Information Systems About Mobile And Wireless Networks

One of the very good utilities of the hospitals network is the availability of the wireless access on the ward level, this will insure instant connectivity to the hospitals network from the small mobile devices such as laptops or other Wi-Fi based medical devices such as the new cardiograph devices which shares data with the database servers through wireless connection. These wireless devices depending on the diagram specifications are in 5 gigahertz frequency which are not compatible with every laptop computer, a recommendation to replace them with 2.4 gigahertz frequency devices are more efficient in order to allow laptops to access the network. A special attention is needed in the security of these wireless access points by connecting them to a server like RAS server to authenticate the personnel accessing the network wirelessly before allowing the devices to use the network. This is very important practice to prevent a destructive intrusion into the network.

Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Wireless attacks have becoming a more common security issue when it comes to networks. Attacks can get a lot of information that is being sent across a network and use to commit crimes in other networks. Every wireless network is vulnerable to attacks and it is the important that all the necessary security measures are taken so as to prevent the mess these attacks can cause. These attacks are normally carried out to target information that is being shared through the networks. It is therefore very important to know of such attacks so you will be able to identify the attack when it happens.

Wi-Fi Protected Access 2, the follow on security method to WPA for wireless networks that provides stronger data protection and network access control. It provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

Today we have phones and computers in all types of Wireless technology But in World

The vulnerabilities of wireless networking may involve the attack of web browsers, on-line banking, DNS servers, and routers exchanging routing table updates, purchases, transactions or stolen personal data. The lack of security with a wireless system may result in denial of service, hijacking, fake impersonation, or eavesdropping for interception of messages through cyber-crimes. Each communicating user should select the language of cryptography, agree and share the symmetric key. The best security practices includes firewalls, intrusion detection systems, secured and updated applications, transport, configured properly working network, and link layers.

Mobile computing is the important information system infrastructure. Organization information system mainly get very good benefits from the Mobile computing. From work place and the normal can interact with Mobile computer is made possible by portable computer hardware, software, communication systems that a non-mobile organization information system. The accessibility, improves information quality, enhance management effectiveness all this potentially strategic technology is getting from Mobile computing. I am presenting the detail analysis, by using elucidate and support these asserted benefits of Mobile computing in the organizations. In additionally, a set of MOBILE framework information developed. I am explaining the benefits like defining the types of problems, opportunities and directives of Mobile computing. I am explaining History and efficiency of mobile computing. And I am explaining its business implications.

Wireless technology means that data is sent from one computer to another through a wireless connection. Mobile technology is the way that communicates tasks which are performed. Computing on mobile technology devices, such as laptops, notebooks, PDA etc. It allows the user the flexibility to move and not be confined to the conventional desktop computer.

Wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and or microwaves to maintain communications (Boyds, 2016). Wireless and mobile technologies continue to have a major impact on the global business environment and can be roughly categorized into mobile client devices for interactivity and communications infrastructure. Wireless technology is technology that uses radio waves to transmit and receive data, such as cell phones. It is used more than ever today for data transmission. Mobile

Before designing process it’s very important to analyze the usage of the network? For example, network will be used for business purpose (in offices), schools or hotels etc. If network will be used for business activities like for banks and other offices so administrator needs to deploy network for

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Mobile computing is technology that has enabled users to obtain internet services while being in a state of constant motion. Conventionally, internet could only be accessed only via Ethernet cable and users had to sit on one place in order to access internet. In this way, there existed no concept of taking work to a trip or connecting to world anytime. With the invention of mobile computing, users can take their work in their hands. One can now get internet service anywhere needed.
