Today, businesses use different communication mechanisms to modernise their digital communications. According to a Forbes Advisor Survey, 16% of workers spend 21 to 25 hours weekly on digital communication platforms. The growing need for advanced digital communication solutions has led businesses to embrace various technologies, including WebRTC (Web Real-Time Communication).
WebRTC is an open-source technology that enables real-time communication and data exchange between web browsers and devices through APIs. By enabling peer-to-peer interaction, WebRTC facilitates bidirectional video, audio, and text communication directly within web pages without native app downloads or plugin installations.

However, as WebRTC gains popularity, the capability of facilitating embedded audio or video communication within a web browser has given rise to security concerns surrounding this technology.
Therefore, Implementing robust security measures becomes crucial with the growing threat landscape.
This article explores WebRTC security, associated security concerns, and how WebRTC encryption can enhance communications.
WebRTC provides JavaScript APIs for developers to create P2P communication between web browsers and mobile apps. It enables real-time audio and video communication through web pages without plugins or custom software.
WebRTC security refers to the set of measures and protocols to ensure the privacy, confidentiality, and integrity of communications conducted through the WebRTC protocol. WebRTC communications leverage various security protocols, including end-to-end encryption (E2EE), to secure user connections.
In the case of unencrypted WebRTC communications, the entire session can become vulnerable, leading to compromised user identity and data theft. Therefore, it is essential to recognise the risks of unauthorised access and data breaches and the significance of encryption, authentication, and access control in WebRTC security.
Security considerations that may influence WebRTC security are:
While browser security doesn't directly secure the WebRTC connection, it contributes to securing the supporting connections and overall user experience. Moreover, DTLS, a standardised protocol embedded in WebRTC-supported browsers, encrypts information across web browsers, email, and VoIP platforms, ensuring secure communication channels.
Upgrade your operating system frequently to guarantee you have the most recent security fixes. Protect yourself against malware and illegal access by putting strong security measures in place, such as firewalls and antivirus software.
This leads to rapid discovery and correction of bugs and security flaws, ensuring security issues are swiftly addressed and feedback is provided to improve poorly developed WebRTC applications.
WebRTC leaks are a major security concern in using WebRTC to communicate. They occur when unintentional disclosure of IP addresses happens through web browsers, potentially revealing personally identifiable information such as IP addresses, DNS requests, and IP-based geolocations.
These leaks can compromise user privacy and sometimes expose identities even when anonymisation services are used. Alternatively, depending on your device and browser, implementing correct softwares such as Windows and Linux local security apps or a VPN service for Chromebooks might work to protect your devices against these leaks.
Therefore, discussing potential risks and weaknesses that could jeopardise your sensitive information is important. Let's discuss some of the WebRTC security issues you need to be aware of:
WebRTC encryption enables secure data transfer between browsers and apps using WebRTC-enabled connections. Since WebRTC sessions can't be secured using only standard security, incorporating encryption is necessary to tackle the security challenges WebRTC poses. Several data protection standards, such as the GDPR, also mandate the use of encryption for secure data transmission. To safeguard user privacy and prevent WebRTC leaks, using proxy servers ensures the anonymization of IP addresses and adds an extra layer of protection against data exposure.
It consists of three necessary WebRTC encryption specifications: Secure Real Time Protocol (SRTP), secure encryption key exchange, and secure WebRTC signalling. Every WebRTC session necessitates the implementation of these encryption protocols, which ensure the encryption of transmitted data, safeguard the encryption keys, and secure the connection to the web server.
These include the following:
WebRTC encryption makes up the protocol layer security of WebRTC-enabled connections.
Application-level security measures are necessary for WebRTC security to address the unique security requirements of individual applications, provide customised protection against risks, and enforce access control. This requires a comprehensive understanding of how security is managed in WebRTC and a commitment to developing applications that adhere to the same high standards.
Key considerations include securing the signalling channel. By safeguarding the signalling channel, the integrity and confidentiality of communication can be maintained, preventing unauthorised access or tampering.
Additionally, it is crucial to ensure that media servers, TURN servers, and application servers are protected against WebRTC vulnerabilities that may compromise their security. Regular security assessments, application of patches and updates, and adherence to industry best practices are essential to reduce the risk of threats.
WebRTC has become one of the most popular real-time communication protocols due to its high scalability and low latency. However, implementing security measures to protect sensitive information and ensure the integrity of communications is necessary.
