CSCI 1100 GROUP 1 Project 1

1. LANs
Taylor Guinn, Kristen Landino, Julie
Young, Kyron Staley, Ana Pasada

2. WEP
• A security code system for Wi-Fi networks
which allows devices to gather on a local
network
• Exists to distribute encoded information with
other devices in the network while hiding the
content from outsiders
• Mostly used in a home setting

3. WPA
• A security code system for Wi-Fi
• Upgraded version of WEP
• Provides stronger encryption with the help of
TKIP and AES
• Exists to distribute encoded information with
the other devices in the network but has a
stronger encryption than WEP, making it
harder for hackers to hack
• Mostly used in homes

4. WPA-PSK
• Simplified, but stronger version of WPA
• A passphrase is set and with the help is TKIP it
changes at a certain time interval
• Makes it harder to hackers to break into a
network
• Used in Home Networks

5. TKIP
• Designed to provide a more secure encryption
than WEP by adding more code at the
beginning and end of the encryption
• Don’t have to get a hardware upgrade like AES
• Exists because WEP was notoriously weak
• Used for homes and office-like settings

6. AES
• Designed to get rid of flaws of the TKIP
encryption
• Has government approval because it is so secure
• Must have a hardware upgrade for it to be
implemented unlike TKIP
• Exists because it’s the strongest encryption code
which offers the highest level of security
• Used for government settings but can be
implemented in homes

7. Plato’s House

8. Common Items to all Scenarios
• Connect a Wireless Router to Internet Point
– Configure the router:
• Plug in the router
• Connect it to a computer
• Configure
• Access router setup utility
• Create a new router password
• Enter SSID (service set identifier)
• Activate wired equivalent privacy (WEP), WiFi protected
access (WPA), or pre shared key (PSK) and create an
encryption key
• Connect an internet access device

9. Scenario 1 (Wireless Option)
• Wire and install an Access Point to provide
coverage to Computer B and Xbox
– Configure Access Point with the same SSID and
security as the wireless router.
– Configure Access Point with a different
communications channel or automatic so there isn’t
interference with the wireless router.
– Install a wireless NIC in computer B.
– Configure Computer A, B and Xbox to connect to the
wireless network.
– All will have access and the ability to manage ports
and traffic separately.

11. Scenario 2 (Wired)
• Install a wired NIC in Computer A.
• Have the house wired for CAT5 wiring to all
places Internet access is needed. The wiring will
terminate at the Internet access point ether in a
patch panel or directly to the router.
• Configure Computer A, B, and Xbox for DHCP
addressing, so no additional configuration
needed to access the Internet.
• This would most likely be the most expensive but
most stable and secure option.

13. Scenario 3 (Wireless Ad-Hoc)
• Install Wireless NIC in Computer B.
• Configure Computer A to connect to wireless
router, and share it’s internet connection.
• Configure Computer B to connect to Computer A
to connect to the Internet and to share it’s
internet connection.
• Configure Xbox to connect to the Internet via
Computer B’s shared Internet connection.
• This configuration is the most complicated,
unreliable, but the least expensive.

15. Scenario 4 (Hybrid)
• Scenarios 1,2, and 3 show three different methods of
connecting Plato’s mansion to the Internet and providing
access to Computer A, B, and the Xbox, however none
illustrate a “real world” example of a typical home
connection.
• Most homes will have a combination of wired and wireless.
Probably the least expensive and most logical wiring
method would be to relocate the wireless router to a more
central location to province coverage to the whole house,
or use an access point to add coverage.
• Any other devices such as app based TV’s, internet
appliances would be wired directly to the router.
• Bother wired and wireless would be used.
