Prof. Osterweil, who joined Mason in fall 2018, is building a team of researchers to investigate ways to improve the security of core Internet protocols, including inter-domain routing, the super-highway of the Internet that carries all traffic­­, and the Domain Name System (DNS), the system that gives names to all Internet resources. He’s also working to extend those protections into other security mechanisms and tools throughout Internet systems.

This work could help prevent many common malicious attacks including data theft, problems with authentication and authorization, and distributed denial of service (DDoS) attacks—massive volumes of cyberattack traffic that routinely make headlines by knocking large websites offline, he says. “It will help secure email, the internet of things, mobile health, cyber-physical systems like those in cars.”
