CYBERSECURITY-RELATED STANDARDS ACTIVITY IN THE TELECOMMUNICATIONS INDUSTRY ASSOCIATION Eric Barnhart, Division Chief Georgia Tech Research Institute
TIA Cybersecurity Background • TIA focus on Critical Infrastructure Protection and Homeland Security includes efforts in Network Security • TIA TR-51 (Smart Utility Networks) views TR-50 (Smart Device Communications) as logical group to address security in parallel with deference to ITU-T SG17 (cybersecurity) from ITU Focus Group SMART • TIA urges caution in establishing any USA government mandated security certification programs (TIA comments in US FCC PS Docket No. 10-93) • more data is needed with rapidly evolving needs • certification programs may not be most effective protection • Government mandated certification program could stifle needed flexibility
Highlight of Current Activities • TIA TR-50 (Smart Device Communications) established Security Ad Hoc Group in February, 2011 • Supports TR-50 and its other subcommittees to contribute requirements, architecture, protocols, etc. related to the topic of security in Smart Device Communications. • Reviews/approves all ballots by TR-50 and its subcommittees to ensure that any architectures, protocols, or specifications meet the requirements set by the SDC Security Ad Hoc Group for secure solutions. • Architecture, protocols, or specifications should support options that can be exported without restriction from countries for which TIA serves as a regional Standards Development Organization (SDO).
Highlight of Current Activities • TIA TR-50 Smart Device Communications Security Ad Hoc Group Activity includes development of: • Data-in-Transit Use Cases to support progress toward Machine-to-Machine (M2M) Multilayer Distributed Security Architecture (MMDSA)
Highlight of Current Activities • TIA TR-50 Smart Device Communications Security Ad Hoc Group Activity: • Developing M2M Threat Analysis Overview to drive architecture development in tandem with Use Cases • Includes Operating System and Applications layer considerations; User Data considerations; and Network considerations. • Methodology includes measures of threat Likelihood and Impact. Product of these factors produces Risk Assessment Level:
TIA Strategic Direction • TIA supports cyber security objectives and study items of ITU-T Study Group 17 as captured in Question 4/17- Cybersecurity • TIA 2011 Goals and Positions include: • Government and industry must partner to increase the number of dialogues between domestic and foreign experts to discuss international best practices • Support cybersecurity policies that keep markets open and minimize barriers to trade
Challenges • With M2M Cybersecurity in TR-50 (Smart Device Communications) as current TIA cybersecurity focal point, extend focus as appropriate to address needs: • TR-30 Multimedia Access, Protocols and Interfaces • TR-41 User Premises Telecommunications Systems • TR-45 Mobile and Personal Communications Systems Standards • TR-47 Terrestrial Mobile Multimedia Multicast • TR-48 Vehicular Telematics • TR-49 Healthcare ICT
Challenges • Embracing user community (including verticals) is vital • User needs are particularly important to understand with regard to risks and security demands – examples include energy management and healthcare ICT • Export control and harmonization issues demand attention
Next Steps / Actions • In TIA TR-50 Smart Device Communications Security Ad Hoc Group: • Continue focus on Data In Transit • Multilayer Security • Security Zone Definitions • Continue focus on Data At Rest • Trusted Environments • Continue focus on Threat Analysis • Risk Analysis • Financial Impact • Attack Trees • Examine Test Bed needs to investigate cybersecurity issues
Supplementary Comments on M2M SDC Threat Assessment In order to quantify vulnerability, we assign numeric values to multiple factors. Vulnerability is calculated as the product of likelihood and impact (after NIST, OWASP,SANS Institute, and other similar approaches for IT risk management). • Likelihood factor ranges from 1 through 4 with the following levels defned: • 1 = “Low Likelihood” being the least likely due to little or no motivation, opportunity and/or capability • 2 = “Moderate Likelihood” being of moderate likelihood, with average motivation, opportunity and/or capability • 3 = “Substantial Likelihood” being substantial likelihood, with high motivation, opportunity and/or capability • 4 = “Severe Likelihood” being the most likely as an agent with high motivation, opportunity and capability.
Supplementary Comments on M2M SDC Threat Assessment Criteria assigning likelihood levels include assessing the attacker, motivation, opportunity, and capability:
Supplementary Comments on M2M SDC Threat Assessment Impact characterizes the implications/seriousness of a successful attack, with the following levels: • 1 = minor impact or no effect to the stakeholder • 2 = serious impact, including impacting revenue streams, processes, support systems • 3 = wide spread impact, causing irreparable damage to key systems and processes • 4 = severe impact causing damage to systems and processes that support infrastructure requirements.
