ISO IEC 27001 International Standard covers all types of organizations (e.g. commercial enterprises, government agencies, non-profit organizations). This International Standard specifies the requirements for establishing, implementing, operating, monitoring, reviewing, maintaining and improving a documented ISMS within the context of the organization’s overall business risks. It specifies requirements for the implementation of security controls customized to the needs of individual organizations or parts thereof. The ISMS is designed to ensure the selection of adequate and proportionate security controls that protect information assets and give confidence to interested parties.
Benefit of ISO/IEC 27001 implementation
ISO/IEC 27001:2005 is intended to be suitable for several different types of use, including the following:
- use within organizations to formulate security requirements and objectives;
- use within organizations as a way to ensure that security risks are cost effectively managed;
- use within organizations to ensure compliance with laws and regulations;
- use within an organization as a process framework for the implementation and management of controls to ensure that the specific security objectives of an organization are met;
- definition of new information security management processes;
- identification and clarification of existing information security management processes;
- use by the management of organizations to determine the status of information security management activities;
- use by the internal and external auditors of organizations to determine the degree of compliance with the policies, directives and standards adopted by an organization;
- use by organizations to provide relevant information about information security policies, directives, standards and procedures to trading partners and other organizations with whom they interact for operational or commercial reasons;
- implementation of business-enabling information security;
- use by organizations to provide relevant information about information security to customers.
Audit ISO IEC 27001
The ISO/IEC 27001 certification, like other ISO management system certifications, usually involves a three-stage audit process:
- Stage 1 is a “table top” review of the existence and completeness of key documentation such as the organization’s security policy, Statement of Applicability (SoA) and Risk Treatment Plan (RTP).
- Stage 2 is a detailed, in-depth audit involving testing the existence and effectiveness of the information security controls stated in the SoA and RTP, as well as their supporting documentation.
- Stage 3 is a follow-up reassessment audit to confirm that a previously-certified organization remains in compliance with the standard. Certification maintenance involves periodic reviews and re-assessments to confirm that the ISMS continues to operate as specified and intended.
