Chapter 12 You Learned Wired networks typically rely on physical security to protect the privacy of their communications. However, if a wireless network is not properly secured, an intruder in a car parked outside can use a laptop to gain full access to the network’s communications.

Chapter 12 You Learned (cont.) The standards published by the Institute of Electrical and Electronic Engineers (IEEE) dictate the frequencies, transmission speeds, and ranges of wireless networking products. WEP is a wireless security protocol that helps protect transmitted information by using a security setting, called a shared secret or a shared key, to encrypt network traffic before sending it.

Chapter 12 You Learned (cont.) Although shared secret authentication is stronger than an open system for authentication, it weakens the WEP encryption. WPA encrypts data using the RC4 algorithm with a 128-bit key. This is the same algorithm as WEP, but TKIP virtually eliminates WEP’s most exploited vulnerability by using a unique encryption key for each packet.

Chapter 12 You Learned (cont.) Implemented in the WPA2 standard, AES uses a different and more secure encryption algorithm called CCMP. Laptop computers have a Mobile PC control panel, which consolidates many of Vista’s most frequently used configuration settings in one place.

Chapter 12 You Learned (cont.) Windows Mobility Center is a shell application that provides a central point of access for many of the configuration settings that mobile computer users need frequently. Most laptop computers have the capability to connect an external display device, making it possible for a group of users to view the desktop without having to crowd around a single screen.

Chapter 12 You Learned (cont.) To conserve battery power as much as possible, virtually all laptops include the hardware and firmware elements needed to dynamically adjust the power consumption of individual components.

Chapter 12 You Learned (cont.) Windows Vista includes a dialog box that bundles together the configuration settings that users most often adjust before giving a presentation and make it possible to activate all of the settings with a single switch. Windows Vista includes the ability to store copies of network files on the local drive for use when the computer is disconnected.

Chapter 12 You Learned (cont.) Sync Center is an application that functions as a central control panel for all of a Windows Vista computer’s synchronization partnerships, including those with network drives and mobile devices.

Chapter 12 You Learned (cont.) Windows SideShow is a new feature in Windows Vista designed to accommodate a new secondary display technology that is currently being integrated into a wide variety of products.

Chapter 12 You Learned (cont.) A tablet PC’s entire display is touch sensitive, enabling users to tap screen buttons with a finger or tap, click, drag, and write directly on the screen using a stylus. Windows Vista also includes handwriting recognition capabilities that convert the handwriting into digital text.
