SPIT (SPam Over Internet Telephony)

The animated TECHTip Tutorial is available here.

Since this tutorial focuses on VoIP Security, please see other TECHtionary tutorials on IP Security or SS7.

In VoIP security, there are two primary network issues - Signaling Path and Media Path. The Signaling Path comes from control of TCP [Transmission Control Protocol] issues explained next. Media Path control comes from protection of the conversation contained in IP [Internet Protocol] packets. Spam or SPIT hackers can attack either the Signaling Path or Media Path to add messages, redirect messages to other sites, or intercept and corrupt voice messages.
