One qualitative and the other quantitative—3 pages each for a total of 6. Find two peer-reviewed articles, one qualitative research, and the other quantitative research in the field of cybersecurity/computer science and do a review on them. The article review should have an intro/background that provides context for the research article, methodology, how data was gathered/analyzed, what research question and statistical analysis used study findings/limitation, and the conclusion. The conclusion should evaluate article significance, research methods, readability, and implications. Does further study needed? What are the strengths and weaknesses of the article in terms of statistical analysis and application? Articles to be reviewed MUST be peer-reviewed, in cybersecurity/IT/computer science field.

The project python source code as described above: calculator.py 2. A documentation report: Create an MS Word file called final.docx which contains the specific section titles listed below. • TITLE: Include your name, your class section, and the project title. • PROGRAM DOCUMENTATION: This section should include a brief description of how to run your program (i.e., what the user should type and any other information a user might need to know) and also a brief description that might be used by another programmer to modify/extend your program. For example, there may be some features that you would have included in your program if you had more time. You could include a list of those features and your thoughts on how they should be implemented. • TEST Cases: List at least five (5) test cases that your program handles to demonstrate the project functionality. Do not assume you have a smart user. Test also for wrong user entry. • REFLECTIONS: Include at least a one-paragraph description of what you learned from this project. It might help to think about what problems you encountered, and what you would do differently if you had to do another project. 3. A 10-slide MS Power Point Presentation: You will present your project in the virtual classroom. This is an opportunity to show off your hard work! The presentation may include elements from the report and should be organized as follows: ? Slide 1: Title ? Slide 2: Introduction ? Slide 3: Goal and purpose of the Project ? Slide 3: Input/Process/Output details (IPO chart can be included) ? Slide 4: Project Development Process ? Slide 6: Project Testing/Maintenance ?

(#1) In 1987, Denning wrote that the development of a real-time intrusion-detection system is motivated by four factors: 1) most existing systems have security flaws that render them susceptible to intrusions, penetrations, and other forms of abuse; finding and fixing all these deficiencies is not feasible for technical and economic reasons; 2) existing systems with known flaws are not easily replaced by systems that are more secure-mainly because the systems have attractive features that are missing in the more- secure systems, or else they cannot be replaced for economic reasons; 3) developing systems that are absolutely secure is extremely difficult, if not generally impossible; and 4) even the most secure systems are vulnerable to abuses by insiders who misuse their privileges. ****** Are these factors still relevant today? Are there any new factors that motivate the development of real-time intrusion-detection systems. Justify your answer. [50 pts] – Article is included as a .PDF for reference and use.******* (#2) ******* In your own words explain the concept of Network Security Monitoring (NSM).
