As the SMPTE ST 2059 standards become more important for accurate synchronization and time labeling, it is equally important for users and system integrators to understand how time transmission can be influenced by the IEEE 1588 Precision Time Protocol (PTP) due to unintentional malfunctions or incorrectly configured devices as well as malicious attacks. Given the mission-critical nature of the broadcast infrastructure, secure time distribution quickly becomes a mandatory requirement. Although ST 2059-2 defines a PTP profile, it is not addressed how to secure all the parts that define the timing system. This is covered by a number of recommendations and best practices to ensure operational stability.
