What Are Network Authentication Protocols?
Let’s assume that there is a single administrator present who wants to access hunted routers and for simplicity let’s also assume that the local database of the device is the database that is to be used for the authentication or password what this means is that the administrator will have to make same user accounts for many times this is not a problem but if he wants to keep different password as well as different user name for each of the user then it will become hectic task because he will have to do it manually for each of the devices, to make this process more easy and convenient access control server is used which provides a centralized management system and in this all the password and usernames are stored there are many two protocols which are used by the acs with the help of clients to serve this purpose:
- RADIUS
- TACAS+
So let’s understand each of these protocols:
Network Authentication Protocols: RADIUS, TACACS+
Network authentication protocols are known as methods that are used to verify the identity of the users or the devices that are written to access a particular network. these protocols are used to make sure that only the authorized users of the devices are granted access while making sure the unauthorized users are out. so in this article, we will understand two of the most commonly known protocols used for network authentication: RADIUS & TACAS+
