Question

Suricata IPS not dropping packets, rather just creating alert.

I configured suricata as an IPS by following this tutorial - https://www.digitalocean.com/community/tutorials/how-to-configure-suricata-as-an-intrusion-prevention-system-ips-on-ubuntu-20-04. But the system is not dropping the packets even after I modified the rule woth sid 2100498 from alert to modify in the suricata.rules. yet this is just creating the alert and not dropping the packet when i test it out. Can anyone help me

Hello @zakiscubadiver

You can inspect the local rules file - /var/lib/suricata/rules/local.rules and check if you have any allow rules before the block ones. This might cause a similar experience.

Hope that this helps!
