Question

Home wireless network and security

Methodology- Review topics covered in lecture hours, from textbook, reference books plus online research, to behaviour a comprehensive study about wireless network security implementation at home. Optionally, you can use sniffer like wire shark or your choice to analyze communication traffic- you are required to back up your findings with supporting evidence.

Guidelines-

1. If the last two digit number of your student ID is less than 9, then suppose the number of devices have to to be connected would be the SUM of your last two digits of your student ID PLUS 80; or if your two digit number is larger than nine, ADD 30 to your last 2 digit number would be total number of devices need to be connected; plan your home wireless network with security in mind and explain your rational behind your design;

2. Outline process you approach network design, identify netmask, number of usable IP address; IP address range, subnet and broadcast address for each subnet;

3. What is your router or AccessPoint manufacture's default settings like subnet, gateway address, and default admin account password? How are you going to modify them?

4. Per Internet Protocol stack, layer by layer, elaborate security measures you will like to implement to protect your wireless network and why, as in, enable access control per MAC addresses filtering and constant firmware update at link layer; briefly explain what is stealth mode, what is TCP/UDP port scan, how to determine an invalid source/destination IP address, what are packet flood (SYN/ICMP/other) and how to protect your network from such attacks;

5. Roles of DHCP, NAT, DNS, or previous protocols; including any protocol control based firewall; evaluation of password encryption protocols such as WEP, WPA/WPA2, et al; conduct your online research to see what you can do to secure your wireless network at physical layer beyond physical access restriction.
