Potentially Adverse Event Analysis
DE.AE-02: Potentially adverse events are analyzed to better understand associated activities
  • Ex1:  Use security information and event management (SIEM) or other tools to continuously monitor log events for known malicious and suspicious activity
  • Ex2:  Utilize up-to-date cyber threat intelligence in log analysis tools to improve detection accuracy and characterize threat actors, their methods, and indicators of compromise
  • Ex3:  Regularly conduct manual reviews of log events for technologies that cannot be sufficiently monitored through automation
  • Ex4:  Use log analysis tools to generate reports on their findings
Tier
Not Applicable - Not applicable
No - The outcome(s) have not been meaningfully implemented.
Tier 1: Partial - Application of the organizational cybersecurity risk strategy is managed in an ad hoc manner. Prioritization is ad hoc and not formally based on objectives or threat environment.
Tier 2: Risk Informed - Risk management practices are approved by management but may not be established as organization-wide policy. The prioritization of cybersecurity activities and protection needs is directly informed by organizational risk objectives, the threat environment, or business/mission requirements.
Tier 3: Repeatable - The organization’s risk management practices are formally approved and expressed as policy. Risk-informed policies, processes, and procedures are defined, implemented as intended, and reviewed. Organizational cybersecurity practices are regularly updated based on the application of risk management processes to changes in business/mission requirements, threats, and technological landscape.
Tier 4: Adaptive - There is an organization-wide approach to managing cybersecurity risks that uses risk-informed policies, processes, and procedures to address potential cybersecurity events.
