Communication protocol

Communication protocol definition

In cybersecurity, communication protocol refers to the system of various digital rules and permissions that allow two or more entities, like devices or software, to transmit and receive information to one another. It is necessary to understand how these protocols work to ensure secure data transfer across networks and network systems to prevent potential digital threats and recognize vulnerabilities.

Latest communication protocol applications in cybersecurity:

  • Post-quantum cryptography protocols: The growth of powerful quantum computers could pose a threat to cryptographic protocols. Due to that, new post-quantum cryptography methods are developed to ensure secure communication in a potential quantum-computing future.
  • IoT security protocols: In the advancement of IoT (internet of things), new security protocols like MQTT (Message Queuing Telemetry Transport) and CoAP (Constrained Application Protocol) are getting more popular because of their ability to securely transmit data between devices.
  • Secure real-time communication protocols: Due to the growing popularity of remote work and video conferencing, secure communication protocols are in demand. Protocols such as WebRTC (Web Real-Time Communication) are becoming critical. WebRTC and similar alternatives allow for peer-to-peer communication in web browsers and various mobile applications, emphasizing encryption and overall security.
