Chapter 10 Wireless LAN 10.3.1.1 SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess. This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network. 10.3.1.2 MAC Address Filter Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User's Guide or other documentation. You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings. This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network. 10.3.1.3 Encryption Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. 1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses. 2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. WAP3205 User's Guide 85

10.3.1.1

SSID

Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area.

You can hide the SSID instead, in which case the AP does not broadcast the SSID.

In addition, you should change the default SSID to something that is difficult to

guess.

This type of security is fairly weak, however, because there are ways for

unauthorized devices to get the SSID. In addition, unauthorized devices can still

see the information that is sent in the wireless network.

10.3.1.2

MAC Address Filter

Every wireless client has a unique identification number, called a MAC address.

MAC address is usually written using twelve hexadecimal characters

; for

example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each

wireless client, see the appropriate User’s Guide or other documentation.

You can use the MAC address filter to tell the AP which wireless clients are allowed

or not allowed to use the wireless network. If a wireless client is allowed to use the

wireless network, it still has to have the correct settings (SSID, channel, and

security). If a wireless client is not allowed to use the wireless network, it does not

matter if it has the correct settings.

This type of security does not protect the information that is sent in the wireless

network. Furthermore, there are ways for unauthorized devices to get the MAC

address of an authorized wireless client. Then, they can use that MAC address to

use the wireless network.

10.3.1.3

Encryption

Wireless networks can use encryption to protect the information that is sent in the

wireless network. Encryption is like a secret code. If you do not know the secret

code, you cannot understand the message.

Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks.

These kinds of wireless devices might not have MAC addresses.

Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
