ISC2 Certified Cloud Security Professional (CCSP) Practice Question

Your organization has deployed a three-tier application (web, application, database) in separate subnets inside the same public-cloud virtual network. A new policy now requires that all traffic flowing between those subnets be encrypted while in transit, but the development team cannot modify or recompile the application code. Which infrastructure-level security control will best meet this requirement with the least impact on the workloads themselves?

  • Terminate TLS sessions on an internet-facing load balancer in front of the web tier.

  • Enable server-side encryption with customer-managed keys (CMKs) on the block storage volumes used by each tier.

  • Create IPsec VPN tunnel-mode connections between the subnets by configuring the cloud provider's virtual routers or gateways.

  • Apply restrictive stateful security group rules to permit only required TCP and UDP ports between the subnets.
