A method for detecting a particular data traffic in a communication network having a plurality of nodes comprises: maintaining a list of detecting scans to be applied to an incoming data traffic; receiving the incoming data traffic; and applying a subset of the detecting scans in the list to the incoming data traffic. A network node for detecting a particular traffic in a communication network having a plurality of nodes comprises: a list of detecting scans to be applied to an incoming data traffic; an input for receiving the incoming data traffic; and an inspection chain, which applies a subset of detecting scans in the list to the incoming data traffic.
摘要:
A system and method for managing trusted platform module (TPM) keys utilized in a cluster of computing nodes. A cluster-level management unit communicates with a local TPM agent in each node in the cluster. The cluster-level management unit has access to a database of protection groups, wherein each protection group comprises one active node which creates a TPM key and at least one standby node which stores a backup copy of the TPM key for the active node. The local TPM agent in the active node automatically initiates a migration process for automatically migrating the backup copy of the TPM key to the at least one standby node. The system maintains coherency of the TPM keys by also deleting the backup copy of the TPM key in the standby node when the key is deleted by the active node.
摘要:
A method for preserving privacy during authorisation in pervasive environments is described. The method includes an authorisation phase in which the user is provided with a reusable credential associated with verifiable constraints, and an operation phase where the service provider verifies the reusable credential before authorising the user. Third parties cannot link plural uses of the credential to each other, and the service provider cannot link plural uses of said credential to each other.
摘要:
A method of controlling access to content comprises receiving, at a domain gateway (3) of a domain (4), a request from a device (5) in the domain for access to the content. It is determined at the domain gateway whether the number of devices in the domain currently accessing the content is equal to a specified maximum number of devices that may simultaneously access the content. The maximum number of devices that may simultaneously access the content is independent of the number of devices in the domain. If the determination is that the number of devices in the domain currently accessing the content is less than the specified maximum number the request is allowed, otherwise it is refused.

摘要:
A mobile node, a gateway node and methods are provided for securely storing a content into a remote node. The mobile node, or a gateway node of a network providing access to the mobile node, applies a content key to the content prior to sending the content for storage in the remote node. The content key is generated at the mobile node, based on a random value obtained from an authentication server, or directly at the authentication server if applied by the gateway node. The content key is not preserved in the mobile node or in the gateway node, for security purposes. When the mobile node or the gateway node fetches again the content from the remote node, the same content key is generated again for decrypting the content. The remote node does not have access to the content key and can therefore no read or modify the content.

A method and communication node for providing secure communications and services in a High Availability (HA) cluster. The communication node comprises an Operating System (OS) that detects an unavailability of a first service application process and switches a second service application process from the first state to the second state, the second service application being selected for taking over service currently provided from the first service application process, the first state and the second state each being associated to a set of rights in the cluster. The OS generates a private key for the second service application process based on its second state. The set of rights associated to the second state allows the OS to replace the first service application process with the second service application process for providing secure communications between the second service application and other service application processes in the HA cluster.

A system and method for managing a hybrid firewall solution, employing both hardware and software firewall components, for a cloud computing data center is provided. A virtual application is hosted by a first plurality of application virtual machines and a second plurality of firewall virtual machines provides firewalling services for traffic associated with the virtual application. A cloud management entity determines that the virtual application requires an increased number of application virtual machines. A security profile for the virtual application is verified to determine if an increased number of firewall virtual machines is required by the increased number of application virtual machines. The cloud management entity can instantiate additional application virtual machines and firewall virtual machines as required.
