How is SIEM (Security Information and Event Management) related to IOC (Indicator of Compromise)?
SIEM (Security Information and Event Management) and IOC (Indicator of Compromise) are both key concepts in threat intelligence. An Indicator of Compromise is a piece of forensic data — such as a malicious IP address, domain, URL, file hash, or email address — that signals a system has been compromised or attacked. Security teams use IOCs to detect, block, and investigate threats.
