is analogous to Ethernet cabling, the answer to this question becomes clear. To share an Internet
connection across a LAN you need two things:
If your LAN is wireless, the same criteria apply. You need a hardware or software access point and
a wireless LAN. Any computer equipped with a wireless network card running suitable Internet
sharing software can be used as a software access point. (See Figure A8) A number of vendors
offer hardware access points.
A hardware access point may provide Internet Sharing capabilities to Wired LAN computers, but
does not usually provide much flexibility beyond very simple configurations. (See Figure A9)

Q8: How can I secure my wireless home network?
Ans: Here are 3 quick steps to help you secure your wireless network from unauthorized access.
These steps are provided as general guidelines - for detailed help, please contact your hardware
vendor.
1. Change the administrator password.
2. Change your SSID and turn off SSID Broadcasting
3. Enable WEP
Q9: What is Virtual Private Networking?
Ans: Typically, a Virtual Private Network (VPN) is defined as a group of two or more computer
systems connected to a private network with limited public-network access that communicates
securely over a public network, such as the internet: Security experts agree that VPNs include
encryption, authentication of remote users or hosts, and mechanisms for hiding or masking
information about private network topology from potential attackers on the public network:
Q10: What is encryption?
Ans: Encryption is a mathematical operation that transforms data from standard text to cipher text.
Usually the mathematical operation requires that an alphanumeric key be supplied along with the
standard text. The key plus standard text is processed by the encryption operation, which
