Question

Options

• ASSID
• BWAP
• CWTLS
• DWEP

Explanation

SSID stands for Service Set Identifier. It is used to identify a wireless network. SSIDs are case sensitive text strings and have a maximum length of 32 characters. All wireless devices on a wireless network must have the same SSID in order to communicate with each other. The SSID on computers and the devices in WLAN can be set manually or automatically. Configuring the same SSID as that of the other Wireless Access Points (WAPs) of other networks will create a conflict. A network administrator often uses a public SSID that is set on the access point. The access point broadcasts SSID to all wireless devices within its range. Some newer wireless access points have the ability to disable the automatic SSID broadcast feature in order to improve the network security. Answer option D is incorrect. Wired Equivalent Privacy (WEP) is a security protocol for wireless local area networks (WLANs). It has two components, authentication and encryption. It provides security, which is equivalent to wired networks, for wireless networks. WEP encrypts data on a wireless network by using a fixed secret key. WEP incorporates a checksum in each frame to provide protection against the attacks that attempt to reveal the key stream. Answer option B is incorrect. The Wireless Access Protocol (WAP) is a technology used with wireless devices. The functionality of WAP is equivalent to that of TCP/IP. WAP uses a smaller version of HTML called Wireless Markup Language (WML) to display Internet sites. Answer option C is incorrect. Wireless Transport Layer Security (WTLS) is a security layer of WAP, which is specifically designed for a wireless environment. It provides privacy, data integrity, and authentication for client-server communications over a wireless network. WTLS ensures that a client and server are authenticated so that wireless transactions remain secure and the connection is encrypted. WTLS is required because a wireless network does not provide end-to-
