An Information Security Management System (ISMS) involves implementing and maintaining processes to efficiently manage the protection of information and, in doing so, ensuring its integrity, confidentiality and availability. You may implement guidelines set out in ISO 27001, COBIT, NIST or in any other similar framework or you may even create your own management system. What matters in order to make ISMS efficient is to consider all these factors of the cycle.

MONITORAND MEASURE
Check the measures in place for
correct functioning, in addition to
measuring the success of manage
ment against parameters set in
advance.
• Security audits

MAINTAINAND IMPROVE
Once the obtained results are verified
and measured, improvements – which
are to be planned, set in motion, and
reviewed – must be fed back into the
process.
• Treatment of non-conformities:
address non-compliance
• Corrective actions for permanent
improvement
