IC Armies, Hackability of nodes Options

[Gelare]

So here's the thing. You have this node with let's say, for sake of argument, all 4's. It's got all sorts of valuable paydata on it, so of course you want to protect it. So you buy an IC program, as well as attack, armor, analyze, trace, all that good stuff, all at rating 4. You want this IC to start defending, so you boot up the IC program, boot up armor and analyze. This is three programs running, all good. A system with all 4's should be a bit challenging, but nothing a good hacker can't handle, right?

You're paranoid, so you set the IC, an agent, to automatically run analyze every so often to scan for intruders. How often can it do this? As an agent, it gets three IP's in the matrix, so presumably it can run analyze every IP. Since hackers oppose with hacking+stealth, it seems like no hacker would be able to go undetected for longer than a combat turn or two.

Now comes the really iffy part. You have this IC running, along with analyze and attack. You want to have a lot of security in case someone breaks in though, so you hit ctrl+c and ctrl+v and poof! New IC program! So now you have two security agents! Let's further say you don't mind about reducing the response a bit, so poof, poof, poof, now you have five agents, two other programs, making the node's response 3, but who cares! You have five agents running, with analyze actions happening once every 0.2 seconds on average. And when something does get detected, heavens help it, it's gonna get slammed with attack actions out the wazoo. Obviously, if the node has even better hardware, it gets straight up ridiculous.

My biggest question is, if people have IC, why don't they just always run as many copies of it as they can without reducing response? When one gets crashed, or if a program gets crashed, why doesn't the node immediately restart the program as a complex action? Why doesn't a corporation get their resident software guy to code one rating 6 IC and then copy it a bajillion times for all the security needs?

Thanks for the help, all.
