Access layout looks something like the below: ``` Internet └── Shadowfeed ├<> 10.0.1.0 │   ├── Core ^   │   ├── Darknet │   │   ├── Geth-Hub-N │   │   ├── Maat │   │   ├── MaatBuilder │   │   └── Sharingan │   └── Nazara ├── 10.0.2.0 │   ├── Chamberlain ^   ├── iRobot │   └── Nest └── 10.0.3.0 ├── Games ├── Tachikoma └── Tricorder ``` For more details on what runs on what host, look to [AniNIX/Ubiqtorate](/AniNIX/Ubiqtorate), particularly the `playbooks/deploy.yml` file, and the network traffic captured in [AniNIX/Sharingan](https://sharingan.aninix.net/). The general idea here is thus: * 10.0.1.0/24 is the service subnet, with NAT access from Shadowfeed creating a pseudo-secured DMZ for other AniNIX-controlled machines. * SSH and HTTPS access is then filtered through the NAT controls -- typically, traffic passes through Core to ensure the right security headers get set and only the approved applications get accessed. * This also assists in letting Core's network IDS and IPS capture threat data for Sharingan. * It also assists in that * 10.0.2.0/24 is the vendor subnet -- machines here get external access but no access to any host not themselves in 10.0.0.0/8. * 10.0.3.0/24 is the user subnet -- machines here can access the external world and 10.0.1.0/24 but not 10.0.2.0/24. Ideally, only the following external ports are open: * 22/tcp/ssh to Core, for read-write access * 443/tcp/https to Core, for read-only access * 6697/tcp/ircs to Core, for communication access * Some external NAT port for bastion access to Nazara. This ideal isn't currently met, due to some application limitations, but we're working on it.
