Wireless Network Plan

Use the following outline to create your wireless network plan. Fill in each section of the plan as required.

Deployment Scenario

Infrastructure

Deployment Scenario Rationale

An infrastructure wireless network provides a more reliable network connection for wireless clients. If we strategically placed the stationary base we can maximum reception. Infrastructure mode networks offer the advantage of scalability, centralized security management and improved reach.

Hardware Components

• Component Name: Access point o Rationale for using component: Receive and transmit signal that can be picked up by any node that has the ability to receive wireless signals through a wireless network interface card.

o Rough cost estimate: $100

• Component Name: Switches o Rationale for using component: Give the ability to expansion of a WLAN o Rough cost estimate: $250

• Component Name: Cables o Rationale for using component: The access point is connect to wired network with cables to give wireless access o Rough cost estimate:$10

IEEE Wireless Network Type

Apex Designs has identified that an 802.11n LAN will be implemented.

Access Point Management

Apex Designs has decided that thin access points will be used to simplify the management of the wireless LAN. These access points allow the wireless network to be managed from one central location rather than to be configured separately for each access point.

Location of Wireless Devices
Network Performance Impediment Report (overview of floor plan and possible impediments)
This floor doesn’t need a lot of attention. The microwave and the vending machines in one of the rooms could affect the network performance. WLAN operates by RF same as the microwave and the vending machines. This is a customer relation room, probably people will be moving side to side, it’s not a big problem but large amount of people can affect network performance as well.
Summary list of possible impediments to wireless performance • Vending machines • microwave • large group of people • concrete walls

Locations of wireless devices are depicted in Appendix I

Wireless Security Policy

List of Security Protections

• Firewall • Access Control • WEP Implementation • Open System Authentication

Summary of Protections

A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. An Access Control is intended to guard one of the three characteristics of information, mainly the availability of information. Also Access Control controls access to the network, ensures the security policies of customers and assess compliance at the endpoints. Open System Authentication is a process by which a computer can gain access to a wireless network that uses the Wired Equivalent Privacy protocol.

Possible Network Vulnerabilities

• Tampering. The attacker can modify the content of the intercepted packets from the wireless network and this result in a loss of data integrity. • Unauthorized access and spoofing. The attacker could gain access to privileged data and resources in the network by assuming the identity of a valid user. • Eavesdropping. This involves attacks against the confidentiality of the data that is being transmitted across the network.
