Question 42 (10 points) Suppose 950 benign and 50 malicious events in a certain time interval (i.e., 1,000 events in total). The recent evaluation report for the newly developed intrusion detection system (IDS) shows that 45 malicious events were detected by the IDS, but the IDS was unable to identify the other five malicious events. Also, the IDS wrongly classified 10 benign events into intrusions. a. (opt.) Complete the confusion matrix based on the IDS evaluation report. Intrusion Attack No Intrusion Attack Alarm Sounded No Alarm Sounded b. (4pt.) Calculate the accuracy, precision, false positive rate, and false negative rate of the IDS using formulas we have studied in our lecture. Show all steps.
