SSL Decryption Inbound Inspection

L1 Bithead

On AWS we have deployed Application Load balancer after firewall. Can we configure ssl inbound inspection in this case?

Will it work properly, whic certificate we have to import on firewall, server certificate or ALB certificate?

Yes, you can decrypt on the ALB to perform any URI-based policy or insert the XFF.  You can choose to keep the traffic decrypted behind the ALB and the firewall will see the clear text traffic or reencrypt on the ALB and use inbound SSL decryption.  Typically you would use the same cert for the ALB, backend, and firewall.  At the time of this posting, the ALB does not care about mismatched certs so you could actually use a self-signed cert on the firewall.

In SSL inbound inspection , will self signed certificate work or we would require server certificate?
