It’s important to remember that ISO 27001’s full title is “ISO/IEC 27001 – Information technology — Security approaches — Information security management systems — Requirements.”
It is the main worldwide information security standard produced by ISO and the IEC. Both are significant international standards bodies.
The ISO/IEC 27000 family of information security standards includes ISO-27001.
ISO Framework And ISO 27001’s Purpose
The ISO framework is a set of policies and procedures for usage by organizations. Through the adoption of an Information Security Management System, ISO 27001 provides enterprises of any size and in any industry with a framework for protecting their information in a methodical and cost-effective manner (ISMS).
Why Is ISO 27001 Valuable?
The standard not only teaches companies how to protect their most sensitive data, but it also allows them to become ISO 27001-certified and show clients and partners that they do.
Take a course and pass an exam to get ISO 27001 Certification in Australia and show potential employers your expertise.
ISO 27001 is a global standard, that increases businesses’ commercial potential.
How Does ISO 27001 Work?
ISO 27001’s main goal is to protect a company’s information. The risk assessment determines what data issues could arise and what must be done to prevent them.
Thus, ISO 27001’s basic principle is risk management: identify dangers and then build security measures to mitigate them.
What Are ISO 27001’s Fourteen Domains?
ISO 27001 defines fourteen “domains” in sections A.5–A.18 of Annex A. The subjects are:
A.5. Information security policies: The controls in this section show how to manage information security rules.
A.6. Organization of information security: The controls in this section define the internal organization and organizational components of information security, which cons/titute the foundation for its implementation and operation.
A.7. Human resource security: The controls in this part ensure that employees under the business’s control are hired, trained, and managed securely. Discipline and agreement termination are also covered.
A.8. Asset management: This section ensures that information security assets are identified, that responsibilities for their protection are assigned, and that employees know how to handle them based on predetermined classification levels.
A.9. Access control: This section limits data and data asset access based on business needs. There are physical and logical access controls.
A.10. Cryptography: This section’s controls lay the groundwork for using encryption to protect information’s confidentiality, authenticity, and integrity.
A.11. This section prohibits illegal entry and protects equipment and facilities from human and natural action.
A.12. Operations security: This section’s controls secure and prevent data loss in IT systems such as operating systems and software. This part’s controls also require the tools to record events and give proof, periodic vulnerability verification, and precautions to avoid audit activities interfering with company operations.
A.13. Communications security: These rules protect network infrastructure, services, and data.
A.14. System acquisition, development, and maintenance: This section’s controls ensure that information security is considered while acquiring new information systems or upgrading existing ones.
A.15. Supplier relationships: These measures ensure that suppliers and partners’ outsourced operations use suitable information security controls and explain how to monitor third-party security performance.
A.16. Information security incident management: The rules in this section provide a framework for ensuring the proper communication and handling of security events and incidents so they can be effectively addressed and resolved quickly. They also define how to preserve evidence and learn from incidents to prevent their recurrence.
A.17. Information security in business continuity management Information security management and system availability are maintained by this section’s controls.
A.18. Compliance: This section’s controls prevent legal, legislative, regulatory, and contractual infractions and audit whether information security has been implemented and is effective according to ISO 27001’s principles and procedures..
