Book excerpt: This bookdefines more than 900 metrics measuring compliance with current legislation, resiliency of security controls, and return on investment. It explains what needs to be measured, why and how to measure it, and how to tie security and privacy metrics to business goals and objectives. The metrics are scaled by information sensitivity, asset criticality, and risk; aligned to correspond with different lateral and hierarchical functions; designed with flexible measurement boundaries; and can be implemented individually or in combination. The text includes numerous examples and sample reports and stresses a complete assessment by evaluating physical, personnel, IT, and operational security controls.
