Key Characteristics
Threat Intelligence is evidence-based knowledge about existing or emerging threats to assets that can be used to inform decisions regarding the response to those threats. It involves collecting, analyzing, and interpreting data about potential or current attacks that threaten an organization's assets, resources, or operations.
Threat intelligence goes beyond simple security alerts by providing context, source information, and actionable insights about threats. It typically includes information about threat actors, their tactics, techniques, and procedures (TTPs), indicators of compromise (IOCs), and potential targets. Threat intelligence can be categorized as strategic, tactical, operational, or technical based on the intended audience and use case.
Advantages
- Proactive Defense: Enables organizations to prepare for and defend against threats before they materialize
- Contextual Awareness: Provides context about threats, including threat actors, motivations, and methods
- Improved Response: Enhances incident response capabilities with detailed information about threats
- Risk Reduction: Helps reduce security risks by understanding threat landscapes and potential targets
- Resource Optimization: Allows organizations to prioritize security resources based on actual threats

- Strategic Planning: Informs strategic security planning and investment decisions
Disadvantages
- Information Overload: Can generate large volumes of data that may overwhelm security teams
- Quality Issues: Quality of threat intelligence can vary significantly between sources
- Timeliness: Threat intelligence may become outdated quickly as threat landscapes evolve
- Integration Complexity: Integrating threat intelligence into existing security tools can be complex
- Cost: High-quality threat intelligence services can be expensive
