This work item will analyse and define the type of OAM functions for VNFs that can be generalized and be provided as a “generic function” supporting the provisioning, connectivity, configuration and monitoring of VNFs on a virtualized platform. The work item will also determine possible solutions to realize such generic OAM functions, e.g., by leveraging PaaS capabilities. The result report will include, if necessary, recommendations for requirements and architectural enhancements. The resulting deliverable will be informative.
This work item will study multi-tenancy related use cases for NFV to remove the gap between the existing IFA010 general functional requirements on multitenancy management and the missing requirement details regarding NFV elements consumed by different tenants. It will also take into consideration possible relation with Release 3 features like multi-domain NS provisioning, security orchestration. Key issues on multi-tenancy in NFV (e.g. tenant-dependent LCM, tenant dependent resource management, traffic separation, ..) will be identified and analyzed for concluding the recommendations.
The F5G Use Cases document ETSI GR F5G 002 has defined many use cases for F5G. To support these use cases, the network architecture will need to be simple, agile, optimized and intelligent. The present document defines the F5G E2E network architecture and related network node requirements, including Customer Premise Network (CPN), Access Network and Aggregation Network. F5G takes SDN/NFV into account for the network's control layer. The F5G architecture will explore new network features like a seamless connection between Optical Transport Network and Access Network, E2E full-stack slicing, etc. The F5G end-to-end management architecture is considered out of scope for the present document. The present document also specifies technical requirements for the network nodes and elements in the architecture. The focus will be on Telecommunication networks in particular.
This Recommendation proposes security guidelines for identity management (IdM) systems. The security guidelines provide how an IdM system should be deployed and operated for secure identity services in NGN (Next Generation Network) or cyberspace environment. The security guidelines focus on providing official advice how to employ various security mechanisms to protect a general IdM system and it also provides proper security procedures required when two IdM systems are interoperated.
Recommendation ITU-T X.1043 analyses security threats to and defines security requirements for software-defined networking (SDN) based service function chaining. The corresponding security countermeasures are also given. This Recommendation aims to help understanding of security risks encountered when using the SDN-based service function chaining and implementation of secured SDN-based service function chains.
Recommendation ITU-T X.1042 supports the protection of network resources using security services based on software-defined networking (SDN). This Recommendation first classifies the network resources for SDN-based security services: SDN application, SDN controller, SDN switch and security manager (SM). Recommendation ITU-T X.1042 then defines security services based on SDN.
Many organizations in developing countries as well as developed countries may have difficulties in implementing the high-level dimensions described in Recommendation ITU-T X.805. Recommendation ITU-T X.1039 is aimed at providing a set of security measures to implement the high-level dimensions. It also provides technical implementation guidance for security measures that can be used to improve organizations’ security response capabilities. A set of security measures described in this Recommendation could assist organizations in managing information security risks and implementing technical dimensions. The audience of this Recommendation includes, but is not limited to, those individuals responsible for implementing an organization's information security dimensions.
The Internet Protocol version 6 (IPv6) is intended to provide many built-in benefits such as large address space, and self-configuration capabilities. Because it is a new protocol that is likely to be massively adopted in the coming years and operates differently than the Internet Protocol version 4 (IPv4), both foreseeable and unforeseeable security issues will arise. Many new functions or requirements of IPv6, i.e., automatic configuration of interfaces, multicast addressing for specific services, the ability to assign multiple IPv6 addresses to a given interface, and for the use of the ICMPv6 protocol as the cornerstone of the IPv6 protocol machinery (dynamic neighbour discovery, ICMPv6 Router Advertisement (RA) messages that convey configuration information so that IPv6 terminal devices can automatically access to the IPv6 network, etc.) can be identified. Although somewhat equivalent capabilities exist in IPv4 and have been exposed to security threats for quite some time, IPv6 implementation and operation differs from IPv4, at the risk of raising specific security issues.
From that perspective, Recommendation ITU-T X.1037 provides a set of technical security guidelines for telecommunication organizations to deploy and operate IPv6 networks and services. The content of this Recommendation focuses on how to securely deploy network facilities for telecommunication organizations and how to ensure security operations for the IPv6 environment.
Supplement 12 to ITU-T X-series Recommendations, in particular to Recommendation ITU-T X.1240, describes the basic concept and characteristics of mobile messaging spam. It also introduces and analyses current technologies on countering mobile messaging spam. In addition, this supplement proposes a general implementation framework for countering mobile messaging spam. The relative activities in different organizations are introduced in Appendix I.
The purpose of this Recommendation is to analyse, structure and suggest a method for establishing an incident management organization within a telecommunication organization involved in the provision of international telecommunications, where the flow and structure of an incident are focused. The flow and the handling are useful in determining whether an event is to be classified as an event, an incident, a security incident or a crisis. The flow also covers the critical first decisions that have to be made. Computer crime follows in the wake of the heavily increased use of computers in international telecommunications. Over the last years, computer crime has literally exploded, as confirmed by several international and national surveys. In the majority of countries, there are no exact figures on the number of computer break-ins or security incidents, especially those related to international telecommunications.Most telecommunication organizations or companies do not have any specialized organization for handling Information and Communication Networks (ICN) security incidents (although they may have a general crisis team for handling crises of any type). When an ICN security incident occurs it is handled ad hoc, i.e., the person who detects an ICN security incident takes the responsibility to handle it as best as (s)he can. In some organizations the tendency is to forget and cover up ICN security incidents as they may affect production, availability and revenues.Often, when an ICN security incident is detected, the person who detects it does not know who to report it to. This may result in the system or network's administrator deploying a workaround or quick fix just to get rid of the problem. They do not have the delegated authority, time or expertise to correct the system so that the ICN security incident does not recur. These are the main reasons why it is better to have a trained unit or group that can handle security incidents in a prompt and correct manner. Furthermore, many of the issues may be in areas as diverse as media relations, legal, law enforcement, market share, or financial.When reporting or handling an incident, the use of different taxonomies leads to misunderstanding. This may, in turn, result in an ICN security incident getting neither the proper attention, nor the prompt handling, that is needed in order to stop, contain and prevent the incident from recurring. This may lead to serious consequences for the affected organization (victim).To be able to succeed in incident handling and incident reporting, it is necessary to have an understanding of how incidents are detected, handled and resolved. By establishing a general structure for incidents (i.e., physical, administrative or organizational, and logical incidents) it is possible to obtain a general picture of the structure and flow of an incident. A uniform terminology is the base for a common understanding of words and terms.
For quantum key distribution networks (QKDN), Recommendation ITU-T X.sec_QKDN_intrq specifies security requirements for integration of QKDN with various user networks (e.g., storage, cloud, sensor, content, etc.).
