Abstract: Disclosed herein are systems and method for providing agentless security of virtual machines. In one aspect, the method intercepts, by a virtual switch filtering extension of an extensible virtual switch on a host processor, a data packet in an outbound transmission from a virtual machine to a destination device. The method blocks, by the virtual switch filtering extension, transmission of the data packet from the virtual machine to the destination device based on determining non-compliance with a set of predefined rules of the first virtual machine. The method generates a first event indicative of the blocking and creates a filtering log comprising a list of events, filtered by the virtual switch filtering extension, including the first event. The filtering log is either transmitted or cached based on whether accessibility is available to a management service database.

Abstract: Disclosed herein are systems and method for providing agentless security of virtual machines. In one aspect, the method intercepts, by a virtual switch filtering extension of an extensible virtual switch on a host processor, a data packet in an outbound transmission from a virtual machine to a destination device, wherein the virtual switch filtering extension is also configured to intercept data packets in inbound transmissions to the virtual machine. In response to determining that the data packet is not in compliance with the set of predefined rules associated with the virtual machine, the method prevents, by the virtual switch filtering extension, transmission of the data packet from the virtual machine to the destination device.

Abstract: An agentless intrusion detection and prevention digital processing system and environment, or virtual firewall is disclosed. The agentless, virtual firewall monitors and controls digital data communications between a digital communications network and one or more virtual digital processing machines. The virtual digital processing machines, or virtual machines (VMs), are operative on a host digital processor under the supervision of a hypervisor software module. The agentless, virtual firewall is implemented as part of a virtual switch filtering extension to an extensible virtual switch running in a kernel mode as part of the hypervisor software module.

Abstract: A self-adapting iterative solver is provided that employs a self-adapting process for extracting singularities for solving linear systems of equations. The self-adapting iterative solver dynamically determines how to adapt its performance in the presence of one or more singularities encountered in a linear system of equations. In certain embodiments, the self-adapting iterative solver can identify possible singularities, and then analyzes its performance for adapting to a treatment of the possible singularities that provides a desired performance (i.e., for achieving convergence to a solution). Thus, rather than being pre-configured for providing a certain treatment of (e.g., eliminating) certain pre-identified singularities, in certain embodiments, the iterative solver adapts its treatment of singularities based on its computing performance.
