You have configured a virtualized Internet browser on your Windows XP professional computer. Using the virtualized Internet browser, you can protect your operating system from which of the following?

Mail bombing is an email-based attack that floods a mailbox and is not related to browser activity or browser virtualization.

A DDoS attack originates from external systems targeting a network or server; a virtualized browser provides no protection against inbound volumetric attacks.

A brute force attack targets authentication credentials over a network connection and is not mitigated by isolating the browser environment.

A virtualized Internet browser operates within a contained environment isolated from the host OS. When a malicious website attempts to install malware, the code executes within the virtual container and cannot access or persist to the real file system or registry of the Windows XP host. This isolation is the core security benefit of browser virtualization.
