Security Monitoring and Detection Questions

Design and operate end to end security observability and detection capabilities that enable timely detection, investigation, and response across infrastructure, network, endpoints, and applications. Core design topics include deciding which security events and telemetry to capture, secure and tamper resistant log collection and storage, log aggregation and normalization strategies, telemetry schema design, and integration with security information and event management tooling and endpoint detection and response and threat intelligence. Detection engineering topics include use case and detection rule design, anomaly detection approaches for security telemetry, correlation and centralized analysis, tuning to reduce false positives and alert fatigue, and playbooks for alert triage and incident response. Architecture and scale considerations cover detection pipeline design for high volume telemetry, tiered storage and retention policies, log retention and privacy and compliance requirements, performance and reliability of the monitoring pipeline, and forensic readiness and evidence preservation. Candidates may be evaluated on how they balance detection coverage against false positives, storage and processing cost trade offs, operational overhead for investigations, and how they secure and validate the integrity of the logging and detection systems.
