UNCLASSIFEDWhat You Need to Know Define Cyber Threat Framework Recognize the benefits of using standardized language todescribe cyber activity and enable consistent categorization Understand the Cyber Threat Framework hierarchy and itsfour layers of information Understand how the Cyber Threat Framework can be used tosupport analysis1/30/2017ODNI Public Affairs Office3

UNCLASSIFEDCyber Threat Framework (CTF) OverviewThe Cyber Threat Framework was developed by the US Government toenable consistent characterization and categorization of cyber threat events,and to identify trends or changes in the activities of cyber adversaries. Theframework captures the adversary life cycle from (a) “PREPARATION” ofcapabilities and targeting to (b) initial “ENGAGEMENT” with the targets ortemporary nonintrusive disruptions by the adversary to (c) establishing andexpanding the “PRESENCE” on target networks, to (d) the creation of“EFFECTS and CONSEQUENCES” from theft, manipulation, or disruption. Theframework categorizes the activity in increasing “layers” of detail (1- 4) asavailable in the intelligence reporting.1/30/2017ODNI Public Affairs Office4

UNCLASSIFEDThere are many cyber threat models orframeworks – why build another? Began as a construct to enhance data-sharing throughout the USGovernment Facilitates efficient situational analysis based on objective (typically,sensor-derived) data Provides a simple, yet flexible, collaborative way of characterizing andcategorizing activity that supports analysis, senior-level decision making,and cybersecurity Offers a common backbone (‘cyber Esperanto’); easier to map uniquemodels to a common standard than to each other Facilitates cyber threat trend and gap analysis, and assessment ofcollection posture1/30/2017ODNI Public Affairs Office5

UNCLASSIFEDMerging Disparate Data Layers into a CommonFramework is a Standard Practice Weather – overlaying satellite (clouds), doppler (rain), and thermometer(temperature) data atop a map yields a forecast: “take your umbrella andwear a light coat” Air Traffic Control – integrating weather, regional/ground control radars,scheduling data, aircraft/ground handler status to control air traffic: “youare cleared to land” In a similar fashion, a cyber threat framework based on measurable datafacilitates visualization, analysis, and realization of a Common OperatingPicture of threat activity It can also be matched with other data layers (e.g., vulnerability, sharedconnections) to become more actionable1/30/2017ODNI Public Affairs Office6

UNCLASSIFEDConsumer Needs Dictate Perspective and Content The foundation, based on empirical data, is the commonreference point for all subsequent views– The consumer provides the focus by defining the view and/or adjustingthe type of content (actor, activity, targeted sector, and victim)– The consumer defines the required granularity in each view but can“drill down” to see the underlying detail as desired The framework is applicable to a range of threat actors,activity, targeted sectors, and victims1/30/2017ODNI Public Affairs Office17

UNCLASSIFEDAnalysis Depending on the information selected and its presentation,one can begin to conduct a variety of analysis:– Trends – change over time What caused the change– Predictive – what’s next– Environmental Was the threat different than expected What vulnerabilities were missed How to optimize remedial action– Vulnerability – risk analysis– Defensive posture1/30/2017ODNI Public Affairs Office18
