need a short paper of 3 - 4 pages on information assurance

Research one countermeasure or information security service that is available today for information assurance. Evaluate it based on the specifications and reviews. Identify who would use this particular countermeasure or service and why it would be appropriate for their needs. Illustrate this using an example of an online activity (e.g., banking, shopping) that could use this countermeasure. Create a visual representation in MS Visio of the activity to include in your short paper. Provide a short description of the visual representation, identifying the various information assets and the information states that pose vulnerability. How would the countermeasure that you identified apply? What vulnerability would it mitigate? What are its limitations?
