Abstract: A lateral movement application identifies lateral movement (LM) candidates that potentially represent a security threat. Security platforms generate event data when performing security-related functions, such as authenticating a user account. The disclosed technology enables greatly increased accuracy identification of lateral movement (LM) candidates by, for example, refining a population of LM candidates based on an analysis of a time constrained graph in which nodes represent entities, and edges between nodes represent a time sequence of login or other association activities between the entities. The graph is created based on an analysis of the event data, including time sequences of the event data.

Abstract: A system and method of obtaining and utilizing an activity signature that is representative of a specific category of network activities based on directory service (DS) log data. The activity signature may be determining by a learning process, including segmenting and pruning a training dataset into a plurality of event segments and matching them with activities based on DS log data of known activities. Once obtained, the activity signature can advantageously be utilized to analyze any DS log data and activities in actual deployment. Using activity signatures to analyze DS event log can reveal roles of event-collection machines, aggregate information dispersed across their component events to reveal actors involved in particular AD activities, augment visibility of DS by enabling various vantage points to better infer activities at other domain machines, and reveal macro activities so that logged information becomes easily interpretable to human analysts.

Abstract: A device may determine a link master/slave relationship for an Ethernet link associated with a connection between a component of the device and a component of another device. The device may determine that Synchronous Ethernet (SyncE) is to be enabled on the Ethernet link. The device may identify the component of the device as a SyncE slave or a SyncE master associated with enabling SyncE on the Ethernet link. The device may provide an indication that the component of the device has been identified as the SyncE slave or the SyncE master. The device may determine a SyncE master/slave relationship associated with enabling SyncE on the Ethernet link. The SyncE master/slave relationship may supersede the link master/slave relationship without altering the link master/slave relationship. The device may cause the component of the device to recover a clock based on the SyncE master/slave relationship rather than the link master/slave relationship.

Abstract: A first device may provide, to a second device, a first message that includes a first request for a first type of precision time protocol (PTP) message and a second request for a second type of PTP message. The first device may receive, from the second device, a second message based on the first message. The second message may identify whether the first request and the second request are granted. The first device may provide, to the second device, a third message that instructs the second device to provide a first set of messages, associated with the first type of PTP message, and a second set of messages associated with the second type of PTP message. The first device may synchronize a first clock of the first device with a second clock of the second device based on the first set of messages and the second set of messages.

Abstract: According to an example, pre-cognitive SIEM may include using trained classifiers to detect an anomaly in input events, and generating a predictive attack graph based on the detected anomaly in the input events. The predictive attack graph may provide an indication of different paths that can be taken from an asset that is related to the detected anomaly to compromise other selected assets in a network of the asset, and the other selected assets may be selected based on a ranking criterion and a complexity criterion. A rank list and a complexity list may be generated. The rank list, the complexity list, a depth of the predictive attack graph, and a weighted value may be used to generate a score that provides an indication of a number of assets that can be compromised and a difficulty of exploiting vulnerabilities related to services of the assets that can be compromised.

Abstract: A plank (10) used to construct a platform such as a catwalk (C3, C4) extending about the exterior or interior of a building (B) includes first and second generally horizontal sections (12, 22). The second generally horizontal section of the plank extends from one side of the first section. During construction of the platform, the first section of one plank overlaps the second section of an adjacent plank. A third generally vertical section (52) of the plank extends generally perpendicularly from one side of the second section and includes lips (58, 60) at its inner and outer ends for attaching the plank to toe boards (40, 44) to secure the plank to the frames. When installed, the planks extend from a side of the building. The resulting catwalk extends either in a straight line, or is curved, depending upon the amount of overlap the first and second sections of the respective planks.

Abstract: Provided is a method of symbol-based merging of computer programs. A source program file and a destination program file, wherein the source file is a later generated version of the destination program file, is parsed to identify symbols present in the source program file and the destination program file. A mapping of the symbols present in the source program file and the destination program file is generated. From the mapping, symbols that were modified, added or deleted in the source program file since it was generated from the destination program file are identified. The identified symbols are merged.

Abstract: An I/O adapter is installed in a slot in a computer system. Online deletion of the I/O adapter is achieved by a three step process, in which a device driver that controls the adapter first attempts to quiesce the adapter, the slot is then powered off, if it is possible to do so, and finally, if the quiesce operation was successful or the slot is powered off, the driver completes the delete operation by unmapping buffers and cleaning up datastructures associated with the device driver.
