Abstract: A method to selectively encrypting packets includes filtering calls, at a virtual machine on a host, to connect sockets to server applications. When a call by a client application to connect a socket to a server application is detected, the method includes determining if the socket between the client and the server applications is to be encrypted based on identities of the client application, a user logged in on the virtual machine, or the client application and the user logged in on the virtual machine. The method includes filtering outbound packets in a protocol stack of the virtual machine. When the socket is to be encrypted and an outbound packet for the socket is detected, the method includes tagging the outbound packet for encryption by a hypervisor on the host and sending the outbound packet to a virtual network interface card (vNIC) emulated by the hypervisor.

Abstract: A method is provided for a kernel driver in an operating system to detect loading of images into memory and unloading of the images from memory. The method includes registering a callback routine for load-image notifications, receiving a load-image notification for an image and recording loading of the image, storing original code at or about an entry point of the image, and patching redirect stub code over the original code at or about the entry point. The method also includes receiving, from the redirect stub code, a redirected call to or about the entry point to execute a routine in the image. The redirected call identifies a driver object representing the image. The method further includes, based on the driver object, providing a mechanism to intercept unloading of the image and recording the unloading of the image.

Abstract: Exemplary methods, apparatuses, and systems perform a secure socket layer (SSL) protocol initialization and maintenance on behalf of a virtual machine (VM). When a secure virtual machine (SVM) receives a data packet sent by an application running on a VM, the SVM transmits a request message to the VM to enable the VM to perform a handshake with a destination computer to initiate an encrypted session between the VM and the computer. Once the encrypted session is active, the SVM encrypts the data packet, and transmits the encrypted data packet to the VM to perform the transmission of the encrypted data packet to the destination server.
