Wireless Security Overview Wireless networks serve as the transport mechanism between devices and among devices and the traditional wired networks (enterprise networks and the Internet). Wireless networks are many and diverse but are frequently categorized into three groups based on their coverage range: Wireless Wide Area Networks (WWAN), Wireless Local Area Network (WLANs), Wireless Personal Area Network (WPAN )and etc. WWAN includes wide coverage area technologies such as 2G cellular, Cellular Digital Packet Data (CDPD), Global System for Mobile Communications (GSM). WLAN, representing wireless local area networks, includes 802.11, HiperLAN, and several others. WPAN, represents wireless personal area network technologies such as Bluetooth and IR All of these represent potential threats in wireless networks as well. However, the more immediate concerns for wireless communications are: †¢ Denial of service †¢ Malicious hackers †¢ Theft of service (Identity theft / MAC spoofing) In wireless security, information must be protected from unauthorized, unanticipated, or unintentional modification. Security requirements include the following: †¢ Authenticity—A third party must be able to verify that the content of a message has not been changed in transit. †¢ Nonrepudiation—The origin or the receipt of a specific message must be verifiable by a third party. †¢ Accountability—The actions of an entity must be traceable uniquely to that entity.

As the wireless communication has the different way of physical transport compared to wire environment of communication thus we have to use different measure to secure a network in wireless environment. Wireless networking has more security threats and vulnerabilities and we must have an effectiveRead MoreWireless Sensors Networks Security1991 Words   |  8 Pagessystems (MEMS) and wireless networks are opening a new domain in networking history. Sensors; often called smart dust are low cost small tiny devices with limited coverage, low power, smaller memory sizes and low bandwidth, will play a key role in collecting and disseminating data from the fields where ordinary networks are unreachable for various environmental and strategical reasons. There have been significant contributions to overcome many weaknesses in sensor networks like coverage problemsRead MoreThe Security Issues Revolving Around Wireless Networks1668 Words   |  7 PagesIntroduction Wireless computer networks have become very common in the past several years. The convenience with which computer users can utilize internet connections, without having a network cable attached to their computers, makes wireless networks extraordinarily popular in today’s on-the-go society. Homes, offices, and public businesses (e.g., hotels, coffee shops, restaurants, etc.) all frequently have active wireless computer networks. As is the case with hard-wired computer networks, security isRead MoreSecurity Issues Of Wireless Sensor Networks1286 Words   |  6 PagesSecurity issues in Wireless Sensor Networks What the security issues are related to Wireless Sensor Networks Name:Sandeep Kumar Pulijala Student ID:S0261345 Teacher:Erin Class:DEA3 Central Queensland University What the security issues are related to Wireless Sensor Networks Wireless sensor networks are very important in everyday life.
