Performance of the Current ICT Infrastructure - Server Network Infrastructure - IT - Computer Science Assignment Help

Assignment Task :

Scenario

This assignment is research based; you should extensively use resources such as the Internet, Library books, Technology Journals, etc.

Assignment Tasks summary:

Use the provided Network Upgrade Investigation template, and fill in each section as indicated in detail under each Task on the following pages.

1. Research an existing ICT Infrastructure - preferably your place of work, or a place where you have recently worked or done work experience. Ideally, the network should not be too large, and even a small peer-to-peer network is suitable for this assignment.  
   Essential: You need to have enough knowledge of the existing network to enable you to make recommendations for a suitable upgrade.
   If you have never worked on a local area network, another option is to get details of a friend’s workplace network, or a friend’s small business network.
   You can make assumptions - document all assumptions in the Appendix, under Assumptions Made.
   Introduce the reader to the selected ICT Infrastructure as described in the assignment below.

2. Carry out an Evaluation and Performance Evaluation of the selected ICT Infrastructure by examining each network device’s performance as described in the assignment below. (If you no longer have access to this network, you can make up these details based on your previous experience with this network.)

3. Design a complete new Server Network Infrastructure Design by applying the lessons learned while completing tasks in Testout labs and activities.

4. Produce a Server Security Baseline to be applied to all or selected servers in the new / proposed ICT Infrastructure design.

5. Create the ICT Infrastructure Monitoring section by discussing how you to plan to monitor the performance and security of the ICT Infrastructure that you designed in above task 3 and 4.

6. Create the ICT Infrastructure Support section by describing all human resources roles required to maintain and support the ICT Infrastructure and its users.

7. Create Appendix A – Assumptions Made by listing and describing all assumptions made.

8. Create the Bibliography of all referenced material.

Tasks

Task 1 Introduction of the Selected ICT Infrastructure

1. Introduce the reader to the selected company/business and describe its nature of being, i.e. what does the company do, how it operates, etc.

2. Describe the company’s current ICT Infrastructure, your discussion as minimum should include the following:

• WAN Connections where multiple sites are involved.

• LAN architecture, including Network Operating Systems deployed

• ICT services deployed, i.e. secure logon, internal/external mail service, Wireless Connections, SQL servers, Antivirus Server, VOIP, Internet Access, etc.

• List and describe all devices deployed, i.e. router, switches, etc. List and describe the Workstations deployed, Hardware specifications, operating systems and standard application software deployed.

Task 2 Evaluation and Performance of the Current ICT Infrastructure

In this section, provide an assessment of the current ICT Infrastructure. At this stage you do not need to propose systems improvements, fixes or modifications. The scope of this section of the project is to provide an assessment and evaluation of the targeted ICT Infrastructure. Examples of issues to be discussed are:

1. Are the WAN links and bandwidth adequate for the company needs? Are users reporting that the system is too slow when accessing websites or resources deployed at remote locations such as other company’s operational sites?

2. During peak time usage such as early in the morning when users are trying to logon at their workstations do they experience extensive delays due to high bandwidth usage and/or user authentication by Domain Controllers

3. Is network storage space adequate for users to save/retrieve their files; or users run out of disk space frequently?

4. Has the system been brought down by virus infestation and/or other issues that caused the suspension of services such as Email, Web Access, SQL Databases, etc.?

5. Are all users granted access to the Internet? Are there one or more Firewalls in place to protect the Network Perimeter?

Task 3 Network Infrastructure Design

In this section, you produce a Network Infrastructure that comprises of two or more operational sites connected together by WAN protocols or VPN application over the Internet.

1. Proposed ICT Infrastructure Overview – Produce an overview of the proposed ICT Infrastructure describing how the network will work and the devices required to produce the required outputs.

2. Network Diagram – Produce a Network Diagram that shows how the two or more operational sites are connected together. Show how the Routers and Servers deployed are connected at their respective operational sites.

3. Network Configuration Table – Produce a network configuration table showing the device names, IP Addresses, Hostnames, Server roles for each deployed servers, IP addresses, Subnet Masks, Default Gateway and preferred DNS Server.

4. Detailed Network Configuration – Produce a Detailed Network Configuration, here you examine individually each deployed device explaining what the device does, how it works and why it is deployed.

Task 4 Server and Security Baseline

In this section, create a Baseline Server Security that is to be applied to all or selected servers in the proposed ICT Infrastructure design. 

You need to produce a complete Server Security Baseline that once deployed the company’s servers shall have increased security without affecting performance levels.

Use the table provided in the template and describe the following:

1. Typical Server Hardware Specification

2. Server Operating System

3. Server Roles deployed

4. Server Roles Security Needs

5. User Account Security

6. Password Security

7. File System Security

8. Physical Security

9. Security Options

10. System Services

11. User Rights Assignment

12. Security Auditing

Task 5 ICT Infrastructure Monitoring

Here you need to tell a story of how the proposed network is to be monitored for performance, for example: 

• you need to address how bottlenecks are managed, 

• how threats to the network and data stored on the servers is to be mitigated, 

• how active directory replication is monitored, 

• list and describe the tools deployed for monitoring the network including hardware and software.
