ISO/IEC 27000-series

The ISO/IEC 27000-series (also known as the 'ISMS Family of Standards' or 'ISO27K' for short) comprises information security standards published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).[1]

The series provides best practice recommendations on information security management - the management of information risks through information security controls - within the context of an overall Information security management system (ISMS), similar in design to management systems for quality assurance (the ISO 9000 series), environmental protection (the ISO 14000 series) and other management systems.[2][3][4]

The series is deliberately broad in scope, covering more than just privacy, confidentiality and IT/technical/cybersecurity issues. It is applicable to organizations of all shapes and sizes. All organizations are encouraged to assess their information risks, then treat them (typically using information security controls) according to their needs, using the guidance and suggestions where relevant. Given the dynamic nature of information risk and security, the ISMS concept incorporates continuous feedback and improvement activities to respond to changes in the threats, vulnerabilities or impacts of incidents.

The standards are the product of ISO/IEC JTC1 (Joint Technical Committee 1) SC27 (Subcommittee 27), an international body that meets in person twice a year.

The ISO/IEC standards are sold directly by ISO, mostly in English, French and Chinese. Sales outlets associated with various national standards bodies also sell directly translated versions in other languages.

Early history

Many people and organisations are involved in the development and maintenance of the ISO27K standards. The first standard in this series was ISO/IEC 17799:2000; this was a fast-tracking of the existing British standard BS 7799 part 1:1999[5] The initial release of BS 7799 was based, in part, on an information security policy manual developed by the Royal Dutch/Shell Group in the late 1980s and early 1990s. In 1993, what was then the Department of Trade and Industry (United Kingdom) convened a team to review existing practice in information security, with the goal of producing a standards document. In 1995, the BSI Group published the first version of BS 7799.[6] One of the principal authors of BS 7799 recalls that, at the beginning of 1993, "The DTI decided to quickly assemble a group of industry representatives from seven different sectors: Shell ([David Lacey] and Les Riley), BOC Group (Neil Twist), BT (Dennis Willets), Marks & Spencer (Steve Jones), Midland Bank (Richard Hackworth), Nationwide (John Bowles) and Unilever (Rolf Moulton)."[7] David Lacey credits Donn B. Parker as having the "original idea of establishing a set of information security controls", and with producing a document containing a "collection of around a hundred baseline controls" by the late 1980s for "the I-4 Information Security circle[8] which he conceived and founded."

BS 7799

BS 7799 was a standard originally published by BSI Group (BSI) in 1995. It was written by the United Kingdom Government's Department of Trade and Industry (DTI), and consisted of several parts.

The first part, containing the best practices for Information Security Management, was revised in 1998; after a lengthy discussion in the worldwide standards bodies, was eventually adopted by ISO as ISO/IEC 17799, "Information Technology - Code of practice for information security management." in 2000. ISO/IEC 17799 was then revised in June 2005 and finally incorporated in the ISO 27000 series of standards as ISO/IEC 27002 in July 2007.

The second part to BS 7799 was first published by BSI in 1999, known as BS 7799 Part 2, titled "Information Security Management Systems - Specification with guidance for use." BS 7799-2 focused on how to implement an information security management system (ISMS), referring to the information security management structure and controls identified in BS 7799-2, which later became ISO/IEC 27001. The 2002 version of BS 7799-2 introduced the Plan-Do-Check-Act (PDCA) (Deming quality assurance model), aligning it with quality standards such as ISO 9000. BS 7799 Part 2 was adopted by ISO as ISO/IEC 27001 in November 2005.

BS 7799 Part 3 was published in 2005, covering risk analysis and management. It aligns with ISO/IEC 27001.

Factor analysis of information risk

Factor analysis of information risk (FAIR) is a taxonomy of the factors that contribute to risk and how they affect each other. It is primarily concerned with establishing accurate probabilities for the frequency and magnitude of data loss events. It is not a methodology for performing an enterprise (or individual) risk assessment.FAIR is also a risk management framework developed by Jack A. Jones, and it can help organizations understand, analyze, and measure information risk according to Whitman & Mattord (2013).

A number of methodologies deal with risk management in an IT environment or IT risk, related to information security management systems and standards like ISO/IEC 27000-series.

FAIR seeks to provide a foundation and framework for performing risk analyses. Much of the FAIR framework can be used to strengthen, rather than replace, existing risk analysis processes like those mentioned above. It is not another methodology to deal with risk management, but complements existing ones. It is in direct competition with the other risk assessment frameworks, if complementary to many of them.Although the basic taxonomy and methods have been made available for non-commercial use under a creative commons license, FAIR itself is proprietary. Using FAIR to analyze someone else's risk for commercial gain (e.g. through consulting or as part of a software application) requires a license from RMI.

ISO/IEC 27000

ISO/IEC 27000 is part of a growing family of ISO/IEC Information Security Management Systems (ISMS) standards, the 'ISO/IEC 27000 series'. ISO/IEC 27000 is an international standard entitled: Information technology — Security techniques — Information security management systems — Overview and vocabulary.

The standard was developed by subcommittee 27 (SC27) of the first Joint Technical Committee (JTC1) of the International Organization for Standardization and the International Electrotechnical Commission.ISO/IEC 27000 provides:

An overview of and introduction to the entire ISO/IEC 27000 family of Information Security Management Systems (ISMS) standards.

A glossary or vocabulary of fundamental terms and definitions used throughout the ISO/IEC 27000 family.ISO/IEC 27000 is available via the ITTF website. (free download)

ISO/IEC 27001

ISO/IEC 27001 is an information security standard, part of the ISO/IEC 27000 family of standards, of which the last version was published in 2013, with a few minor updates since then. It is published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) under the joint ISO and IEC subcommittee, ISO/IEC JTC 1/SC 27.ISO/IEC 27001 specifies a management system that is intended to bring information security under management control and gives specific requirements. Organizations that meet the requirements may be certified by an accredited certification body following successful completion of an audit.

ISO/IEC 27002

ISO/IEC 27002 is an information security standard published by the International Organization for Standardization (ISO) and by the International Electrotechnical Commission (IEC), titled Information technology – Security techniques – Code of practice for information security controls.

The ISO/IEC 27000-series standards are descended from a corporate security standard donated by Shell to a UK government initiative in the early 1990s

. The Shell standard was developed into British Standard BS 7799 in the mid-1990s, and was adopted as ISO/IEC 17799 in 2000. The ISO/IEC standard was revised in 2005, and renumbered ISO/IEC 27002 in 2007 to align with the other ISO/IEC 27000-series standards. It was revised again in 2013.

ISO/IEC 27002 provides best practice recommendations on information security controls for use by those responsible for initiating, implementing or maintaining information security management systems (ISMS). Information security is defined within the standard in the context of the C-I-A triad:

the preservation of confidentiality (ensuring that information is accessible only to those authorized to have access), integrity (safeguarding the accuracy and completeness of information and processing methods) and availability (ensuring that authorized users have access to information and associated assets when required).

ISO/IEC 27006

ISO/IEC 27006 is an information security standard published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Part of the ISO/IEC 27000 series of ISO/IEC Information Security Management System (ISMS) standards, it is titled Information technology - Security techniques - Requirements for bodies providing audit and certification of information security management systems.

ISO/IEC 27006 lays out formal requirements for accredited organizations which certify other organizations compliant with ISO/IEC 27001.

It effectively replaces EA 7/03 (Guidelines for the Accreditation of bodies operating certification/ registration of. Information Security Management Systems).

The standard helps ensure that ISO/IEC 27001 certificates issued by accredited organizations are meaningful and trustworthy, in other words it is a matter of assurance.

ISO/IEC 27040

ISO/IEC 27040 is part of a growing family of International Standards published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in the area of security techniques; the standard is being developed by Subcommitee 27 (SC27) - IT Security techniques of the first Joint Technical Committee 1 (JTC 1) of the ISO/IEC. A major element of SC27's program of work includes International Standards for information security management systems (ISMS), often referred to as the 'ISO/IEC 27000-series'.

The full title of ISO/IEC 27040 is Information technology — Security techniques — Storage security.

ISO/IEC 27552

ISO/IEC 27552 is a privacy extension to ISO/IEC 27001. The design goal is to enhance the existing Information Security Management System (ISMS) with additional requirements in order to establish, implement, maintain, and continually improve a Privacy Information Management System (PIMS). The draft standard outlines a framework for Personally Identifiable Information (PII) Controllers and PII Processors to manage privacy controls to reduce the risk to the privacy rights of individuals.While the standard is currently still in draft, ISO/IEC 27552 is intended to be a certifiable extension to ISO/IEC 27001 certifications. In other words, organizations planning to seek an ISO/IEC 27552 certification will also need to an ISO/IEC 27001 certification.

IT baseline protection

The IT baseline protection (in German IT-Grundschutz) approach from the German Federal Office for Information Security (FSI) is a methodology to identify and implement computer security measures in an organization. The aim is the achievement of an adequate and appropriate level of security for IT systems. To reach this goal the FSI recommends "well-proven technical, organizational, personnel, and infrastructural safeguards". Organizations and federal agencies show their systematic approach to secure their IT systems (e.g. Information Security Management System) by obtaining an ISO/IEC 27001 Certificate on the basis of IT-Grundschutz.

IT risk

Information technology risk, IT risk, IT-related risk, or cyber risk is any risk related to information technology. While information has long been appreciated as a valuable and important asset, the rise of the knowledge economy and the Digital Revolution has led to organizations becoming increasingly dependent on information, information processing and especially IT. Various events or incidents that compromise IT in some way can therefore cause adverse impacts on the organization's business processes or mission, ranging from inconsequential to catastrophic in scale.

Assessing the probability of likelihood of various types of event/incident with their predicted impacts or consequences should they occur is a common way to assess and measure IT risks. Alternative methods of measuring IT risk typically involve assessing other contributory factors such as the threats, vulnerabilities, exposures, and asset values.

IT risk management

IT risk management is the application of risk management methods to information technology in order to manage IT risk, i.e.:

The business risk associated with the use, ownership, operation, involvement, influence and adoption of IT within an enterprise or organization

IT risk management can be considered a component of a wider enterprise risk management system.

The establishment, maintenance and continuous update of an Information security management system (ISMS) provide a strong indication that a company is using a systematic approach for the identification, assessment and management of information security risks.

Different methodologies have been proposed to manage IT risks, each of them divided into processes and steps.

According to the Risk IT framework, this encompasses not only the negative impact of operations and service delivery which can bring destruction or reduction of the value of the organization, but also the benefit enabling risk associated to missing opportunities to use technology to enable or enhance business or the IT project management for aspects like overspending or late delivery with adverse business impact.[clarification needed incomprehensible sentence]

Because risk is strictly tied to uncertainty, decision theory should be applied to manage risk as a science, i.e. rationally making choices under uncertainty.

Generally speaking, risk is the product of likelihood times impact (Risk = Likelihood * Impact).

The measure of an IT risk can be determined as a product of threat, vulnerability and asset values:

A more current Risk management framework for IT Risk would be the TIK framework:

The process of risk management is an ongoing iterative process. It must be repeated indefinitely. The business environment is constantly changing and new threats and vulnerabilities emerge every day. The choice of countermeasures (controls) used to manage risks must strike a balance between productivity, cost, effectiveness of the countermeasure, and the value of the informational asset being protected.

Sarbanes–Oxley Act

The Sarbanes-Oxley Act of 2002 (Pub.L. 107–204, 116 Stat. 745, enacted July 30, 2002), also known as the "Public Company Accounting Reform and Investor Protection Act" (in the Senate) and "Corporate and Auditing Accountability, Responsibility, and Transparency Act" (in the House) and more commonly called Sarbanes–Oxley, Sarbox or SOX, is a United States federal law that set new or expanded requirements for all U.S. public company boards, management and public accounting firms. A number of provisions of the Act also apply to privately held companies, such as the willful destruction of evidence to impede a federal investigation.The bill, which contains eleven sections, was enacted as a reaction to a number of major corporate and accounting scandals, including Enron and WorldCom. The sections of the bill cover responsibilities of a public corporation's board of directors, add criminal penalties for certain misconduct, and require the Securities and Exchange Commission to create regulations to define how public corporations are to comply with the law.

Semantic service-oriented architecture

A Semantic Service Oriented Architecture (SSOA) is an architecture that allows for scalable and controlled Enterprise Application Integration solutions. SSOA describes a sophisticated approach to enterprise-scale IT infrastructure. It leverages rich, machine-interpretable descriptions of data, services, and processes to enable software agents to autonomously interact to perform critical mission functions. SSOA is technically founded on three notions:

The principles of Service-oriented architecture (SOA);

Standards Based Design (SBD); and

Semantics-based computing.SSOA combines and implements these computer science concepts into a robust, extensible architecture capable of enabling complex, powerful functions.

Standard of Good Practice for Information Security

The Standard of Good Practice for Information Security, published by the Information Security Forum (ISF), is a business-focused, practical and comprehensive guide to identifying and managing information security risks in organizations and their supply chains.

The most recent edition is 2018, an update of the 2016 edition.

Upon release, the 2011 Standard was the most significant update of the standard for four years. It covers information security 'hot topics' such as consumer devices, critical infrastructure, cybercrime attacks, office equipment, spreadsheets and databases and cloud computing.

The 2011 Standard is aligned with the requirements for an Information Security Management System (ISMS) set out in ISO/IEC 27000-series standards, and provides wider and deeper coverage of ISO/IEC 27002 control topics, as well as cloud computing, information leakage, consumer devices and security governance.

In addition to providing a tool to enable ISO 27001 certification, the 2011 Standard provides full coverage of COBIT v4 topics, and offers substantial alignment with other relevant standards and legislation such as PCI DSS and the Sarbanes Oxley Act, to enable compliance with these standards too.

The Standard is used by Chief Information Security Officers (CISOs), information security managers, business managers, IT managers, internal and external auditors, IT service providers in organizations of all sizes.

The 2018 Standard is available free of charge to members of the ISF. Non-members are able to purchase a copy of the standard directly from the ISF.
