For more details on what runs on what host, look to AniNIX/Ubiqtorate, particularly the playbooks/deploy.yml file, and the network traffic captured in AniNIX/Sharingan.
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.
