  • Security for multi-tenant deduplication datastore against other tenants
    Patent number: 9811550
    Abstract: A method comprises receiving a first user hash value associated with data of a first user of a deduplication system, and comparing the first user hash value with each of a plurality of hash values stored in a first user hash store of the deduplication system. When it is determined that the first user hash value does not match one of the plurality of hash values stored in the first user hash store, first user hash value may be compared to each of a plurality of hash values stored in a global user hash store of the deduplication system associated with a plurality of users. When it is determined that the first user hash value matches one of the plurality of hash values stored in the global user hash store, the method may further comprise deleting the data after receiving the data associated with the first user hash value.

  • Hypercall-based security for hypervisors
    Patent number: 9697027
    Abstract: Hypercalls for a host machine and guest machines to a hypervisor are intercepted and routed to the hypervisor for execution on a hardware platform, responsive to the hypercall passing hypercall access rules. The intercepting may be performed by a hypercall access control layer that reloads a hypercall table that maps hypercalls from a host machine and guest machines to hypercall handlers, to identify a hypercall access control handler as the hypercall handler for the host machine and the guest machines. Upon passing the hypercall access rules, the hypercall is passed to the hypervisor.
