For example, if you want to explicitly deny wireless access to the members of a Windows group, you can create a network policy that specifies the group, the wireless connection method, and that has a policy type setting of Deny access. Determine whether you want NPS to ignore the dial-in properties of user accounts that are members of the group on which the policy is based.
When this setting is not enabled, the dial-in properties of user accounts override settings that are configured in network policies. For example, if a network policy is configured that grants access to a user but the dial-in properties of the user account for that user are set to deny access, the user is denied access.
But if you enable the policy type setting Ignore user account dial-in properties, the same user is granted access to the network. Determine whether the policy uses the policy source setting. This setting allows you to easily specify a source for all access requests. Alternatively, you can specify a vendor-specific source.
Determine the settings that are applied if the conditions of the network policy are matched by the connection request. Recording user authentication and accounting requests in log files is used primarily for connection analysis and billing purposes, and is also useful as a security investigation tool, providing you with a method for tracking the activity of a malicious user after an attack.
Choose the type of information that you want to log. You can log accounting requests, authentication requests, and periodic status. Design your log file backup solution. The hard disk location where you store your log files should be a location that allows you to easily back up your data.
In addition, the hard disk location should be protected by configuring the access control list ACL for the folder where the log files are stored. Determine the frequency at which you want new log files to be created.
If you want log files to be created based on the file size, determine the maximum file size allowed before a new log file is created by NPS. Determine whether you want NPS to delete older log files if the hard disk runs out of storage space. Determine the application or applications that you want to use to view accounting data and produce reports. NPS SQL Server logging is used when you need session state information, for report creation and data analysis purposes, and to centralize and simplify management of your accounting data.
Determine whether you or another member of your organization has SQL Server or SQL Server relational database development experience and you understand how to use these products to create, modify, administer, and manage SQL Server databases. Plan to use network access servers that send the Class attribute in all accounting-requests. If the Class attribute is sent by the network access server in the accounting request messages, it can be used to match the accounting and authentication records.
This procedure provides general guidelines about the settings you should use to configure your NASs; for specific instructions on how to configure the device you are deploying on your network, see your NAS product documentation.

If the connection request does not match the Proxy policy but does match the default connection request policy, NPS processes the connection request on the local server.
If the connection request does not match either policy, it is discarded. Although accounting messages are forwarded, authentication and authorization messages are not forwarded, and the local NPS performs these functions for the local domain and all trusted domains.
With standard configuration, wizards are provided to help you configure NPS for the following scenarios:. To configure NPS using a wizard, open the NPS console, select one of the preceding scenarios, and then click the link that opens the wizard.
To configure NPS by using advanced configuration, open the NPS console, and then click the arrow next to Advanced Configuration to expand this section. To configure NPS logging, you must configure which events you want logged and viewed with Event Viewer, and then determine which other information you want to log. In addition, you must decide whether you want to log user authentication and accounting information to text log files stored on the local computer or to a SQL Server database on either the local computer or a remote computer.

They are simply two different protocols. Over time, LDAP has grown increasingly untenable as an authentication protocol due to its reliance on insecure credentials and ties to legacy on-premise equipment. Merit Network, a nonprofit organization that provides quality networking services to educational, government, and healthcare entities, requested a solution that condensed their authentication, authorization, and accounting systems.
Initially, RADIUS primarily supported credential-based authentication, but it has changed over time to support other authentication methods such as digital certificates. This keeps it relevant within the scope of the ever-changing cybersecurity industry. When it comes to anything in the tech industry, change happens fast. Some replacements have been suggested, such as the Diameter protocol another AAA protocol , but these days, Diameter is used mostly in 3G.
Numerous companies, from massive enterprise-level organizations to small businesses, have integrated RADIUS servers with their infrastructure. It can have a devastating impact both to your daily operations and to your reputation with customers and clients.
