 Defensive Measures
 ==================
 
-This section outlines the key components that have been identified for the Defensive Measures dimension as well as maturity levels within the components. These components and 
-levels form the basis for assessing how threat informed an organization’s Defensive program is. This assessment can be conducted using the companion spreadsheet published with 
-this white paper.

 3. Compliant with best practices for network and devices (e.g., logs collected from each device according to the manufacturer’s recommendations)

 Incident Response

 3. Playbook-enabled, partially automated

+4. Informed by knowledge of threat actor (e.g., initial detection leads to follow-on investigation to detect other malicious actions expected in the campaign based on CTI) Proactive hunts are conducted driven by threat information rather than only alerts from existing analytics.
 5. Strategic, holistic, optimized to deter future events (e.g., with an understanding of the full campaign and the adversary’s likely reaction to defensive response, the defenders take decisive and coordinated actions that effectively evict the adversary such that it is not easy for them to return)  
 
 
 Deception Operations [#f8]_
 ---------------------------------
