Cyber threat intelligence works by systematically gathering and analyzing data from various sources to identify potential cyber threats and vulnerabilities. The process typically involves four key stages:
- Collection: Raw data is gathered from internal sources (like firewalls, logs, and sensors) and external sources (like threat feeds, dark web monitoring, and open-source intelligence).
- Processing: The collected data is organized and filtered to remove irrelevant or duplicate information, making it easier to analyze.
- Analysis: Security analysts or automated systems examine the processed data to detect patterns, identify potential threats, understand attacker behavior, and assess the level of risk.
- Dissemination: The resulting insights are shared with relevant teams or tools (like SIEMs or firewalls) so that appropriate defensive actions can be taken, such as blocking malicious IPs, patching vulnerabilities, or adjusting security policies.
Overall, cyber threat intelligence turns raw information into actionable insights, helping organizations detect threats early, understand attack motives, and improve their security posture.
