Virtual CISO. Digital Forensics. Steps to Configure SSL Decryption 1. Now, provide a Friendly Name for this certificate. Details The following show system setting ssl-decrypt commands provide information about the SSL-decryption on the Palo Alto Networks device: Show the list of ssl-decrypt certificates loaded on the dataplane > show system setting ssl-decrypt certificate If your webserver goes down, the firewall will cache the last copy of the edl it had until it recovers. NGFWs can see and decrypt traffic on all ports, providing visibility into all applications, users, content and threats. This seems to be causing an issue with the installation of Sophos Intercept-X as it would seems it uses an untrusted certificate. Perfect Forward Secrecy (PFS) Support for SSL Decryption . Palo Alto Networks Predefined Decryption Exclusions. SSL Decryption for Elliptical Curve Cryptography (ECC) Certificates. Decrypted traffic is stored in memory and not sent to other devices. Expert Malware Analysis. In this session, you will: Hear about recent innovations in PAN-OS 9.0 that help customers streamline SSL Decryption best practices. For SSL traffic PA uses the CN or SNI on the cert to identify the 'URL'. Register or Sign-in to Engage, Share, and Learn. PAN-OS can decrypt and inspect SSL inbound and outbound connections going through the firewall.
