How Does ISO 27001 Work?
ISO 27001 works by providing a systematic approach for organizations to establish, implement, maintain and continually improve an Information Security Management System (ISMS). Here is an overview of how ISO 27001 works:
Scope Definition
The organization determines the scope of its ISMS, identifying the boundaries and applicability of the standard within the organization.
Risk Assessment
A risk assessment is conducted to identify and evaluate information security risks that could impact the confidentiality, integrity and availability of information assets.
Risk Treatment
Based on the results of the risk assessment, the organization selects and implements risk treatment measures to address identified risks. This may involve implementing security controls, policies, procedures or other measures.
Documentation
The organization establishes and maintains documentation related to the ISMS, including an information security policy, risk assessment reports, control objectives and other relevant documents.
Implementation and Operation
The organization implements the necessary controls and processes to address information security risks and achieve its information security objectives. This may involve training employees, implementing technical controls and monitoring security measures.
Monitoring and Measurement
The organization monitors and measures the performance of the ISMS, including the effectiveness of security controls, incidents and compliance with policies and procedures.
Internal Audit
Regular internal audits are conducted to assess the effectiveness of the ISMS, identify areas for improvement and ensure compliance with ISO 27001 requirements.
Management Review
Top management reviews the performance of the ISMS at planned intervals to ensure its continuing suitability, adequacy, effectiveness and alignment with the organization's strategic objectives.
Certification
Organizations can choose to undergo a certification audit by an accredited certification body to demonstrate compliance with ISO 27001. If the audit is successful, the organization receives ISO 27001 certification.
Continual Improvement
The organization continually improves the effectiveness of its ISMS by taking corrective actions to address non-conformities, implementing preventive actions to avoid future issues and updating the ISMS based on changes in the organization or the threat landscape.
ISO 27001 Information Security Management Principles
ISO 27001 is based on the CIA Triad, which consist of:
Confidentiality
Only the right people can access the information held by the organization.
⚠ Risk example: Criminals get hold of your clients' login details and sell them on the Darknet.
Information Integrity
Data that the organization uses to pursue its business or keeps safe for others is reliably stored and not erased or damaged.
⚠ Risk example: A staff member accidentally deletes a row in a file during processing.
Availability of Data
The organization and its clients can access the information whenever it is necessary so that business purposes and customer expectations are satisfied.
⚠ Risk example: Your enterprise database goes offline because of server problems and insufficient backup.
