Information Technology – Structure Of Data

1139 words - 5 pages

"Wireless technology is difficult to connect to other parts of information systems"We are fast approaching the point where it is reasonable to assume that any device that creates or stores data either has, or is connected to, some form of embedded wireless capability. As wireless technology evolves, new devices are being developed to provide more features, functions, portability and ease of use. Mobile phones can provide multiple services including voice, email, text messaging, paging, web access, and voice recognition services. Newer mobile phones incorporate PDA, wireless Internet, email, and global positioning system (GPS) capabilities. Wireless technologies can reduce costs, increase efficiencies, and make important information more readily and widely available. But, there are also risks that cause wireless technologies to become difficult if not handled correctly. Wireless technologies present unique security challenges due in part to the relative immaturity of the technology, incomplete security standards, flawed implementations, limited user awareness, and lax security and administrative practices. Without appropriate safeguards, transmitting data wirelessly can be like using an open filing cabinet in a waiting room.Many organizations and users have found that wireless communications and devices are convenient, flexible, and easy to use. Users of wireless local area network (WLAN) devices have flexibility to move their laptop computers from one place to another within their offices while maintaining connectivity with the network. Wireless personal networks allow users to share data and applications with network systems and other users with compatible devices, without being tied to printer cables and other peripheral device connections. Users of handheld devices such as personal digital assistants (PDAs) and cell phones can synchronize data between PDAs and personal computers and can use network services such as wireless email, web browsing, and Internet access. Further, wireless communications can help organizations cut their wiring costs.Wireless networks and handheld devices are vulnerable to many of the same threats as conventional wired networks. Wireless technologies transmit data through radio frequencies, and are open to intruders unless protected. Intruders have exploited this openness to access systems, destroy or steal data, and launch attacks that tie up network bandwidth and deny service to authorized users. Intruders who gain access to information systems via wireless communications can bypass firewall protection. Once they have accessed systems, intruders can launch denial of service attacks, steal identities, violate the privacy of legitimate users, insert viruses or malicious code, and disable operations. Sensitive information that is transmitted between two wireless devices can be intercepted and disclosed if not protected by strong encryption. Handheld devices, which are easily stolen, can reveal sensitive...
