Explanation:
A security policy is a general statement to define management objectives with respect to security. The security strategy addresses higher level issues. Guidelines are optional actions and operational tasks. A security baseline is a set of minimum requirements that is acceptable to an organization.

The ratio of false positives to false negatives will indicate whether an intrusion detection system (IDS) is properly tuned to minimize the number of false alarms while, at the same time, minimizing the number of omissions. The number of attacks detected, successful attacks or the ratio of successful to unsuccessful attacks would not indicate whether the IDS is properly configured.
