Fostering worldwide interoperability
Highlight of Current Activities (1)
ATIS’ Packet Technologies and
Systems Committee (PTSC)
Completed:
UNI and NNI signalling security standards
UNI and NNI testing standards
Encourages interfaces to support logging,
thereby facilitating the creation of incident
reports

2
Highlight of Current Activities (2)
PTSC continues to focus on securityrelated 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:
Authentication
Security Mechanisms
Location
Identity Management
Certificate Management
PTSC has also initiated an activity which
will define interconnection test suites

3
Highlight of Current Activities (3)
PTSC’s focus is on specifying security
considerations for Layers 1 through 5 for
UNIs, NNIs and SNIs
Generation of templates will:
Attempt to limit 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

Highlight of Current Activities (4)
ATIS’ Network Performance, Reliability, and
QoS Committee (PRQC)
Approved User-Network Interface (UNI) Media
Plane Security Standard for Evolving
VoIP/Multimedia Networks (ATIS-0100024.2009)
Currently working on Standard for Media Plane
Performance Security Impairments Standard for
Evolving VoIP/Multimedia Networks (Issue A035)
Document potential QoS degradations associated
with security mechanisms
Identify potential security problems associated with
QoS mechanisms
Current/Future work:
Development of Standards extending from the work
outlined in ATIS-0100014, Information &
Communications Security for NGN Converged
Services IP Networks and Infrastructure

Highlight of Current Activities (5)
ATIS’ Telecom Management and
Operations Committee (TMOC)
Recently completed work:
ATIS-0300074.2009, Guidelines and Requirements
for Security Management Systems
Includes an ATIS TMOC proforma requirements
statement for security aligning with ITU-T M.3410
TMOC will continue to address:
Management aspects of security, especially
concerning NGN Carrier Interconnection
arrangements and VoIP Registry Database
Provisioning

Strategic Direction
ATIS continues to develop a suite of security
standards that well facilitate secure
interconnection of:
transport facilities
signalling facilities
services
ATIS is not focusing on:
Security Mechanisms for Messaging Applications
Tracking
ATIS is looking to ITU-T to address the
messaging and tracking areas in the short term.
If ITU-T does not address this subject, ATIS may
reconsider work in this area.

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.
Availability of ITU-T Recommendations
which can be used to facilitate secure
transport and service interconnection.

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.
