    摘要： Disclosed herein is a system and method for identifying a spam email message. To identify a spam message a similarity measurement hash and a sender hash is generated for each email message. Two or more previously received email messages are compared with an incoming email message. The incoming email message is identified as a spam message when the similarity measurement hash between incoming message and one of the received messages matches and the corresponding sender hash does not match. The system may integrate with other email servers through a DNS to identify spam emails across different organizations and locations. The system and method may further apply rules to particular match to whitelist a potential spam email.

    摘要： An aspect of recovery from rolling security token loss includes storing, in a memory device accessible by a server computer, a token pair (B) transmitted to a client device. The token pair (B) includes an access token (a2) and a refresh token (r2) and is generated as part of a refresh operation. An aspect also includes storing, in the memory device, a refresh token (r1) that was generated by the server computer before generation of the token pair B. The refresh token (r1) and the refresh token (r2) are each tagged as a valid refresh token. An aspect further includes receiving, at the server computer, a request to access a network resource that includes the access token (a2), invalidating the refresh token (r1), and providing the client device with access to the network resource.

    摘要： A mechanism is provided for sending a password to a terminal. A password send request is received. The status of each of a plurality of terminals coupled to the information processing device via a network is acquired. On the basis of the acquired statuses, at least one item is selected from a group comprising the terminal serving as a destination for the password, the communication method with the terminal, or the method for inputting the password in the terminal. The password is then sent to the selected terminal via a network.

    摘要： A binary library overload instruction is received at an embedded computing device that executes a write-protected firmware build. The binary library overload instruction specifies a write-protected binary library of the write-protected firmware build to be overloaded by execution of an alternative binary library instead of the write-protected binary library of the write-protected firmware build. The alternative binary library is configured within a random access memory (RAM) storage area to execute instead of the write-protected binary library as specified in the received binary library overload instruction. The write-protected firmware build is executed using the alternative binary library instead of the write-protected binary library specified in the binary library overload instruction.

    摘要： Embodiments can provide a method for accessing an endpoint, including: receiving, from a privileged user, a request for accessing the endpoint; providing, by a user behavior analytics device, a risk score with respect to the privileged user, wherein the risk score is calculated based on at least one action performed by the privileged user. If the risk score is lower than a first predefined value, providing access to the endpoint for the privileged user. If the risk score is higher than a second predefined value, denying the request for accessing the endpoint. If the risk score is between the first predefined value and the second predefined value, performing at least one of: providing, by a privileged identity management server, a multi-factor authentication against the privileged user; and rerouting the request for accessing the endpoint for approval.

    摘要： Assessment of threat risks associated with a given mobile device application (app) on a device type specific basis, so that the threat assessment is specific to a particular device type that is suitable for running the given app. The assessed device-type-specific risk is represented as device-type-specific risk metadata, which is associated as metadata with the given app. For example, the metadata may be stored along with the given app in a common repository that includes many apps. In some embodiments, the device-type-specific risk metadata is generated and stored comprehensively for all apps and device types used in an enterprise. The device-type-specific risk assessment, and corresponding device-type-specific risk metadata, may be based upon run time behavior of the given app on a given device type.
