Threat correlation is a cybersecurity process that involves analyzing and connecting data from multiple sources to identify sophisticated or hidden security threats. By correlating events and alerts from various systems - such as firewalls, intrusion detection systems, and endpoint devices - security teams can detect patterns that may indicate coordinated attacks or advanced persistent threats. This approach enhances threat detection accuracy, reduces false positives, and enables faster response to incidents by providing a comprehensive view of potential security breaches. Threat correlation is essential for modern security operations centers (SOCs) to effectively manage and respond to the increasing complexity of cyber threats.
