ISC2 Certified Cloud Security Professional (CCSP) Practice Question

An organization hosts several Linux virtual machines in a public IaaS environment. A recent security assessment shows that the default security group exposes TCP port 22 to 0.0.0.0/0, and logs reveal thousands of external SSH brute-force attempts each day. The operations team needs to mitigate this vulnerability while still allowing administrators to manage the servers remotely. Which action is the most effective first step?

  • Upgrade the virtual machines to larger instance sizes to absorb the additional traffic.

  • Replace key-based SSH login with complex password authentication for all administrators.

  • Restrict the security group so that SSH is allowed only from the company's VPN or specific trusted IP ranges.

  • Enable full-disk encryption on each virtual machine volume.
