DHS, SecureLogix develop TDoS attack defense

The U.S. Department of Homeland Security and vendor SecureLogix are making 'rapid progress' in developing a TDoS attack defense. The technology is expected in the coming months. The U.S. Department of Homeland Security has partnered with security firm SecureLogix to develop technology to defend against telephony denial-of-service attacks, which remain a significant threat to emergency call centers, banks, schools and hospitals. The DHS Science and Technology (S&T) Directorate said this week the office and SecureLogix were making "rapid progress" in developing defenses against call spoofing and robocalls -- two techniques used by criminals in launching telephony denial-of-service (TDoS) attacks to extort money. Ultimately, the S&T's goal is to "shift the advantage from TDoS attackers to network administrators." To that end, S&T and SecureLogix, based in San Antonio, are developing two TDoS attack defenses. First is a mechanism for identifying the voice recording used in call spoofing, followed by a means to separate legitimate emergency calls from robocalls.
