SECURITY METRICS
In this, we focused on metrics for measuring the success of your IT systems including infrastructure-centric metrics, Web-centric metrics, call center metrics, and financial metrics.
Another important area of metrics is security metrics, or how well you are doing at stopping viruses from coming in, protecting against identify theft, and the like.
Do some research on the Web and develop a list of commonly used metrics in the area of security. Be sure to define each metric.
