ITU... as in Internationnal Union of Telecommunications
Basically the Telecom kit vendor and Telecom operator union... so that long ago all the country operators had protocols to talk to each other.
They went for a broader range, but that's still at the heart a standardization body, not an expert group on cybersecurity.
( even if they did branch out in that domain along with a few other )
Biting the hand that feeds IT
