What is the protocol used to control access to network resources?
RADIUS is protocol used for controlling access to network resources by authenticating, authorizing, and accounting for access, and is referred to as an AAA protocol. RADIUS is the unofficial industry standard for this type of access. It is more common today than ever before, being employed by ISPs, large corporations that need to manage access to the Internet, and also internal networks that operate across a large variety of access providing technologies such as modems, DSL, wireless and VPNs. To better understand what RADIUS does, let's try to understand each of its required functions as an AAA protocol.
What is rhosts file?
The rhosts file is one of the “remote authentication” databases for the rsh program. It specifies remote hosts and users that are considered trusted. Only trusted users logged on to a trusted remote host are allowed to access the local system. These users must have userids on the local system.
What is a remote authentication dial in user service?
The remote authentication dial in user service (RADIUS) protocol is a third-party authentication system. RADIUS is described in RFCs 2865 and 2866, and it uses the UDP ports 1812 (authentication) and 1813 (accounting). RADIUS formerly used the unofficially assigned ports of 1645 and 1646 for the same respective purposes, and some implementations continue to use those ports.
How does trust pass authentication requests?
How a specific trust passes authentication requests depends on how it is configured; trust relationships can be one way, providing access from the trusted domain to resources in the trusting domain, or two way, providing access from each domain to resources in the other domain . Trusts are also either nontransitive, in which case trust exists only between the two trust partner domains, or transitive, in which case trust automatically extends to any other domains that either of the partners trusts.
What is a taccs?
The Terminal Access Controller Access Control System (TACACS) is a centralized access control system that requires users to send an ID and static (reusable) password for authentication.

What is authentication in NAS?
Authentication The server seeking access sends a request to NAS. The NAS then creates and sends a RADIUS Access Request to the RADIUS Server. This request acts as an authorization to grant access. Typically, a user name and password or some other means of establishing identity is requested for this process, which must then be provided by the user seeking access. The request will also contain other means of verification that the NAS collected, such as physical location of the user and/or the phone number or network address of the user.

Hyper-V Manager lets you manage a small number of Hyper-V hosts, both remote and local. It's installed when you install the Hyper-V Management Tools, which you can do either through a full Hyper-V installation or a tools-only installation. Doing a tools-only installation means you can use the tools on computers that don't meet the hardware requirements to host Hyper-V. For details about hardware for Hyper-V hosts, see System requirements.

Purpose
Specifies remote users that can use a local user account on a network.
Description
The $HOME/.rhosts file defines which remote hosts (computers on a network) can invoke certain commands on the local host without supplying a password. This file is a hidden file in the local user's home directory and must be owned by the local user.

What is SSH for?
You typically use SSH to allow users to log in to a remote host and execute commands. However, SSH also supports tunneling and X11 connections. It can even transfer files using SFTP or SCP. SSH is applicable for numerous applications within most common platforms, including Linux, UNIX, Windows, and Apple® OS X, although some applications may require features that are only available or compatible with specific SSH clients or servers.
What is the connection layer?
The connection layer defines channels, global requests, and the channel requests through which SSH services are provided. A single SSH connection can host multiple channels concurrently, each transferring data in both directions. Channel requests relay information such as the exit code of a server-side process. The SSH client initiates a request to forward a server-side port.
What is SSH encryption?
Secure Shell (SSH) was intended and designed to afford the greatest protection when remotely accessing another host over the network. It encrypts the network exchange by providing better authentication facilities as well as features such as Secure Copy (SCP), Secure File Transfer Protocol (SFTP), X session forwarding, and port forwarding to increase the security of other insecure protocols. Various types of encryption are available, ranging from 512-bit encryption to as high as 32768 bits, inclusive of ciphers, like Blowfish, Triple DES, CAST-128, Advanced Encryption Scheme (AES), and ARCFOUR. Higher-bit encryption configurations come at a cost of greater network bandwidth use. Figure 1 and Figure 2 show how easily a telnet session can be casually viewed by anyone on the network using a network-sniffing application such as Wireshark.
What is transport layer protocol?
Transport Layer Protocol: This protocol accommodates server authentication, privacy, and integrity with perfect forward privacy. This layer can provide optional compression and is run over a TCP/IP connection but can also be used on top of any other dependable data stream.
