  • Patent number: 11431591
    Abstract: Described embodiments provide systems and methods for indicating virtual workspace performance on a graphical user interface of a computer system. In one such method, the computer system identifies one or more components of a virtual workspace executed on behalf of a user of the computer system, and analyzes a plurality of performance measurements of the identified one or more components of the virtual workspace. For each of the identified one or more components, the computer system determines an aggregated performance measurement for the component based on the plurality of performance measurements of the component, compares the aggregated performance measurement to a threshold, and selects a graphical indicator from a plurality of predetermined graphical indicators responsive to the comparison. The computer system renders, within a graphical user interface of the computer system, an identifier of the component and the selected graphical indicator.

  • Patent number: 11429753
    Abstract: Techniques for encrypting keyboard data prior to its being received by an operating system of an endpoint device, reducing the possibility of unencrypted keyboard data being logged by a keylogger application running on the endpoint device. The techniques employ an encryption filter communicably coupled between a keyboard and the endpoint device. The encryption filter receives unencrypted keyboard data from the keyboard, encrypts the keyboard data, and provides the encrypted keyboard data to the operating system of the endpoint device. The techniques can be employed in association with a back-end data processing center of a security standard compliant organization, which can receive the encrypted keyboard data from the endpoint device, and decrypt the keyboard data for use on a host system. In this way, access and/or storage of unencrypted keyboard data at the endpoint device can be avoided.

  • Patent number: 11429633
    Abstract: A primary domain controller maintains synchronization of directory information (e.g., Active Directory information) between local directory controllers in a local domain and cloud directory controllers in a cloud domain. The primary domain controller subscribes to directory event reports for selected directory events occurring at the local directory controllers, such as addition, deletion or modification of user accounts. Upon receiving the directory event reports, the primary domain controller creates corresponding directory event records in an event log, and regularly forwards contents of the directory event records of the event log to the cloud directory controllers for use in updating system directory information in the cloud domain.

  • Patent number: 11431482
    Abstract: A system and method for securely encrypting and booting a headless appliance. A computerized method is disclosed that includes: providing the network appliance with content encrypted with a secret key; launching the network appliance in a fallback configuration that provides limited operational capabilities; forwarding a request for the secret key to an online service that independently utilizes an identity provider to establish trust with an appliance administrator; receiving the secret key from the online service upon establishment of trust with the appliance administrator; decrypting the content with the secret key received from the online service; and utilizing the content to launch the network appliance in a full configuration.

  • Patent number: 11429566
    Abstract: Systems and methods for classification of log data at the source into sets of critical and non-critical data. Critical data may be indexed and processed normally, while non-critical data may be provided to and stored by the cloud-based log aggregation system without indexing, at significantly lower cost in terms of processing and storage. In the event that non-critical data is required for troubleshooting or analysis, the non-critical data may be indexed dynamically on request. Because the non-critical data is stored at the cloud-based log aggregation system, it may be quickly indexed and added to the critical data, without additional consumption of bandwidth or delays due to transmission. Dynamic selection and classification of critical and non-critical data may thus allow an enterprise to balance costs and availability of indexed data.

  • Patent number: 11425052
    Abstract: Methods, systems, and apparatuses for discovering dynamic path maximum transmission unit (PMTU) between a sending computing device and a receiving computing device (e.g., a client device and a host device) are described herein. A sending computing device may iteratively transmit bursts of probe packets, each burst being defined by a search range between a maximum packet size and a minimum packet size. The sending computing device may iteratively update the search range based on the previous iteration until the search converges on the PMTU. When the PMTU is discovered, each of the computing devices may update their transport and presentation layer buffers based on the discovered PMTU without any other protocol level disruption. In a multi-path scenario, the computing device may discover PMTU for each of the paths and select a performance optimal path based on the individual PMTUs and other network characteristics such as loss, latency, and throughput.

  • Publication number: 20220255839
    Abstract: Described embodiments provide systems and method for intelligent path selection to reduce latency and maintain security. A client can request access to a server and multiple connections can be initiated to the requested destination, for example, a direct connection from a branch office and a backhauled connection through a data center. Traffic via the second connection can be controllable by application of at least one rule of the data center. A device can determine a delay in the exchange of data via the connections and a security level of the connections. The determination of the delay in the exchange of data via the another connection can be based on in part feedback about the application of the rule. The device can connect a client device to a server through one of the connections using the determination of the delay and the security level of the connection.

  • Patent number: 11411974
    Abstract: The implementations described herein provide a tool for identifying security issues and applying security policies to the service(s) and/or microservices. Rather than a user (such as an administrator) reactively diagnosing security incidents, the systems and methods described herein may provide a tool by which the user can proactively monitor the use of the services and microservices for security issues and control the user of such microservices and services via policies. The systems and methods allow API granular policy control to determine which APIs may be granted or denies access based on a variety of criteria, such as but not limited to the source of the request, the specific API being called, temporal conditions, geography and so forth. The user can identify security concerns or issues on a per API basis.

  • Patent number: 11409716
    Abstract: Methods and systems for shared file conflict detection on a computing device are described herein. A computing device may store a shared file that may be accessed by a variety of other computing devices. An operating system executing on one or more computing devices may generate file handles corresponding to file operations associated with the shared file. One or more of the computing devices may receive, from a remote computing device, a request for a file operation associated with the shared file. A notification corresponding to file handles associated with the shared file may be transmitted to a user. The request for the file operation may be implemented or rejected based on file handles associated with the shared file, the file operation, and/or whether the file operation may cause an application to crash or cause data corruption.
