Assessing effectiveness of security measures

The organization conducts internal audits in accordance with its internal audit procedure. The aim is to check:

• whether the information security management system complies with the organisation's cyber security requirements
• whether the information security management system complies with other operational security requirements or standards complied with
• whether the information security management system is implemented effectively

Documented information on the execution and results of audits must be kept.

The ISMS should monitor the implementation of the tasks and guidelines recorded therein.

The task owner should regularly review the implementation status of the ISMS as a whole.

The organisation regularly evaluates the level of cyber security and the effectiveness of the information security management system.

Organisation has defined:

• monitored metrics to provide comparable results on the development of cyber security level
• persons responsible for the metering
• methods, timetable and responsible persons for metrics reviewing and evaluation
• methods to document metric-related evaluations and results

Effective metrics should be usable for identifying weaknesses, targeting resources better and assessing organisation's success / failure related to cyber security.

Top management shall review the organization's information security management system at planned intervals to ensure that it remains appropriate, relevant and effective.

The management review shall address and comment on at least the following:

• Status of improvements (or other actions) initiated as a result of previous management reviews
• Future changes relevant to the security management system
• Performance of the ISMS (problem areas, metering, audit results and fulfillment of management security objectives)
• Stakeholder feedback on data security
• Operation of the risk assessment and treatment process

Documented information on the execution and results of reviews must be maintained.

Organisation carries out data security auditing regularly. Auditing is used to identify e.g. problems and development needs in data systems and system providers activity.

Important auditing partners should be listed on Other stakeholders -list.

The idea behind the certification mechanisms is to demonstrate that data processing follows good data processing practices and good practices in general. Example of a security certificate is for example: ISO27001.

The effectiveness of cyber security training is regularly evaluated. The evaluation may include e.g. the following perspectives:

• Is the competence of the staff deep enough?
• Are the training methods and amounts correct?
• Are different units trained in the right things?
• Is the staff motivated to learn?
• Does the staff understand the reasons for the training (e.g. what kind of negative effects can a cyber security breach have?
