Which setting ensures that an attacker cannot read the information stored temporarily for use by another virtual machine (VM)?

Rationale

Dedicated memory ensures that an attacker cannot read the information stored temporarily for use by another virtual machine (VM).

Dedicated memory isolates the memory space of each virtual machine, preventing unauthorized access to sensitive information by ensuring that data is not shared or exposed to other VMs running on the same hardware. This isolation is crucial for maintaining the security and integrity of the virtual environment.

A (Encrypted file system) YOUR ANSWER

An encrypted file system secures data at rest by encoding files, making them unreadable without the proper decryption keys. However, it does not protect data in memory while it is actively being used by a VM, leaving it vulnerable to attacks from other VMs if memory is not dedicated.

B (Dedicated memory) CORRECT

Dedicated memory provides a secure environment where each VM has its own allocated memory space, effectively preventing any potential data leakage or unauthorized access from other VMs. This memory isolation is fundamental in multi-tenant environments to maintain confidentiality and security.

C (Dedicated processor) YOUR ANSWER

A dedicated processor assigns a specific CPU to a VM, which can enhance performance and reduce contention but does not inherently protect the memory space of the VM. An attacker could still access unprotected data in memory if the memory is not specifically isolated.

D (Encrypted network protocols) YOUR ANSWER

Encrypted network protocols, such as SSL/TLS, secure data in transit by encrypting the information exchanged over a network. While they protect data as it travels, they do not address the issue of protecting data stored in memory within a VM, which is crucial for preventing unauthorized access.

Conclusion

To ensure that an attacker cannot read the information stored temporarily for use by another virtual machine, dedicated memory is essential. This approach isolates memory usage, safeguarding sensitive data from being accessed by other VMs. Other options, such as encrypted file systems, dedicated processors, and encrypted network protocols, address different aspects of security but do not provide the necessary isolation of memory that dedicated memory offers.
