Implementation of Security for Wireless Network R.Sridevi (Asst.Prof) Department of Computer Science PSG College of Arts amp; Science Coimbatore, TN. srinashok@gmail.com Abstract -This paper addresses the internal and the external security challenges in organizations that implements wireless networks. Distributed security is designed to provide a more secure data communication among faculty members, staff and students. A description of the technique used to protect and keep PC s up and running is illustrated with applications. Keywords: Access point, LAN. 1.

Use of Intrawalls: Firewalls that separate an organization from the Internet are blind to attacks launched by unwitting insiders and hostile insiders. These firewalls may provide some protection unless client to server VPNs are used. These VPNs effectively blind perimeter firewalls. The firewall functions may be moved deeper into the network. Intrawalls suffer from the following shortcomings. 2. Use of Network Edge Security: Network Edge Security is the second-generation firewall architecture which changes 1st generation firewall paradigms. Network Edge Security pushes network security policy enforcement to the edge of the network (in other words all the way to the host) to address the insider problem. The architecture is not host-based software such as personal firewall but it is a host operating system independent and hardware based implementation on NIC (network interface card), with its own processor and memory that cannot be accessed by the host [5].

After policies are outlined, standards are defined to set the mandatory rules that will be used to implement the policies. Some policies can have multiple guidelines, which are recommendations as to how the policies can be implemented. Finally, information security management, administratorsRead MoreThe Security Issues Revolving Around Wireless Networks1668 Words   |  7 PagesIntroduction Wireless computer networks have become very common in the past several years. The convenience with which computer users can utilize internet connections, without having a network cable attached to their computers, makes wireless networks extraordinarily popular in today’s on-the-go society. Homes, offices, and public businesses (e.g., hotels, coffee shops, restaurants, etc.) all frequently have active wireless computer networks. As is the case with hard-wired computer networks, security isRead MoreExamples Of AC-7 : System Use Notification715 Words   |  3 PagesAC-7: System Use Notification The information system notification displays an approved system use notification message or banner before granting access to the system that provides privacy and security notices screen until users take consistent with applicable federal laws.

Attempts to breach networks are becoming more sophisticated and difficult to defend against, as more powerful hardware is introduced and new security defenses become available leaving older measures unreliable. Aging networks that are improperly secured are more at risk than ever. It is not only important to ensure you have the proper defense at the perimeter but also internally on wired and wireless infrastructure.
