Background for this topic.
Threat intelligence is analyzed information about adversaries, their capabilities, targets, infrastructure, and methods, used to support security decisions. It can describe broad trends for leadership, likely actors and campaigns for defenders, or actionable details such as malicious domains, file hashes, vulnerabilities, and tactics, techniques, and procedures (TTPs). Practitioners obtain it from internal investigations, public reporting, telemetry, information-sharing communities, and other sources, then assess its reliability, relevance, and age.
Security teams use threat intelligence to prioritize vulnerability remediation, tune detection rules, investigate suspicious activity, and prepare incident-response playbooks. TTP-based intelligence generally remains useful longer than individual indicators, which can become obsolete or be changed by an attacker. Poorly sourced or context-free intelligence can create false positives, waste analyst time, or lead to unjustified attribution and defensive action. Collection and sharing may also expose sensitive organizational or personal information, so access controls, provenance, retention, and applicable privacy or legal requirements matter.
