Wireless LAN Controllers

Wireless LAN Controllers

The second best practice is to use centralized management. Before wireless LAN controllers were adopted, wireless network management was difficult since each access point used to work autonomously as a separate node. Wireless network controllers are essential for centralized management of the wireless network infrastructure (Barkay, Garti, Klein, & Verrall, 2014). Centralized management can be achieved through various strategies. One of these strategies is establishing a base wireless infrastructure on the wireless controllers. The controllers allow administrators to develop access point groups for geographical security and management. When there is a need to make changes to the wireless network configuration for entire buildings or floors, then the administrator can effectively apply the change through the wireless network controller. The controllers are also essential when it comes to the implementation of features that are normally not featured in normal wireless networks, such as dealing with radio interference. At the same time, centralized management will also ensure that there is increased security as administrators can check logs, implement group securities, and configure security policies from a single point. The controllers also make it easier for one to detect faulty access points and determine if they are compromised or not. In addition to this, centralized management can lead to a lower cost of ownership. The initial investment for setting up thin access points could be higher than that of fat access points but having the ability to manage the access points centrally will significantly reduce management costs. The next strategy is using the FCAPS (Fault, Configuration, Accounting, Performance, and Security) model recommended by ISO. In faults, there is a need to use management solutions that catch, classify, and present faults and events in the network based on their severity. For configuration, there is a need to use global configuration templates which are customized as appropriate. This will ensure consistency. Accounting and performance are concerned with monitoring the network uptime, coverage, load, and utilization and addressing issues on single or multiple devices, depending on the impact of the issue. For security, the system needs to be configured to identify and notify administrators on rogue devices that are having unauthorized access to the network.

The third best practice is the provision of services for the different classes of users (Barkay, Garti, Klein, & Verrall, 2014). To properly serve an organization, the wireless network should provide services needed for each class of user. Several strategies can be implemented to achieve this. The first one is setting up of dedicated enterprise wireless network for employees. This will provide a secure and reliable connection to the corporate network within the office. This will be used with the wireless devices provided by the organization which have advanced security features and remote management tools that are in tandem with the trust model of the enterprise security. The next strategy is to setup a different wireless network for devices owned by the employees. Employees usually require flexibility to do their work on their own devices. This can be achieved using a demilitarized zone which is a subnet that is covered from the internet and intranet through firewalls. For additional security, internet traffic is tunneled through the demilitarized zones through encapsulation over the Wide Area Network. A transparent proxy can also be used to enhance security and performance. If you need a similar paper visit Term Paper. The third strategy is using centralized user management. This involves the use of a RADIUS server which deals with authentication, accounting, and authorizing users. Authentication is confirming that the user is indeed the specified user, authorization is the determination of what resources a user is entitled to and accounting is recording what each user does while connected.
