Explanation
A security metrics dashboard is a graphical representation of key performance indicators (KPIs) and key risk indicators (KRIs) that provide useful information about the effectiveness of the information security program.
A security metrics dashboard can help communicate the value and performance of the information security program to senior management and other stakeholders, as well as identify areas for improvement and alignment with business objectives. A security metrics dashboard should be concise, relevant, timely, accurate, and actionable.
