ISC2 Certified Cloud Security Professional (CCSP) Practice Question

A SaaS provider wants to reduce the risk that a compromise in one tenant's virtual machine will let an attacker move laterally to other tenants inside the same cloud data center. Budget allows changes in the virtualized network layer but no hardware refresh. Which control will most directly mitigate this risk?

  • Enable port security on each top-of-rack switch to restrict the number of MAC addresses per access port.

  • Configure DNSSEC for the provider's internal authoritative DNS zones to prevent spoofed responses.

  • Add erasure-coded storage across availability zones to increase data redundancy for every tenant.

  • Deploy microsegmentation policies enforced by a distributed firewall on the hypervisor's virtual switch.
