WGU Updated Managing-Cloud-Security Exam Questions and Answers by adaline

A Hardware Security Module (HSM) is a dedicated, tamper-resistant device designed for creating, managing, and storing encryption keys. In cloud environments, HSMs are essential for securing cryptographic operations, such as SSL/TLS key management, digital signatures, and secure data transmission.

TPMs are hardware chips used to secure local devices, such as laptops. Memory controllers and RAID controllers manage system performance and storage but are not cryptographic devices.

HSMs provide strong protection against key theft or misuse by isolating cryptographic functions from general-purpose computing resources. They are often certified under standards like FIPS 140-2, ensuring compliance with stringent security requirements. In cloud services, customers can use provider-managed HSMs or deploy dedicated virtual HSM instances for secure key management.

The Stored Communications Act (SCA) is a United States jurisdictional data protection law enacted to limit and regulate forced disclosure of electronic communications by internet service providers. Managing Cloud principles describe the SCA as a legal framework that governs how stored electronic communications and customer data may be accessed by government entities.

The act establishes requirements for warrants, subpoenas, and court orders before service providers can disclose stored data. This protection is particularly relevant in cloud environments, where service providers store large volumes of customer data on behalf of organizations.

The other options are incorrect. APP8 and APP11.1 are Australian Privacy Principles, and GDPR applies to the European Union. Therefore, the Stored Communications Act is the correct U.S. jurisdictional protection.

The Destroy phase of the cloud data life cycle is where information is permanently removed from systems. A common technique in cloud environments for this phase is crypto-shredding (or cryptographic erasure). Rather than physically destroying the media, crypto-shredding involves deleting or revoking encryption keys used to protect the data. Once those keys are destroyed, the encrypted data becomes mathematically unrecoverable, even if the underlying storage media remains intact.

This method is particularly useful in cloud environments where storage is virtualized and hardware cannot easily be physically destroyed. Crypto-shredding provides compliance-friendly assurance that sensitive data such as personally identifiable information (PII), financial data, or healthcare records cannot be accessed after retention periods expire or contractual obligations end.

By incorporating crypto-shredding into the Destroy phase, organizations align with standards for secure data sanitization. This ensures legal defensibility during audits and e-discovery and demonstrates proper lifecycle governance. The emphasis is on making data inaccessible while still maintaining operational efficiency and environmental responsibility.

While cloud providers typically offer built-in encryption, customers should apply additional encryption for sensitive data to maintain defense-in-depth. Encrypting files and folders before uploading them ensures that even if provider-side protections fail, data remains confidential.

WAFs protect applications from web threats, DAM tools monitor database use, and block storage versus file storage is an architecture choice. None of these directly provide an extra protective layer for stored data.

By maintaining control of their encryption keys, customers ensure compliance with data protection standards such as GDPR, HIPAA, or PCI DSS. This practice also mitigates insider threats within the provider’s environment and supports secure multi-cloud strategies. Encryption remains the strongest safeguard for protecting sensitive files in public cloud storage.
