Short Summary

The video discusses the process of building CTIC (Suricata) from source, enabling rule profiling to analyze rule performance. The presenter guides viewers through the installation steps on Ubuntu, emphasizing the necessary commands and configurations needed to successfully set up the software for rule writing and troubleshooting.

Key Points

• Introduction to building CTIC from source with rule profiling enabled.
• Compilation of Sarot is required for enabling rule profiling to gain insights into rule performance.
• Installation process begins with acquiring necessary packages on Ubuntu.
• Advice to run installation commands as a non-root user to avoid permissions issues.
