Improved systems and methods for automated machine-learning, zero-day malware detection. Embodiments include a method for improved zero-day malware detection that receives a set of training files which are each known to be either malign or benign, partitions the set of training files into a plurality of categories, and trains category-specific classifiers that distinguish between malign and benign files in a category of files. The training may include selecting one of the plurality of categories of training files, identifying features present in the training files in the selected category of training files, evaluating the identified features to determine the identified features most effective at distinguishing between malign and benign files, and building a category-specific classifier based on the evaluated features. Embodiments also include by a system and computer-readable medium with instructions for executing the above method.

A hybrid cloud solution for securely extending a private cloud or network to a public cloud can be enhanced with tools for evaluating the resources offered by multiple public cloud providers. In an example embodiment, a public cloud evaluation system can be used to create a virtual machine (VM) in a public cloud to serve the function of a public cloud evaluation agent. The public cloud evaluation agent can instantiate one or more VMs and other resources in the public cloud, and configure the VMs and resources to execute performance evaluation software. The results of the performance evaluation software can be transmitted to a private enterprise network, and analyzed to determine whether the public cloud is an optimal public cloud for hosting an enterprise application.

A system for streaming packet captures over the Internet includes multiple network access devices, each operating as one of a gateway device, a wireless access point, and a network switch, and a management server communicatively coupled to the network access devices over the Internet for managing the network access devices. The management server maintains a persistent hypertext transport protocol (HTTP) connection with each of the network access devices over the Internet. The management server is to generate a bytecode based on a filtering expression for packet captures (PCAPs) representing one or more PCAPs filtering rules, transmit the bytecode to the network access devices without requiring the network access devices to compile the PCAPs filtering rules, receive PCAPs from the network access devices captured by the network access devices based on the PCAPs filtering rules, and merge the PCAPs received from the network access devices into merged PCAPs.

A cloud broker gateway interfaces with an enterprise network and one or more public cloud networks, including a first public cloud and a second public cloud. The cloud broker gateway receives a request for one or more computing resources from a tenant associated with the enterprise network, and directs the request to the first public cloud based on a brokerage policy for the tenant. The cloud broker gateway receives a response indicating the first public cloud cannot provide the one or more computing resources, and redirects the request to the second public cloud based on the brokerage policy for the tenant. The cloud broker gateway also establishes a hybrid cloud that provides access to the one or more computing resources between the second public cloud and the enterprise network.

Network policies can be used to optimize the flow of network traffic between virtual machines (VMs) in a hybrid cloud environment. In an example embodiment, one or more policies can drive a virtual switch controller, a hybrid cloud manager, a hypervisor manager, a virtual switch, or other orchestrator to create one or more direct tunnels that can be utilized by a respective pair of VMs to bypass the virtual switch and enable direct communication between the VMs. The virtual switch can send the VMs network and security policies to ensure that these policies are enforced. The VMs can exchange security credentials in order to establish the direct tunnel. The direct tunnel can be used by the VMs to bypass the virtual switch and allow the VMs to communicate with each other directly.

The technology disclosed relates to securely encrypting a document. In particular, it relates to accessing a key-manager with a triplet of organization identifier, application identifier and region identifier and in response receiving a triplet-key and a triplet-key identifier that uniquely identifies the triplet-key. Also, for a document that has a document identifier (ID), the technology disclosed relates to deriving a per-document key from a combination of the triplet-key, the document ID and a salt. Further, the per-document key is used to encrypt the document.

A computer-implemented method is described to monitor and control enterprise information stored on a cloud computing service (CCS). The method includes using a cross-application monitor to detect a cloud computing service (CCS) application programming interface (API) in use and a function or an activity being performed via the CCS API. The method also includes determining the function or the activity being performed via the CCS API by parsing a data stream based on the CCS API and identifying content being transmitted to the CCS. The method further includes applying a content inspection rule to find strings and interrelated strings in the content that are subject to content control and triggering a security action responsive to finding the strings and interrelated strings subject to content control in the parsed stream.

A system is configured to receive traffic being transported via a network; obtain, as a result of receiving the traffic, content from one or more packets associated with the traffic; analyze the content to identify one or more attributes associated with the content, where the one or more attributes correspond to at least one of: a network address, information associated with an application with which the traffic is associated, information associated with message content, or information associated with software content; determining that at least one attribute, of the one or more attributes, matches an attribute, of a set of attributes that are stored within a memory, where the set of attributes corresponds to a set of categories of traffic; identify a category, of the set of categories, that corresponds to the attribute; associate the category and the traffic; and process the traffic based on the associated category.
