Information Security Management System (ISMS) – ISO 27001

Information Security Management System (ISMS) is a management system based on a systematic business risk approach, to establish, implement, operate, monitor, review, maintain, and improve information security. It is an organizational approach to information security. ISO/IEC 27001 is a standard for information security that focuses on an organization’s ISMS.

Objective of ISMS

    Information security is the protection of information to ensure:

• Confidentiality: ensuring that the information is accessible only to those authorised to access it.
• Integrity: ensuring that the information is accurate and complete and that the information is not modified without authorization.
• Availability: ensuring that the information is accessible to authorized users when required.

Why should I implement ISO 27001 ISMS?

• Certification of a management system brings several advantages. It gives an independent assessment of your organization’s conformity to an international standard that contains best practices from experts for ISMS.
• Meeting legislative and regulatory requirements
• As a measure and independent evidence that industry best practices are being followed.
• As part of a corporate governance program
