Install Radius Server 2008 R2 – Managing Network Devices How to configure Network Device Management with RADIUS authentication using Windows NPS to authenticate SSH connections?
Technologies used in today’s scenario to implement RADIUS authenticated network device management using Windows NPS are as follows;

You’ve heard many say that AAA is the best security model for user access and network device management. As a good professional practice, securing network devices using the Triple A process is consistent with many of today’s security best practices.

Authentication is the first process that provides a way to identify a user, but requires access to a network resource, usually requiring the user to enter a valid username and password before gaining access. The authentication process is based on each user requiring authorization with a unique set of criteria to obtain the correct access. The AAA server, which in our case is Microsoft Network Policy Server, compares the user’s identity data with the user’s credentials stored in a database, which in our case is Windows Active Directory. If the credentials match, the user is granted access to the network. If the credentials are different, authentication will fail and network access will be denied.
Now, after the user successfully completes the authentication, the user should be allowed to perform certain tasks. After logging into a network device, for example, a user may attempt to issue commands. The authorization process determines whether the user is authorized to issue such commands. Authorization is simply the process of enforcing policies: determining what types and qualities of actions, resources, or services a user is allowed to perform. Authorization usually occurs in the context of authentication. Once a user is authenticated, they can be authorized for various types of access or actions.
The last part in AAA is metering, which measures the resources a user consumes during access. This may include the amount of system time or the amount of data sent and/or received by the user during the session. Accounting is performed by logging session statistics and usage information and is used for authorization control, billing, trend analysis, resource usage, and power planning activities.
Authentication, authorization, and accounting services are often provided by a dedicated AAA server, a program that performs these functions. The current standard for network access servers to communicate with the AAA server is Remote Dial-In User Authentication Service (RADIUS), for which we used a Microsoft NS server in our application.

Then create a new authentication policy under Network Policies. Enter a name for it, such as Network Switch Authentication Policy for Network Administrators. Make two conditions: first, specify a domain group whose members can be authenticated in Windows groups (in our example, the network administrator accounts are in the AD Network Admins group). The second condition, authentication type, is to select PAP as the authentication protocol.
In the vendor related section, you need to add to the Cisco-AV pair for the router to go to privilege level 15, if you add “shell:priv-lvl=15” to Cisco-AV, select the following.
PS: the following command makes everything work without it; you will get below error message; You do not need to provide a RADIUS name every time you enter a wired or wireless authentication server. RADIUS, commonly known as AAA servers, perform the primary task of authentication, accounting, and authorization in the 802.1x infrastructure. In fact, as the owner, Microsoft has evolved its RADIUS server over time to meet the authentication needs of its customers.
When it comes to the evolution of Windows Server, the 2008 edition holds an important place in history. Although rarely used now, we thought it would be a good time to help existing Windows 2008 Server customers install them. But as you know, most of these servers are local and attract the attention of hackers.

Here’s a recent case of an update causing an authentication error, mostly affecting local settings. But we’re not here to judge local servers; we’ll leave it to you. Let’s go back to installing Windows 2008 Server forever.
Before you configure Windows Server 2008, ensure that you meet the following requirements to successfully configure Windows Server 2008.
Network compatibility can be checked using the Microsoft Application Compatibility Toolkit (ACT), now called Windows Analytics.
You can use the Network Policy Wizard to create and add new conditions, restrictions, and settings to a network policy.
Administering Windows Server Question Answer.
Administrators can define and implement a wide range of policies using cloud RADIUS during search policies. For example, depending on the time of day, you can decide whether or not to accept people and devices. You can also restrict access to devices running a specific operating system.
Traditional on-premises RADIUS servers are prone to several security flaws and vulnerabilities. On-premise infrastructure typically uses Windows RADIUS servers built with NPS, which have many vulnerabilities that are often exploited by hackers in zero-day attacks. Moreover, it takes a lot of time and experience to make them.
In addition, due to its physical accessibility, having an NPS server on-premises makes it vulnerable to various physical security threats, from intruders to disasters or simply power outages. Given the costs of maintaining highly secure physical locations, there are rare cases where an on-premises service is cheaper than cloud-based RADIUS.
Somewhat counterintuitively, cloud networks tend to be much better secured and more resilient than their on-premises counterparts, largely due to economies of scale.

Designed for on-premise AD environments, NPS has significant disadvantages when integrating with other Microsoft cloud products such as Azure AD. If you want to use Azure with NPS, you need to use a different authentication server or proxy to simplify the process. These procedures are not only time-consuming and complex, but also very expensive in nature.
Windows Server 2008 has been the go-to tool for network administrators for many years and has seen the evolution of almost the entire Microsoft ecosystem. But it is difficult to ignore its shortcomings, which have become more of a safety factor than an advantage these days. Windows Server 2008 has struggled to keep up with the evolution of the cloud, so think it’s time to retire and upgrade your 15-year-old server for network security.
Moving to the cloud has huge benefits in an on-premises world full of security threats, and what better way than using our innovative Cloud RADIUS! You can eliminate almost all of these disadvantages by using a cloud server such as Cloud RADIUS Support.
Cloud RADIUS powered by advanced policy engines gives you the ability to deny/allow access to users based on multiple attributes such as user/device attributes or even time of day. Additionally, our cloud RADIUS is designed to be vendor neutral, so you can use it with any IDP. Using its servers, you can enforce policies with real-time user lookups against Azure, Okta, and Google Workspace.

In addition to requiring no time-consuming setup, Cloud RADIUS is resilient to local risks such as failures and thieves. You don’t need to install it at every location in your company because it’s hosted in the cloud and has a built-in backup feature.
