and benefit of the ISO27k standards by closing the gap between reviewing the ISMS in theory and, when needed, verifying evidence of implemented ISMS controls (e.g . in the ISO27k user organisations, assessing security elements of business processes, IT systems and IT operating environments); Provides guidance for auditing information security controls based on the controls guidance in ISO/IEC 27002:2013 ; Improves ISMS audits by optimizing the relationships between the ISMS processes and required controls (e.g. mechanisms to limit the harm caused by failures in the protection of information - erroneous financial statements, incorrect documents issued by an organisation and intangibles such as reputation and image of the organisation and privacy, skills and experience of people); Supports an ISMS-based assurance and information security governance approach and audit thereof [?? That strays from the standard’s scope into the area of management systems auditing]; Supports effective and efficient use of audit resources, including the enhancement of technology auditors' skills, competence and knowledge. Whereas ISO/IEC 27007 focuses on auditing the management system elements of an ISMS as described in ISO/IEC 27001 , ISO/IEC TS 27008 focuses on checking the information security controls themselves, such as (for example) those as in Annex A of ISO/IEC 27001 . ISO/IEC TS 27008 “focuses on reviews of information security controls, including checking of technical compliance, against an information security implementation standard, which is established by the organisation. It does not intend to provide any specific guidance on compliance checking regarding measurement, risk assessment or audit of an ISMS as specified in ISO/IEC 27004 , ISO/IEC 27005 or ISO/IEC 27007 respectively.” 'Technical compliance checking/auditing' is explained as a process of examining ‘technical’ security controls, interviewing those associated with the controls (managers, technicians, users etc. ) and testing the controls. The methods should be familiar to experienced technology auditors. ‘Technical’ controls, while not explicitly defined in the standard, appear to be what are commonly known as IT security, cybersecurity or technological controls, in other words a subset of the information security controls listed in ISO/IEC 27001 Annex A and described in ISO/IEC 27002 . Furthermore, the correct term here is conformity, not compliance, since it is discretionary. But I digress. Liberal use of “technical” in phrases such as “technical compliance checking of information system controls”, “technical assessment” and “technical security controls”, indicates that this standard is concerned with technology , implying IT or data or cyber security, specifically, rather than information risk and security in general. While this standard is not intended to be used for certification, it remains inconsistent and ambiguous (frankly, unclear and confusing) in the use of key terms such as: review, assessment, test, validation, check and audit. For example, are “information security auditors” the same as “certification auditors”, “IT auditors”, “internal auditors”, “ISMS internal auditors”, “compliance auditors”, “conformity auditors”, or something else? There are no (zero) definitions in the second edition since all terms are supposedly defined in ISO/IEC 27000 : concerning that little list of terms, only “audit”, “information security” and “conformity” are defined, separately. “Risk assessment” is specifically defined but not “assessment” in general. So, conventional dictionary definitions presumably apply ... but don’t really help. For an international standard, it could hardly be more muddled. Up Up Up This page last updated: 11 February 2026

Back Up Next ISO/IEC 27033-5 ISO/IEC 27033-5:2013 Information technology — Security techniques — Network security — Part 5: Securing communications across networks using Virtual Private Networks (VPNs) (first edition) Up Abstract ISO/IEC 27033 part 5 “gives guidelines for the selection, implementation, and monitoring of the technical controls necessary to provide network security using Virtual Private Network (VPN) connections to interconnect networks and connect remote users to networks.” [Source: ISO/IEC 27033-5:2013] Introduction ISO/IEC 27033-5 revised ISO/IEC 18028 part 5. It extends the IT security management guidelines of ISO/IEC TR 13335 by detailing the specific operations and mechanisms needed to implement network security safeguards and controls in a wider range of network environments, providing a bridge between general IT security management issues and network security technical implementations. It provides guidance for securing remote access over public networks. Scope The standard guides network administrators and technicians who plan to make use of this kind of connection, or who already have it in use and need advice on how to set it up securely and operate it securely. Structure Main clauses: 6: Overview 7: Security threats 8: Security requirements 9: Security controls 10: Design techniques 11: Guidelines for product selection Status ISO/IEC 27033-5 revised and replaced ISO/IEC 18028-5 . The current first edition of part 5 was published in 2013 and confirmed unchanged in 2019 and again in 2025. Commentary Gives a high-level, incomplete assessment of the threats to VPNs i.e. it mentions the threats of intrusion and denial of service ... but not unauthorized monitoring/interception, traffic analysis, data corruption, insertion of bogus traffic, various attacks on VPN end points, malware, masquerading/identity theft, insider threats etc ., although these are mentioned or at least hinted-at later under security requirements. Introduces different types of remote access including protocols, authentication issues and support when setting up remote access securely. Up Up Up This page last updated: 23 February 2026

Back Up Next ISO/IEC 27553-2 ISO/IEC 27553-2:2025 — Information security, cybersecurity and privacy protection — Security and privacy requirements for authentication using biometrics on mobile devices — Part 2: remote modes (first edition) Up Abstract ISO/IEC 27553 part 2 "provides high-level security and privacy requirements for authentication using biometrics on mobile devices, in particular, for functional components, communication, storage and remote processing. [The standard] is applicable to remote modes, i.e. the cases where: the biometric sample is captured through mobile devices, and the biometric data or derived biometric data are transmitted between the mobile devices and the remote services in either or both directions. The following are out of scope of this document: the cases where the biometric data or derived biometric data never leave the mobile devices (i.e. local modes), the preliminary steps for biometric enrolment before authentication procedure, and the use of biometric identification as part of the authentication.” [Source: ISO/IEC 27553-2:2025 ] Introduction Part 2 provides high-level requirements for situations where biometric authentication on mobile devices involves communicating biometric data over the network to a remote authentication server. Scope Biometric authentication on mobile devices where biometric information is communicated between the devices and remote services via network connections, as opposed to local modes where the authentication process and data are limited to the devices. The standard is restricted to authentication, excluding enrolment and identification. Structure Main clauses: 5: Security and privacy considerations 6: System description 7: Information assets 8: Threat analysis 9: Security requirements and recommendations 10: Privacy considerations, requirements and recommendations Annex A: Implementation example Annex B: Authentication assurance and assurance level Status The current first edition was published in 2025 . Commentary Involvement of remote services in the authentication process implies network data communication with associated confidentiality, integrity and availability implications, as well as risks relating to the remote storage and processing (such as aggregating, correlating and comparing biometric and other data between various remote and networked systems to glean additional information). Not being a S ubject M atter E xpert in authentication, specifically, I am intrigued by obscure terms such as “synthesized wolf biometric samples” and “hill climbing attack”. Presumably these are covered by the numerous cited standards and familiar to authentication SMEs. It would be challenging to adopt ISO’s version of plain English for such a technical standard.
