Which of the following allows for agentless retrieval of the guest OS state, and is used for malware analysis, memory forensics, and process monitoring?

The correct choice focuses on Virtual Machine Introspection (VMI), which enables agentless retrieval of the guest operating system’s state. This technology operates by monitoring the virtual machine (VM) at a low level, accessing the hypervisor's data structures to gain insights into the OS without needing to install software agents within the virtual machines themselves.

VMI is particularly advantageous for scenarios such as malware analysis and memory forensics, where direct access to the OS state is crucial. By analyzing the memory and running processes from the hypervisor level, security analysts can detect and respond to malicious activities without alerting the malware to their presence. This capability makes VMI a preferred method in environments where minimizing the risk of detection is essential for effective incident response.

Furthermore, this method supports various security operations, including process monitoring, as it allows uninterrupted access to the internal workings of the virtualized environment. This positions VMI as a flexible tool for enhancing cloud security management by ensuring comprehensive visibility and control over VMs.

In contrast, other options like firewalls, Security Information and Event Management (SIEM) systems, and honeypots serve different purposes within the security landscape. Firewalls primarily focus on controlling inbound and outbound traffic based on predetermined security rules, while SIEM systems
