Ports exposed

No TCP/UDP Ports Exposed

Not exposing any TCP/UDP ports during the initial stage of a service or container deployment is a security measure that limits network access.

Impact

  1. Reduced attack surface: Minimizes potential entry points) for network-based attacks.
  2. Improved security posture: Prevents unauthorized access to services that may not be fully configured or secured.
  3. Network isolation: The service cannot receive incoming connections, limiting its ability to interact with other network entities.
  4. Outbound connections: While incoming connections are blocked, the service can still initiate outbound connections if needed.

Considerations

  1. Service accessibility: Services requiring incoming connections will require port exposure at a later stage.
  2. Inter-service communication: In containerized environments, internal communication may still be possible through container networks without exposing ports externally.
