SIEM Architecture (Splunk, ELK, QRadar): Centralizing enterprise log data by collecting, parsing, normalizing, and aggregating diverse logs into a single, searchable repository for real-time security analysis.
Log Sources & Telemetry Integration: Collecting and parsing diverse logs to construct system visibility, integrating endpoints via Windows Event Logs (utilizing Sysmon for process-level monitoring), along with firewall, DNS query, and EDR security telemetry.
Detection Engineering (YARA, Sigma): Designing custom detection patterns, writing host-level file identification rules (YARA), and drafting platform-agnostic behavioral analytics signatures (Sigma) for deployment across varied SIEM environments.
Alert Triage & SOC Workflows: Managing security alert lifecycles, establishing structured Tier-1/2 analyst workflows to rapidly separate false positives from true positive intrusions, and escalating verified incidents.
Threat Hunting: Proactively querying enterprise data lakes to identify stealthy, existing compromises by executing hypothesis-driven searches, assuming that traditional automated defenses have already been bypassed.
