RAS (REMOTE ACCESS SERVICE) SERVER
RAS stands for Remote Access Service. The RAS server serves as a gateway that allows client networks to connect to the host server over a modem link.
To connect to a RAS server, either a Local Area Network (LAN) or a Wide Area Network (WAN) is used. In the RAS server, a Virtual Private Network (VPN) is used to support connection privacy.
The server remotely controls and checks users’ access to the host. Microsoft introduced the RAS server in the mid-1990s. It replaced the Routing and Remote Access Service (RRAS).
Security features of RAS
- Authentication protocols;
RAS tends to check the identity of users when they log on to the network. It verifies the user’s IP address and location status, and network type to access the server. This feature is very necessary because letting anyone log onto the server is an unwise choice.
- Encryption standards;
RAS uses encryptions to protect data in the server. RAS uses the advanced encryption standard to protect data sent over the server’s network.
- Security hosts;
RAS has security hosts that protect the users connected to the server from cyber spams.
- Point-to-Point Tunneling Protocol (PPTP);
This is a necessity for all servers, and RAS servers are not excluded. The PPTP is enveloped in the IP protocol. The PPTP is a protocol used by RAS servers to implement VPN.
It allows users to connect to the RAS server anywhere on the internet and still benefit from all the security features they would have if they connected or dialed into the server directly.
IAS (INTERNET AUTHENTICATION NETWORK) SERVER
The IAS server is an auxiliary server. It works inside with the RAS; all information and details of the user computer collected by RAS using authentication protocols are held in the IAS server.
The IAS server can also record each authentication request and response, client login time, client logoff time, and connection speed. The IAS follows the Remote Authentication Dial-in User Service (RADIUS).
While following this protocol, the IAS server can keep track of users’ connection time and limit user’s access to the server’s network according to their subscription. Microsoft also introduced the IAS server in 2003. IAS server was replaced by Network Policy Server (NPS) in 2008, but RADIUS is still used.
What are RAS and IAS servers? These are two different types of server that can be used for dial-up connections. They don’t need to be the same type of server, but they should offer the same qualities.
A RAS server is a type of remote access server. It facilitates dial-in connections from a remote location to another computer on the network using a telephone line as the connection.
This allows users at home or in an office other than the main company headquarters to connect and use resources that are located at that main company headquarters.
An IAS server is an internet authentication service, which provides authentication for Windows domain networks and their respective clients when they attempt to access information across public networks such as the Internet.
Two of the most important types of servers are RAS and IAS servers. What they do, how they work, what their purpose is – all these questions will be answered in this blog post.
RAS and IAS servers group by their function.
A Remote Access Server or RAS server is usually a part of the larger network and provides remote access to that network from anywhere in the world through dial-up connections, broadband, wireless technologies such as satellite internet.
An IAS server is an Internet Authentication Service that provides authentication for Windows domain networks and their respective clients when they attempt to access information across public networks such as the Internet.
– What do IAS servers do?
IAS servers authenticate users for Windows domain networks when they access information across public networks.
– What do RAS servers provide?
RAS servers usually provide remote access to a network from anywhere in the world through dial-up connections, broadband, and wireless technologies such as satellite internet.
IAS stands for Internet Authentication Service; it is an authentication service that authenticates users when a Windows domain network and its clients attempt to access information across public networks.
In contrast, RAS stands for Remote Access Service; it provides remote access to a network through dial-up connections, broadband or wireless technology such as satellite internet.
RAS servers typically provide the means of connecting from anywhere in the world while
