Cyber Threat Intelligence (CTI) is the process of producing contextual information about threat actors that may affect organizations, technical indicators (IOC/TTP), attack methods, and threat trends. This information is used for proactive defense against attacks, reducing the threat surface, and supporting security decision-making.
The CTI process consists of collection, analysis, enrichment, correlation, reporting, and action steps.
Proactive Security: Enables identifying threats and taking action before an attack occurs.
Protection Against APT and Targeted Attacks: Defense strategies are developed by analyzing the TTPs of organized threat actors.
IOC & TTP Richness: Provides technical indicators for anomaly detection and feeding EDR/SIEM systems.
Contribution to Incident Response Process: Intelligence-fed incident response plans are executed more quickly and effectively.
Supports Managerial Decisions: Facilitates risk-based investment by presenting a threat panorama for senior decision-makers.
Contribution to Regulatory Compliance: Regulations such as ISO 27001, NIS2, DORA have now made CTI processes mandatory or recommended.
Institution-Specific Threat Modeling: Threat modeling is conducted based on assets, sectors, and threat actors (aligned with MITRE ATT&CK).
Identification of Intelligence Sources: OSINT, dark web, partner data streams, honeypots, forums, STIX/TAXII feeds are selected.
Data Collection and Filtering: High-accuracy IOC/TTP data is collected, free from noise.
Analysis and Correlation: Threat data is correlated with internal incidents and integrated into SIEM/EDR systems.
Reporting and Actioning: Threat bulletins, trend analyses, and urgent actions are provided at both technical and managerial levels.
Process Improvement & Continuous Updating: Adaptive analysis and up-to-date data flow are ensured against new threats.
Threat Intelligence Strategy and Program Development: CTI configuration suitable for the institution's sector, size, and maturity level.
IOC and TTP Feeding Services: Collection of technical indicators such as domain name, IP, file hash, URL, behavioral signatures, and sharing with SIEM/EDR.
Dark Web and Private Forum Monitoring: Detection of credentials, organization brand, customer data, and other leaks.
MITRE ATT&CK Based Threat Mapping: Correlating incidents with the tactics and techniques of threat actors.
Sectoral Threat Intelligence: Analysis of threat actors and trend reports specific to sectors such as finance, health, energy, and public services.
CTI Platform Selection and Integration: Selection, installation, and management of platforms such as MISP, ThreatConnect, Recorded Future, Anomali.
CTI Supported Incident Response Consulting: Effective use of threat intelligence in incident interventions.
CTI Trainings for Managers & SOC Team: Role-based intelligence training, technical literacy, and tactical decision support.
