TNC is basically used for NAC (Authentication Purpose). The Architecture of NAC provides a clear background of how a network can be made secure and how to avoid unauthorized access. IEEE 802.1x is a standard which provide port based network access control and protect the network from unauthorized access. If the access register is unauthorized then access is given but access is not given when the access is unauthorized. IEEE 802.1x is basically used for authentication and authorization purpose. This
this case is usually stored on an access point. In such environment setup, the authentication takes place between the station and the access point. To secure the network setup, WPA2 can be used along with the optional Pre-Shared Key (PSK) for authentication. To encrypt the network with WPA2-PSK, the router is configured not with an encryption key but rather plain paraphrase. TKIP(for Temporal Key Integrity Protocol) is used along with the network SSID for generating unique encryption key for the

create and maintain throughout Windows based systems. Wikipedia describes Active Directory with the definition: Active Directory is an implementation of Lightweight Directory Access Protocol (LDAP) directory services by Microsoft for use primarily in Windows environments. Its main purpose is to provide central authentication and authorization services for Windows based computers. Active Directory also allows administrators to assign policies, deploy software, and apply critical updates to an organization
The WPS protocol relies on an eight digit Personal Identification Number (PIN) to allow the authentication of users on to the network. The protocol further relies on a session of eight Extensible Authentication Protocol (EAP) messages that are followed by a final message which identifies the successful completion of the session. WPS automatically configures the network name (SSID) and the WPA security key for the access point and the WPS enabled client. The benefit is that a user does not need to

Introduction Wireless networks have grown in popularity. This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in 'Metcalf's law.' Metcalf's law states that if you 'connect any number, 'n,' of machines - whether computers, phones or even cars - and you get 'n' squared potential value.'[1] The incredible growth of the Internet seems to validate Metcalf's law. It then seems
Chapter 1 : Introduction Cloud computing : Cloud computing is a new class of network based computing that takes place over the internet. Large number of remote servers are allow to centralized data storage and there is online access to computer resources and services. Characteristic that define cloud data ,applications services and infrastructure are given below: • Remotely hosted : Remotely hosted means data and services in cloud computing are hosted on remote infrastructure. • Ubiquitous : It means

One of the problems impacting the effectiveness of privacy policy is how
Cloud computing involves a lot of concepts and technologies. Companies and corporations such as Amazon, Google and Microsoft are providing services following the logic of computational infrastructure cloud computing, with Amazon the pioneer in providing and marketing infrastructure of this kind. The academic community has also shown interest in cloud computing, and some work has been directed to improvements in aspects of performance, security, usability, implementation and reliability of the system
