About SMPTE Standards Development

The Society of movement Picture and tv Engineers (SMPTE) is definitely an worldwide-recognized Standards Development Organization (SDO), Incorporated and headquartered within the Condition of recent You are able to, USA. SMPTE has membership in additional than 64 countries on six continents.

SMPTE Engineering Documents, include Standards, Suggested Practices, Engineering Guidelines and Engineering Reports, the job a parent or gaurdian Standards Committee as well as several Technology Committees. Participation is available to with a genuine curiosity about the job. SMPTE cooperates carefully along with other standards development organizations, including ATSC, IEEE, IEC, ISO, ITU, and SCTE.

About SMPTE Study Groups (SG)

Study Groups (SG) are created with a SMPTE Technology Committee (TC) to look at a specific system or technology. The SG proceeds to research and focus the machine or technology and issues an Engineering Report (ER) towards the parent TC and Society Membership with the Motion imaging Journal and presentation at SMPTE Conferences. The SG frequently makes tips about Standards Development by SMPTE or any other industry Standards Development Organizations.

ST 2059/PTP SG Scope of labor

The SG on 2059/PTP Security was produced by SMPTE Engineering Leadership, SC, and TC chairs pursuant to some request in the Joint Task Pressure on Networked Media (JT-NM)[1]. The job was allotted to the TC on Network/Facilities Architecture (TC-32NF). The SG was forwarded to focus its analysis and focus on Security facets of ST 2059 Synchronization and Time Labeling Standards which derive from the Institut of Electrical and Electronic Engineers (IEEE) 1588 Precision Time Protocol (PTP).

Study Group scope of labor carefully follows concerns and questions articulated within the JT-NM request which described several regions of IP infrastructure security requiring improvement. SG activities are focused solely on security facets of ST 2059-1 and ST 2059-2 each of which derive from and compliant with IEEE 1588V2-2008 Precision Time Protocol (PTP).

ST 2059-1, Generation and Alignment of Interface Signals towards the SMPTE Epoch defines the SMPTE Epoch, the alignment real-time signals to that particular epoch, and calculation of SMPTE ST 12-one time Address values and SMPTE ST 309 date values from SMPTE Profile IEEE 1588-2008 PTP data. ST-2059-2, SMPTE Profile to be used of IEEE-1588 Precision Time Protocol in Professional Broadcast Applications specifies rules and parameters of the broadcast/media industry PTP profile. Together, these standards usually are meant to replace legacy synchronization signal distribution for example “black burst” and time code generation by IP-based PTP time distribution.

The SG regions of analysis and focus could be summarized the following:

Methods to harden PTP infrastructure from the assumption of PTP Grand Master with a rogue device
Methods to harden the network against PTP attacks generally (e.g., rogue management TLV messages or any other intentional attacks, altering PTP time)
Methods to improve time to recover when power is restored to some facility with a lot of PTP devices and whether this leads to a particular problem for PTP devices
Appropriate guidelines regarding the style of PTP systems to lessen the probability of a panic attack against critical PTP infrastructure
Appropriate test techniques to ensure devices implement recommendations in the various Coordination Group people
Means of discovering that attacks are occurring The Research Group should investigate issues surrounding PTP security inside a facility.

The SG is anticipated to provide a study through the finish of November 2019 identifying theoretical and observed security risks, and recommend a strategy or approaches, and/or minimization strategies that address threats that may disturb, disrupt, or else unfavorably impact greater-level system synchronization and timing characteristics.

Recommendations is going to be restricted towards the nature of, or proper protection facets of sync and timing network interface, ports, switch or routing hardware and protocols. (e.g., architectural characteristics, operational practice, device behavior, new specifications, new standards, etc.) and won’t be design specific solutions.

Current Work Activities from the Study Group

Current work products are highlighted below. Additional products might be uncovered as work progress unfolds. Their email list might be expanded just before completing work and delivery of the Report.

Define a typical vocabulary by means of a reference with acronyms, terms and definitions
Define and describe an architecture suitable for thought on threats and vulnerabilities over the SMPTE ST 2059/PTP attack surface where sync and time label reference signals are distributed and used within a facility
Identify threats to, and vulnerability of PTP infrastructure list these questions structured way
Define a appropriate threat modeling system and put it on their email list of PTP threats and perceived vulnerabilities

Future work can include:

Analysis and look at other industrial segment’s adoption from the PTP Standard by their growth and development of a business specific profile
Map PTP threats to reference signals and vulnerabilities of the model signal distribution network into aforementioned network architecture
Make tips about PTP network architecture and the way to safeguard it from a summary of defined attack vectors

Liaison Activities

The work isn’t being conducted in isolation. The Research Group arrived at to IEEE in which the PTP standard originated, and it is presently undergoing revision.

Demand Contributions

While operate in the research Group is proceeding, knowledge of securing PTP reference signals, identification of threats and vulnerabilities, hardening from the network and reference signals, network sturdiness, resilience, and reliability is open for contributions.

Please join your time and effort for those who have expertise and curiosity about Cybersecurity and also the To safeguard IP systems particularly when it comes to PTP infrastructure.
