The term “Cyber Threat Intelligence” (CTI) refers to the structured process of collecting, analyzing, and disseminating information about current and emerging cyber threats, adversaries, and their tactics, techniques, and procedures (TTPs). The objective is to transform raw data (e.g., logs, threat feeds, open-source information, dark web sources) into actionable, contextualized knowledge that enables organizations to detect attacks earlier, prioritize risks, and plan or automatically trigger appropriate defensive and response measures.:contentReference[oaicite:1]{index=1}
Threat data feeds and source integration: Integration and management of multiple threat sources (e.g., commercial feeds, open-source intelligence, ISAC feeds, dark web sources).
Data normalization and enrichment: Automated cleansing, normalization, and enrichment of threat data (e.g., mapping to TTPs, referencing MITRE ATT&CK, geolocation, industry context).
Indicator management (IoC lifecycle): Managing indicators of compromise (e.g., IPs, domains, hashes, URLs), including import, deduplication, expiration, prioritization, and scoring.
Standards support (e.g., STIX/TAXII): Standards-based exchange of threat information with other systems such as SIEM, EDR, firewalls, SOAR platforms, or external partners.
Correlation and analytics: Correlating threat data with internal logs and alerts, performing pivoting, link and graph analysis, and identifying campaigns and attack patterns.
Contextualization and risk scoring: Assessing the relevance of a threat in terms of industry, region, technology stack, and business-critical assets, including quantitative risk scores.
Integration into SOC workflows: Enriching SIEM alerts, supporting incident response processes, and passing information to SOAR platforms for semi- or fully automated response actions.
Real-time alerting and early warning: Notifying security teams about new campaigns, zero-day exploits, or sector-specific threats that may impact the organization’s environment.
Reporting and dashboards: Providing detailed technical reports for analysts and high-level management reports with aggregated metrics on the threat landscape and control effectiveness.
Knowledge base and case management: Documenting incidents, lessons learned, known threat actors, and reusable playbooks to support continuous improvement.
A Security Operations Center (SOC) enriches SIEM alerts with CTI data to quickly identify malicious IP addresses, domains, and file hashes and to reduce false positives.
A financial services company uses CTI to detect and block targeted phishing and spear-phishing campaigns aimed at executives and payment processes.
An industrial company leverages CTI to monitor sector-specific threats against OT/ICS environments and uses this insight to prioritize patching and network segmentation.
A managed security service provider (MSSP) uses a CTI platform to continuously compare customer environments with global threat data and to drive automated SOAR playbooks.
A global enterprise builds regular cyber threat landscape reports based on CTI to justify security investments and budget decisions to executive leadership.
