But as the remote access will be available by using an IP address therefore it is possible that an unauthorized user can take access using that same IP address therefore for security measures, we have to put authentication. Also, the packets exchange between the devices should be encrypted so that any other person should not be able to capture that sensitive information. Therefore, a framework called AAA is used to provide that extra level of security. AAA Authentication Authentica...
