Project Deliverable 4: Infrastructure and SecurityDue Week 8 and worth 150 pointsThis assignment consists of two (2) sections: an infrastructure document and a revised Gantt chart or project plan. You must submit both sections as separate files for the completion of this assignment. Label each file name according to the section of the assignment for which it is written. Additionally, you may create and / or assume all necessary assumptions needed for the completion of this assignment.The last section of the project plan will present the infrastructure in accordance with the parameters set forth at the outset of the project. The network solution that is chosen should support the conceived information system and allow for scalability. The network infrastructure will support organizational operations; therefore, a pictorial view of workstations, servers, routers, bridges, gateways, and access points should be used. In addition, access paths for Internet access should be depicted. A narrative should be included to explain all the nodes of the network and the rationale for the design. Lastly, using the Confidentiality, Integrity and Availability (CIA) Triangle, define the organizational security policy. CIA is a widely used benchmark for evaluation of information systems security.Section 1: Infrastructure Document1. Write a five to ten (5-10) page infrastructure document in which you:a. Design a logical and physical topographical layout of the planned network through the use of graphical tools in Microsoft Word or Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length.b. Illustrate the possible placement of servers including access paths to the Internet and firewalls. Note: Facility limitations, workstations, printers, routers, switches, bridges and access points should be considered in the illustration.c. Explain the rationale for the logical and physical topographical layout of the planned network.d. Create a comprehensive security policy for the company that will:i. Protect the company infrastructure and assets by applying the principals of CIA. Note: CIA is a widely used benchmark for evaluation of information systems security, focusing on the three core goals of confidentiality, integrity and availability of information.ii. Address ethical aspects related to employee behavior, contractors, password usage, and access to networked resources and information.Your assignment must follow these formatting requirements:This course requires use of Strayer Writing Standards (SWS).
