Overview of security settings

To help improve the security of the wireless network and prevent unauthorized access, the printer

supports many common types of network authentication, including WEP, WPA, and WPA2.

WEP: Provides security by encrypting data sent over radio waves from one wireless device to

another wireless device. Devices on a WEP-enabled network use WEP keys to encode data. If

your network uses WEP, you must know the WEP key(s) it uses.

WPA: Increases the level of over-the-air data protection and access control on existing and

future wireless networks. It addresses all known weaknesses of WEP, the original native security

mechanism in the 802.11 standard. WPA uses the Temporal Key Integrity Protocol (TKIP) for

encryption and employs 802.1X authentication with one of the standard Extensible

Authentication Protocol (EAP) types available today.

WPA2: Provides enterprise and consumer wireless users with a high level of assurance that only

authorized users can access their wireless networks. WPA2 provides the Advanced Encryption

Standard (AES). AES is defined in counter cipher-block chaining mode (CCM) and supports the

Independent Basic Service Set (IBSS) to enable security between client workstations operating

connected wirelessly without a wireless router (such as a Linksys wireless router or Apple

AirPort Base Station).

Add hardware addresses to a wireless router (MAC filtering)

MAC filtering is a security feature in which a wireless router or wireless access point is configured

with a list of hardware addresses (also called "MAC addresses") of devices that are allowed to gain

access to the network through the router.

If the router filters hardware addresses, then the printer's hardware address must be added to the

router's list of accepted hardware addresses. If the router does not have the hardware address of a

printer attempting to access the network, the router denies the printer access to the network.

CAUTION: This method is not recommended, however, because your MAC addresses can easily

be read and falsified by unwanted users outside your network.
