摘要： A device, system, and method are provided for detecting an email phishing attack by training graph neural network to detect phishing emails based on hypertext markup language (HTML) tags and cascading style sheets (CSS) included in an email. Noise is added during the training of the graph neural network to make the trained graph neural networks more robust against small changes in the training data.

摘要： An instantiated application includes both a runtime instantiation of an application image, and an administrative service operable to install in the instantiated application at least one security module during runtime of the instantiated application in a container. Prior to runtime, a design time agent can access the application image in a repository, examine the application image, and based on the examining, adding at least one security module to the application image prior to instantiation. During runtime, a runtime agent can query parameters of the container, such as static and dynamic variables available on the machine on which the container is running. The runtime agent processes these parameters in conjunction with predefined rules to determine an action such as starting, stopping, adding, and/or changing the security module, such as the method of packet inspection.

摘要： Computerized methods and systems inspect data packets received from a web server for the presence of a value from a list of prohibited values. If a prohibited value is absent, a gateway injects at least one JavaScript code segment for execution by a web browser. The at least one JavaScript code segment includes a plurality of JavaScript functions which include at least one security analysis JavaScript function and a plurality of modified JavaScript functions. Each of the modified JavaScript functions is created from a respective native JavaScript function to include at least one code segment that when executed inspects for at least one of: a dynamic modification of at least one JavaScript function from a prohibited list of JavaScript functions, a dynamic creation of at least one JavaScript function from the prohibited list of JavaScript functions, or a dynamic reference to a value from the list of prohibited values.

摘要： Processing client requests for duplicate-free server operations is particularly useful for creating and sending items using Microsoft Exchange Web Services (EWS). The system facilitates avoiding creation and sending of duplicate items. In contrast to conventional implementations that send a single command to create and then perform subsequent processing of an item, a feature of the present embodiment is using two commands: a first command to create the item, and a second command to subsequently process the item. In a specific implementation, an EWS item's provided ChangeKey property is used to keep track of the EWS's reply from the server to the client, thereby avoiding duplicate item creation.

摘要： Methods and systems for protecting components of a linked vehicle from cyber-attack are disclosed. These methods and systems comprise elements of hardware and software for receiving a packet; tunneling the packet to a terrestrial-based security service, analyzing whether the packet is harmful to a component in the vehicle, and at least one action to protect at least one component.

摘要： A network component has a set of one or more rules, each of which has a match component and an action component. If an incoming packet maps to the match component of a rule, then the packet is handled according to the rule's action component. If the rule also includes a limit component, then if the packet maps to the rule's match component, a family history of the rule is updated, and the packet is handled according to the rule's action component only if the rule's family history satisfies the rule's limit component.

摘要： A method and system is provided for a scalable clustered system. The method and system may handle asynchronous traffic as well as session backup. In the method and system, a home cluster member having ownership of a local session predicts designation of a an other cluster member to receive a packet associated with the local session and sends appropriate state information or forwarding instruction to the other network member.

摘要： Disclosed are methods and media for inspecting security certificates. Methods include the steps of: scanning, by a network security device, messages of a security protocol between a server and a client system; detecting the messages having a security certificate; detecting suspicious security certificates from the messages; and aborting particular sessions of the security protocol associated with the suspicious certificates. Preferably, the step of scanning is performed only on messages of server certificate records. Preferably, the method further includes the step of sending an invalid-certificate notice to the server and the client system. Preferably, the step of detecting the suspicious certificates includes detecting a use of an incorrectly-generated private key for the certificates. Preferably, the step of detecting the suspicious certificates includes detecting an unavailability of revocation information for the certificates. Preferably, the step of detecting the suspicious certificates includes detecting a use of an invalid cryptographic algorithm for the certificates.

摘要： A security gateway of a computer network receives incoming packets at one or more network interfaces. One or more security functions are applied to the packets. Reports of security function violations are recorded. The reports include the source addresses of the packets, the times that the packets were received, and descriptions of the violations. The descriptions include weights, and if the sum of the weights, for packets of a common source address that are received within a first time interval, exceeds a threshold, subsequent packets from that source address are dropped. Alternatively, in a “monitor only” mode, the common source address is logged but packets are not dropped. Optionally, encrypted packets and/or packets received at some network interfaces but not at other network interfaces are not dropped.
