  • Managing virtual machine security resources
    Patent number: 11157300
    Abstract: In a virtualized environment where multiple guest virtual machines receive security services from multiple security virtual machines, a guest virtual machine automatically transitions to a new virtual security machine under various conditions. For example, the guest virtual machine may select a new security virtual machine when connectivity to the current security virtual machine degrades below a predetermined threshold, or in response to a request from the current security virtual machine indicating, e.g., that the current security virtual machine is about to shut down or otherwise terminate security services to the guest virtual machine.
    Type: Grant

  • Virtual machine security
    Patent number: 10776485
    Abstract: A virtual machine transmits local files to a secure virtual machine hosted by a hypervisor for malware detection. When malware is detected, the secure virtual machine can responsively provide remediation code to the virtual machine on a temporary basis so that the virtual machine can perform suitable remediation without a permanent increase in size of the virtual machine.
