Show your calculations in an Excel or Google Sheets spreadsheet and upload. Suppose that two different network firewall software applications are being tested by a new small business. Two firewalls were tested, A and B. Suppose that over one month of time, the below types of spyware/malware were passed through onto the network by these firewalls. Answer the following questions. Key Loggers Cookies Hijackers Trojan HorsesFirewall A 4 184 0 2Firewall B 4 166 2 5What percentage of all spyware/malware in this test was not captured by A. Of the hijackers, what percentage were allowed by Firewall B. If I chose a security issue at random, what is the probability that it was either a key logger or trojan horse. If I chose a security issue at random, and given that it was not blocked by B, what is the probability that the issue not blocked by B was a cookie.
