Understanding Wireless Security

Understanding

Wireless Security

Anyone within range of your wireless network is a potential
security risk. Without wireless security options configured on your
network, a person outside of your physical location, but within
your wireless range may be able to access the network and any
data that is being transmitted over it. SMC Networks’ wireless
devices support the wireless security standard called Wired
Equivalent Privacy (WEP) to prevent unauthorized users from
accessing your network over a wir eless connection. This security
feature uses a secure network key, called a WEP key. The WEP
key encrypts wireless data so that it is only readable by other
computers that have the matching WEP key. The WEP key is
stored on each wireless device, so that data can be encrypted
and decrypted as it is transmitted over the network.

While the Institute of Electrical & Electronics Engineers (IEEE)

802.11i standard is being finalized, an interim solution called

Wi-Fi Protected Access (WPA) has been introduced. The EZ
Connect™ g Wireless Ethernet Bridge is the first device of its
kind to support this new wireless security specification. WPA
defines a set of interoperable se curity enhancements tha t gr eatly
improve upon the level of data encryption and au th e ntic at i on or
access control for e xisting and future wireless LAN systems . WPA
includes Extensible Authentication Protocol (EAP), Temporal Ke y
Integrity Protocol (TKIP) and 802.1X for authentication and
dynamic key exchange. In the WPA-enabled network, the client
first associates with the Access Point. The Access P oint does not
allow network access until the user can be successfully
authenticated. If the client shows the correct credentials to the

8

Understanding Wireless Security

Remote Authentication Dial-In User Service (RADIUS) server, the
client is allowed to join the network. If not, the client stays b loc ked
from joining the LAN. Once the client joins the network, the
authentication server distributes a TKIP encryption key to both
the client and the Access Point. The client can then begin
communicating on the network and maintain the connection,
encrypting data back and forth with the Access Point. Note that
for environments without a Remote A uthentication Dial-In User
Service (RADIUS) infrastructure, WPA supports the use of a
pre-shared key (PSK). WPA-PSK specifies that encryption keys
be dynamically changed (called rekeying) and authenticated
between devices after a specified period of time, or after a
specified number of packets has been transferred.

If you are transferring private information over this wireless
connection, it is recommended to enable WEP or WPA for your
EZ Connect™ g Wireless Ethernet Bridge.

Hardware Installation

Hardware Installation

1. Select the Site – Choose a location f or your Wireless Ethernet

Bridge. Usually, the best location is at the center of your
wireless coverage area, if possible within line-of-sight of all
wireless devices.

2. Place the Wireless Ethernet Bridge in a position that gives it

maximum coverage. Normally, the higher you place the
antenna, the better the performance.

3. Position the antennas in the desired positions. For more

effectiv e cov erage, positio n the antennas along diff erent ax es.
For example, try positioning the antennas arou nd 45 to 90
degrees apart. (The antennas emit signals along the toroidal
plane – and thus provide more effective coverage when
positioned along different axes.)

4. If used in Wireless Bridge mode, connect the Ethernet cable

to the RJ-45 socket of the device will communicate wirelessly
with an access point.

5. If used in Access Point mode, connect the Ethernet cable –

The SMC2870W can be wired to an Ethernet network through
an Ethernet device such as a hub or a switch using category
3, 4, or 5 UTP Ethernet cable and an RJ-45 connector.

6. Connect the power cable – Connect the power adapter cable

to the 5 VDC power socket on the rear panel. Warning: Use
only the power adapter supplied with the SMC2870W.

7. Check the LED’s on the front of the unit to make sure the

adapter is turned on properly and the status is okay.

Note that when configured as a Wireless Bridge, changing the
channel of the SMC2870W has no effect b ecause it must connect
to the network using the same channel as your Access Point. If
you wish to use a diff erent cha nnel, you m ust change th e channel
in your Access Point’s configuration.

32

Internet Explorer in Macintosh

Go to Wireless | Advanced Settings in order to change the
Fragmentation and RTS thresholds. (Note: It is recommended to
leave these values at their default settings.)

RTS Threshold: Set the R TS (Request to Send) frame length . You
may configure the access p oint to initiate an RTS frame. If the
packet size is smaller than the preset RTS threshold size, the
RTS/CTS mechanism will NO T be enabled.

The access point sends Request to Send (R TS) frames to a
particular receiving station to negotiate the sending of a data
frame. After receiving an RTS, the station sends a CTS (Clear to
Send) frame to acknowledge the right of the sending sta tion to
send data frames. The access points contending for the medium
may not be aware of each other. The RTS/CTS mechanism can
solve this “Hidden Node Problem.”

Fragmentation Threshold: If the packet size is smaller than the
preset Fragment size, the packet will not be segmented.
Fr agmentation of the PDUs (P ac kage Data Unit) ca n increase the
reliability of transmissions because it increases the probability of
a successful transmission due to smaller frame size. If there is
significant interference present, or collisions due to high network
utilization, try setting the fragment size to send smaller fragments.
This will enable the retransmission of smaller frames much f aster .

33

Advanced Web Configuration (Wireless Bridge mode)

However, it is more efficient to set the fragment size larger if very
little or no interf erence is prese nt because it r equires overhead to
send multiple frames.

Go to Wireless | Security to configure wireless security. If you
have Wi-Fi Protected Access (WPA) security enabled on your
wireless LAN, please click the [WPA enabled] checkb ox and en ter
your pre-shared key (PSK):

If you have Wired Equivalent Privacy (WEP) security enabled on
your wireless LAN, please click the [Enable WEP] checkbox.
Then enter your desired k e y length and def ault WEP k e y. You can
use the Passphrase function to automatically generate a WEP
key or you can enter the full 10-digit (64-bit WEP) or 26-digit
(128-bit WEP) manually in the “WEP key” field. Select your
“Authentication” method and press [Save].

34

Note: A passphrase can contain up to 32 alphanumeric

characters.

When setting up WEP without using the Passphrase function,
only Hexadecimal char acters (r a nge: 0~9 and A~F) ca n b e used.
When encryption is set to 64-bit, a maximum of 10 Hex
characters can be entered in the K e y field. When encryption is set
to 128-bit, a maximum of 26 Hex characters can be used.

Advanced Web Configuration (Access Point mode)

After logging into the SMC2870W, all the System Information will
be displayed. You can proceed to another configuration page
using the navigational menu on the left.

Go to the Status | Associations page to view all the wireless
clients that are connected to your SMC2870W. The MAC
Addresses of the clients will be shown. This is helpful if you plan
to configure MAC Address Filtering in the future. You can simply
highlight the appropriate MAC Address, copy and paste it in the
section called Wireless | Access List.

Go to Wireless | Basic Settings to change parameters such as the
SSID, channel, and transmit rate. You can also change the
“Visibility Status”. Selecting [Visible] enables SSID broadcast
whereas selecting [Invisible] disables the SSID broadcast. The
“Wireless Mode” dictates what type of wireless client is allowed to

associate to the SMC2870W. The supported modes are Mixed
(11b+11g), Long Range Mixed (11b+11g), 11g Only, and 11b
Only.

41

Advanced Web Configuration (Access Point mode)

Go to Wireless | Access List to enter specific MAC Addresses
that are allowed to connect to the SMC2870W. This function
gives you added security without the ov erhead and increased
processing that WEP or WPA may require.

42

Browser Configuration

Go to Wireless | Repeater to make use of the repeating
functionality to extend the wireless range of your network. (Note:
You need at least two SMC2870W units in order to successfully
enable repeating on your wireless LAN)

This function makes use of Wireless Distribution System (WDS)
technology. You can specify up to six WDS links, where each link
is defined by the MAC addresses of the other repeater capable
SMC2870W. (Note: The repeater function must be enabled on
both ends in order to function properly.)

43

Advanced Web Configuration (Access Point mode)

Go to Wireless | Advanced Settings in order to change the
Fragmentation and RTS thresholds. (Note: It is recommended to
leave these values at their default settings.)

44

RTS Threshold: Set the R TS (Request to Send) frame length . You
may configure the access p oint to initiate an RTS frame. If the
packet size is smaller than the preset RTS threshold size, the
RTS/CTS mechanism will NO T be enabled.

The access point sends Request to Send (R TS) frames to a
particular receiving station to negotiate the sending of a data
frame. After receiving an RTS, the station sends a CTS (Clear to
Send) frame to acknowledge the right of the sending sta tion to
send data frames. The access points contending for the medium
may not be aware of each other. The RTS/CTS mechanism can
solve this “Hidden Node Problem.”

Browser Configuration

Fragmentation Threshold: If the packet size is smaller than the
preset Fragment size, the packet will not be segmented.
Fr agmentation of the PDUs (P ac kage Data Unit) ca n increase the
reliability of transmissions because it increases the probability of
a successful transmission due to smaller frame size. If there is
significant interference present, or collisions due to high network
utilization, try setting the fragment size to send smaller fragments.
This will enable the retransmission of smaller frames much f aster .
However, it is more efficient to set the fragment size larger if very
little or no interf erence is prese nt because it r equires overhead to
send multiple frames.

Beacon Interval: Set the interval value of beacon between
synchronized frames. These synchronous frames also contain
indication of frames that need to transmit to the power-saved
stations.

DTIM: Set the Delivery Traffic Indication Message (DTIM) interval
value. The DTIM indicates how often the MAC layer forwards
multicast traffic. This parameter is necessary to accommodate
stations using Power Save mode. In order to maximize the
utilization of channels, broadcast data is not transmitted every
beacon for stations in Power Save mode. These power-saved
stations must wake up to receive broadcast data at the DTIM
interval. The DTIM is the interval between two synchronous
frames with broadcast information. If you set the value to 2, the
access point will save all mult icast frames for the BSS and
forward them after every second beacon. Having smaller DTIM
intervals delivers multicast frames in a more timely manner,
causing stations in Power Save mode to wake up more often an d
drain power faster. Having higher DTIM values, though, delays
the transmission of multicast frames.

Go to Wireless | Security to configure wireless security. Please
click the [WPA enabled] checkbox and enter your desired

45

Advanced Web Configuration (Access Point mode)

pre-shared key (PSK) if you want to enable Wi-Fi Protected
Access (WPA) security on your wireless LAN. You can also set
the “WPA Group K ey Update Interval” value. This specifies how
often the wireless encryption keys are dynamically changed and
clients re-authenticate.

46

Browser Configuration

If you have a RADIUS server on your network, you can configure
the SMC2870W to use it for the purpose of authenticating clients
to your wireless LAN. Simply click the [802.1x enabled] chec kbox
and enter your settings:

Please click the [Enable WEP] checkbox if you want to enable
Wired Equivalent Privacy (WEP) security on your wireless LAN.
Then enter your desired k e y length and def ault WEP k e y. You can
use the Passphrase function to automatically generate a WEP
key or you can enter the full 10-digit (64-bit WEP) or 26-digit
(128-bit WEP) manually in the “WEP key” field. Select your
“Authentication” method and press [Save].

47

Terminology

10BaseT - Physical Layer Specification for Twisted-Pair Ethernet
using Unshielded Twisted Pair wire at 10Mbps. This is the most
popular type of LAN cable used today because it is very cheap
and easy to install. It uses RJ-45 connectors and has a cable
length span of up to 100 meters. There are two versions, STP
(Shielded Twisted Pair) which is more expensive and UTP
(Unshielded Twisted Pair), the most popular cable. These cables
come in 5 different categories. However, only 3 are normally used
in LANs, Category 3, 4 and 5. CAT 3 TP (Twisted Pair) cable has
a network data transfe r rate of up to 10M bps. CAT 4 TP cable has

Terminology

a network data transfe r rate of up to 16M bps. CAT 5 TP cable has
a network data transfer rate of up to 100Mbps.

Access Point - A device that is able to receive wireless signals
and transmit them to the wired network, and vice versa - thereby
creating a connection between the wireless and wired networks.

Ad Hoc - An ad hoc wireless LAN is a group of computers, each
with LAN adapters, connected as an independent wireless LAN.

Adapter - A device used to connect end-user nodes to the
network; each contains an interfac e to a specific type of computer
or system bus, e.g. EISA, ISA, PCI, PCMCIA, CardBus, etc.

Auto-Negotiation - A signaling method that allows each node to
define its operational mode (e.g., 10/100 Mbps and half/full
duplex) and to detect the operational mode of the adjacent node.

Backbone - The core infrastructure of a network. The portion of
the network that transports information from one central location
to another central location where it is unloaded onto a local
system.

60

Terminology

Base Station - In mobile telecommunications, a base station is
the central radio transmitter/receiver that maintains
communications with the mobile radiotelephone sets within its
range. In cellular and personal communications applications,
each cell or micro-cell has its o wn base station; each ba se station
in turn is interconnected with other cells' bases.

BSS - BSS stands for "Basic Service Set". It is an Access P oint
and all the LAN PCs that are associated with it.

CSMA/CA - Carrier Sense Multiple Access with Collision
Avoidance

DHCP - Dynamic Host Configuration Protocol. This protocol
automatically configures the TCP/IP settings of every computer
on your home network.

DNS - DNS stands for Domain Name System, which allows
Internet host computers to have a domain name (such as
www.smc.com) and one or more IP addresses (such as

192.34.45.8). A DNS server keeps a database of host co mputers
and their respective domain names and IP addresses, so that
when a domain name is requested (as in typing " www.smc.com"
into your Internet browser), the user is sent to the proper IP
address. The DNS server address use d by the computers on y our
home network is the location of the DNS server your ISP has
assigned.

DSL - DSL stands for Digital Subscriber Line. A DSL modem
uses your existing phone lines to transmit data at high speeds.

EAP - (Extensible Authentication Protocol) This is a mode of
conv ersation between a Supplican t and an A uthentication Server.
Access Points or proxy servers do not take part in the
conversation. Their role is simply to forward EAP messages
between the parties performing the authentication. The EAP

61

Terminology

messages are transported between a wireless station and an

802.1X Authenticator using EAPOL. The EAP messages are sent
between an 802.1X Authenticator and the Authentication Server
using RADIUS. The EAP framework supports the definition of
EAP-Type Authentication Methods. Today, the major EAP-Type
Authentication Methods include EAP-MD5, EAP-TLS , EAP-TTLS,
EAP-PEAP, and Cisco’s EAP-LEAP.

EAP-MD5 - This is the most basic EAP-Type, which must be
supported by all implementations of EAP. It is not a strong
authentication method and does not support dynamic WEP keys.

EAP-LEAP - (Lightweight Extensible Auth entication Protocol) It is
the type primarily used on Cisco WLAN access points. LEAP
provides security during credential exchange, encrypts using
dynamic WEP keys, and supports mutual authentication.

EAP-TLS - (Transpor t Layer Security) This us es th e TL S
handshake as the basis for authentication. TLS performs
authentication by exchanging digital certificates. The server
sends a certificate to the client and only after validating the
server's certificate does the client present a client certificate.

EAP-TTLS - (Tunneled TLS) This mode an advantage over
EAP-TLS that it only requires a certificate at the Authentication
Server.

Ethernet - A standard for computer networks. Ethernet networks
are connected by spe cial cables and hubs , and mov e data around
at up to 10 million bits per second (Mbps).

ESS - ESS (ESS-ID, SSID) stands for "Extended Service Set".
More than one BSS is configured to become an Extended
Service Set. LAN mobile users can roam between different BSSs
in an ESS (ESS-ID, SSID).

62

Terminology

Fast Ethernet NIC - Network interface card that is in compliance
with the IEEE 802.3u standard. This card functions at the media
access control (MAC) layer, using carrier sense multiple access
with collision detection (CSMA/CD).

Fixed IP – (see Static IP)
Full-Duplex - Transmitting and receiving data simultaneously. In

pure digital networks, this is achieved with two pairs of wires. In
analog networks, or digital networks using carriers, it is achieved
by dividing the bandwidth of the line into two frequencies, one for
sending, one for receiving.

Hub - Central connection device for shared media in a star
topology. It may add nothing to the transmission (passive hub) or
may contain electronics that regenerate signals to boost strength
as well as monitor activity (active/intelligent hub). Hubs may be
added to bu s topo logies; for example, a hub can turn an Ethernet
network into a star topology to improve troubleshooting.

IP Address - IP stands for Internet Protocol. An IP address
consists of a series of four numbers separated by periods, that
identifies an single, unique Internet computer host. Example:

192.34.45.8.
ISP - Internet Service Provider. An ISP is a business that

provides connectivity to the Internet for individuals and other
businesses or organizations.

LAN - A communications network that serves users within a
confined geographical area. It is made up of servers,
workstations, a network operating system and a comm un ications
link. Servers are high-speed machines that hold programs and
data shared by network users. The workstations (clients) are the
users' personal computers, which perform stand-alone
processing and access the network servers as required.

63

Terminology

Diskless and floppy-only workstations are sometimes used, which
retrieve all software and data from the server. Increasingly, "thin
client" network computers (NCs) and Windows terminals are also
used. A printer can be attached locally to a workstation or to a
server and be shared by network users. Small LANs can allow
certain workstations to function as a server, allowing users
access to data on another user's machine. These peer-to-peer
networks are often simpler to install and manage, but dedicated
servers provide better performance and can handle higher
transaction volume. Multiple servers are used in large networks.

MAC Address - MAC (Media Access Control) A MAC address is
the hardware address of a device connected to a network.

MDI / MDI-X - Medium Dependent Interface - Also called an
"uplink port," it is a port on a network hub or switch used to
connect to other hubs or switches without requiring a crossover
cable. The MDI po rt does not cross the transmit and receive lines,
which is done by the regular ports (MDI-X ports) that connect to
end stations. The MDI port connects to the MDI-X port on the
other device . There are typically one or two ports on a device that
can be toggled between MDI (not crossed) and MDI-X (crossed).

Medium Dependent Interface – X (crossed) - A port on a
network hub or switch that crosses the transmit lines coming in to
the receive lines going out.

NAT – (Network Address Translation) This process allows all of
the computers on your home network to use one IP address. The
NAT capability of the Barricade, allows you to access the Internet
from any computer on your home network witho ut having to
purchase more IP addresses from your ISP. Network Address
Translation can be used to give multiple users access to the
Internet with a single user account, or to map the local address
for an IP server (such as Web or FTP) to a public address. This
secures your network from direct attack by hackers, and provides

64

Terminology

more flexible management by allowing you to change internal IP
addresses without affecting outside access to your network. NAT
must be enabled to pro vide multi-user access to the Internet or to
use the Virtual Server function.

Packet Binary Con vulational Code(

tm

) (PBCC) - A modulation

technique developed b y Texas Instruments Inc. (TI) that offers
data rates of up to 22Mbit/s and is fully bac kw ard compatible with
existing 802.11b wirel ess networks.

PCI - Peripheral Component Interconnect - Local bus for PCs
from Intel that provides a high-spe ed data path betw een the CPU
and up to 10 peripherals (video , disk, netw ork, etc.). The PCI bus
runs at 33MHz, supports 32-bit and 64-bit data paths, and bus
mastering.

PPPoE - Point-to-P oint Protocol over Ethernet. Point-to-Point
Protocol is a method of secure data transmission originally
created for dial-up connections. PPPoE is for Ethernet
connections.

Roaming - A function that allows your to move through a
particular domain without losing network connectivity.

Static IP - If your Service Provider has assigned a fixed IP
address; enter the assigned IP address, subnet mask and the
gateway address provided by your service provider.

Subnet Mask - A subnet mask, which may be a part of the TCP/
IP information provided by your ISP, is a set of four numbers
configured like an IP address. It is used to create IP address
numbers used only within a particular network (as opposed to
valid IP address num bers recognized by the Internet.

TKIP - (Temporal Key Integrity Protocol) The TKIP process
begins with a 128-bit "temporal key" which is shared among

65

Terminology

clients and access points. Then it combines the tempor al ke y with
the client's MAC address and adds a 16-octet initialization vector
to create the key that will encrypt the data. This procedure
ensures that each station uses different key streams to encrypt
the data.

TCP/IP - Transmission Control Protocol/Internet Protocol. This is
the standard protocol for data transmission over the Internet.

TCP - Transmission Control Protocol - TCP and UDP (User
Datagram Protocol) are the two transport protocols in TCP/IP.
TCP ensures that a message is sent accurately and in its entirety.
However, for real-time voice and video, there is really no time or
reason to correct errors , and UDP is used instead.

UDP - User Datagram Protocol - A protocol within the TCP/IP
protocol suite that is used in place of TCP when a reliable
delivery is not required. For example, UDP is used for real-time
audio and video traffic where lost packets are simply ignored,
because there is no time to retransmit. If UDP is used and a
reliable delivery is required, packet sequence checking and error
notification must be written into the ap plic at ion s.

Wi-Fi Protected Access (WPA) – Wi-Fi Protected Access (WP A)
is a set of interoperable security improvements that greatly
increase the level of data encryption and authentication for
existing and future wireless LAN systems . It solves se veral issues
with the widely used WEP standard.

Wired Equivalent Privacy (WEP) - “Wired Equiv a lent Privacy” is
based on the use of 64-bit or 128-bit keys and the popular RC4
encryption algor ithm. Wireless devices without a valid WEP key
will be excluded from network traffic.
