1. Why We Need This Use Case

This use case is essential for enhancing application security and network management by restricting network traffic to specific ports within an application. This approach is particularly valuable for applications that expose multiple services on different ports, allowing precise control over which services are accessible to other pods or external clients.

2. When We Need This Use Case

  • Enhanced Security: When parts of an application should not be exposed to all consuming services or pods, enhancing the security by limiting potential attack vectors.

  • Resource Management: To prevent unnecessary access to resource-intensive services that might be running on specific ports.

  • Compliance Requirements: In environments where regulatory compliance dictates that only certain types of traffic are allowed for specific services.

  • Selective Connectivity: For applications that require selective interaction with other services, such as monitoring tools or health checks.
