Abstract: A method for monitoring network activity includes initiating a training phase by a machine learning (ML) server. Data associated with normal network traffic through the ML server during the training phase is collected. A classification model is generated based on the collected data. The ML server switches the training phase to an active phase. An outbound request is received during the active phase. Whether the outbound request is an anomalous request is determined based on the classification model.

Abstract: Systems, methods, and software can be used to share content. In some aspect, an enterprise mobility management (EMM) server receives a command for provisioning a user for an enterprise service at an identity provider (IDP). The EMM server sends a user provisioning request to the IDP. The user provisioning request includes a user identity attribute and a user entitlement attribute, the user identity attribute identifies the user, and the user entitlement attribute indicates an access level associated with the user for the enterprise service. The EMM server receives a user provisioning response from the IDP. The user provisioning response indicates that the user is provisioned at the IDP for the enterprise service.
