IPSec diagnostics/audit tool




Hello there,

does anyone know of or has suggestions for developing an IPSec (ESP only? -
not sure) diagnostics or audit tool?

I was thinking of being able to verify that the traffic you assume is
protected is indeed protected when looked at from the outside. This could be
very valuable for testing and auditing your policy.

For example you could statistically analyse payloads (for encrypted packets
those should be flat, whereas non-encrypted packets should be recognisable)
by using a sniffer (how about snort?). Or check that you really do IKE with
ID protection.

But what else is worth capturing or verifying? I'd be grateful for input and
pointers!

Regards

Dirk
