I am working on a university project where I am supposed to find out how to approach the following topic. I am not actually programming something, it is only a matter of working out a concept.
A company has set up sensor stations to send data to a server via an LTE connection. The server uses MongoDB. Due to the fact that most LTE connections provide dynamic IP adresses these stations never have the same IP adress.
This means that only the sensor station can access the server, but the server cannot access the sensor station - which is fine.
The stations must be able to down- and upload data, so I came across the option the set the IP binding to 0.0.0.0
I think this is the only option since the IP adresses randomly change.
The question now is what security measures are necessary to prevent unauthorized users from accessing the server.
The sensor stations have a computer build in that runs Windows, same as the server.
This is only a small side task of the project and therefore there is not so much time to deal with the topic intensively. When the system runs later, then of course more time is invested there.
Internet security is definitely not my speciality and this is only about getting a rough overview on what we will have to deal with later.
Thanks for the help
