Networking Assignment Report: SYHA Network Design and Analysis

This report presents a comprehensive analysis of a networking assignment for the SYHA organization. It begins with the selection and specification of workstations for different roles, including a secretary and a regional manager, outlining hardware and software recommendations. The report then details the required network services essential for the SYHA office, such as COM+ Event System, DHCP Client, and Workstation services. It also covers the setup of a remote connection to the SYHA network using a Cisco Packet Tracer simulation, illustrating the network's architecture with core, access, and distribution layers, and the use of a wireless tower for remote access. The report further includes an evaluation section with questionnaires to assess the network's performance and security, along with system setup screenshots demonstrating IP address configuration, ping tests, and internet speed tests. A maintenance schedule is provided, covering data backup, routine auditing, and security checks. Finally, the report explores the remote connection of networks using VPN technology, recommending VPN server implementation for secure remote access. A bibliography of relevant sources supports the report's findings.

Recommendations
An iPad is recommended for the SYHA regional manager because according to their
job they need to travel around hostels for finding the condition. Thus they need to carry
portable devices to access the SYHA network from the remote location using the 3G/4G
internet connection where there is no Ethernet or WLAN connections available.
Task 2: Required Services
The key service required for the SYHA office network staffs for connecting with the
local area network and the internet are listed below:
 COM+ Event System – The service is used for supporting the event of system
notification that is used for automatic distribution support and subscription of the
object model components. Closing of the service causes not generation of the logon
and logoff notification.

5
NETWORKING ASSIGNMENT
 Computer Browser – It is used for maintaining a list of the computers connected in
the network and shares the list with the other nodes connected in the network.
Stopping of the service causes no support for updating and maintenance of the list.
 DHCP Client – It is used for the management of the clients connected in the network
and automatically assign the address and the DNS address to the host connected in the
network.
 DNS Client – It is used for maintaining the records of the Domain name system and
also registers the computer with the DNS server. Disabling of the service causes the
computer to display an error message “hostname not resolved” and the result of the
DNS queries would not be cached.
 Network Connections – it is used for management of the objects for the dial up
connection and the network folder and used for viewing the local and the remote
connections.
 Network Location Awareness – It is used for collection and storing the network
information and create a notification on modification of the programs. The
configuration information cannot be retrieved on disabling the service.
 Remote Procedure Call (RPC) – it is used for activation of object requests, distributed
garbage collection and object exporter resolutions from the DCOM or the COM
servers. Disabling of the service would cause the service related to the COM and
DCOM servers to not function properly.
 Server – It is used for sharing files, named pipe and printing jobs in the network.
 TCP/IP Netbios helper – this service is used for getting support about the NetBIOS
and client name resolution for the network. It also helps the user to share files,
logging in and printing files on the network. If the service is disabled then any service
depending on this would fail and the functions would be unavailable.

NETWORKING ASSIGNMENT
 WLAN AutoConfig – it is used for detection of the wireless network and connect with
it if there is an wireless adapter installed in the computer. If the service is not enabled
external third party software can be used for connecting with the wireless network.
 Workstation – It is used for handling the connection between the remote network
resources. The services are used for enabling communication capability for the
network services and if the service is disabled the user cannot connect with the remote
network resources.
It should be checked that all the services are running on the network and the
dependencies should also be checked for identification of any service is preventing other
to run. Diagnosing the event logs can also be used for troubleshooting the failure of the
service running on the workstations.
Task 3: Remote Connection to the SYHA Network
A prototype of the SYHA network is created in cisco packet tracer for the
demonstration of the remote connection between the internal network of the organization and
the external user using the network resources. The network is divided into three layers such
as core, access and distribution layer. A wireless tower is used for connecting the remote
manager with the organizational network. The regional manager connects his wireless device
with the tower by the 3g / 4 g connection to reach the internal network of SYHA.

Task 4: Evaluation
Questionnaires
 What the number of users (total and concurrent) using the network?
 What are the hours of usage of the network?
 Is there any IDS system used by the organization?
 What are the domain name registered by the organization?
 Is there any DMZ for the network?
 Is there any remote access service used by the organization?
 Is there any system using modem?
 Is there any local firewall installed in the network?
 What are service that are exposed to the internet?
 What antivirus application is installed on the workstations?
 What type of authentication is applied for the management of the web service?
 What database technologies are followed by the orgaziation?
Task 5: System Setup Screenshots
a. Setting up of IP address on Windows system

NETWORKING ASSIGNMENT
Discussion
The IP address used to connect with the internet is 192.168.0.2 and it uses the default
route address 192.168.0.1 for sending data packets in the network. The address of the DNS
server is 1.1.1.1.
b. Ping test to www.rdi.co.uk

10
NETWORKING ASSIGNMENT
Discussion
From the ping test it has been found that it takes 122 mili second to reach the website
www.rdi.co.uk. And the server address of the site is 45.60.30.197.
c. Internet connection speed test results
Discussion
Form the speed test it has been found that the current download speed of the network
is 1.02 Mbps and the upload speed is 0.89 Mbps. For the reference a result ID is generated by
Okla.
Task 6: Maintenance Schedule
The routing maintenance task includes the following:
Data backup – The following rules should be set for backing up the data
Rule #1 Go through all of your stuff and see what's irreplaceable.
Important papers and the documents should be encrypted and stored in the remote servers
such that the redundancy off the data is maintained.
Rule #2: Prioritize what is irreplaceable
For saving the space the sensitive organizational information and the important documents
should be backed up.

NETWORKING ASSIGNMENT
Rule #3: Be Redundantly Redundant
The backup should be stored in multiple devices for increasing the redundancy of the data.
Rule #4: Review and Recycle
The backup should be tested such that it can be used for recovery in emergency conditions
Rule #5: Plan for the Disaster
It can be used for handling disaster recovery.
Routine Auditing –
The installation of intrusion detection system and intrusion prevention system can
help in monitoring the activity of the network and control the flow of data packets in the
network. The packets should be captured for finding the unknown requests in the network
and secure the network from external as well as internal threats.
Security checks –
The firewalls must be configured according to the business rules of the organizational
and the log files should be used for auditing and checking the configuration that if it does not
block an user accessing the network.
Task 7: Remote Connection of Networks
For establishing remote connection with the SHYA network the organization can use
VPN to accomplish this. At the head office site, VPN (Virtual Private Network) server should
be created and from the branch office an authentication should be used for connecting with
the server. Since the head office and the English counterpart have the similar network
topology both site needs to have VPN server and it can be connected using the servers.
Creation of a VPN tunnel link with each of the site is an ideal solution for the organization.
