Global Standards Collaboration (GSC)
GSC-15
Highlight of Current Activities (1)
ATIS’ Packet Technologies and Systems
Committee (PTSC)
 Completed:
•
•
•
•
UNI and NNI signalling security standards
UNI and NNI testing standards
NGN authentication requirements
Session Border Controller (SBC) requirements
 Security architecture is layered, both horizontally
and vertically, with border element functions
protecting trusted from untrusted domains
2
Highlight of Current Activities (2)
 PTSC continues to focus on security-related topics
that will ensure robust signalling and
communications standards and network
implementations that will provide adequate
protection and support for multimedia and
emergency services in the current cybersecurity
environment:
•
•
•
•
•
•
ETS Authentication
Data Border Function Requirements
Security Mechanisms
Location
Identity Management
Certificate Management
3
Highlight of Current Activities (3)
 PTSC’s focus is on specifying security
considerations for Layers 1 through 5 for UNIs,
NNIs, ANIs, and SNIs
• Generation of interface requirements will:
 Attempt to reduce number of available
interconnection options, without compromising the
desired flexibility in implementing the services,
thereby facilitating interoperability
 Facilitate interconnection negotiations
 Ensure adequate security will be provided
4
Highlight of Current Activities (4)
ATIS’ Network Performance, Reliability, and
QoS Committee (PRQC)
 Current/Future work:
• Currently working on Standard for Media Plane
Performance Security Impairments Standard for
Evolving VoIP/Multimedia Networks
 Document potential QoS degradations associated with security
mechanisms
 Identify potential security problems associated with QoS
mechanisms
• Extend work initiated in ATIS-0100014, Information &
Communications Security for NGN Converged Services
IP Networks and Infrastructure
 Published:
• ATIS-0100024.2009, User-Network Interface (UNI) Media Plane
Security Standard for Evolving VoIP/Multimedia Networks,
published.
• ATIS-0100014 (see above)
5
Highlight of Current Activities (5)
ATIS’ Telecom Management and Operations
Committee (TMOC)
 TMOC will continue to address
• Management aspects of security, especially
concerning NGN Carrier Interconnection
arrangements and VoIP Registry Database
• Management aspects of security, as driven by
the ATIS Board (e.g., TOPS Council or CIO
Council)
6
Strategic Direction
 ATIS continues to develop a suite of security
authentication and IdM standards that will facilitate
secure interconnection of:
• transport facilities
• signalling facilities
• services and applications
 Cloud computing may pose significant security
issues that will need to be addressed
7
Challenges
 SIP security solutions are tailored to be end
to end
 SIP/SIPPING/SIMPLE/etc. RFCs have well
written security sections that are not fully
implemented in vendor products
 Security solutions have an impact on delay
and performance
8
Next Steps/Actions
 ATIS will continue on its current path of
generating a complete suite of standards
that can be used to facilitate interconnection
negotiations and result in interconnection
scenarios that are secure
9
Proposed Resolution
 Continued support for GSC-14 Security
Related Resolutions:
• Resolution GSC-14/4 - Identity Management
• Resolution GSC-14/25 - Personally Identifiable
Information Protection
 Update Resolution GSC-14/11 - Cybersecurity
to reflect actions at WTDC10 (modified draft
Resolution provided as a GSC contribution)

Presentations
• Contributions GSC15-GTSC8-06, -07, -10, -11 and -14(-10, -11 and -14 contained
proposed updates to the existing Resolution)
Summary
• Cybersecurity continues to be one of the top priorities in the GSC members.
• Cloud Computing presents an added level of risk to data integrity, privacy and
availability. However, it also offers additional opportunities in these areas as well.
• Countries/regions are developing and sharing best practices to address the
cybersecurity challenges. This could be especially helpful to developing countries.
• The Cybex framework being developed in ITU-T SG 17 provides a model for
o structuring information
o identifying and discovering objects
o requesting and responding with information
o exchanging information over networks
o assured cybersecurity information exchanges
The specifications are especially relevant to Computer Incident Response Teams
(CIRTS), law enforcement and others that must exchange incident or related forensic
information
• Effective cooperation and collaboration across the many organizations, including
standards bodies, doing Cybersecurity work is essential.
Resolution
• Proposed revisions to Resolution GSC-14/11 on Cybersecurity.
