Security Monitoring and Threat Detection Questions

Covers the principles and practical design of security monitoring, logging, and threat detection across environments including cloud scale infrastructure. Topics include data collection strategies, centralized logging and storage, security information and event management architecture, pipeline and ingestion design for high volume and high velocity data, retention and indexing tradeoffs, observability and telemetry sources, and alerting and tuning to reduce noise. Detection techniques include signature based detection, anomaly detection, indicators of compromise, behavioral detection, correlation rules, and threat intelligence integration. Also covers evaluation metrics such as false positives and false negatives, detection coverage and lead time, incident escalation, playbook integration with incident response, automation and orchestration for investigation and remediation, and operational concerns such as scalability, cost, reliability, and privacy or compliance constraints.
