ISC2 Certified Cloud Security Professional (CCSP) Practice Question

Your organization has deployed a three-tier web application in a public cloud. Web servers sit in a public subnet behind a load balancer, while application and database servers reside in a private subnet that currently has no inbound rules. Administrators must occasionally use SSH from the corporate network to manage the private servers, but security policy forbids exposing SSH from the Internet. Which network security control best satisfies the requirement while minimizing the private subnet's attack surface?

  • Install host-based intrusion detection systems on all private instances to block unauthorized SSH attempts

  • Add an inbound security group rule permitting SSH from any source to the private subnet during approved maintenance windows

  • Place a honeypot in the private subnet to attract and contain external attackers

  • Deploy a hardened bastion (jump) host in a small public or dedicated management subnet and require administrators to SSH to private servers through it
