Question

Case Project 9-4: Your Wireless Security
Is the wireless network you own as secure as it should be? Examine your wireless
network or that of a friend or neighbor and determine which security
model it uses. Next, outline the steps it would take to move it to the next
highest level. Estimate how much it would cost and how much time it would
take to increase the level. Finally, estimate how long it would take you to
replace all the data on your computer if it was corrupted by an attacker, and
what you might lose. Would this be motivation to increase your current wireless
security model? Write a one-page paper on your work.

Explanation / Answer

Wireless Security:
To examine the network you can use ipconfig /all command in windows or if you are a linux user type in ifconfig to view all the configuration details of your network such as

indows IP Configuration
Host Name . . . . . . . . . . . . : myvpc-hb
Primary Dns Suffix . . . . . . . : example.com
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . : Yes
Ethernet adapter Local Area Connection:- - - - - -
Connection-specific DNS Suffix . :- - - - - -
Description . . . . . . . . . . : Intel 68540-Based PCI Express Fast Ethernet Adapter
Physical Address. . . . . . . . . : 00-03-AA-BC-CA-8F
Autoconfiguration Enabled . . . . : Yes
Link-local IPv6 Address . . . . . : fe65::ab56:ccb9:320c:524d%8(Preferred)
IPv4 Address. . . . . . . . . . . : 192.168.45.111(Preferred)
Default Gateway . . . . . . . . . : 192.168.15.1
DHCP Server . . . . . . . . . . . : 192.168.15.1
DHCPv6 IAID . . . . . . . . . . . : 201327615
Note: If you want to deeply examine the your network and to find security model go with Wireshark application.It will help you to capture the data packets easily using GUI.Also it will provide other details like transmission control protocols,etc.

To take your network to highest level i.e. to make it more secure you can use:

1.Firewalls like application gateways,packet filtering,hybrid systems.

2.Crypto cable routers

3.Virtual private networks, etc.

Estimation of cost and the time to increase the level is solely depends on the type of the architecture you want to use for the network building structure.Also the size of the network will be responsible for the cost and time.

In case of any attack on your computer it depends on the size of the data on the computer disc and the bandwidth of the network to which your computer is connected to replace all data. The faster the bandwidth of the network,faster the data replacement rate.
