A system for detecting and mitigating forged authentication object attacks is provided, comprising an authentication object inspector configured to observe a new authentication object generated by an identity provider, and retrieve the new authentication object; and a hashing engine configured to retrieve the new authentication object from the authentication object inspector, calculate a cryptographic hash for the new authentication object, and store the cryptographic hash for the new authentication object in a data store; wherein subsequent access requests accompanied by authentication objects are validated by comparing hashes for each authentication object to previous generated hashes.

Network security tool

A system includes a memory, a survey engine, and a reporting engine. The memory stores identifying information of a plurality of users. The survey engine determines a question to present to each user of the plurality of users and determines an interval for each user of the plurality of users. The determined interval for a first user of the plurality of users is different from the determined interval for a second user of the plurality of users. For each user, the survey engine communicates to that user, based on the stored identifying information, the determined question for that user according to the determined interval for that user and receives a response from each user of the plurality of users. The reporting engine generates a report based on the received response from the plurality of users.

System and methods are described for efficient monitoring of network traffic in a public cloud computing environment. In one implementation, a method comprises: generating flow log records of network traffic in the public cloud computing environment; identifying a data packet that presents a potential security risk; identifying a captured data packet (PCAP) record corresponding to the identified data packet; and transmitting the PCAP record to a computing device for network traffic analysis.

Dysfunctional device detection tool

Embodiments of the present disclosure provide systems, methods, and non-transitory computer storage media for detecting abnormal behavior of device in an enterprise network based on an analysis of behavioral information of the device's neighbors in network. At a high level, embodiments of the present disclosure employ a hive-mind approach to determine anomalous behavior of a device in a network based on analyzing behavior information reported by neighboring devices within the network. Embodiments identify that a device is alive and connected within the network based on multiple neighboring devices reporting behavioral information about the device; however, the device may be dysfunctional and failing to report its own information. By aggregating and analyzing behavioral information of a device based on the reporting information of its neighboring devices, embodiments of the present disclosure are able to determine whether a device is healthy even when the device is unable to report its own information.

Cloud access security broker systems and methods via a distributed worker pool

A Cloud Access Security Broker (CASB) system includes a controller; a message broker connected to the controller; and a plurality of workers connected to the message broker and connected to one or more cloud providers having a plurality of files contained therein for one or more tenants, wherein the plurality of workers are configured to crawl through the plurality of files for the one or more tenants, based on policy and configuration for the one or more tenants provided via the controller, and based on assignments from the message broker. The plurality of workers can be further configured to cause an action in the one or more cloud providers based on the crawl and based on the policy and the configuration. The action can include any of allowing a file, deleting a file, quarantining a file, and providing a notification.

Determining multiple ways for compromising a network node in a penetration testing campaign

Methods and systems for penetration testing of a networked system involve assigning network nodes to disjoint classes based on current information about the compromisability of the network nodes. The classes distinguish between nodes not currently known to be compromisable, nodes that only recently have become known to be compromisable, e.g., by a first method of a attack, and nodes that have been known for a longer time to be compromisable. Nodes that only recently have become known to be compromisable can be re-targeted by the penetration testing system to determine whether such nodes can be compromised using multiple methods of attack and not just using the first method of attack.

Computer-implemented method of security-related control or configuration of a digital system

A computer-implemented method includes: receiving system information data representing configurations of digital systems; receiving attack information data associated one or more of the digital systems; analyzing the received system information data and attack information data, to associated attack types; identifying, for each identified attack type, correlations and/or causalities between individual system constituents or combinations thereof in the digital systems associated with attacks; determining and assigning, based on the identified correlations and/or causalities, an attack vulnerability value, for each attack, respectively, to each of the systems and/or systems' constituents and/or combinations thereof; and retrievably storing attack vulnerability values associated with the systems, system constituents and/or combinations thereof.
