2a) slow probe: Hacking+exploit (system+firewall+level of access modifier, 1 hour)
2b) Hacking on the Fly: Hacking+exploit(system+firewall+level of access modifier, complex action), vs System+firewall(Your Stealth Rating, complex action)
3) Log in: System+firewall(stealth rating), Any IC does Agent+Analyze(stealth rating)
Slow Probe is an Extended Test Exploit+Hacking (System+Firewall+Access level, 1 hour). When entering the node, the node gets a free Test Analyze+Firewall (Stealth).
Hacking on the Fly is an Extended Test Exploit+Hacking (System+Firewall+Access level, Complex Action). When making a test, the node gets a free Extended Test Analyze+Firewall (Stealth, hacker making a test).
When logging in, any IC can possibly spend a Simple Action to make a Matrix Perception Test. If you're running a Stealth program, that's an Opposed Test, Analyze+IC Rating versus Stealth+Hacking. With one net hit, the IC can get the programs run by your persona, and should trigger an alert if Stealth or Exploit runs.
