EXCEL APPLICATION: Citywide Community College The IT Department at Citywide Community College developed a computer security incident response plan that requires users to provide information every time a security incident occurs. The IT managers inventoried the major components of the college's computer systems and created a spreadsheet to track the equipment by manufacturer, model number, and serial number. They decided to confine the list to major computer components, and they do not try to track keyboards, mice, and so forth. The managers then created a spreadsheet to track systems security incident facts including information about the department reporting the incident, target-specific information (host machine name, etc.), source-specific information (source IP address), and information about the type of security incident or attack. Assignment The IT managers have asked you to use the data provided in the CCC Security spreadsheet, Ch1OExO1, to identify (1) the department reporting the highest number of security incidents and (2) the most prevalent type of intrusion. Use the "countif" function to count the number of security incidents in which the computer system was compromised. Use a memo format to submit a summary of your findings to the IT department.
