Abstract

Techniques and mechanisms are disclosed that enable network security analysts and other users to efficiently conduct network security investigations and to produce useful representations of investigation results. As used herein, a network security investigation generally refers to an analysis by an analyst (or team of analysts) of one or more detected network events that may pose internal and/or external threats to a computer network under management. A network security application provides various interfaces that enable users to create investigation timelines, where the investigation timelines display a collection of events related to a particular network security investigation. A network security application further provides functionality to monitor and log user interactions with the network security application, where particular logged user interactions may also be added to one or more investigation timelines.

10. The method of claim 1, further comprising receiving input selecting one or more user action types to log.

11. The method of claim 1, further comprising receiving input selecting one or more user action types to display in the workflow log view.

12. The method of claim 1, further comprising:

receiving input selecting a particular graphical event indication of a plurality of graphical event indications displayed on a timeline view, the particular graphical event indication corresponding to a particular workflow event of the one or more workflow events; and

in response to receiving the selection of the particular graphical event indication, causing display of the particular workflow event in the workflow log view.

13. The method of claim 1, wherein at least one event of the one or more events corresponds to a detected malware infection, a security access violation, or network traffic.

14. The method of claim 1, further comprising:

receiving input specifying a search string for one or more workflow events;

causing the workflow log view to display one or more workflow event results, each workflow event result of the one or more workflow event results including information matching the search string.

15. The method of claim 1, further comprising:

receiving input specifying an action type filter;

causing the workflow log view to display one or more workflow event results, each workflow event result of the one or more workflow event results including information matching the action type filter.

16. The method of claim 1, further comprising:

receiving input specifying one or more timeframes;

causing the workflow log view to display one or more workflow event results, each workflow event result of the one or more workflow event results is associated with a timestamp matching at least one timeframe of the one or more timeframes.

17. One or more non-transitory computer-readable storage media, storing instructions, which when executed by one or more processors cause performance of:

causing display of a graphical user interface including a plurality of interface elements and an investigative workflow log view, the plurality of interface elements related to one or more events stored by a data intake and query system, the investigative workflow log view displaying one or more investigative workflow events in a timeline view describing prior user interactions with one or more interface elements of the plurality of interface elements while investigating the one or more events;

wherein each event of the one or more events is related to one or more performance characteristics of one or more computing devices;

while causing display of the graphical user interface, receiving an indication of a user interaction with one or more interface elements of the plurality of interface elements, wherein the user interaction is an investigative action performed by a user in response to observing one or more particular events among the one or more events; and
