<p>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.<o:p></o:p></p>
<p>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.<o:p></o:p></p>
<p>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 engineering. <o:p></o:p></p>
