  • Patent number: 11048551
    Abstract: A secured container provides access to enterprise data while isolated from the operating system of an Information Handling System (IHS). The secured container remains secured during its delivery and deployment. A secured container is configured to provide a user of the IHS with access to enterprise data. The secured container is encrypted using a symmetrical key that is transmitted to a secured storage that is isolated from the operating system of the IHS via out-of-band communications. The encrypted secured container is digitally signed using an asymmetric key pair. The digital signature and the encrypted secured container are transmitted to the IHS via in-band communications. At the IHS, the public key of the asymmetric key pair is used to validate the digital signature and the private symmetric key is retrieved from secured storage to decrypt the secured container. Additional embodiments provide a technique for securely migrating a secured container between IHSs.

  • Publication number: 20210168093
    Abstract: Systems and methods adjust workspaces based on available hardware resource of an IHS (Information Handling System) by which a user operates a workspace supported by a remote orchestration service. A security context and a productivity context of the IHS are determined based on reported context information. A workspace definition for providing access to a managed resource is selected based on the security context and the productivity context. A notification specifies a hardware resource of the IHS that is not used by the workspace definition, such as a microphone or camera that has not been enabled for use by workspaces. A productivity improvement that results from the updated productivity context that includes use of the first hardware resource is determined. Based on the productivity improvement, an updated workspace definition is selected that includes use of the first hardware resource in providing access to the managed resource via the IHS.

  • Publication number: 20210136082
    Abstract: Systems and methods provide multilevel authorization of workspaces using certificates, where all of the authorization levels may be authorized separately or may instead be authorized at once. A measurement of an IHS (Information Handling System) is calculated based on the identity of the IHS and based on firmware of the IHS. A measurement of the configuration of the IHS is calculated based on information for configuring the IHS for supporting workspaces and also based on the IHS measurement. A measurement of a workspace session is calculated based on properties of a session used to remotely support operation of the workspace by the IHS and also based on the configuration measurement. Workspace session data may by authorized at all three levels by evaluating the session measurement against a reference session measurement.

  • Publication number: 20210136115
    Abstract: Methods and system are provided for dynamically securing a workspace based on changes in the security context in which the workspace operates. Upon receiving a request from an IHS for access to a managed resource and receiving attributes of a risk context for the request, a risk score for the request is determined. A workspace definition that provides access to the managed resource is selected based on the risk score. A workspace definition includes security requirements for operation of the workspace by the IHS, where the security requirements are commensurate with the risk score. The workspace definition is transmitted to the IHS for operation of the workspace according to the security requirements. A risk context may include, IHS software, a physical environment in which the IHS is located, a physical location of the IHS, a classification of the requested resource, IHS hardware, and a user of the IHS.

  • Publication number: 20210133336
    Abstract: Systems and methods support secure transfer of data between workspaces operating on an IHS (Information Handling System). Upon a request for access to a first managed resource, such as protected data, a first workspace is deployed according to a first workspace definition. Upon a request for access to a second managed resource, a second workspace is deployed according to a second workspace definition. In response to an indication of a portion of the protected data from the first workspace being copied to a buffer supported by the IHS and of a request to paste the copied portion of the protected data to the second workspace, the protections provided by the second workspace are evaluated. If the protections of the second workspace are inadequate, an updated second workspace definition is selected that specifies additional protections. The second workspace is updated according to the updated second workspace definition and the transfer is permitted.

  • Patent number: 10990706
    Abstract: Systems and methods are provided for recording and validating modifications to a secured container. Modifications to the secured container by trusted parties are logged. The log may be maintained in a secured memory of an IHS (Information Handling System) and may be periodically validated. Each logged modification specifies a timestamp of the modification and the digital watermark assigned to the trusted party making the modification. Upon completing modifications, the secured container is sealed by imprinting the first digital watermark and the first timestamp at locations in the secured container specified by a watermarking algorithm assigned to the trusted party making the modification. Additional modifications may be serially watermarked on the secured container according the watermarking algorithm of the trusted party making each modification. The secured container is unsealed by re-applying each of the watermarking algorithms in reverse order.

  • Patent number: 10846408
    Abstract: A secured virtual environment provides access to enterprise data and may be configured remotely while isolated from the operating system of an Information Handling System (IHS). In secured booting of the IHS, references signatures are received via an out-of-band connection to the IHS. The reference signatures specify reference states for components of the IHS. Prior to launching a secured virtual environment, a trusted resource of the IHS, such as embedded controller isolated from the operating system, is queried for updated signatures specifying operating states of the component. The integrity of the IHS is validated based on comparisons of the respective reference signatures and updated signatures. If the integrity of the IHS is validated, a secured virtual environment is configured such that particular user may access the enterprise data according to applicable policies that may be periodically revalidated. The secured virtual environment may then be launched on the IHS.
