Security for IOT project?



i’ve done IOT project but it’s not very secure.

Currently devices send data to main server and it works fine, but someone could (if they new server IP) send false data.
I want to prevent this.

How is security done in IOT?
How do u know that device that is sending data is legit?

Could you point me to resources, examples or experiences that would help me solve this issue?

Thank you
