摘要:
Intrusion detection method for detecting unauthorized use or abnormal activities of a targeted system of a network, comprising the steps: creating defined preconditions for each vulnerability related to the targeted system and/or for each attack that exploit one or several vulnerabilities; creating assurance references corresponding to said defined preconditions and considering the targeted perimeter capturing data related to the targeted system; comparing captured data with attack signatures for generating at least one security alert when captured data and at least one attack signature match; capturing assurance data from monitoring of the targeted perimeter comparing assurance data, issued from assurance monitoring of the targeted perimeter, with assurance references for generating assurance information when said data issued from assurance monitoring and at least one assurance reference match retrieving the preconditions of the generated security alert checking if assurance information corresponding to said preconditions has been retrieved generating a verified security alarm when generated security alert and its retrieved precondition match with at least one corresponding assurance information filtering said security alert when no match has been found between its retrieved preconditions and at least one corresponding assurance information; emitting a non verified security alert when no preconditions have been retrieved for this alert and/or no assurance reference corresponding to said preconditions has been defined.
摘要:
A technique is provided for detecting unauthorized use or abnormal activities of a targeted system of a network. The technique includes a comparison of captured data that relates to a targeted system with attack signatures to generate a security alert when the captured data and an attack signature match, a comparison of assurance metrics data from a monitored targeted perimeter with assurance references to generate assurance information when the assurance metrics data and an assurance reference match, a generation of a verified security alarm when the security alert and associated preconditions match a corresponding assurance information, a filtering of the security alert when no match has been found between the associated retrieved preconditions and the corresponding assurance information, and an emitting of a non verified security alert when no preconditions have been retrieved for the security alert and/or no assurance reference corresponding to the preconditions has been defined.

To control the publication of digital content on a web site managed by a publication server (SP) from a communication terminal (TC1), a control server (SC) capable of communicating with the publication server (SP) and the terminal provide the latter with an application (App) that is downloaded and implemented on the terminal. The application makes it possible to define the control parameters (ParC) associated with the digital content, said parameters comprising a period of validity for the content and a list of web sites authorised to publish the digital content, generate a key (Kc) associated with the digital content, encrypt the digital content with said key, and store the control parameters (ParC), the generated key (Kc), and the encrypted digital content in various databases. The application then generates a reference (Ref) associated with the digital content and requires the publication of the reference by the publication server in place of the digital content.

The present invention provides a method for detecting the hijacking of computer resources, located on an internal network implementing security and confidentiality criteria specific to this internal network, connected to an external network with no such security and confidentiality criteria, through a connection managed by a service provider, comprising: storing a connection parameter implemented by the computer resources to communicate with the external network; processing the stored parameter based on an irreversible function to generate a unique code that corresponds to said stored parameter but which does not allow the identification of said parameter from the corresponding generated code; and sending said generated code to a server located on the external network so that the server can analyze the activity of the computer resources from said unique code to detect any hijacking of the computer resources.

An exemplary technique is provided for detecting a hijacking of computer resources, located in an internal network implementing security criteria and confidentiality criteria specific to the internal network, connected to an external network with no security criteria and confidentiality criteria, through a connection managed by a service provider. The technique includes storing, at the internal network, a connection parameter implemented by the computer resources to communicate with the external network; processing, at the internal network, the stored connection parameter based on an irreversible function to generate a unique code that corresponds to the stored connection parameter but which does not allow the identification of the stored connection parameter from the corresponding generated unique code; and sending, at the internal network, the generated unique code to a server located on the external network so that the server can analyze an activity of the computer resources from the unique code and detect any hijacking of the computer resources.

Provided is a method and devices for overload control in a cloud computing environment. The method includes receiving a first message from a network element associated with the cloud computing environment. The first message includes information associated with a target virtual machine and a list of sessions from the one or more sessions to move from the serving virtual machine to the target virtual machine. Associating one or more client addresses with an address associated with the target virtual machine based on the list of sessions. And, treating the target virtual machine as the serving virtual machine if processing sessions associated with the list of sessions.
摘要:
A security management capability enables migration of individual security rules between storage/application locations. The migration of a security rule may include selection of a location at which the security rule is to be applied and migration of the security rule to the selected location at which the security rule is to be applied. The selection of the location at which the security rule is to be applied may be performed based on security rule policies and/or security rule location selection information. The security rule is migrated from a current location (e.g., a location at which the security rule is currently applied, a management system, or the like) to the selected location at which the security rule is to be applied. In this manner, a fluid security layer may be provided. The fluid security layer may be optimized for one or more of security level, performance, cost, or the like.

This invention pertains to a method for protecting a telecommunication network comprising at least one secure router (100) equipped with a topology map (103) of that network in order to determine the intermediate routers which constitute an optimal pathway for routing information, said secure router and said intermediate routers generating this topological map by sharing the lists of links (LSA1, LSA2, LSAn) using a communications protocol, characterized in that the secure router (100) performs the following steps: The step (109) of calculating and then saving, when a list of links (LSA1, LSA2, . . . LSAn) is received, at least one receiving fingerprint (hash(LSA1), hash(LSA2), . . . hash(LSAn)) of the lists received (LSA1, LSA2, . . . LSAn), The step (120) of calculating and then saving, when a list of links (LSA′1, LSA′2, . . . LSA′n) is transmitted, at least one sending fingerprint (hash(LSA′1), hash(LSA′2), . . . hash(LSA′n)) of the lists to be transmitted, and The step of comparing the receiving fingerprint (hash(LSA1), hash(LSA2), . . . hash(LSAn)) to the sending fingerprint (hash(LSA′1), hash(LSA′2), . . . hash(LSA′n) such that the sending of a list of links (LSA1, LSA2, LSAn) is inhibited if the receiving fingerprint is different from the sending fingerprint.
