Technical protection of information?

Question

Information Security

good afternoon!
During a discussion with a friend, a question arose. Became interesting.
Here is the company Elon Musk, which creates engines. For example, they have finished and are now being tested on a bench indoors. How do they protect, for example , engine life . I'm only interested in protection options TECHNICAL. All sorts of documentation, conversations between employees, torture - they are not interested.

For example, if we wanted to hide the brand, we would have to at least hang curtains during production. So that they don’t get pointers through the windows ..

As I understand it, you can:
1) also curtain (only when testing) so that you don’t see the test results
2) look for embedded devices
3) make noise in the room to mask the sounds of an engine that is running
4) create false vibrations of an engine that is running..
give me ideas or rebut my points, if not, please!!

Answer 1

the legal department protects, as well as contracts on contracts,
how will the test sound of an electric motor help competitors? what for to protect him if we allow the entrance to the laboratory with passes and the cameras record visitors?

Answer 2

Since you know what technical protection is, then you have read a book on this topic. Accordingly, there are 2 channels: PEMIN, vibro-acoustics. Do not forget to hang the vibrator on the glass, otherwise they consider the vibration to be a laser.
But it's better to steal a 3D engine model than to try to steal a 3D model by sound. Do not believe in technical protection if you do not have an informatization object with GT. It's easier to go through the Internet or bribe the engine developer on linked.
