Abstract: A system and method for securing software as a service (SaaS) platforms by providing inter-service visibility. A method includes identifying, based on log data of a first service, a second service connected to the first service, wherein each of the first service and the second service is a set of functions for performing a respective task, wherein the second service is called by the first service; identifying a plurality of patterns in communications between the first service and the second service in the log data of the first service; creating, based on the identified plurality of patterns, a baseline for communications between the first service and the second service; detecting an anomalous communication between the first service and the second service, wherein the anomalous communication deviates from the baseline; and performing a mitigation action with respect to the detected anomalous communication.

Abstract: A computer device (referred to as a processing engine), system, and method are provided for refactoring an original security policy using an artificial intelligence (AI) engine including a large language model (LLM). The processing engine parses policy data converts the original security policy into a code representation and sends the converted code representation to the AI engine. The AI engine analyzes the original security policy by applying the LLM to the code representation and identifies policy insights that are sent to the processing engine.

Abstract: 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.

Abstract: A method and system is provided for setting network policies based on electronic devices connected to a network. The electronic devices present on the network are detected and their behavior is captured using profiles. These profiles are then used to generate network policies based on the electronic devices connected to the network. Instead of reacting to behavior of the electronic devices (e.g., anomaly detection to detect malware), the method and system sets the network policies to prevent unauthorized communications (e.g., before malware is present in the system).

Abstract: A system, method, and device are provided for detecting and mitigating a storage attack at the block level by generating canary blocks by marking blocks of data (referred to as memory blocks) such that other programs do not modify these canary blocks that are monitored to detect data storage attacks that attempt to modify the canary blocks and/or by monitoring statistical and behavioral features of activities over blocks, whether they can be modified by other programs or not. The system and method also backup the memory blocks by backing up memory blocks as they are modified. When a data storage attack is detected, the attack is stopped, and the files are remediated using the backup of the affected memory blocks.

Abstract: An automated method executed by circuitry is provided for monitoring a software platform including multiple pods that manage, deploy, and execute micro services. The method uses monitoring pods at locations of interest in the software platform to label transactions that pass through the monitoring pods. The labels applied to the transactions are sent to a security program for review.

Abstract: Methods and systems are provided for protecting DNS traffic locally on an electronic device (e.g., a smart phone) by capturing DNS traffic from network traffic transmitted from the device and ensuring the DNS traffic is routed to a trusted DNS server via a prescribed transmission protocol.

Abstract: 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.

Abstract: Disclosed are methods, media, and vault servers for providing a secure messaging system using vault servers in conjunction with client-side restricted-execution vault-mail environments. Methods include the steps of upon activating a vault-mail message containing sensitive content, removing the content from the vault-mail message; placing the content on a vault server; creating a link in the vault-mail message to the content on the vault server; sending the vault-mail message to a designated recipient; and upon activating the link, allowing the content to be only viewed in a restricted-execution session of a client application, wherein the restricted-execution session does not allow the content to be altered, copied, stored, printed, forwarded, or otherwise executed. Preferably, the activation of the vault-mail message is performed by a network-security gateway, and can be performed on a per-message basis.

Abstract: To validate data, a plurality of strings that match a predetermined regular expression is extracted from the data. A validated subset of the strings is identified. To determine whether the validated subset has been falsely validated, it is determined whether the validated subset satisfies each of one or more predetermined criteria relative to the plurality of strings. In one embodiment, the subset is determined to be falsely validated if at least one of the criteria is satisfied. In another embodiment, the subset is determined to be falsely validated if all of the criteria are satisfied. The data are released only if the subset is determined to be falsely validated.

Abstract: Methods, devices, and media for intelligent NIC bonding and load-balancing including the steps of: providing a packet at an incoming-packet port of a gateway; attaching an incoming-port identification, associated with the incoming-packet port, to the packet; routing the packet to a processing core; passing the packet through a gateway processing; sending the packet, by the core, to the operating system of a host system; and routing the packet to an outgoing-packet port of the gateway based on the incoming-port identification. Preferably, the gateway processing includes security processing of the packets. Preferably, the step of routing the packet to the outgoing-packet port is based solely on the incoming-port identification. Preferably, an outgoing-port identification, associated with the outgoing-packet port, has an identical bond-index to the incoming-port identification.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
