Abstract:
1. A computer-implemented method comprising: transmitting Session Initiation Protocol (SIP) request messages to a SIP proxy device, authenticating, during a first portion of the first time period and during a second portion of the first time period different than the first portion, the SIP request messages, wherein authenticating the SIP request messages includes determining which of the SIP request messages do not include spoofed source network addresses; blocking, during the first portion of the first time period but not during the second portion of the first time period, unauthenticated SIP request messages having a source address from which a SIP request message was already received; measuring, by a processor, a first performance associated with the SIP proxy device during the first portion of the first time period while authenticating and blocking; and measuring, by the processor, a second performance associated with the SIP proxy device during the second portion of the first time period while authenticating and not blocking.
