摘要:
A computer-implemented method may include receiving a request to access a network. The request may be sent from a virtual machine. The method may also include proxying the request to a network-access-control module, receiving a response from the network-access-control module, and transmitting the response to the virtual machine. Proxying the request to the network-access-control module may include assigning the virtual machine a virtual identifier. Proxying the request may also include creating a temporary interface. The temporary interface may be programmed to receive the response from the network-access-control module and transmit the response to the virtual machine. Various other methods, systems, and computer-readable media are also disclosed herein.

Multiple apps of an ecosystem on a computer securely exchange encrypted data according to an information control policy of an enterprise, without allowing unauthorized access from outside of the ecosystem. An ecosystem agent creates an ecosystem directory, which contains policy information and identification information concerning each specific app in the ecosystem, including the ecosystem agent. Each ecosystem app generates an asymmetric key pair, the public key of which it shares only with apps in the ecosystem through the directory. The ecosystem agent's private key is used to encrypt the directory. Data is securely communicated between apps in the ecosystem, by encrypting and decrypting messages and data objects with the appropriate ecosystem app keys. Each specific app in the ecosystem complies with enterprise information control policy. Ecosystem apps can read a policy from the directory, and receive policy updates from the enterprise.
摘要:
Selective projection of user interface elements between a host and a plurality of guests is provided according to a configurable policy. User interface elements generated by guests and/or the host are captured. It is determined whether to project captured elements into the user interface with which the user is currently interacting, based on the policy. In some cases, it is determined to project a captured element originating from a first user interface into a second user interface with which the user is currently interacting, based on factors such as source, destination, element attributes, element contents and/or element type. Responsive to such a determination, the captured element is projected into the current user interface, thereby presenting the projected element to the user.
摘要:
A computer-implemented method for processing web content may comprise receiving web content encoded with malicious steganographic code. Before presenting the web content, the method may comprise modifying the web content to create modified content such that information conveyed by the malicious steganographic code is at least partially corrupted in the modified content. Additionally, a functionality of the modified content may be at least substantially similar to a functionality of the web content following modification of the web content to create the modified content. Various other methods, computer-readable media, and systems are also disclosed.
摘要:
A computer-implemented method for detecting rootkits is disclosed. The computer-implemented method may include sending periodic security communications from a privileged-processor-mode region of a computing device. The computer-implemented method may also include identifying at least one of the periodic security communications. The computer-implemented method may further include determining, based on the periodic security communications, whether the privileged-processor-mode region of the computing device has been compromised. Various other methods, systems, and computer-readable media are also disclosed.
摘要:
A computer includes a portable environment including a portable file system located on a removable storage device, the portable environment using virtualization in a host operating system. A path translation module translates a virtualized path of a file in the portable file system to an actual path of the file. The virtualized path is the path in the context of a portable user application running in the portable environment, and the actual path is the path in the context of the host operating system. A malware detection module executing directly under the host operating system determines whether the file contains malware using the actual path of the file and takes remedial actions if malware is detected.
摘要:
Techniques for securing checked-out virtual machines in a virtual desktop infrastructure (VDI) are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for securing a checked-out guest virtual machine including receiving a request for checking-out a guest virtual machine hosted by a server network element, wherein checking-out the guest virtual machine comprises transferring hosting of the guest virtual machine from the server network element to a client network element. The method for securing a checked-out guest virtual machines may also include configuring a security module for the guest virtual machine in order to secure the guest virtual machine and providing the security module to the guest virtual machine when the guest virtual machine is checked-out.
摘要:
A computer-implemented method for determining whether to perform a computing operation that is optimized for a specific storage-device-technology type may comprise: 1) performing at least one proximate read operation by accessing a control location on a storage device and then accessing a test location on the storage device that is logically proximate to the control location, 2) performing at least one remote read operation by accessing a test location on the storage device that is logically remote from the control location, 3) determining, by comparing a length of time to access the proximate test location with a length of time to access the remote test location, a technology type of the storage device, and then 4) determining, based on the technology type of the storage device, whether to perform the computing operation. Corresponding systems and computer-readable media are also disclosed.
摘要:
A method includes creating a first virtual machine comprising a remote file system. The method further includes causing all input/output from a second virtual machine to be redirected to the remote file system, the first virtual machine and the second virtual machine being on a single physical computer. The file system is securely protected from any malicious code executing on the second virtual machine by the hardware enforced partitioning between the first virtual machine and the second virtual machine.
摘要:
Inbound and outbound traffic on a computer system are intercepted and compared to determine if the presence of malicious code is indicated. Outbound traffic that is sufficiently similar to recently received inbound traffic is indicative of the presence of malicious code. In some embodiments, if the presence of malicious code is indicated, the user, as well as other individuals or systems, are notified of the detection. In some embodiments, if desired, protective actions are initiated to hinder or block the propagation of the malicious code from the host computer system to other computer systems, as well as to remove or inactivate the malicious code on the host computer system.
