Description

Hello. is it possible to implement in the suricata for it to read the SSLProxy header to get the source and destination correctly?

UTMFW supports the deep SSL inspection of HTTP, POP3, and SMTP protocols. SSL / TLS encrypted traffic is decrypted by SSLproxy and fed into the UTM services: Web Filter, HTTP Proxy, POP3 Proxy, SMTP Proxy, Virus Scanner, Spam Filter, and Inline IPS.

A sample line SSLproxy inserts into the first packet in the connection is the following:

SSLproxy: [127.0.0.1]:34649,[192.168.3.24]:47286,[192.168.111.130]:443,s

Header HTTPS Connection:

GET /pagead/gen_204?id=wfocus&gqid&qqid=CLPmw9v5vNsCFdZHhgod9kUO1A&fg=1 HTTP/1.1
SSLproxy: [127.0.0.1]:31165,[172.16.103.11]:45466,[172.217.30.2]:443,s
