Cyber Threat Intelligence
What is Cyber Threat Intelligence?
Cyber Threat Intelligence (CTI) is the collection, analysis, and application of information about current and emerging cybersecurity threats to help organizations make informed decisions about their defenses and responses. CTI transforms raw threat data, indicators of compromise (IoCs), attacker tactics, techniques, and procedures (TTPs), and vulnerability intelligence into actionable insights that security teams can act on.
The distinction between data and intelligence is important: raw threat feeds provide data. CTI provides analyzed, contextualized, and prioritized information about threats that are specifically relevant to an organization’s environment, industry, and risk profile.
Types of Cyber Threat Intelligence
Strategic Intelligence
High-level analysis of the threat landscape for executive and board audiences: which threat actor groups are targeting the organization’s industry, what their motivations are, and what trends are likely to affect the organization’s risk profile. Strategic CTI informs security investment decisions and risk governance.
Tactical Intelligence
Information about attacker tactics, techniques, and procedures (TTPs), typically described using the MITRE ATT&CK framework. Tactical intelligence helps security teams understand how adversaries operate and adjust detection and prevention controls accordingly.
Operational Intelligence
Information about specific active threat campaigns, including the infrastructure attackers are using and the targets they are pursuing. Operational CTI enables proactive defensive action against campaigns that may be directed at the organization.
Technical Intelligence
Specific indicators of compromise: IP addresses, domain names, file hashes, and email headers associated with known malicious activity. Technical intelligence is consumed directly by security tools for automated blocking and detection.
Applying CTI to Improve Security Posture
CTI is most valuable when it is integrated into security operations workflows rather than treated as a standalone reporting activity. Threat intelligence feeds ingested into SIEM platforms enable automated detection of known malicious indicators. Threat actor profiling informs penetration testing scenarios. Vulnerability intelligence prioritizes patching based on active exploitation evidence rather than CVSS score alone.
Key Takeaways
- Cyber Threat Intelligence transforms raw threat data into actionable, contextualized information relevant to an organization's specific risk profile.
- The four types are strategic (executive-level trends), tactical (attacker TTPs), operational (active campaigns), and technical (IoCs for automated tooling).
- CTI is most effective when integrated into security operations workflows rather than consumed as standalone reporting.
- The MITRE ATT&CK framework provides a common taxonomy for describing and sharing adversary tactics and techniques.
- Effective CTI reduces response time by providing context that helps security teams prioritize the most relevant threats.
