Problem 2. Below is a depiction of the probability density functions of an IDS. The overlapping area of the two probability density functions represents the region in which there is the potential for false positives and false negatives. Suppose there is 1 actual intrusion for every 1000 authorized users, and the overlapping area covers 1% of the authorized users and 50% of the intruders. What is the probability that an event that occurs in this region is that of an authorized user? Is this IDS designed well? Event distribution prole of authorized user behavior overlap in observed or expected behavmr prole of intruder behavior Measurable behavior parameter
