PROFILE
Emil
Emil Andreelset Ronning contributed to the splunk/security_content repository by developing and refining security detection features over a three-month period. He enhanced horizontal port scan detection by optimizing SPL queries and restructuring logic to leverage tstats, which improved both performance and triage efficiency. Emil also improved risk messaging for LOLBAS and Mshta-based detections, adding process context and standardizing message formats to support faster, more accurate incident response. His work involved YAML configuration, data modeling, and security analysis, with a focus on maintainability and clarity. These contributions reduced false positives, streamlined triage, and strengthened the reliability of detection logic.

Jan 1, 2026January 2026 monthly summary for splunk/security_content. Delivered the Enhanced Risk Messaging for LOLBAS Detection feature, improving detection clarity and incident response by including the process_name in risk_message and enforcing consistent message formatting. This change enhances telemetry accuracy, supports faster triage, and reduces ambiguity in LOLBAS activity. The work includes version/date metadata bump and standardization of threat_object as the process, with co-authored contributions from Nasreddine Bencherchali and Bhavin Patel. Reference commit 9c9482bfb960962bba8528d417553f7ae0a2e642 and related notes in PR #3874.

Dec 1, 2025Month 2025-12: Delivered enhanced horizontal port scan detection improvements for splunk/security_content with a focus on performance and triage usability. The work refactors the query path to push more logic into tstats, adds new triage-friendly fields (including lastTime), and updates YAML configuration with versioning and metadata to clarify configuration. Also introduced an All_Traffic.rule to satisfy validation requirements and improve reliability during validation. No major bug fixes recorded this month for this repository. Overall impact: faster, more accurate detection of horizontal port scans, streamlined triage, and improved configuration reproducibility and validation readiness.
