Focus Group: Security Baseline for Network Operators (FG SBNO)
http://www.itu.int/ITU-T/studygroups/com17/sbno/index.html
Established October 2005 by SG 17 Objectives:
Define a security baseline against which network operators can assess their network and information security posture in terms of what security standards are available, which of these standards should be used to meet particular requirements, when they should be used, and how they should be applied
Describe a network operators readiness and ability to collaborate with other entities (operators, users and law enforcement authorities) to counteract information security threats
Provide meaningful criteria that can be used by network operators against which other network operators can be assessed, if required
Achieved Surveyed network operators by means of a questionnaire
Next step: Develop text to be proposed to SG 17 for progressing as an ITU-T
publication

Established December 2006 by SG 17 The objectives of the FG IdM are
to perform requirements analysis based on uses case scenarios, in order to identify generic IdM framework components, so that a standards gap analysis can be completed, in order to identify new standards work and the bodies (ITU and other SDOs) that
should perform the work

Security is everybody's business Collaboration with other SDOs is necessary Security needs to be designed in upfront Security must be an ongoing effort Systematically addressing vulnerabilities
(intrinsic properties of networks/systems) is key so that protection can be provided independent of what the threats (which are constantly changing and may be unknown) may be

ITU-T SG 17 Question 6Cyber Security
Motivation Objectives Scope Current area of focus Draft Recommendations under development
-
Q.6/17 Motivation
Network connectivity and ubiquitous access is central to todays IT systems
Wide spread access and loose coupling of interconnected IT systems is a primary source of widespread vulnerability
Threats such as: denial of service, theft of financial and personal data, network failures and disruption of voice and data telecommunications are on the rise
Network protocols in use today were developed in an environment of trust
Most new investments and development is dedicated to building new functionality and not on securing that functionality
An understanding of cybersecurity is needed in order to build a foundation of knowledge that can aid in securing the networks oftomorrow
-
Q.6/17 Objectives Perform actions in accordance with Lead Study Group (LSG)

-
Q.6/17 Draft Recommendations 1/5
1. Overview of Cybersecurity (X.1205, formerly X.cso) Provides a definition for Cybersecurity and a taxonomy of security threats
from an operator point of view. Cybersecurity vulnerabilities and threats are presented and discussed at various network layers.
Various Cybersecurity technologies that are available to remedy the threats include: Routers, Firewalls, Antivirus protection, Intrusion detection systems, Intrusion protection systems, Secure computing, Audit and Monitoring. Network protection principles such as defence in depth, access and identity management with application to Cybersecurityare discussed. Risk Management strategies and techniques are discussed including the value of training and education in protecting the network. A discussion of Cybersecurity Standards, Cybersecurityimplementation issues and certification are presented.
2. A vendor-neutral framework for automatic checking of the presence of vulnerabilities information update (X.vds)
Provides a framework of automatic notification on vulnerability information. The key point of the framework is that it is a vendor-neutral framework. Once users register their software, updates on the vulnerabilities and patches of the registered software will automatically be made available to the users. Upon notification, users can then apply.
-
Q.6/17 Draft Recommendations 2/5
3. Guidelines for Internet Service Providers and End-users for Addressing the Risk of Spyware and Deceptive Software (X.sds)
Provides guidelines for Internet Service Providers (ISP) and end-users for addressing the risks of spyware and deceptive software. The Recommendation promotes best practices around principles of clear notices, and users consents and controls for ISP web hosting services. The Recommendation also promotes best practices to end-users on the Internet to secure their computing devices and information against the risks of spyware and deceptive software.
4. Identity Management Framework (X.idmf) Develops an Identity Management Framework that leverages the use
case scenarios as it applies to Telecommunications and includes non-Telecom applications when (i.e., the orchestration of business processes that include supply change management, client resourcemanagement, enterprise resource management, location, presence, and other services). The framework enables service providers to provide entities with reliable, trusted and secure IdM services over distributed networks, through the appropriate use of authorization, authentication, access control mechanisms, and policy managementmechanisms.
-
Q.6/17 Draft Recommendations 3/5
5. Identity Management Requirements (X.idmr) Develops use case scenarios and requirements for the Identity
Management Framework Recommendation (X.idmf). The developed use cases cover Telecommunications and non-Telecom scenarios (i.e., the orchestration of business processes that include supply change management, client resource management, enterprise resource management, location, presence, and other services).
6. Identity Management Security (X.idms) Performs security analysis on the identity Management Framework as
developed in X.idmf. The Recommendation develops guidelines and best practice approach for ensuring that security is maintained when the Identity Management Framework is used as the vehicle for providing Telecommunications and non-Telecom IdM solutions.
-
Q.6/17 Draft Recommendations 4/5
7. Common Alerting Protocol (CAP v1.1), (X.1303, formerly X.cap) Specifies the common alerting protocol (CAP) which is a simple but
general format for exchanging all-hazard emergency alerts and public warnings over all kinds of networks. CAP allows a consistent warning message to be disseminated simultaneously over many different warning systems, thus increasing warning effectiveness while simplifying the warning task. CAP also facilitates the detection of emerging patterns in local warnings of various kinds, such as might indicate an undetected hazard or hostile act. And CAP provides atemplate for effective warning messages based on best practices identified in academic research and real-world experience. This Recommendation is technically equivalent and compatible with the OASIS Common Alerting Protocol, v.1.1 standard.
8. ASN.1 specification for the Common Alerting Protocol (CAP v1.1),(X.1303.1, formerly X.cap2)
The common alerting protocol (CAP) is specified in ITU-T Rec. X.1303, which is technically equivalent and compatible with the OASIS Common Alerting Protocol, V1.1 standard. This Recommendation provides an equivalent ASN.1 specification that permits a compact binary encoding and the use of ASN.1 as well as XSD tools for the generation and processing of CAP messages. This Recommendation enables existing systems, such as H.323 systems, to more readilyencode, transport and decode CAP messages.
-
Q.6/17 Draft Recommendations 5/5
9. Privacy guideline for RFID (X.rfpg) Recognizes that as RFID greatly facilitates the access and dispersion
of information pertaining specifically to the merchandise that individuals wear and/or carry; it creates an opportunity for the same information to be abused for tracking an individual's location or invading their privacy in a malfeasant manner. For this reason the Recommendation develops guidelines and best practices regarding RFID procedures that can be used by service providers to gain the benefits of RFID while attempting to protect the privacy rights of the general public within national policies.
10. Network Security Management Framework (X.nsmf) Defines the framework for security management to address how
telecom-operators can uniformly operate various kinds of security functions.
11. Guideline on preventing worm spreading in a data communication network (X.gopw)
Describes worm spreading patterns and scenarios in a data communication network. In addition, it specifies countermeasures to prevent from worm spreading. This Recommendation can be used as a guideline to network designers, network operator, and end users for preventing Worm spreading.
