Have you looked at Node Red and the node-red-contrib-alexa-remote2-applestrudel pallet? It can do a lot of things based on what you say to Alexa and can even know which Alexa you are speaking to. For example, in any of my rooms that I have a ceiling fan and an Alexa, I can say "It's hot in here" and it will turn on the fan in the room I am in without telling her which room.
In your example, it could listen for the Codeword you referenced and only continue the Node Red Flow if you say the code. If you know regex, you could probably get pretty complex. I don't.
If you keep reading in that thread, @Royski does some cool things w/ this method.
EDIT: As an example to solve this:
You could create a Node Red flow that listens for you to say "Alexa, [Codeword] give me security update". The flow would then go thru each device you specify and to see if it is open/closed/active/inactive and Alexa could respond with something like the following: "The following motion sensors are active. Front Door -> Back Door -> Garage Door......."
