20170041144 | CROSS-SITE REQUEST FORGERY DEFENSE - An HTML document includes a JavaScript element that manages CSRF token use.

The CSRF token is therefore stateless and isn't stored in a server-side repository. When the user later requests access to a server resource, the CSRF token is included in such request. This may be accomplished by adding a hidden input field that includes the CSRF token to the submission that's transmitted to the server. If the server cannot validate the received token using the HMAC key that was originally used to generate the token, the request is considered unauthorized and is not processed. | 2017-02-09 |

Suspending a component that is solely providing a presence notification frees up resources that may be utilized for another component performing computational work. | 2017-02-09 |

20170041188 | DIFFERENTIAL STAGING OF DEVICES IN BULK ENROLLMENT - Disclosed are various examples for differential staging of devices in bulk enrollment. In one example, a computing environment can detect a network connection event where a client device establishes a connection with a network device that is communicatively coupled to the computing environment. A configuration file can be copied from a data store of the at least one computing device to local memory of the client device. The configuration file can comprise one or more predefined configuration settings. A configuration of the at least one client device can be caused using the configuration file. The configuration can include automating user interface events on the client device to cause a setting of the client device to conform to the predefined configuration settings. | 2017-02-09 |
20170041189 | System and Method for Provisioning and Deployment of Application Environment on Hybrid Cloud Platform - This disclosure relates generally to computer resource management over multiple cloud platforms, and more particularly to a system and method for provisioning of application environment and deployment of application across hybrid cloud platform. In one embodiment, a method is provided for provisioning an application environment across a hybrid cloud platform. The method comprises generating a platform independent provisioning template based on at least one of a resource specification and a configuration data. The platform independent provisioning template is compatible with multiple cloud platforms. The method further comprises generating a plurality of target platform artefacts compatible with a corresponding plurality of target cloud platforms based on at least one of the resource specification and the configuration data, associating the plurality of target platform artefacts with the platform independent provisioning template, and provisioning the application environment across the hybrid cloud platform by executing the platform independent provisioning template on each of the plurality of target cloud platforms. | 2017-02-09 |
20170041190 | TRANSPORT NETWORK TUNNEL SETUP BASED UPON CONTROL PROTOCOL SNOOPING - Rather than there being a requirement that specific instructions be issued to cause a transport network tunnel to be configured, it is proposed herein to have a transport node autonomously determine that a transport network tunnel is to be configured and, responsively, cause the transport network tunnel to be configured. In general, a transport node (an L0/L1 device) adjacent to the packet device at the origin of LACP messages snoops on the LACP messages. The transport node may determine, based on the contents of a control LACP message, that a new packet network link is to be established between the origin packet device and a destination packet device. Responsive to the determining, the transport node adjacent to the origin packet device causes a transport network tunnel to be established between one of its ports and a port at a transport node adjacent the destination packet device. | 2017-02-09 |
20170041191 | PARALLEL COMPUTING SYSTEM AND MIGRATION METHOD - A first node stores therein accessed-area information that indicates a first area included in a storage area assigned to a target process, the first area having been accessed by the target process for a latest predetermined period of time. The first node stops the target process when an instruction to migrate the target process is received, transmits, to a second node, state information that indicates a state of the target process when the target process is stopped, and transmits first data stored in a first area to the second node, on the basis of the accessed-area information. The second node receives the state information and the first data from the first node, generates the target process on the basis of the state information, and restarts the target process using the first data. | 2017-02-09 |
20170041192 | CLOUD MODELS BASED ON LOGICAL NETWORK INTERFACE DATA - Examples relate to cloud models based on logical network interface data. Some examples disclosed herein may enable obtaining first cloud definition data that describes a first cloud infrastructure. The first cloud definition data may comprise logical network interface data that describes a first set of network interfaces to be bonded to form a first logical network interface for the first cloud infrastructure. Some examples further enable generating a first cloud model based on the first cloud definition data. The first cloud model may comprise first cloud configuration data that, when executed, causes the first cloud infrastructure to be deployed. Some examples further enable storing a first checkpoint image of the first cloud model. The first checkpoint image may comprise at least a portion of the first cloud configuration data. | 2017-02-09 |
20170041193 | APPLYING POLICIES TO SUBNETS - Associations are maintained among a plurality of subnets, policies, and client types. Each subnet has an associated client type and policy. For a particular client device, (i) a client type of the particular client device, and (ii) a client type associated with the subnet on which the particular client device is hosted is determined. For the particular client device, (i) the determined client type of the particular client device with (ii) the determined client type associated with the subnet on which the particular client device is hosted is compared. Responsive to a determination that the client type of the particular client device matches the client type associated with the subnet that hosts the particular client device, a policy is applied to the particular client device. | 2017-02-09 |
20170041194 | SYSTEMS AND METHODS OF DISCOVERING AND CONTROLLING DEVICES WITHOUT EXPLICIT ADDRESSING - A method of discovering a device in a communication network having multiple interconnected nodes includes continuously monitoring, by a device to be discovered, any IP packets sent by a discoverer. The method further includes transmitting, by the discoverer, an IP packet destined for a downstream device and receiving, by the device to be discovered, the IP packet. The method further includes determining, by the device to be discovered, whether the IP packet is intended for the device to be discovered. If the IP packet is not intended for the device to be discovered, retransmitting, by the device to be discovered, the IP packet to the downstream device via an egress port of the device to be discovered. | 2017-02-09 |
