2

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

3

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

4

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

5

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)

6

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)

7

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

8

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

9

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

10

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)
