[Twisted-Python] connectionMade, TLS and DoS protection timeouts

[Tobias Oberstein]

I was wondering how I could protect a Twisted server from evil clients initiating,
but never completing a TLS handshake.

connectionMade is only called when the TLS handshake has completed, right?

When doing listenSSL, is there a hook which is fired right after the TCP handshake is
complete, before the TLS handshake begins, so that I can setup a callLater/dropConnection
timeout?

This is the piece I am missing, since for TCP-level protection (Syn floods etc), I can
use kernel parameters / kernel packet filtering, and for app-level protection
(I do WebSockets .. which also has a handshake) I can timeout that.

I like to do above without requiring a frontend TLS terminator / firewall ..

Thanks!
