dtls

DTLS (Datagram Transport Layer Security) is a protocol that provides privacy for datagram-based communications, commonly used in WebRTC applications like Microsoft Teams and Zoom. On WindowsForum.com, discussions cover DTLS in two contexts: a security concern known as "Ghost Calls," where attackers can hijack TURN infrastructure to tunnel command-and-control traffic through DTLS-encrypted media streams, bypassing enterprise defenses; and a historical update that added DTLS support to Windows 7 SP1 and Windows Server 2008 R2 SP1 to reduce protocol overhead on slow network connections. These threads highlight DTLS's role in both enabling real-time communications and introducing potential security risks.
