  • Hypervisor enforcement of cryptographic policy
    Patent number: 9892254
    Abstract: Techniques for restricting the execution of algorithms contained in applications executing on virtual machines executing within a computer system are described herein. A first sampled set of computer executable instructions is gathered from a virtual machine by a controlling domain and compared against a reference set of computer executable instructions. If the first set is similar to the reference set, and if the execution of the algorithm corresponding to the reference set is restricted by one or more computer system polices, one or more operations limiting the execution of the restricted algorithm are performed, thus ensuring conformance with the computer system policies.

  • Cross-region roles
    Patent number: 9894067
    Abstract: Techniques for using short-term credentials with access roles across regions are described herein. A request to assume a role associated with resources in a first region is received by a user in a second region. The request, which is digitally signed with credential associated with the user in the second region causes the generation of a short-term session credential that includes a session key and that can be used to assume the role. The user in the second region then assumes the role and, accordingly, can use the short-term session credentials to access the resources in the first region.

  • Buffer overflow exploit detection
    Patent number: 9892253
    Abstract: A call to a memory management application programming interface (API) that results in a buffer overflow due to inaccurate bounds checking could potentially leave the system vulnerable to being exploited by a third party. Approaches presented herein can monitor calls to these APIs in order to determine typical memory sizes passed to these APIs. During an initial baselining period a number of profiles are generated that indicate expected memory size parameters under various different call conditions, such from specific sources or call stacks. Comparing subsequently received API calls against the expected values from the relevant profile enables the legitimacy of an API call to be determined with relatively high accuracy. A suspicious call is identified based at least in part upon determining that the memory size of the call falls outside an expected range for that API and the relevant context.

  • Efficient data retrieval based on random reads
    Patent number: 9891866
    Abstract: Methods and systems are described herein to provide efficient data retrieval in a data storage system. Specifically, in cases where users of a data storage system are not overly sensitive to data retrieval time, such as the case for backup and archival data storage systems, random read requests may be fulfilled as part of sequential reads to reduce I/O operations. A data storage system may be divided into data storage zones. Sequential reads may be performed for data stored in those data storage zones with pending data retrieval requests. Data retrieval requests may be fulfilled based at least in part on the sequentially-read data.
