IDFP
IDFP, also known as Apple Filing Protocol over TCP, operates on port 549. It is primarily used for file sharing services on Apple devices, allowing users to transfer files seamlessly. This protocol ensures efficient and secure file sharing within Apple ecosystems.
What is IDFP
IDFP, or Apple Filing Protocol over TCP, is a network protocol that operates on port 549. It is designed to facilitate file sharing services, particularly within Apple environments. This protocol allows users to share files across different Apple devices, ensuring a smooth and efficient transfer process.
Historically, IDFP has been integral to Apple's networking capabilities, providing a reliable method for users to access and share files. The protocol supports various features such as file locking, permissions, and resource forks, which are essential for maintaining file integrity and security.
Apple Filing Protocol over TCP has evolved over the years to incorporate modern security measures and performance enhancements. It remains a critical component of Apple's file sharing services, enabling users to collaborate and share data effortlessly within the Apple ecosystem.
IDFP runs on TCP and UDP port 549 and is official IANA port.Security risk
If port 549 is open and the IDFP service is running, it could expose the network to unauthorized access and potential data breaches. Attackers could exploit vulnerabilities in the protocol to gain access to sensitive files and information. It is crucial to implement proper security measures, such as firewalls and access controls, to mitigate these risks.
In our UFW tutorial you can follow instructions how you can configure UFW to close port 549. Use StackChanges to monitor if the IDFP port is closed and stays closed. StackChanges will send an alert if port 549 is open again.
