CCS/CC3220SF: questions about the CC3220SF protection

Hi Alvaro,

Q1.- For example,
the CC3220SF has protection so the firmware cannot be cloned from the MCU or via WiFI? If so, what is it and how is activated that protection.

I think you will find this document helpful. Specifically for this question section 3 which talks about file system security. Many of these features don't have to be activated as they're enabled by default and implemented in the secure boot loader. 

Q2.When the CC3220SF is connected to WiFi, what security protocoles or codes I can use (or the MCU has) for preventing that someone connects to the MCU WiFi network?

Are you connecting your device to an access point? If so it's important your router supports standard security features like WPA2 so that the connection between the your device and home network is secured. Similarly if the CC3220 is going to be communicating with an external server we support secure sockets so you can also encrypt your connection if you're going to be communicating with your machines outside of your local network. More details in section 2 of the document I linked above.

Q3.My device is going to control a Garage door openner to open and close the door via an App, what security protocoles or codes are used on the MCU to prevent someone from hacking the network or the App and control de Garage Door openner?

Same answer as Q2.

Q4.If someone buys my device, how can I protect the code so it cannot be clonned,read or extracted from de MCU?

Similar to my answer to Q1. I would add here that production mode images block the JTAG interface and access to individual files. More info in section 4 of the document I linked above.

Hope this helps. To get a better understanding of our security offering I would recommend you read through the document I linked. If you have any follow up questions let me know here.
