Abstract:

Methods, apparatuses, and computer-readable media protect sensitive data from being submitted in response to malicious e-mail. Responsive to initiating interaction with a remote site by clicking on a link, a method for protecting sensitive data from being submitted to a suspicious remote site responsive to a malicious e-mail comprises the steps of determining whether each remote target site a user attempts to access requests input of sensitive data; monitoring transmissions between a user's computer and remote target sites; and determining that a suspicious remote site is attempting to glean sensitive data from the user, responsive to a condition from a group of conditions consisting of: determining that a remote target site the user is attempting to access requests input of sensitive data; and detecting an attempt to transmit sensitive data between the user's computer and a remote target site.

Abstract:

Security from malicious attack is provided for a user environment running in a virtualized environment by a virtual security appliance (VSA) running outside of the user environment, but on the same computer system as the user environment. For example, a VSA running in a virtual machine can provide security for a user environment running in a second virtual machine. The separation of the VSA from the user environment enhances the robustness of the VSA against malicious attacks seeking to disable/bypass the protections of the VSA, while avoiding the costs and complexities of a physical security appliance.
