Smartlink, as it works today has extremely limited capabilities with regard to administration and security. Those would be as follows:
#1) No Access Log: Currently, the only indication a 6400M owner has of someone accessing their radio is a brief pop up message stating a client with an IP address of xxxx.xxxx.xxxx.xxxx has connected to the 6400M. I understand it would be possible to use the SmartSDR API to collect remote access user information and create a log. I feel this is a much needed feature.
#2) Account Administration: The current account administration is very basic. The account in Smartlink is tied to a owners email address. Once an account is created there is no account management tool. So, if an account is compromised the only option a owner has is to say they forgot their password. This allows the owner to change the password. This is not really account administration. The other issue is once you create an account there is no way for the owner to delete it to my knowledge. Finally if you want to share your 6400M with your friends but you don't want them to use your email address and password the only option you have is to create a new account with a different email address and password.
