Networking
The Networking group covers entries related to network infrastructure, connectivity, and traffic management. This includes virtual networks, subnets, load balancing, DNS, routing, peering, and network-level access controls.
CCC.VPC.CN01 Restrict Default Network Creation
Objective
Restrict the automatic creation of default virtual networks and related resources during subscription initialization to avoid insecure default configurations and enforce custom network policies.
Assessment requirements
When a subscription is created, the subscription MUST NOT contain default network resources.
Applicability: tlp-amber, tlp-red

CCC.VPC.CN02 Limit Resource Creation in Public Subnet
Objective
Restrict the creation of resources in the public subnet with direct access to the internet to minimize attack surfaces.
Assessment requirements
When a resource is created in a public subnet, that resource MUST NOT be assigned an external IP address by default.
Applicability: tlp-red

CCC.VPC.CN03 Restrict VPC Peering to Authorized Accounts
Objective
Ensure VPC peering connections are only established with explicitly authorized destinations to limit network exposure and enforce boundary controls.
Assessment requirements
When a VPC peering connection is requested, the service MUST prevent connections from VPCs that are not explicitly allowed.
Applicability: tlp-green, tlp-amber, tlp-red

Observability
The Observability group covers entries related to logging, monitoring, metrics, alerting, and event publication. This includes audit trail integrity, enumeration detection, and protection against tampering or unauthorized access to operational telemetry.
CCC.VPC.CN04 Enforce VPC Flow Logs on VPCs
Objective
Ensure VPCs are configured with flow logs enabled to capture traffic information.
Assessment requirements
When any network traffic goes to or from an interface in the VPC, the service MUST capture and log all relevant information.
Applicability: tlp-amber, tlp-red
