What is your most unforgettable memory?

When and where did it happen?

Who were with you during that time?

Why is this memory special to you?

How did this experience change or inspire you?

Learning Goal: I’m working on a computer science project and need the explanation and answer to help me learn.

Overview:

Exploring Analytics Tools and Their Impact on Data Science

In Chapter 9, we explore the growing diversity of software tools and languages available to data scientists, highlighting the importance of selecting the right tool for the task. The chapter covers both open-source and commercial analytics tools, the rise of workflow-based tools like KNIME and Orange, and the increasing adoption of Python and R for data analysis. It also emphasizes the importance of understanding the strengths and limitations of these tools, as well as their accessibility and scalability in real-world applications.

Discussion Prompt:

With the plethora of analytics tools and platforms available today, how do you decide which one to use for a given data science project? Discuss the key factors that influence this decision, including the project requirements, team expertise, cost considerations, and the need for scalability or real-time processing. Additionally, how do open-source tools like Python and R compare with commercial tools in terms of accessibility, functionality, and support?

Post Instructions:

Create a short video demonstrating how to perform a basic data analysis task using both a commercial tool (e.g., SAS or Tableau) and an open-source tool (e.g., Python or R). Highlight the differences in ease of use, capabilities, and the learning curve associated with each tool. Discuss when one might be preferred over the other based on the project needs.

Assignment 1: Cyber ThreatRiskAttack Landscape Survey

Weight: 20%

Assessment Type: Survey

Format: Individual Assignment

Description:

In this assignment, you are required to research and analyze and conduct in-depth survey of the current cyber threatriskattack landscape, exploring the evolving nature of cybersecurity challenges faced by organizations today. You need to focus on cyber threat landscape from a global, GCC and UAE perspective that

changes both over time and has significant impact on the organization and the internetworked users (IU).

The objective is to examine and critically assess how risks, threats, and attacks interrelate, and how they shape business vulnerabilities in various industries and what organizations are doing to protect themselves.

You are expected to:

Part A: Identify at least 10 real-world examples of cyber incidents from recent years, analyze their causes and impacts, and evaluate the broader trends these cases reveal. The analysis should include specific discussion of:

Risk: The potential for loss or damage to assets, systems, or data.

Threat: The actors, vectors, and conditions that could exploit vulnerabilities.

Attack: Specific incidents or actions taken to compromise confidentiality, integrity, or availability.

Identify and analyze the emergence and discovery of threats and the associated vulnerabilities that

provide cybercriminals with new attack opportunities (pre covid and post covid).

Part B: Review and comment on current best practices and strategies organizations employ for risk mitigation, including frameworks, technologies, and governance approaches. Identify the global events such as the COVID-19 pandemic compelling organizations to make major changes to their IT infrastructure.

Deliverable:

A comprehensive written report (~2,000 words) that:

(Use this report template)

1. Explains the relationship between risk, threat, and attack in the cybersecurity context.
2. Provides at least three detailed case studies from recent real-world incidents.
3. Identifies patterns and trends in the current cyber landscape.
4. Discusses the effectiveness of current industry/business best practices for risk mitigation.

Assignment Evaluation Criteria:

Depth and clarity of analysis.

Relevance and credibility of cited examples.

Integration of theory with real-world evidence.

Critical evaluation of mitigation strategies.

Report structure, writing quality, and citation of sources (APA format).

I need these three done.

There are two steps to the assessment!!!

Step 1.Take the Big Five Personality Test by clicking the link. It takes most people 3-8 minutes:

1. Click “Link” above to begin assessment.

2. On new page click “Begin Assessment” button to start.

3. Select an answer for each of the 50 questions. After you answer a new question will appear.

4. If you have difficulty answering a question, you can skip forward. Or, if you want to change an answer you can go back. There is also a numerical counter to let you know how many questions you have answered out of the 50 total, so 8/50 means you on question 8.

5. When you get to the end of the assessment, select “No” and click the “Continue” button.

Step 6. Take a screenshot that shows the graph with score percentile and save it as a .jpg, .png, or .pdf.

Example:
