What is MACROMEDIA-FCS

MACROMEDIA-FCS, now known as Adobe Flash Media Server, is a robust platform for streaming audio, video, and data over the internet. Initially developed by Macromedia and later acquired by Adobe Systems, this service has been instrumental in delivering rich media content to users worldwide. It supports both live and on-demand streaming, making it a versatile tool for broadcasters, educators, and content creators.

The service operates over port 1935, which is specifically designated for this purpose. Adobe Flash Media Server uses the Real-Time Messaging Protocol (RTMP) to facilitate low-latency streaming, ensuring a smooth and uninterrupted viewing experience. This has made it a popular choice for live events, webinars, and other real-time applications.

Over the years, Adobe Flash Media Server has evolved to include advanced features such as adaptive bitrate streaming, digital rights management (DRM), and integration with various content delivery networks (CDNs). Despite the decline in Flash usage, the underlying technology continues to influence modern streaming protocols and platforms.

MACROMEDIA-FCS runs on TCP and UDP port 1935 and is official IANA port.

Security risk

If port 1935 is open and the service is running, it could be a target for unauthorized access and streaming hijacking. Attackers could exploit vulnerabilities in the service to intercept or disrupt media streams. Ensuring the service is properly secured and up-to-date is crucial to mitigate these risks.

In our UFW tutorial you can follow instructions how you can configure UFW to close port 1935. Use StackChanges to monitor if the MACROMEDIA-FCS port is closed and stays closed. StackChanges will send an alert if port 1935 is open again.
