Introduction to Cyber Threat Intelligence
Learn the fundamentals of CTI, its processes and types, and why threat intelligence matters in modern cybersecurity.
What is Cyber Threat Intelligence?
Cyber Threat Intelligence (CTI) is a systematic process of collecting, analyzing and disseminating information about current and emerging cyber threats. It helps organizations make informed decisions about their security.
CTI turns raw data into actionable intelligence, enabling a proactive rather than reactive approach to cybersecurity.
The CTI process
Data collection
Gathering threat information from many sources
- External data feeds
- IOCs and TTPs
- Security reports
- Honeypots and sandboxes
Analysis and correlation
Processing and analyzing data to identify patterns
- Behavioral analysis
- Event correlation
- Attack attribution
- Risk assessment
Diffusion
Sharing actionable information with stakeholders
- Intelligence reports
- Real-time alerts
- Executive briefings
- Automated IOCs
Action
Implementing intelligence-driven defensive measures
- IOC blocking
- Signature updates
- Strengthening controls
- Team training
Types of CTI
Tactical Intelligence
Immediately actionable intelligence
Hours to days
SOC teams, analysts
- IOCs
- Signatures
- Detection rules
Operational Intelligence
Intelligence on campaigns and techniques
Weeks to months
Security managers
- TTPs
- Campagnes
- Threat actor groups
Strategic Intelligence
Long-term trends and developments
Months to years
Leadership, CISO
- Threat trends
- Cyber geopolitics
- Investissements
Benefits of CTI
Better detection
Earlier, more accurate threat detection
Fewer false positives
Richer context for better prioritization
Proactive response
Anticipating threats before they materialize
Informed decisions
Facts to back security decisions
Key concepts
Indicators of Compromise (IOCs)
Forensic evidence of a potential intrusion on a system, such as file hashes, IP addresses or malicious domains.
Tactics, Techniques, Procedures (TTPs)
Behaviors and methods used by attackers, often referenced in the MITRE ATT&CK framework.
Threat Actors
Individuals or groups behind malicious activity, categorized by motivation, capability and origin.
Attribution
The process of identifying who is behind an attack, based on analysis of TTPs and other evidence.
