Certified Cloud Security Professional (CCSP)Cloud Concepts, Architecture and DesignHard

An organization is migrating its on-premises virtualized environment to an Infrastructure as a Service (IaaS) cloud provider. The security team is concerned about the potential for 'hypervisor escape' attacks, where an attacker gains unauthorized access from a guest virtual machine to the underlying hypervisor or other guest virtual machines. Which fundamental cloud security challenge does this concern directly relate to?

  1. AShared Technology Vulnerabilities
  2. BInsufficient Due Diligence
  3. CData Portability
  4. DAPI Security
Show answer & explanation

Correct answer: A. Shared Technology Vulnerabilities

Hypervisor escape is a direct example of a 'shared technology vulnerability' in IaaS, where a flaw in the shared hypervisor or virtualization technology can be exploited to compromise the isolation between tenants, affecting multiple customers.

Why the other options are wrong

  • B. Insufficient due diligence is a process failure, not a specific technical challenge like hypervisor escape.
  • C. Data portability relates to moving data between clouds, not hypervisor exploits.
  • D. API security focuses on securing programmatic interfaces, not the virtualization layer itself.

Shared Technology Vulnerabilities

Security challenges arising from shared underlying cloud infrastructure components (e.g., hypervisors, network devices), where a vulnerability can affect multiple tenants.

  • Includes hypervisor escape, shared memory attacks
  • Requires strong patching and configuration management by CSP
  • A key concern in multi-tenant environments

Memory trick: Shared tech, shared risk.
