If a camera is obscured you send a meat body to investigate the cause.
As for deterrent systems, why use expensive wiles tec that can be easily interfered with. The wireless systems today are actually far more secure because of there simplicity. The control panel can not be controlled by the radio system, it only listens for a couple of signals typically all clear, alarm and system fault. Anything else is ignored the best a warless hacker could hop to achieve is spoofing the all clear signal, you couldn’t use the warless interface for the camera to open a door. In SR3 it seems to be preserved that there are lots of placed you can interface your cyber deck to control the security system, EG a door panel. Personally if I was designing a door panel connected to a central security network it would not be an access point. The door panel would have 2 wires leading to the computer port witch would receive a binary signal from the panel. Any binary signal received would be compared to the access codes on record and another code would not be considered for 5 seconds. 5 incorrect codes and you send out a meet guard. Suddenly sequencers and panel tampering are all but useless because you don’t have access to the processors. Even on a warless system you can do this. A camera sends an encrypted video feed, it receives encrypted data on witch way to point, its programming will interpret any other information as garbage. But apparently once you have small cheep computers controlling security aserts you have to accept that they will be hacked rather than programming them for a specific task and ignore any other data.

Not if it is a successful Physical illusion.
If you are talking about RL house security, as far as i've been able to determine the wireless sensors are only polled every so many minutes (to conserve batteries). If the main control unit receives back a "I'm sensor #x, and I'm ok" as a response then that is good enough. If you were able to initially time it precisely to jam an alarm signal from the sensor, then smash the sensor, and then spoof the sensor replying to the polling then you've beat it. Of course if you knew the physical location of the system components it'd be easier to just break in, run to the central system, and disable that (through brute force) before the passcode timeout.
In SR devices are all assumed intellegent to some extent, and capable of passing data packets around. *shrug* You know "the toaster has an IP" dream. The theory is that once you get on this constantly humming stream of data, with good enough hardware/software/skills you can slip in unnoticed data/code (they are pretty much one and the same in SR computing) that can subvert the functioning of devices and the host. Of course you can try dream up all sorts of changes to this and that to make the system super secure. But remember SR is a game, not a simulation. It's like someone going in to a movie like Ocean's Twelve and expecting the plot to be intellectually deep and logical. :P Don't over think it, it'll just hurt your head.
Ya, theoritically as a system increases in computational power and abilities it also tends to increase in complexity, and along with that the range of possibilities of being made to do something initially unintended ("hacked"). |

The part of SR hacking that really annoys me is encryption.
A rating 12 encryption system (about the best you can get) can be beaten buy a competent Decker with a rating 6 decrypt utility in a matter of minutes. Compare this to today where consumer encryption products take days or months for a super computer to crack and if America can crack there own encryption cods within a couple of years (with the benefit of knowing how the system worked) they commission a new encryption program.

Ya, that part really bugs me too. But it helps to think of decrypt utility as more of a set of kiddie scripts that try to exploit software defects and backdoors secretly planted by manufacturers and/or governement agencies. The higher the rating the more they know the better chance they find one that that particular encryption is vulnerable too. Likewise higher rated encryption has fewer flaws and/or harder to exploit flaws for decryption attempt to match up with and exploit. It's not a perfect concept, but I find it more paletable than assuming whatever the 2064 equivalent of 128-bit RSA is can be cracked by brute force in seconds with the equivalent of a current day PC. |

Aren't there codes today that have yet to be officially cracked?
As in, if they have been those responsible ain't talking about it. That and Broadcast encryption is statistically difficult to break in SR3 as is, from everything I've read. 1, you can't record and crack later, must be done live. 2, a rating 3 broadcast encryption system foils most rating 6 decryption based on the rules. |

Shhhhhhhhhhhh *points to a sign that reads "No talking. Belief suspension in progress."*
I forget how it shakes out, but it is horrendously expensive on both sides. I'll look it up now.... |

if I recall correctly broadcast encryption is an apposed rating test. 3 dice target 6 and 6 dice target 3 I think the decrypt will win. And even if you don’t you can try again.
The no recording also doesn’t make sense. It dose for rigger encryption because cracking that involves sending signals and influencing there system but for standard radio cams you should be able to record it. Edward |
