CYBER RISKS TO 911: TELEPHONY DENIAL OF SERVICE
Telephony Denial of Service (TDoS) events can overwhelm call capacity and disrupt communications when a large volume of telephone calls overloads a communications network element.
Whether malicious (e.g., cyber attack) or accidental (e.g., malfunctioning equipment), TDoS events present a unique challenge for public safety stakeholders, specifically emergency communications centers (ECCs)/public safety answering points (PSAPs).
