Re: SSL Inbound Inspection

Hi Team

 

Just to share additional details - 
 
We have nginx web server who acts as a proxy and directs traffic to the server where we have hosted Joomla (CMS).
 
Every website of Joomla (i.e partner website) is SSL with Lets Encrypt. To be precise we have 350+ websites. We recently received attack on these websites which was not detected by Palo Alto, probably due to absence of SSL inbound Inspection.
 
I configure my Nginx server in DMZ and Application server (Joomla) in LAN.
 
Nginx server will decrypt the ssl traffic and transfer through PA firewall to LAN 
 
My question is, Will Firewall can now detect Vulnerabilities?

I'm not familiar with Nginx, but if it's decrypting and NOT re-encrypting the traffic before it sends it on you will be fine.  If the Palo is getting decrypted traffic the firewall will then be able to apply threat signatures to traffic and take action based on policy you've confgiured.
