A system includes identification of a data source of a production environment, the data source storing authentic data, generation of simulated data of the data source, reception of a request for data of the data source from a requesting system in the production environment and, in response to the received request, providing of the simulated data to the requesting system. In some aspects, the simulated data is provided to the requesting system if it is determined that the request is related to an electronic attack, and the authentic data of the data source is provided to the requesting system if it is not determined that the request is related to an electronic attack.

A management system detects a change at the target device. The management system transmits a request message to authorization devices of the authorization users of the multi-user authorization pool to from the authorization users an indication of whether the detected change is approved. The management system receives a plurality of response messages from authorization devices of the multi-user authorization pool indicating whether the detected change is approved by the corresponding authorization user, and based on at least three of the plurality of response messages indicating a disapproval, that the detected change is disapproved. In response to the determination that the change is disapproved, an instruction message is sent to a target managed device to instruct the target managed device to rollback to an earlier state.

A compliance monitor measures metrics regarding one or more managed devices in a network. The compliance monitor generates a log based on the information detected by the measurement trackers and to transmit a report based on the generated log to a recipient. The compliance monitor also initiates one or more security actions based on the one or more measurement trackers indicating that a measured metric exceeds an associated threshold measurement value.

Provided is a process that includes: obtaining, with one or more processors, a set of user-authentication credentials of a plurality of users; accessing, with one or more processors, a repository of breached credentials and determining, with one or more processors, an amount of the obtained set of user-authentication credentials in the repository of breached credentials, wherein the repository includes credentials from a plurality of entities obtained after the entities suffered a breach; and determining, with one or more processors, a score based on the amount of the set of user-authentication credentials in the repository of breached credentials, wherein the score is indicative of effectiveness of cybersecurity practices of the entity and the users associated with the entity.

An intermediary data handler is used in a Secured Data Storage Subsystem (SDSS), to provide a host electrical computer system with security of certain data stored in memory of the computer system's static data storage device. The intermediary data handler is functionally disposed between the operating system (OS) and data storage device of the host computer. The data handler has Processor, Memory, and User Interface circuits, and resident software adapted to generate mocked-up response data in reply to an unauthorized read/write communication from the OS, the mock data response being automatically formatted to have a content and data-structure format acceptable by the host OS, while isolating and controlling the original communication from the OS. The SDSS includes host software adapted to integrate operation and function of the intermediary data handler with the host computer system to accomplish the security of data stored on the storage device.

A system for detecting by a cloud service a ransomware attack on a client device is provided. The system monitors changes to files of the client device that are stored by the cloud service. The system assesses whether a change to a file appears to be malicious in that the change may be caused by ransomware. When the change to the file appears to be malicious, the system performs a countermeasure to prevent synchronization of files of the client device with other client devices and with the cloud service to prevent the propagating of files from the client device, which is undergoing a ransomware attack.

Systems and methods for generating and deploying decoy files and decoy applications that appear to be authentic files and applications. The content of the decoy files may be configurable, and the decoy files may be beaconized. The extent to which decoy files are and decoy applications are deployed may depend on the authentication level or change in authentication level of a user.

Techniques are described for delayed serving of protected content. A request has been made by a client computing device for a requested resource comprising a first portion and a second portion that is initially withheld from the client computing device. First content comprising the first portion of the requested resource and reconnaissance code is served for execution on the client computing device. When executed at the client computing device, the reconnaissance code gathers data at the client computing device that indicates whether the client computing device is human-controlled or bot-controlled. The data gathered by the reconnaissance code is received. Based on the data, it is determined that the client computing device is not bot-controlled. In response to determining that the client computing device is not bot-controlled, the second portion of the requested resource is served to the client computing device,

Generally discussed herein are systems, devices, and methods for determining if a circuit is acting improperly. A system can include a module to receive proper performance values of a circuit, a module to receive improper performance values of the circuit, a module to compare actual circuit input characteristics (X.sub.a) and actual circuit output characteristics (Y.sub.a) to X, Y, D, and Z to determine if the circuit is more likely operating properly or more likely operating improperly, and an alert module to, in response to determining the circuit is operating improperly, provide an alert to personnel indicating that the circuit is operating improperly or providing one or more signals to the circuit that cause the circuit to alter its current operation.

Approaches for managing security breaches in a networked computing environment are provided. A method includes detecting, by at least one computer device, a breach of a production system in the networked computing environment, wherein the networked computing environment includes a decoy system interweaved with the production system. The method also includes receiving, by the at least one computer device, a communication after the detecting the breach. The method further includes determining, by the at least one computer device, the communication is associated with one of a valid user and a malicious user. The method additionally includes, based on the determining, routing the valid user to an element of the production system when the communication is associated with the valid user and routing the malicious user to a corresponding element of the decoy system when the communication is associated with the malicious user.
