Step 5: Download and Update Suricata Rules 📄
Suricata uses rules to detect potential threats. Keeping these rules up to date is crucial.

sudo suricata -c /etc/suricata/suricata.yaml --af-packet=eth0Step 7: Test the Installation 🧪
Test Suricata by generating some network traffic. Use nmap or another tool to initiate traffic that should trigger alerts.
nmap -sS -Pn -p 80,443 <target-ip>
Check the logs:
