Training program

Module 1Snort Installation: Initial Deployment and Basic Configuration (Linux Tools, Preprocessors)

Dive into quick Snort installation on Ubuntu, configure network interfaces, enable essential preprocessors like HTTP and DNS, test packet capture with tcpdump, complete your first verification exercises, generate initial reports to validate proper functioning, and prepare the environment for advanced rules, with personalized feedback for immediate mastery.

Module 2Snort Rules: Writing and Custom Signatures (Rules, Patterns, Actions)

Learn to write precise Snort rules to detect SQLi and XSS, test them on simulated traffic flows with tcpreplay, adjust alert thresholds, integrate variables and includes, analyze performance with SnortStat, produce custom signatures for your IT system, and iterate in groups on real cases to boost your proactive detection expertise.

Module 3Snort Analysis and Logging: Decrypting Alerts (Output Plugins, Unified2)

Explore unified2 and barnyard2 logs, configure outputs to Syslog and JSON, use Wireshark to correlate suspicious packets, simulate DDoS and malware attacks, decrypt SIDs and classifications, generate dashboards with ELK, and practice forensic analysis on real scenarios, turning every alert into concrete action to strengthen your network vigilance.

Module 4Snort Integration: Tuning and SIEM (ELK, Suricata-like, Performance)

Integrate Snort with the ELK Stack to visualize threats in real time, optimize rules with thresholds and suppression to minimize false positives, benchmark performance on multi-core systems, configure inline IPS mode, test HA with Keepalived, and deploy automated playbooks, making your IDS scalable and enterprise-ready.

Module 5Advanced Snort Deployment: Production Scenarios and Final Exercises (HA, Monitoring)

Deploy Snort in a high-availability cluster, monitor with Prometheus and Grafana, simulate MITRE ATT&CK breaches, write an incident response plan, test resilience against evasions, produce a complete configuration deliverable, and conclude with a defensive hack challenge, arming you to effectively protect your critical infrastructures.
