ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

A development team wants to ensure its Kubernetes-hosted Java microservice automatically blocks network traffic originating from any CIDR range that is not on an approved list, without adding new logic to each controller class. Which action best demonstrates a declarative security approach to meet this requirement?

  • Write a servlet filter that programmatically inspects the Origin header and rejects untrusted sources.

  • Wrap every endpoint in a try/catch block that throws an exception when the client IP is not trusted.

  • Create a NetworkPolicy YAML manifest that only allows pod ingress from the whitelisted CIDR blocks.

  • Invoke a GeoIP service from business logic to decide at runtime whether to accept the request.
