  endpointSelector:
    matchLabels:
      app: redis
  ingress:
  - fromEndpoints:
    - matchLabels:
        app: frontend
    toPorts:
    - ports:
      - port: "6379"
        protocol: TCP

This policy allows only the 'frontend' application to interface with the 'redis' application using the TCP port 6379.

Delving into Calico's Safety Aspects

Contrarily, Calico harnesses a conventional IP-based security mechanism. It facilitates the creation of network policy capable of managing traffic based on IP addresses, ports, and protocols. While this method might lack the detailed control of Cilium's identity-based model, it provides familiar territory to many network managers.

Calico also advocates for the utilization of network sets, basically specified clusters of IP addresses or subnets. These sets help in implementing policies applicable to a set of interconnected endpoints, thus easing the control of complex network configurations.

Here's a sample of a Calico network policy:

 
apiVersion: projectcalico.org/v3
kind: NetworkPolicy
metadata:
  name: allow-tcp-6379
spec:
  selector: app == 'redis'
  ingress:
  - action: Allow
    protocol: TCP
    source:
      selector: app == 'frontend'
    destination:
      ports:
      - 6379

This policy corresponds to the Cilium's policy shown above, allowing only the 'frontend' application to engage with the 'redis' application using the TCP port 6379.
