Cauldron Network Defences

Base Encryption: It's just PGP, only upgraded to quantum computing levels (16384 qbit) and with a lot of the holes patched out - the Key for the network has to be manually enterred into each Agent's device of choice by an unnetworked machine in each Cauldron location. This is manually enterred only by The Black Signal.

Defences: Any incoming connection is checked by one of the ball of spiders. If it's unknown, a Private Key request is sent. Responding with an incorrect Private Key gets you a whole wall of counterhacking disguised as a loading bar, as well as a fuckton of viruses of all varieties - mostly Black ICE, as those are most likely to fry the machine. Every connection is also WAF Fingerprinted, allowing for an Application Layer Firewall to be implemented. This helps stop the injection of viruses and trojan horse programs and the like, though despite the fact that a nigh-infinite ball of cyber spiders is continually updating the allowed and disallowed (mostly the latter) list, it cannot completely block all possible harmful data streams.

Exact Connection: Based on IPv6, and each version of the IP is only given out encrypted, can only be viewed encrypted and is only decrypted with a Private Key generated once for each instance of the software then promptly stored only in the unnetworked machine. This is manually enterred only by The Black Signal.

Net Effect: It's the equivalent of an airtight safe with a one-of-a-kind locking mechanism that's been burried somewhere in mainland Europe, and that's all the info you have to go on. It's secure.
