you are the information security manager for the county of Islington. The county just elected a new sheriff. He does not have a keen understanding of what is Physical Security. It is your responsibility as the security manager to brief the sheriff on what is physical security and how it can be used to protect critical technological infrastructures throughout the county.  Please provide a PowerPoint Presentation with no less than 15 informative slides. Further, you will use Zoom to record yourself, giving the presentation, and explaining the slides. You do not have to be in the video. The slides must include pictures and other graphics showing the technological infrastructures in the county as well as supporting the presentation. The presentation should address the following.  What is physical security? What are the levels of physical security?      Detail all five levels on separate slides What is the value of planning as it relates to the levels of physical security? What are physical barriers and how they coincide with physical security? Explain security or master plan and countermeasures Expound on designing security and layout of the site  

Mini Case: Campus BikesIn Chapter 6 (Please see hw 5 description), you learned that Campus Bikes is a popular bicycle shop located near a major university. The shop sells several brands of new bikes, including everything from high-end racing models to beach cruisers. In addition to sales of new bikes and accessories, Mark’s service department is always busy. The staff includes Mark himself, a bookkeeper, two part-time sales reps, a full-time mechanic, and several part-time service helpers who assemble bikes.BackgroundUntil now, the owner, Mark Turner, kept the business records on his personal computer. He cre- ated a simple database to keep track of inventory, but it is not always up-to-date. He also developed spreadsheets to track expenses and payroll. The business has grown and Mark wants to install a new computer system to handle all business functions.You are a lab assistant in the computer information department at the college. You earneda computer science degree at a two-year school, and you recently decided to work toward your four-year degree. Mark recently asked you to help him plan a system for Campus Bikes. You used an object-oriented approach to create a model of the business functions and actors involved.Now Mark wants you to do a “make or buy” analysis. Specifically, you will look into the pros and cons of in-house development versus purchase of a software package. Your research indicates that the most popular bike shop package is offered by a vendor called BikeData.In your last meeting, Mark said that tangible savings for a new system would be hard to measure, but improved customer care, better service department records, and increased productivity are expected. Mark estimates that these benefits will add up to about $3,000 per year, whether the system is developed in-house, or purchased from BikeData.You decide to compare relative costs to establish a total cost of ownership (TOC) over the use- ful life of the system. Based on your research, you put together the following summary:Costs for Option A: Develop In-houseThe system will have a six-year useful life, be very flexible, and easiest to maintain.It will cost $15,000 to develop, install, and configure the system, and $1,000 to load existing data.Mark and the bookkeeper can handle day-to-day support with no added expense. Costs for Option B: Purchase BikeData Software PackageThis is a vertical package with a four-year useful life.The software is less flexible than an in-house system and some customizing will be needed.It will cost $8,000 to purchase, $1,500 to install and configure, $2,500 to load existing data, and $1,000 additional hardware will be neededSupport is free for the first year, then there is a $2,000 annual fee Benefits for Both Options: $3,000 per yearTasks(30 pts) Prepare a detailed list of pros and cons of in-house versus software purchase.(20 pts) Calculate ROI for both options.(20 pts) Calculate NPV for both options.
