Wireless Security B • MAC Addresses. Enable MAC address filtering. MAC address filtering allows you to provide access to only those wireless nodes with certain MAC addresses. This makes it harder for a hacker to access your network with a random MAC address. • WEP Encryption. WEP is often looked upon as a cure-all for wireless security concerns. This is overstating WEP's ability. Again, this can only provide enough security to make a hacker's job more difficult. There are several ways that WEP can be maximized: - Use the highest level of encryption possible. - Use "Shared Key" authentication. - Change your WEP key regularly. • WPA/WPA2 Personal. The WPA-Personal and WPA2-Personal methods offer two encryption methods, TKIP and AES, with dynamic encryption keys. • WPA /WPA2 Enterprise. The WPA-Enterprise and WPA2-Enterprise option requires that your network has a RADIUS server for authentication. A network encrypted with WPA/WPA2 is more secure than a network encrypted with WEP, because WPA/WPA2 uses dynamic key encryption. To protect the information as it passes over the airwaves, you should enable the highest protection level. Implementing encryption may have a negative impact on your network's performance, but if you are transmitting sensitive data over your network, encryption should be used. CAUTION: Always remember that each device ! in your wireless network must use the same encryption method and encryption key or your wireless network will not function properly.
