Stop TDoS Attacks

Stop TDoS Attacks

Stop TDoS attacks (Telephony Denial of Service) from overwhelming your voice network or call center and preventing legitimate calls from getting through.

Stop TDos Attacks with the Call Secure™ Managed Service from SecureLogix

TDoS is a form of Denial of Service (DoS) that affects enterprise, government, and other business voice systems. It is a significant threat to voice systems and by far the most common form of voice-based DoS.

Who is At risk

TDoS can affect any government, enterprise, or small business, but most commonly impacts organizations with critical, public-facing contact centers. This includes 911, financial services, government, health care, and critical infrastructure. With TDoS, the objective is to make a significant number of calls and to keep those calls active for as long as possible, to overwhelm or at least “clog” all or a portion of the victim’s voice system. This can include trunk circuits, emergency phones, attendants/agents, an Interactive Voice Response (IVR) system, specific phone numbers, or some other choke point.

Types of TDoS Attacks

The TDoS threat is evolving. Attacks have evolved to the point where, as with any Distributed Denial of Service (DDoS) attack, automation is almost always used. Most automated call flooding attacks are fairly low volume and simple. The attackers do not need to generate many calls, because their victims are not entire organizations or sites. The attacker has the advantage, because it is easy to generate the attack, the target usually has a small number of critical lines, and the victim has very limited capability to deal with the attack.

Partnering with DHS to Defeat TDoS Attacks

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has partnered with our Vox Innovation Lab to solve complex TDoS issues and develop defense-based solutions to prevent these attacks. Our goal is to shift the advantage from TDoS attackers to network administrators by increasing the capability to detect and mitigate TDoS, by authenticating callers and detecting call spoofing.

Preventing and Mitigating TDoS Attacks

Our Call Secure™ managed service works to mitigate TDoS attacks (a.k.a. Call Flooding) by authenticating calls and helping to defeat fraudulent call spoofing. Speak to one of our voice security experts today about how to protect your voice network from TDoS and Call Flooding attacks.

TDoS Facts
  • Telephony denial of service can affect any government, enterprise, or small business, but most commonly impacts organizations with critical, public-facing contact centers.
  • As robocall and spoofing technology progresses, it becomes increasingly easy to generate large scale, high-volume TDoS attacks
  • Our Vox™ Innovation Lab has received $5 Million dollars in funding from DHS and DOD to research and fight TDoS and related threats
