Combining powerful open source tools under a unified ecosystem, SELKS offers unparalleled visibility into network threats, ensuring fortified defenses for modern infrastructures.
Core Applications Driving SELKS Excellence
- Suricata – High-performance IDS and IPS engine
- Elasticsearch – Distributed search and analytics engine
- Logstash – Versatile data processing pipeline
- Kibana – Interactive data visualization dashboard
- Scirius – Rules manager and threat hunting interface
Suricata
Suricata serves as the heartbeat of SELKS, capable of inspecting multi-gigabit network traffic in real time. Its multi-threaded architecture unlocks maximum throughput while maintaining low latency.
- Protocol identification for HTTP, TLS, DNS and more
- File extraction and integrity checking using MD5 SHA1 SHA256
- Automatic protocol anomaly detection
- IP reputation and geo-location integration
Elasticsearch
Elasticsearch indexes and stores Suricata events, transforming raw logs into a searchable knowledge base. Its distributed nature scales horizontally to accommodate massive datasets.
- Real-time indexing with near zero-latency search
- Cluster resilience with automated shard replication
- Powerful query DSL for complex threat investigations
Logstash
Logstash orchestrates data ingestion, filtering and forwarding. Tailored filters normalize Suricata output into structured JSON, enriching events with geoip threat indicators.
- Over 200 input and output plugins
- Conditional processing for custom rule sets
- Buffering and backpressure management
Kibana
Kibana transforms indexed events into compelling dashboards. Through interactive charts heat maps and timeline visualizations security teams gain contextual awareness of network anomalies.
- Drag-and-drop dashboard creation
- Canvas presentations for executive reporting
- Alerting and anomaly detection modules
Scirius
Scirius elevates rule management with a user-friendly interface for creating enabling and tuning Suricata rules. Security analysts orchestrate threat hunting campaigns without editing raw YAML or XML.
- Rule versioning with rollback capabilities
- Signature performance metrics
- Integration with Emerging Threats and custom feeds
Additional Luxurious Extensions
- Filebeat – Lightweight log forwarder for endpoint data
- Winlogbeat – Windows event collector with security module
- Grafana – Alternative visualization for time series analytics
- Packetbeat – Network protocol analyzer for transaction monitoring
