  • Publication number: 20200177637
    Abstract: The technology disclosed relates to enforcing multi-part policies on data-deficient transactions of independent data stores. In particular, it relates to combining active analysis of access requests for the independent object stores with inspection of objects in the independent object stores, each of the analysis and inspection generating and persisting object metadata in a supplemental data store, actively processing data-deficient transactions that apply to the objects by accessing the supplemental data store to retrieve object metadata not available in transaction streams of the data-deficient transactions, and actively enforcing the multi-part policies using the retrieved object metadata.

  • Patent number: 10659450
    Abstract: The technology disclosed relates to non-intrusively enforcing security during federated single sign-on (SSO) authentication without modifying a trust relationship between a service provider (SP) and an identity provider (IDP). In particular, it relates to configuring the IDP to use a proxy-URL for forwarding an assertion generated when a user logs into the SP, in place of an assertion consumer service (ACS)-URL of the SP. It also relates to configuring an assertion proxy, at the proxy-URL, to use the SP's ACS-URL for forwarding the assertion to the SP. It further relates to inserting the assertion proxy in between the user's client and an ACS of the SP by forwarding the assertion to the SP's ACS-URL to establish a federated SSO authenticated session through the inserted assertion proxy.

  • Publication number: 20190394244
    Abstract: A computer-implemented method for accessing a hosted service on client devices is described. The client devices include client software that uses a remotely delivered policy to redirect network requests for hosted services to a server to enforce visibility, policy and data security for network delivered services. The method can be used in conjunction with existing VPN and proxy solutions, but provides distinct additional functionality, particularly suited to corporate needs. Policies allow entities to centralize enforcement of service-specific restrictions across networks and communication channels, e.g. only certain users can download client records from a service—irrespective of the network used to access the service.

  • Publication number: 20190364095
    Abstract: The technology disclosed includes a system to apply data loss prevention (DLP) to cloud-based services for which no service-specific parser is available. The system determines that a known cloud-based service is being accessed via an application programming interface (API) and no service-specific parser is available for the API being accessed. The system applies a category-directed parser to the API being accessed. The category-directed parser includes multiple category-directed match rules derived from multiple syntaxes used by numerous known providers to implement a category of service. The category-directed parser collects metadata from content being conveyed via the API and assigns the collected metadata to variables. The system invokes a DLP processor and sends the collected metadata to the DLP processor for use in focusing analysis of content being conveyed via the API.

  • Publication number: 20190312860
    Abstract: A network security system and method implements dynamic access control for a protected resource using run-time contextual information. In some embodiments, the network security system and method implements a dynamic access ticket scheme for access control where the access ticket is based on run-time application context. In other embodiments, the network security system and method implements policy enforcement actions in response to detected violations using application programming interface (API) to effectively block detected policy violations without negatively impacting the operation of the application or the user of the application. In some embodiments, the network security system uses enterprise social collaboration tools to interact with the end-user or with the system administrator in the event of detected security incidents.
