Addressing security to enhance trust and confidence of users in networks, applications and services
 With global cyberspace, what are the security priorities for the ITU with its
government / private sector partnership?
 Need for top-down strategic direction to complement bottom-up,
contribution-driven process
 Balance between centralized and distributed efforts on security standards
 Legal and regulatory aspects of cybersecurity, spam, identity/privacy
 Address full cycle – vulnerabilities, threats and risk analysis; prevention;
detection; response and mitigation; forensics; learning
 Agree uniform definitions of cybersecurity terms and definitions
 Marketplace acceptance of Information Security Management System
(ISMS) standards (ISO/IEC 27000-series and ITU-T X.1051) – the
security equivalent to ISO 9000-series
 Effective cooperation and collaboration across the many bodies doing
cybersecurity work
 PSO help is needed in keeping security database up-to-date
 Informal security experts network – needs commitment
There is no “silver bullet” for cybersecurity

WSIS and Cybersecurity
Confidence and security are among
the main pillars of the information society
“Strengthening the trust framework, including information security
and network security, authentication, privacy and consumer protection, is a
prerequisite for the development of the Information Society and for building
confidence among users of ICTs. “
WSIS Geneva Declaration of Principles, Para 35
“We reaffirm the necessity to further promote, develop and implement in
cooperation with all stakeholders a global culture of cyber-security, as outlined
in UNGA Resolution 57/239 and other relevant regional frameworks.”
WSIS Tunis Agenda, Para 39

"The world must take action.
It must stand united.
This is not a problem any
one nation can solve alone"
Dr Óscar Arias Sánchez
Nobel Peace Laureate,
President of the Republic of Costa Rica,
Patron of the Global Cybersecurity Agenda.

Conclusions
Towards a global Cyberpeace…
The threats to global cybersecurity
demand a global framework!
The magnitude of this issue calls for a coordinated global
response to ensure that there are no safe havens for
cybercriminals.
ITU will act as a catalyst and facilitator for these partners to
share experience and best practice, so as to step up efforts for
a global response to cybercrime.
In this way, working together, we can create a cyberspace that
is somewhere safe for people to trade, learn and enjoy.

Information Security Management to be appropriately applied for
telecommunications organizations. Studies related on this issue can be a little
bit extended to cover the following items:
-
information security management guidelines (baseline)
information incident management guidelines
risk management and risk profiles guidelines
assets management guidelines
policy management guidelines
information security governance
etc.

SG 19 – Scope of security work
• Scope: IMT-2000 Family Member Networks
• Broad requirements for security are covered in the
following ITU-T Recommendations:
– Q.1701 “Framework for IMT-2000 networks”
– Q.1702 “Long-term vision of network aspects for
systems beyond IMT-2000”
– Q.1703 “Service and network capabilities framework
of network aspects for systems beyond IMT-2000”
139
SG 19 – Strategic directions
• Mainly derived from Q.1702 and Q.1703
– Q.1702 indicates the following objectives to provide
network security among heterogeneous interconnected networks:
• Comprehensive, cross-provider security infrastructure
support
• Well-defined and conducted routine system risk analysis
• Robust system intrusion monitoring and response system
to control damage
• Low overhead security protocols to accommodate
wireless bandwidth limitation
• Provide seamless security across heterogeneous access
technologies
140
SG 19 – Strategic directions
• Mainly derived from Q.1702 and Q.1703
– Rec. Q.1703 specifies that at least the following
security services should be provided:
• Integrity: contents as received are exactly as sent
• Confidentiality: user data is kept secret from
unintended listeners
• Non-repudiation: prevent denying a transmission was
initiated
• Mutual authentication: assurance that a participant is
who he claims to be
• Authorization: control user access to various network
resources
141
SG 19 – Security challenges
• To address security concerns arising due to:
– Migration from circuit switching to Packet switching (using
IP in wireless networks)
– Fixed Mobile Convergence (FMC): access & services
across heterogeneous networks (GSM, Wi-Fi, PSTN,
WiMAX, etc.) with the usage of IP
• To define a security framework applicable across
heterogeneous networks
142
SG 19 – Major security accomplishments
• Q.1707/Y.2804 (02/2008) “Generic Framework of Mobility
Management for NGNs”
– Designed to ensure that MM functions can interwork with the
relevant authentication and security protocols.
• Q.1742-series “IMT-2000 references to ANSI-41 evolved
core network with cdma2000 access”
– References to 3GPP security specifications

SG 19 – Major security accomplishments (2)
• Q.1762/Y.2802 “Fixed-mobile convergence general
requirements”
– Notes need for uniform authorization mechanism
– FMC may contain access-specific or -dependent parts but the
procedure for handling these is uniform
• Q.1763 “FMC service using legacy PSTN or ISDN as the
fixed access network for mobile network users”
– Authentication through a fixed network access provides for same
security mechanism as in the mobile network
– Refers to 3GPP TS 33.102 / ETSI TS 133.102 which address
UMTS 3G security and security architecture
144
SG 19 – Major security accomplishments (3)
• Working Draft Q.FMC-IMS “Fixed mobile convergence
with a common IMS session control domain” as of 14
May 2008
– Mobile access in mobile networks faces an increased level of
security threats compared to stationary access in fixed
networks
– Nomadic and wireless access in fixed networks utilize the
mobile world security framework (TS 33.203) for IMS access,
with the IMS Subscriber Identity Module (ISIM) as a key
component
– References IMS security (3GPP TR 33.978) and
authentication mechanisms (ETSI TS 187.003)
145
SG 19 – Security work for next study period
• F/19 : Convergence of existing and evolving IMT and
fixed networks
– FMC cannot be studied in isolation
– Has to take into account the ongoing work on NGN
scenarios, services, architecture, mobility, security and QoS,
and on mobile network technologies outside of ITU-T
– Study of specific FMC scenarios and solutions requires a solid
understanding of mobile network technologies and close
liaison with mobile network SDOs
146
SG 19 – Specific actions member
organizations of GSC should take
• Aim for globally consistent end-user security support
– Identify FMC security requirements for uniform authentication
and authorization mechanisms (i.e., authentication and
authorization combined)
– Network specific requirements for T-SPID
