drones, Building security and riggers and struggles for control Options

[Hat]

Greetings,

In SR3 a rigger was quite distinct from a decker and that was fine. I understand that the rules are a lot more integrated now and that anyone can use drones, np. I am curious though about whether a security rigger should have to be a full blown hacker and then add additional rigging skills on top of it (electronics, hardware, pilot, mechanics...).

What's confusing is how jumping into a building is supposed to work.

How many subscribed devices does a building count as?
What's the system and response that control and are impacted?
Do you have to have Cybercombat and a host of programs to ensure that you're not challenged for control? Is there a simpler mechanism for control?

On a related topic, if a Rigger is jumped into a drone and someone else attempts to hack into it, how is that resolved?

How have GMs worked through this in their own campaigns?

Thanks!

With a sweep of his...
