ISO IEC 27000

ISO/IEC 27000 Overview & Glossary Recommended Reading

Data breaches are one of the most serious threats to an organisation’s information security. Sensitive data seeps through almost every business process these days.

Every month, thousands of incidents occur, where, for example, cyber attackers break into a database or workers lose or misappropriate details. Wherever the data is stored, the financial and reputational consequences of a breach can be serious. As a result, businesses are gradually putting resources into their safeguards, with ISO 27001 serving as a checklist for effective security. ISO 27001 is applicable to organisations of any scale and across any industry, and the framework’s scope ensures that its implementation is often proportionate to the size of the organisation.

What is the ISO 27000 series of standards?

The ISO/IEC 27000 family of standards, also known as the ISMS family of standards or, more simply, ISO27K, cover a broad range of information security standards published by both the International organisation for Standardisation and International Electrotechnical Commission. ISO 27000 recommends best practices—best practices for managing information risks by implementing security controls—within the framework of an overall Information Security Management System (ISMS).

It is very similar to standard management systems such as those for quality assurance and environmental protection. ISO/IEC purposely broadened the scope of the ISO 27000 series so it covers security, privacy and IT issues as well. organisations of all shapes and sizes can benefit from it.

The information security controls should be tailored to the needs of each organisation so that they can treat the risks as they deem appropriate.

Organisations should rely on security guidance and suggestions when appropriate. As information security and risk management are dynamic disciplines, the ISMS concept incorporates continuous feedback and improvements to respond to the changes in threats or vulnerabilities that occurred as a result of incidents. Information security experts suggest that compliance with the ISO 27000 series is the first step toward an information security program that will properly protect your organisation.

The standards, however, are not specific to any industry and this makes them able to be applied in any business, regardless of size and industry. Standardisation is a product of ISO/IEC JTC1 SC27, an international body that meets formally twice a year.

History of the ISO 27000 series of standards

Numerous individuals and organisations support the development and maintenance of the ISO27K standards.

ISO/IEC 17799:2000 was the first standard of this series; it was a fast-track revision of the current British standard BS 7799 part 1:1999. The initial publication of BS 7799 was based in part on an information security management framework developed by the Royal Dutch/Shell Group.

In 1993, the United Kingdom’s then Department of Trade and Industry commissioned a committee to conduct a survey of current information technology practices with the intention of creating a standard guide. The BSI Group released the first edition of BS 7799 in 1995.

The first portion of BS 7799, which dealt with information technology best practices, was integrated into ISO 17799 and was added to the ISO 27000 list in 2000.

The second section, titled “Information Security Management Systems – Specification and Guidance for Use,” became ISO 27001 and covered the introduction of an information security management system.

Just like the ISO 9000 series, which is known for quality, ISO 27000 is an optional certification that can be used to demonstrate that an organisation has a certain degree of information security awareness.

Published ISO 27000 standards

ISO has officially designated the ISO 27000 set of standards for information security purposes. This, of course, corresponds to a host of other standards, including ISO 9000 (quality management) and ISO 14000 (environmental management).

Why Implement ISO 27000-Series Standard?

Following the ISO 27000 series standards has a host of beneficial advantages. To begin, it enables an organisation to safeguard mission-critical data while also safeguarding employee and customer information.

This will help instil greater confidence in your operations among customers and staff, significantly enhancing your image and hopefully mitigating any negative impact on your audience’s perception of your trustworthiness. ISO 27000 certification is the kind of initiative that provides an outstanding return on investment, manifesting itself both in boosting public perception of the brand and in the internal organisation of the company. In all scenarios, the advantages lead to reduced costs and a stronger market position.

This is particularly apparent in businesses that must comply with data security, confidentiality, and information technology governance standards, such as those in the finance industry or healthcare.

After all, ISO 27000 will provide methodologies for more effective information security management. It is important to note that, while the ISO 27000 set of standards is well-defined, it is a dynamic document that can be revised as new technology and challenges emerge.

By following these new standards and ensuring that you are still up to date with ISO 27000, regardless of the market in which you operate, you will always protect your organisation’s most confidential data and foster trust among customers and employees.

ISO 27000 certification process

Obtaining ISO 27000 certification does not have to be difficult or costly. It will need time, commitment, and the help of the senior management (s). Additionally, you must pay attention to detail and maintain correct paperwork and forms. The following are common steps to ISO implementation and certification.

  1. Get senior management onboard

    The senior manager(s) must be the driving force behind the decision to introduce ISO 27000 and must encourage it at every stage.

  2. Define the Scope of Implementation

    The implementation scope, as well as organisational and functional boundaries, should be specified.

  3. Documentation

    As with ISO 9000, ISO 27000 requires extensive documentation to ensure that all relevant millstones and administrative, technological, and physical controls/safeguards are addressed. These documentations may be used to determine whether the company complies with the provisions of ISO 27000. These manuals will include a policy (or collection of policies) and any accompanying written protocols and instructions to ensure the business complies with ISO specifications efficiently and effectively.

  4. GAP Analysis

    By using Gap Analysis, comparing real results to the desired success, and documenting, it is possible to ensure that the organisation is adhering to all policies and procedures. This pre-assessment is necessary to ensure that the company is headed in the right direction. Pre-assessment may be accomplished by the use of pre-assessment formats, the collection of evidence, and the completion of checklists.

  5. Audit

    Certification audit requires the assistance of an experienced (or certified) internal or external auditor. For this task, audit tools such as forms and checklists are needed.

  6. Certification

    A third-party certification body will conduct an audit and determine that your ISMS process is in line with the ISO 27000 standards. Once this checks out, the body will grant the certificate on your behalf. Certificates are usually valid for three years.

  7. Maintaining the Certification

    To keep the ISMS functional, the organisation should incorporate it into everyday activities. Additionally, continuous development and progress management are critical components of this evolving phase.

Which companies can be ISO 27000 certified?

Organisations of all sizes and industries can implement procedures and techniques to achieve ISO 27000 certification.

Regardless of size or industry, there is that sense of accomplishment associated with ISO 27000 implementation and certification.

Certification establishes confidence and fosters a positive picture of credibility. Additionally, ISO 27000 is highly compliant with ISO 9000, enhancing the efficiency and security of internal processes.
