# Standards and References - Kubernetes Network Policy with Calico
|
|
|
|
## Industry Standards
|
|
|
|
### NIST SP 800-190: Application Container Security Guide
|
|
- Section 4.4: Container Networking - Isolate container network traffic using network policies
|
|
- Section 5.3: Network Security - Implement micro-segmentation between containers
|
|
- Recommends default-deny policies with explicit allowlisting
|
|
|
|
### CIS Kubernetes Benchmark v1.8
|
|
- 5.3.1: Ensure that the CNI in use supports Network Policies
|
|
- 5.3.2: Ensure that all Namespaces have Network Policies defined
|
|
- 5.3.3: Ensure that the default namespace does not contain any pods
|
|
|
|
### NIST SP 800-53 Rev 5
|
|
- SC-7: Boundary Protection - Implement network segmentation controls
|
|
- AC-4: Information Flow Enforcement - Control network traffic between pods
|
|
- SC-7(5): Deny by Default / Allow by Exception
|
|
|
|
### NSA/CISA Kubernetes Hardening Guide v1.2
|
|
- Section 3: Network Separation and Hardening
|
|
- Use network policies to isolate workloads
|
|
- Implement default deny ingress and egress policies
|
|
- Limit pod-to-pod communication to minimum required
|
|
|

## Zero Trust Network Model
|
|
|
|
### Principles Applied
|
|
1. **Never trust, always verify** - Default deny all traffic between pods
|
|
2. **Least privilege access** - Only allow specific required communication paths
|
|
3. **Micro-segmentation** - Isolate workloads at pod-to-pod granularity
|
|
4. **Identity-based policies** - Use service accounts and labels for policy selection
|
|
5. **Continuous monitoring** - Log and alert on denied traffic patterns
|
|
|
|
## Compliance Mappings
|
|
|
|
### PCI DSS v4.0
|
|
- Requirement 1.2.1: Restrict inbound and outbound traffic to that which is necessary
|
|
- Requirement 1.3.1: Inbound traffic is restricted to that which is necessary
|
|
- Requirement 1.3.2: Outbound traffic is restricted to that which is necessary
|
|
|
|
### SOC 2 Type II
|
|
- CC6.1: Logical access security - Network isolation between components
|
|
- CC6.6: Network boundaries - Restrict access at network boundaries
|
|
|
|
### HIPAA
|
|
- 164.312(e)(1): Transmission Security - Protect data in transit between services
|
