A man-in-the-middle protection module can monitor data traffic exchanged between a source and destination nodes over a source-destination link via a network. The module can utilize a traffic probe packet to determine a packet delay associated with the data traffic. The module can store the packet delay and can determine that the packet delay is greater than a normal packet delay. If so, the module can determine that an attacker has compromised the source-destination link. The module can command a virtual machine associated with the source node to be decommissioned. The module can instruct a virtualization orchestrator to create a new source node. The data traffic can be rerouted to be exchanged between the new source node and the destination node over a new source-destination link via the network. The module can create and send fake data traffic towards the MitM attacker over the source-destination link via the network.

Certain edge networking devices such as application gateways may report status to a cloud-based threat management platform using a persistent network connection between the gateway and the cloud platform. Where a cloud computing platform for an edge networking device or the treat management platform imposes periodic timeouts, the threat management platform may monitor connects and disconnects for edge devices and asynchronously evaluate connection status of edge devices independently of a heartbeat or other signal through the persistent connection in order to distinguish periodic timeouts imposed by the cloud computing platform from networking devices that are compromised or malfunctioning.

An anomaly detection method includes receiving, at a processor, a request including a query that references a database. A plurality of attributes is identified based on the request. The processor concurrently processes the query to identify a result, and analyzes the plurality of attributes to identify an anomaly score. When the anomaly score exceeds a first predefined threshold, a signal representing a quarantine request is sent, and a signal representing the result is not sent. When the anomaly score is between the first predefined threshold and a second predefined threshold, a signal representing a notification and a signal representing the result are sent. When the anomaly score is below the second predefined threshold, a signal representing a quarantine request is sent, and a signal representing the result is not sent.

Systems and methods implemented in a node in a cloud-based system include loading a data structure into memory, wherein the data structure includes cities mapped to cells where the cells cover all of the Earth; receiving a call with a given latitude and longitude of a user device; finding a closest city to the given latitude and longitude utilizing the data structure; and providing the closest city in response to the call. The systems and methods can also include utilizing the closest city for policy in the cloud-based system for the user device.

A method for providing a notification system in a virtual private network (VPN), the method comprising transmitting, to a user device, a notification indicating that data of interest requested by the user device potentially includes harmful content, the data of interest to be obtained from a host device; receiving, from the user device, a response indicating that the data of interest is to be received by the user device; receiving, based at least in part on the response, the data of interest from the host device; and transmitting the data of interest to the user device. Various other aspects are contemplated.

According to certain embodiments, a provisioning manager comprises an interface and processing circuitry. The interface is configured to obtain provisioning data from a provisioning database. The processing circuitry is configured to prepare one or more configuration files based on the provisioning data. The configuration file(s) indicate how to provision one or more service instances. The processing circuitry is further configured to commit the configuration file(s) to one or more repositories in order to make the configuration file(s) available to at least one of the service instances. The processing circuitry is further configured to send one or more notifications indicating to one or more of the service instances that the configuration file(s) have been committed to the one or more repositories.

Techniques and mechanisms for using passively collected network data to automatically generate a fingerprint prevalence database without the need for endpoint ground truth. The process first clusters all observations with the same fingerprint string and similar source and destination context. The process then annotates each cluster with descriptive information and uses a rule-based system to derive an informative name from that descriptive information, e.g., “winnt amp client” or “cross-platform browser”. Optionally, the learned database may be augmented by a user to clarify custom process labels. Additionally, the generated database may be used to report the inferred processes in the same way as databases generated with endpoint ground truth.

Packets may be received by a packet security gateway. Responsive to a determination that an overload condition has occurred in one or more networks associated with the packet security gateway, a first group of packet filtering rules may be applied to at least some of the packets. Applying the first group of packet filtering rules may include allowing at least a first portion of the packets to continue toward their respective destinations. Responsive to a determination that the overload condition has been mitigated, a second group of packet filtering rules may be applied to at least some of the packets. Applying the second group of packet filtering rules may include allowing at least a second portion of the packets to continue toward their respective destinations.

Disclosed herein are techniques for detecting phishing websites. In one embodiment, a method is disclosed comprising receiving, at a server, a request for a webpage from a client device; generating, by the server, and inserting an encoded tracking value (ETV) into the webpage; inserting, by the server, dynamic tracking code (DTC) into the webpage, the inserting of the DTC further comprising obfuscating the DTC; and returning, by the server, the webpage including the ETV and DTC to the client device, the DTC configured to execute upon receipt at the client device and validate the ETV upon executing.

The present disclosure relates to traffic monitoring through one or more access control servers configured configured for (i) routing server resource request messages to resource server(s), (ii) extracting information identifying a target server resource from data packets corresponding to one or more received server resource request messages, and (iii) selectively transmitting the received server resource request message to a resource server. The security server(s) is configured to receive a server resource request message data extracted from a server resource request message and initiate a first security response, wherein the initiated first security response is dependent on analysis of the server resource request message data. Responsive to identifying an indicator of compromise or that an originating terminal corresponding to the server resource request is identified within a blacklist, the first security response comprises non-transmission of at least one server resource request message by the access control server to a resource server.
