PART ONE

**Instructions**

Several tools exist that can be used by cybersecurity professionals in identifying and removing malware. For this task, imagine that an organization with which you are familiar has recently been experiencing malware attacks from various external sources. Internal tools have failed to identify and mitigate the attacks. Assume that you are the chief cyber security officer, and you recommended to the CISO to allow the use of cloud-based tools in detecting and mitigating the attacks. The CISO asked that you present to the board of directors and provide a vivid analysis of cloud-based tools used in the prevention and removal of malware.

Address the following in your paper:

- A brief description of why cloud-based tools are the only solution you recommend.
- A paragraph each that describes three cloud-based tools used in the identification and mitigation of malware.
- Recommend a cloud-based tool that your organization can use for analysis and removal of malware.

Length: 2-3 pages, not including titles and reference pages.

References: Support your paper with a minimum of 3 scholarly resources

**Keep your audience in mind**. Remember you are not preparing this for an academic audience. Your audience will not care about theoretical or conceptual issues in information systems security. They will only care about specific issues, strategies, and scenarios that are relevant to their organization.

Your paper should demonstrate thoughtful consideration of the ideas and concepts that are presented in the course and provide new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards.

PART TWO

Mathematical Models and Risk Management

**Instructions**

A mathematical mode presents a general description of a computer system or collection of systems. In cybersecurity, a mathematical model may provide a definition of “protect” and conditions under which the protection is provided. With a mathematical model, the conditions can be shown to provide the stated protection and high degree of assurance of protection if the model is implemented correctly. Two common mathematical models in cybersecurity are one that determines under what conditions one can prove types of systems secure and the other that describes how the computer system applies controls.

For this task, write a paper on mathematical model and cybersecurity. Address the following in your paper:

- Describe the uses of mathematical models in cybersecurity.
- Describe the implementation of the mathematical model in information security.
- Access-control matrix model
- Typed access control model
- Mandatory access control model
- Discretionary access control model
- Role-based access control model
- Bell-LaPadula Model
- Biba Integrity Model
- Clark-Wilson Model
- Chinese wall Model

- Contrast the mathematical models described above.
- Describe the application of the models in different security postures.

Length: 5-7 pages, not including titles and reference pages.
