Best Practice Wireless Case Study

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:

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

Users that have a wireless LAN should add security to ensure only intended users have access. Some safeguards include use of WEP (Wired Equivalent Privacy) encryption, IPsec, WPA (WiFi Protected Access), with a firewall or DMZ. A DMZ (demilitarized zone) is a physical or logical sub-network that separates the LAN from other entrusted networks

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.

Wireless networks have become a major part in the operation of businesses and in people’s lives. Wireless networks can provide fast speed internet connections without having to use wired connections. Businesses are doing much better with wireless networks because they don’t have to pay the costs of installing wired networks and people can work easier because they do not have wires running all over the place. Now with wireless networks in place, businesses are able to connect to their other branches and buildings within their area as well.

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.

1. List two advantages of wireless networking. User mobility in the workplace, and cost effective networking media for use in areas that are difficult or too costly to wire.

Because this is going to incorporate a whole campus there will be a wireless receiver at the top of every building. However we will have them all in together so that way they work as one and a student will be able to access any of them from any location and allow them to transition from one to another with ease. We will also incorporate a repeater on the bottom floor to allow for full building coverage and to extend the network throughout the campus itself. The Only Exception will be for the library and in the library we will have a strict Network that will allow for the students to be able to access specific training material and the library's internal architecture. The equipment itself will be a very good Mount of switches and routers to allow for easy authentication and access. The equipment will be scattered throughout each building and we will ensure that there is proper coverage of the wireless network and proper capability of the staff meeting to be able to handle the amount of devices inside of the

As far as the IT department is concerned the need for running cables is no longer there, all you need is a bunch of repeaters at every floor of a building strengthen the wireless signal. With wireless networking configuration is easy one only need a password to be part of the network. The network administrator also has an easy time controlling the traffic in the network. To

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.

The 802.11 provides the wireless LAN services for the clients, the access points, and the network connecting them. The association service is used by mobile stations to connect themselves to APs. Reassociation lets a station change its preferred AP. Either the station or the AP may also disassociate, breaking their relationship. Stations must authenticate to use a security scheme before they can send frames via the AP. With WPA2, the AP can talk to an authentication server that has a username and password database to determine if the station is allowed to access the network. Before WPA, WEP is used but it is easy to compromise. The distribution service determines the route for wireless or wired network. The integration service is used when

Wireless networks are required to be connected the internet, therefore if it is not secured properly, savvy hackers could easily intrude. Most people know the obvious first step of securing a wireless network: passwords. Passwords are key parts to keeping a network’s privacy intact. When a new network it setup, it usually comes with a standard password such as “password” or no password at all. Changing this password is always the first step to securing a network. Most people like to use passwords they can remember and often use for everything else, however, people must refrain from doing that. A good, strong password is consisted of

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

The wireless network consists of four fundamental components: The transmission of data, utilizing radio frequencies, Access points (AP) which provide a connection to the organization 's network or private network and users. All of these components provide a way for an attack which can result in compromise of security objectives of availability, integrity and confidentiality.
