The Growing Threat to PSAPs from Telephony Denial of Service (TDoS) Attacks

Wednesday, July 3, 2013

In March 2012 the Department of Homeland Security (DHS) National Coordinating Center for Communications issued an alert that several Public Safety Answering Points (PSAPs) had experienced a new and somewhat unexpected problem: Telephone Denial of Service (TDoS) attacks that threatened the PSAP’s ability to communicate with inbound callers and first responders alike.

In the ongoing discussion of how public safety can mitigate TDoS attacks, this article will focus on the hardening of existing 9-1-1 technologies and how Next Generation 9-1-1 (NG9-1-1) will substantially increase the capacity of PSAPs to handle large call volumes, whether resulting from TDoS attacks or from concurrent legitimate calls. And finally, it will address how FirstNet, the new nationwide public safety network, will play a critical role in securing public safety communications and 9-1-1 calls.
