Bethesda, Md. – Threat hunters still disagree on what constitutes threat hunting and how to hunt, according to the results of the SANS 2019 Threat Hunting Survey to be released by SANS Institute in two webcasts: the results webcast on October 29, 2019, and a panel discussion of results on October 30, 2019 at 1 PM Eastern.
“Many organizations use an alert-driven approach to threat hunting or use indicators of compromise [IoCs] to guide their hunts,” says Mathias Fuchs, a SANS instructor and co-author of the survey. “It seems that fewer organizations are using hypothesis-driven hunting—and that could leave them vulnerable to dangerous visibility gaps.”
Most respondents report using a variety of reactive approaches to threat hunting, including alerts (40%) or IoCs via a SIEM or other alerting system to find adversary tools or artifacts (57%). Such approaches are excellent supplements, but should not take the place of using proactive hunting techniques. Surprisingly, only 35% of respondents create hypotheses to guide their hunting activities.
Organizations continue to require threat hunters to work in multiple roles. Hunters report having major responsibilities for managing SOC alerts (34%) or IR and forensics of breaches (26%). Very few organizations have moved to a dedicated hunt team over the past three surveys, indicating that threat hunting—and threat hunting teams—are in their infancy.
“One reason we aren’t seeing more growth in dedicated threat hunting teams may be that organizations have difficulty measuring the benefits or organizational impact of threat hunting,” posits Josh Lemon, survey co-author and SANS instructor. “Being able to measure and show the performance abilities of a threat hunting team is critical to the life of a team and its engagement by the rest of the business; it's a metric that can make or break a team, its funding or its objectives.”
While 24% of respondents were unable to determine whether they had measurable improvements as a result of threat hunting, 61% reported having at least an 11% improvement in their overall security posture. Organizations have seen a marked improvement in more robust detections and better coverage across the environment, with 36% claiming significant improvement and another 53% realizing some improvement. Other key improvements are attack surface exposure/hardened networks and endpoints, with 35% seeing significant improvement and 58% seeing some improvement, and more accurate detections and fewer false positives, at 32% significant improvement and 51% some improvement.
Full results will be shared during an October 29, 2019, webcast at 1 PM EDT, sponsored by Anomali, Authentic8, CarbonBlack, DomainTools, ExtraHop, Lastline, Sophos, ThreatConnect, ThreatQuotient, and Verodin, and hosted by SANS. Register to attend the webcast at https://www.sans.org/webcasts/111010
The authors and representatives from DomainTools, ExtraHop and ThreatConnect dig deeper into the results in a panel discussion on October 30, 2019, at 1 PM EDT. Register to attend that webcast at https://www.sans.org/webcasts/111015
Those who register for either webcast will also receive access to the published results paper developed by SANS analysts, instructors and threat hunting experts Mathias Fuchs and Josh Lemon.
