Spoofing Mitigation Information Document Now Available
Recent regulatory activity in North America has had a strong emphasis on combatting nuisance calls, including robocalls and calls with illegitimate caller identity spoofing. The spoofing of critical information, like caller identity, associated with emergency calls and callback calls will negatively impact public-safety communications and emergency response.
The NENA Spoofing Mitigation Information Document addresses operational as well as technical impacts associated with applying information spoofing mitigation techniques to 9?1?1 calls and emergency callbacks in an all-IP environment. In addition, this document provides background on regulatory drivers behind the specification of spoofing mitigation activities, describes use cases in which the application of spoofing mitigation techniques may assist Public Safety agencies in detecting and mitigating Telephony Denial of Service (TDoS) and swatting attacks, and identifies open issues related to information spoofing that still need to be addressed.
