The Cyber Metric Library is a list of security metrics that can be used as a baseline for any executive reporting platform. The list is not exhaustive, and is focussed primarily on technical controls that can be measured easily with available tooling.
Having some form of automated security reporting platform will help organisations to have real-time visibility of the security posture across their environment. By tailoring the dashboards to different audiences (or personas), CISOs and CIOs can leverage data for decision-making, giving visibility to all levels within the organisation.
