Main scope of this project is to create the secure wireless network connection for Vancouver State University (VSU). The VSU institutions have the 4000 students and 400 staff and faculty. This campus also has the IT team to improving their network security. The IT Team basically assess the best latest technology to protect the VSU campus network and add the greater authorization and authentication to VSU campus resources by using the 802.1X access control. The Current VSU campus using the open wireless network connection. So, anyone easily accessed the campus network. The VSU team challenged the IT team to determine the solution for open wireless connection issues and provide the cost-effective network. Also, another is hackers are easily accessing the VSU campus important information through the wireless network connection. The wireless users are accessing important information about the campus. So, resolve these issues, VSU interested to create the secure wireless network connection by using the cisco wireless access point. It provides the secure network connection. Because the 802.1x access point authenticate the user after connect the network. To provide the secure wireless connection to implement 802.1X authentication for VSU’s wireless network.
The VSU campus has two main issues. They are,
The VSU campus has open wireless connection to accessing their network. So, every one accessing the VSU wireless connection [1]. Also, hackers are accessing the campus important information. The VSU campus challenged the IT team to resolve these issues. To resolve these issues by creating the secure wireless network. The Hackers are hacking the campus information through the wireless connection. The wireless users are easily accessing the campus sensitive information. The IT team creating the secure wireless connection by implement the 802.1x access point. Because the cisco 802.1x access point provides the secure network. It also provides effective and flexibility of the network. The 802.1x access point authenticates the wireless users, after connect the campus network. So everyone does not access the campus network and also hackers are difficult to accessing the campus sensitive information [2].
The current wireless access point creates the various security problems. So uses the IEEE 802.11b access point. It is most mature wireless technology. It uses the 2.4 GHz ISM band and it provides the 1Mbps speeds to 11 Mbps. It uses the direct sequence speed spectrum to encode the data before transmitting it. In wireless network, these two names are user need to know that is stations and access point [3]. The Stations is wireless network client that is laptop and computer. The access point is a central point that creates the basic service to bridge the number of station from the wireless network to other existing network. It uses the two different modes like Ad hoc mode and Infrastructure mode. The Ad hoc mode is a equivalent to peer to peer networking. It does not have the access point to bridge the stations together. Each station in Ad hoc mode can be communicated with other station in wireless network. The infrastructure mode must be use the more than on access point. It directly connected another network.
The Open wireless connection provides the unsecured wireless network. It is really not safe to connect unknown wireless users. The unknown wireless users are accessing the VSU sensitive information like online banking information. Once user log on to applications or website that transfer the data through wireless network [4]. The information can be easily captured by wireless user. It allows a hacker to accessing your email or personal information in your account. It user do not have a firewall or firewall not configured correctly and user forget to turn off file sharing on user system, a hackers are easily accessing the hard drive through the wireless network. In open wireless network, the hackers are easily capture the transmitted data by using the hacking tools, decrypt and crack the WEP security key on network devices. The open wireless networks are bastions for malicious intent [5].
The current VSU network is open wireless network. It does not provide the secure network for VSU institutions. The VSU institution having the IT team to maintains the network security. So the IT team decided to create the secure wireless network for VSU institutions by using 802.1 x access point [8]. The proposed network infrastructure contains the 802.1x access point and it implemented successfully. The 802.1x access point is used to provide the productivity and security for VSU institutions. The Proposed network infrastructure is using the Cisco products to reduce the operational costs. It Cisco 802.1x access point is used to gives the secure wireless connection. It authenticates the user, after connect the network. So hackers are accessing VSU campus information is difficult. The Implementation of 802.1x access point is authenticate and authorised the wireless users after connect the wireless network [9]. So unwanted users are does not connect the campus network. The Proposed network connection also provides the effective network connection for VSU campus. It also gives the flexibility and scalability of the wireless network. The VSU campus identified issues are resolved by implementing the 802.1x access point wireless connection and also creates the secure wireless connection.
The current network infrastructure allow the hackers to attack the wireless network by using the attack methodology like,
To resolve the identified issues by implement the 802.1x access point for VSU campus network infrastructure [10].
The 802.1x access point offers the unprecedented secure and visibility at the network edge. It is an IEEE standard for layer 2 access control. It offers the capability to permit and deny the network connectivity depends on the identity of the device or end user. It easily enables the post based access control by using the authentication. It can be dynamically enabled or disabled based on the user identification. The 802.1x access point identify and authenticate the user after connect the wireless network. So hackers are does not accessing the VSU campus internet. It provides the greater visibility into the network because the process of authentication provides the way to link a user name with a switch, port, MAC address and IP address [11]. This visibility is useful for trouble shorting, network forensic, network use statistics and security audits. It use the strongest method for authentication and it should be used for managed the assets. The managed assets are support an 802.1x supplicant. It allows user to control the network access at the access point. It basically used to authenticate the users and devices. The 802.1x has the various limitations to enables the visibility and security such as legacy end point support by default ad delay by default. The legacy end point is used to provide the no network access to end point that cannot authenticate the user because they do not support the 802.1x. So 802.1x using the alternative mechanisms to authenticate the end point such as web authentication and MAC authentication bypass. The Delay by default is used to allow no access before authentication. The VSU proposed network infrastructure using the 802.1x access point to provide the secure wireless connection. The IT team was successfully creating the secure wireless connection by implementing the 802.1x access point [12].
Conclusion
The Current VSU network infrastructure does not provide the secure wireless network. So, VSU campus was facing the lot of network problems. It has the IT team to maintain the network security for Campus. The VSU organization team challenged to IT team for resolve the network Problems. The IT team decided to identify the network issues after resolving the identified issues. The IT team was identified the two issues in VSU current infrastructure such as open wireless connection and hackers are accessing campus sensitive information. The identified issues are analysed and discussed in detail. The IT team resolve the network issues by creating the proposed network design. The Proposed network design was successfully created and discussed in detail. The network issues are resolved by implemented the 802.1x access point. The implementation of 802.1x wireless access point can be analysed and discussed in detail.
