[Oisf-users] Suricata as a Web Firewall.

This is just my opinion, but I'm a fan of 'defense-in-depth', so my
general model is to put your 'active' security controls in first (like a
WAF); then use suricata to monitor how well they are working.

So I would use NGINX as a reverse-proxy/SSL terminator and the put
something like Apache with mod_security behind it, with suricata
monitoring the decrypted traffic.  Do one thing and do it well.

In general I do not like the 'IPS' model given how common
false-positives are, combined with a simple core belief that we should
be building robust software stacks, systems and networks vs. putting
digital duct-tape on the wire.  That strikes me as simple sloppy
