VTC
Video Teleconferencing
Real-time video and audio meetings between remote participants over a network.
VTC delivers live audio and video between distributed participants and has become central to hybrid and remote work. Its security concerns include eavesdropping on unencrypted streams, uninvited participants joining poorly protected meetings, and recordings that leak sensitive discussion. Protections include encrypting media with SRTP, requiring authentication and waiting rooms, and patching the conferencing clients and appliances. On the exam, connect VTC to securing real-time media and the supporting SIP and RTP or SRTP protocols.
Looking VTC up is step one. Getting tested on it is step two.
