Problem with this: keep your phone with you always conflicts with don’t have secure conversations within mic range of your phone. You can’t do both of these.

But otherwise this is great and I would probably add “reset and replace devices often.”

The rooms where you can have secure conversations will have a bank of tiny lockers outside the door for phones/keys.

Are lockers really that secure? Similar documents advise against leaving laptops in hotel rooms or cars, even if locked, because they are easy to get into. I imagine a locker is not hard to break into. Small locks can be picked in a second or two by people with practice, which does not look different than retrieving your own phone.

The lockers are just so you have a place to put your phone. They are not secure in any way. Using a keyed locker just ensures you don't pick up someone else's phone by accident after the meeting. Remember that secure rooms live inside secure buildings, usually inside a secure facility with a fence and guy standing at the gate. And the guy has a gun.

It also prevents casual but intentional unauthorized access, just not a determined attacker.

As you note, there are other layers of security for that.

Usually, but not always. I've been to rooms that don't have this and there's just a pile of phones sitting outside.

We have lockers to secure phones when you can't take them with you.

It's prohibited to bring phones into places where you will have these kind of conversations
