  • Patent number: 11822676
    Abstract: Example methods are provided to for automated determination of a minimal set of privileges that are required to execute a workflow in a virtualized computing environment. While the workflow is being executed, interactions with a user interface are recorded. The interactions include application program interface (API) calls. The method identifies the privileges that are used to execute the API calls, and the identified privileges are combined to form the minimal set of privileges. A model is generated that associates the minimal set of privileges to the workflow, and the model is applied to determine the privileges to assign to users that will be performing the same workflow.

  • Patent number: 11805114
    Abstract: A system, method, and computer-readable storage medium provide single sign-on (SSO) in a nested virtualization environment by routing authentication tokens received from an authentication server through the hierarchy of virtual machines (VMs) using secure data communications tunnels between each hypervisor and its respective VMs. A key store stores SSO authentication tokens for users of the nested VMs, and a key controller ensures that each login by a user to a separate VM is associated with its own token. Each login request is uniquely tagged to identify the particular VM requesting credentials, so that the responsive authentication token can be properly routed through the hierarchy. Moreover, session preferences may be associated with each user and/or each VM, enabling a rules evaluator to determine, for each login request, whether SSO functionality should be provided or whether the user should be required instead to provide new login credentials.

  • Patent number: 11797665
    Abstract: A processing system includes a branch prediction structure storing information used to predict the outcome of a branch instruction. The processing system also includes a register storing a first identifier of a first process in response to the processing system changing from a first mode that allows the first process to modify the branch prediction structure to a second mode in which the branch prediction structure is not modifiable. The processing system further includes a processor core that selectively flushes the branch prediction structure based on a comparison of a second identifier of a second process and the first identifier stored in the register. The comparison is performed in response to the second process causing a change from the second mode to the first mode.

  • Patent number: 11782744
    Abstract: A data processing system has a processor, a system memory, and a hypervisor. The system memory stores program code and data in a plurality of memory pages. The hypervisor controls SLAT (second level address translation) read, write, and execute access rights of the plurality of memory pages. A portion of the plurality of memory pages are classified as being in a secure enclave portion of the system memory and a portion is classified as being in an unsecure memory area. The portion of the memory pages classified in the secure enclave is encrypted and a hash is generated for each of the memory pages. During an access of a memory page, the hypervisor determines if the accessed memory page is in the secure enclave or in the unsecure memory area based on the hash. In another embodiment, a method for accessing a memory page in the secure enclave is provided.

  • Patent number: 11755730
    Abstract: Examples of the present disclosure describe systems and methods for a behavioral threat detection engine. In examples, the behavioral threat detection engine manages execution of one or more virtual machines, wherein each virtual machine processes a rule in relation to a context. The behavioral threat detection engine uses any of a variety of techniques to identify when events occur. Accordingly, the behavioral threat detection engine provides event indications, in the form of event packets, to one or more virtual machines, such that corresponding rules are able to process the events accordingly. Eventually, a rule may make a determination as to the presence or absence of a behavior. As a result, execution of the associated virtual machine may be halted, thereby indicating to the behavioral threat detection engine that a determination has been made. Thus a behavioral threat detection engine employs a behavior-based approach to detecting malicious or potentially malicious behaviors.

  • Patent number: 11720707
    Abstract: A conference management system (“system”) facilitates data compliance in recording conversations between users. A host user can send an electronic invitation for a meeting to participants. Upon accessing the invitation, the participants can be presented with two options to join the conference—a first option using which a participant can join the meeting by providing consent to recording the meeting and a second option using which the participant can join the meeting by opting-out of recording of the meeting. When a participant opts-out of the recording of the meeting, the conference management system ensures that the recording is performed in compliance with a data compliance policy applicable to the participant who opted out of recording.

  • Patent number: 11611879
    Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for improvements to security checks in a fifth generation (5G) New Radio (NR) network, including mechanisms to avoid redundant access stratum (AS) security checks. The wireless device may determine that an on-demand system information block (SIB) request is pending transmission and may buffer the on-demand SIB in response to determining that a connection establishment procedure will be initiated within a specified time period. The wireless device may then perform a unified security procedure for the on-demand SIB request and the connection establishment procedure, including confirming connection security. Further, in response to confirming connection security, the wireless device may use an on-demand SIB received from the network without confirming a corresponding on-demand SIB signature.
