1)  Here is my Data:

Christopher Vigliotti
	Employee has run a computer security scan in the past 60 days.	Employee has NOT run a computer security scan in the past 60 days.	Total
Employee has installed the latest patches to the operating system on their computer.	86	45	131
Employee has NOT installed the latest patches to the operating system on their computer.	355	14	369
Total	441	59	500

2)  P (Has NOT run security scan) = 59/500 = 0.118 = 11.8%

     P (Has NOT installed the latest patches) = 369/500 = 0.738 = 73.8%

     P (Has NOT installed the latest patches but has run security scan) = 355/500 = 0.71 = 71%

     P (Has installed the latest patches but has NOT run security scan) = 45/500 = 0.09 = 9%

3)  Based on the analysis of this sample of employees, i would say that the likelihood of a computer breach is high.  Almost 75% of the employees have not installed the latest patches to their systems.  Coming from my cybersecurity classes, this is one of the #1 contributors to security incidents such as data breaches.  The latest patches include security fixes for issues found in the time since the last patches have been released.  Another thing that can be interpreted from the data is that they company and employees are very good about running security scans.  This will help the security situation, but without the proper patches to fix the security holes, our company is ripe for a data breach.

1. Here is my data:

	Employee has run a computer security scan in the past 60 days.	Employee has NOT run a computer security scan in the past 60 days.	Total
Employee has installed the latest patches to the operating system on their computer.	33	382	415
Employee has NOT installed the latest patches to the operating system on their computer.	18	67	85
Total	51	449	500

 

2. P (has NOT run security scan) = 449/500 = 0.898 = 89.8%

P (has NOT installed latest patches) = 85/500 = 0.17 = 17%

P (has NOT installed the latest patches but has run security scan) = 18/500 = 0.036 = 3.6%

P (has installed the latest patches but has NOT run security scan) = 382/500 = 0.764 = 76.4%

Based on an analysis of my sample of 500 employees, I would say that the likelihood of a computer breach is moderate going into high. You can see that over 75% of the employees have NOT run a security scan. The number one method to prevent security breaches is to regularly perform security scans, which makes those numbers concerning. Furthermore, you can see that only less than 20% of the employees HAVEN’T installed the latest patches of the operating system, which means that more than 75% HAVE installed the latest patches to the operating system. This too contributes greatly towards a security breach and action should be taken to fix this.
