Defining Operational Intelligence

Operational intelligence focuses on current threat activities and provides context for threat detection, investigation, and response activities.

Key Characteristics

Operational intelligence is distinguished by several core attributes:

• Campaign-Focused: Examines specific adversary operations rather than general techniques
• Context-Rich: Provides the “who” and “why” behind observed technical indicators
• Timely: Delivers intelligence within operational decision windows
• Specific: Addresses particular threats rather than broad categories
• Near-Term: Typically relevant over days to weeks
• Detection-Oriented: Directly supports monitoring and alerting activities
• Response-Informing: Provides context for incident investigation and remediation
