Wireless Security Is Necessary For All Sorts Of Attacks

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:

Interference: When two devices try to access the same WAP and their signals “collide” and cancel each other out. None of the devices manages to fully connect because of it.

To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from

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

Malware consists of viruses which are programs that attach themselves to legitimate programs on a victim’s machine. Worms are standalone programs that do not attach themselves to other programs. Direct propagation words take advantage of vulnerabilities in software. Blended threats propagate both as viruses and worms however; they post themselves on websites for people to download unwillingly. The payrolls are being nine they merely pop up Ace message on the victims computer screen or do something unknowing but nonlethal damage. Trojan horses, hides itself by deleting a system file and taking on the system file name. Remote access Trojan gives the attacker remote control of your computer. These items mentioned above do not rename themselves they can cause great damage or be just a nuisance.

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.

WEP is an older security protocol for wireless networks that encrypts transmitted data. WEP uses a security code chosen during configuration called a WEP key, which uses a sequence of hexadecimal digits. WEP keys can be formed in different lengths depending on the type of WEP encryption being utilized. However it is generally not recommended to use WEP especially when we’re talking about networks that need more advanced security. The biggest disadvantage found with WEP is really it’s main weakness, a skilled hacker could actually crack the security key within a matter of minutes using special software.

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.

The concepts of wireless network security consist of commitment of cyber security and maintaining security based on the latest development and exploits against the network K.W. Ross, J. K. (2012). Wireless Network Security is based on the principles of cryptography, message integrity, authentication, securing e-mails, securing TCP connections: SSL, securing Network layer: IPsec, securing wirelsess: LANs, securing the operational security structure, such as the firewalls and the IDS K.W. Ross, J. K. (2012). This security

While wireless is often considered Ethernet, it uses CSMA/CA (Carrier Sensing Media Access/Collision Avoidance). Wireless network security and signal interference has been a real concern for network administrators. Most of these concerns have been addressed, but the reputation of being a largely free and wide-open media still lingers.

Although there are many threat of WLAN, you still can reduce those threats by applying some technology in your network. For example, you can use a Core Security Standard. It provides protection, which are confidentiality, authentication and message integrity, between the wireless access point and the wireless host. Furthermore, you also can use Wired equivalent privacy (WEP) security. In WEP, everyone shares the same access point, which requires the same key, and WEP’s key is not automated mechanism for changing. On the other hand, Wireless Protected Access (WPA) is also an option for you. WPA is developed by using the concept of Core security standard, so it could be used on older wireless access points and it is stronger than WEP. Finally, 802.11i is another solution for your concerns about the network security. 802.11i is considered as WAP2, and it uses extremely strong AES-CCMP encryption, which has 129-bits keys and a key management method for automatically changing keys. That’s all about the

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model  network structure.
