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.1602 analyses the maturity levels of software as a service (SaaS) application and proposes security requirements to provide a consistent and secure service execution environment for SaaS applications. These proposed requirements originate from cloud service providers (CSP) and cloud service partners (CSN) as they need a SaaS application environment to meet their demands on security. The requirements are general and independent of any service or scenario specific model (e.g. web services, or representational state transfer (REST)), assumptions or solutions.
Recommendation ITU-T X.1364 analyses potential deployment schemes and typical application scenarios for narrowband Internet of things (NB-IoT). It specifies security threats and requirements specific to the NB-IoT deployments and establishes a security framework for the operator to safeguard new NB-IoT technology applications. Current developments in telecommunication technology in the mobile communication domain, are leading to changes in communication patterns from person-to-person to person-to-thing and thing-to-thing, making inevitable the evolution to the Internet of things. Compared to short distance communication technologies such as Bluetooth, ZigBee and others, cellular mobile networks characterized by wide coverage, mobility and extensive connections that bring richer application scenarios will become the main interconnection technology of IoT. NB-IoT is based on cellular mobile network technology, using a bandwidth of approximately only 180 KHz. It may be deployed on global system for mobile communication (GSM) networks, universal mobile telecommunications system (UMTS) networks or long-term evolution (LTE) networks directly to reduce costs and achieve a smooth upgrade. Based on its low power dissipation, wide coverage, low cost and high capacity, NB-IoT is expected to be massively adopted by operators with wide application in multiple vertical industries. As a new technology, NB-IoT has its own characteristics that may bring new security issues. In order to ensure security of NB-IoT deployments and applications, security threats and relevant security requirements specific to NB-IoT need to be analysed and an overall security framework for NB-IoT needs to be established.
Biometric technology in mobile devices is frequently used in various areas that require a high level of reliability, such as a smart car, e-banking, e-payment, telemedicine and e-healthcare services. In particular, it is necessary to implement countermeasures, which can pre-emptively cope with fake physiological biometrics to ensure mobile telebiometric data security, to presentation attacks. Recommendation ITU-T X.1094 specifies new secure and strong telebiometric authentication methods using biosignals.
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.
Recommendation ITU-T X.1040 analyses the main features and typical threats faced by e‑commerce service ecosystems, and provides a security reference architecture for lifecycle management of e-commerce business data.
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.
