Hacking question! Options

[psionghost]

Just a quick question on hacking, when your hacking on the fly you use your hacking + exploit against (firewall, 1 CT) Extended Test mod'd vs sec or admin level access right?

Also, it says the system gets a free, Analyze + Firewall (stealth) to be detected? so is that your basic stealth rating only or is your hacking skill involved as well too? If you brute force your way in on the first round does the system still get to run that check?

Im just wondering if any other modifier applies?

Just seems that, In my book the 5th printing corrected of the BBB.

That the system is running an opposed extended test against you vs only your stealth to detect you? Say im breaking into a system and i want sec access vs a high level system = Character would roll Hacking 6 + Exploit 6 vs (6 + 3 sec access = 9) Extended Test.

And the system would roll Analyze 6 + firewall 6 vs my stealth of (6)?

So nothing i can do increase my chance of staying hiding when hacking on the fly? or am i reading it wrong and i get to roll stealth plus another dice pool?

please help.
