Threat intelligence involves collecting, analyzing, and applying information about emerging cyber threats to enhance security defenses. It helps organizations understand attack patterns, threat actors, and vulnerabilities to proactively mitigate risks. Threat intelligence is categorized into strategic (high-level insights), tactical (attack methods and tools), and operational (real-time threat data). By leveraging threat intelligence, businesses can anticipate cyber threats, strengthen security strategies, and respond effectively to potential attacks, reducing the risk of breaches and system compromises.
