Abstract: Exemplary embodiments for data security include a data access proxy coupled with a database, further coupled with a server configured to operate the data access proxy to: identify a user and request to access a data item; validate the user and request, including inspecting the user's identity, evaluating the user's history, and evaluating permissions and restrictions associated with the user and the data item; access the database to retrieve the data item; inspect security attributes related to the data item; and transform the data item based on one or more privacy rules, including redacting the at least one data item, deleting information from the at least one data item, substituting information from the at least one private data item with other information, adding information to the at least one data item, providing synthetic data as a private data item, or providing proxy data for the data item.

Abstract: Systems and methods, in a lightweight connector including a processor communicatively coupled to a network interface, include connecting to a cloud-based system, via the network interface; connecting to one or more of a file share and an application, via the network interface; and providing access to a user device to the one or more of the file share and the application via a stitched connection between the network interface and the user device through the cloud-based system. The systems and methods can further include receiving a query for discovery; and responding to the query based on the one or more of the file share and the application connected thereto.

Abstract: Systems and methods include receiving a request, in a cloud system from a user device, to access an application, wherein the application is in one of a public cloud, a private cloud, and an enterprise network, and wherein the user device is remote over the Internet; determining if the user device is permitted to access the application; if the user device is not permitted to access the application, notifying the user device the application does not exist; and if the user device is permitted to access the application, stitching together connections between the cloud system, the application, and the user device to provide access to the application.

Abstract: Virtual private access systems and methods implemented in a clientless manner on a user device are disclosed. The systems and methods include receiving a request to access resources from a Web browser on the user device at an exporter in a cloud system. The resources are located in one of a public cloud and an enterprise network and the user device is remote therefrom on the Internet. The systems and methods also include performing a series of connections between the exporter and i) the Web browser and ii) centralized components to authenticate a user of the user device for the resources. The systems and methods further include, subsequent to authentication, exchanging data between the Web browser and the resources through the exporter. The exporter has a first secure tunnel to the Web browser and a second secure tunnel to the resources.

Abstract: A network device, such as a policy server, supports a plurality of different layer two (L2) networks. The network device receives a request to initiate a communication session from an endpoint device, selects an L2 network to which to assign the endpoint device, and assigns the endpoint device to the selected L2 network, selects one of a plurality of L3 network addresses for the policy server based on the selected L2 network, and sends the L3 network address to the endpoint device. The network device also includes a monitoring module that monitors activities of the endpoint device, and a plurality of L2 network interfaces, wherein each L2 network interface is associated with at least one L2 network. The L2 networks may be virtual local area networks.
