Information technology — W3C Web Content Accessibility Guidelines (WCAG) 2.2

Information technology — W3C Web Content Accessibility Guidelines (WCAG) 2.2

Web Content Accessibility Guidelines (WCAG) 2.2 defines how to make Web content more accessible to people with disabilities. Accessibility involves a wide range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities. Although these guidelines cover a wide range of issues, they are not able to address the needs of people with all types, degrees, and combinations of disability. These guidelines also make Web content more usable by older individuals with changing abilities due to aging and often improve usability for users in general. WCAG 2.2 success criteria are written as testable statements that are not technology-specific. Guidance about satisfying the success criteria in specific technologies, as well as general information about interpreting the success criteria, is provided in separate documents. The WCAG 2.2 standard, technical and educational material supporting implementation of WCAG 2.2, and translations of WCAG 2.2 are available from the Web Content Accessibility Guidelines (WCAG) Overview.

Information technology — Software Carbon Intensity (SCI) specification

This document describes a methodology for calculating the rate of carbon emissions for a software system; that is, its SCI score. The purpose of this score is to increase awareness and transparency of an application's sustainability credentials. The score will help software practitioners make better, evidence-based decisions during system design, development, and deployment, that will ultimately minimize carbon emissions. A reliable, consistent, fair and comparable measure allows targets to be defined during development and progress to be tracked.

Information technology — Object Management Group Unified Profile for DoDAF and MODAF (UPDM), 2.1.1

This International Standard provides a specification language, UPDM, that is readily understandable not only by the community of architects of information technology systems but also by a wide range of end users including executives and enterprise management that sponsor such systems, program managers that oversee their development, developers of supporting hardware and software (design, implementation, and testing), subject matter experts, and end users. UPDM bridges the gap from setting of requirements to high level system design and to visualization for practitioners. While designed in the context of military organizations and their procurement processes, UPDM can also be applied in entirely civilian industrial and service organization contexts. UPDM 2.1.1 supports the capability to: ? model architectures for a broad range of complex systems, which may include hardware, software, data, personnel, and facility elements; ? model consistent architectures for system-of-systems down to lower levels of design and implementation; ? model service oriented architectures; ? support the analysis, specification, design, and verification of complex systems; and ? improve the ability to exchange architecture information among related tools that are UML based and tools that are based on other standards. The profile provides the modeling of operational capabilities, services, system activities, nodes, system functions, ports, protocols, interfaces, performance, and physical properties and units of measure. In addition, the profile enables the modeling of related architecture concepts such as DoD's doctrine, organization, training material, leadership & education, personnel, and facilities (DOTMLPF) and the equivalent UK Ministry of Defence Lines of Development (DLOD) elements. UPDM 2.1.1, as illustrated in Figure 1.1, addresses DoDAF and MODAF Viewpoints as well as enabling extensions to new architecture perspectives (e.g., Services views, Custom views, Logistics views cost views, etc.). MODAF terminology has been used for simplicity.

Information Technology — BIOS Protection Guidelines

ISO 19678:2015 provides requirements and guidelines for preventing the unauthorized modification of Basic Input/Output System (BIOS) firmware on PC client systems. Unauthorized modification of BIOS firmware by malicious software constitutes a significant threat because of the BIOS's unique and privileged position within the PC architecture. A malicious BIOS modification could be part of a sophisticated, targeted attack on an organization ?either a permanent denial of service (if the BIOS is corrupted) or a persistent malware presence (if the BIOS is implanted with malware). As used in this publication, the term BIOS refers to conventional BIOS, Extensible Firmware Interface (EFI) BIOS, and Unified Extensible Firmware Interface (UEFI) BIOS. This International Standard applies to system BIOS firmware (e.g., conventional BIOS or UEFI BIOS) stored in the system flash memory of computer systems, including portions that may be formatted as Option ROMs. However, it does not apply to Option ROMs, UEFI drivers, and firmware stored elsewhere in a computer system. Subclause 7.2 provides platform vendors with requirements for a secure BIOS update process. Additionally, subclause 7.3 provides guidelines for managing the BIOS in an operational environment. While this International Standard focuses on current and future x86 and x64 client platforms, the controls and procedures are independent of any particular system design.

Information technology — W3C Web Content Accessibility Guidelines (WCAG) 2.0

ISO/IEC 40500:2012 [Web Content Accessibility Guidelines (WCAG) 2.0] covers a wide range of recommendations for making Web content more accessible. Following these guidelines will make content accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photo-sensitivity and combinations of these. Following these guidelines will also often make your Web content more usable to users in general. WCAG 2.0 success criteria are written as testable statements that are not technology-specific. Guidance about satisfying the success criteria in specific technologies, as well as general information about interpreting the success criteria, is provided in separate documents. An overview of WCAG 2.0, the WCAG 2.0 standard, technical and education material supporting implementation of WCAG 2.0, and information on translating WCAG 2.0, are freely available from Web Content Accessibility Guidelines (WCAG) Overview.

Information technology — SOA Governance Framework

ISO/IEC 17998:2012 describes a framework that provides context and definitions to enable organizations to understand and deploy service-oriented architecture (SOA) governance. ISO/IEC 17998:2012 defines: SOA Governance, including its relationship between Business, IT, and EA governance; this assists organizations in understanding the impact that the introduction of SOA into an organization has on governance; an SOA Governance Reference Model (SGRM) and its constituent parts, which assists organizations in specifying their appropriate governance regimes; and capturing best practice as a basis for a common approach; the SOA Governance Vitality Method (SGVM) which assists organizations in customizing the SGRM and realizing their SOA Governance Regimen. ISO/IEC 17998:2012 is not intended to be used as provided; it is intended to be customized to create appropriate SOA governance for the organization. Many of the lists are non-normative and exemplary and intended to be filtered and as input to the customization process. ISO/IEC 17998:2012 does not include an explanation of the fundamentals and value of SOA, which is important for being able to understand and apply SOA governance. It lists some of the many other specifications and books that are available on SOA basics.

Information technology — Object Management Group — Common Object Request Broker Architecture (CORBA) — Part 2: Interoperability

ISO/IEC 19500-2:2012 specifies a comprehensive, flexible approach to supporting networks of objects that are distributed across and managed by multiple, heterogeneous CORBA-compliant Object Request Brokers (ORBs). The approach to inter-ORB operation is universal, because elements can be combined in many ways to satisfy a very broad range of needs. ISO/IEC 19500-2:2012 specifies ORB interoperability architecture Inter-ORB bridge support General Inter-ORB Protocol (GIOP) for object request broker (ORB) interoperability. GIOP can be mapped onto any connection-oriented transport protocol that meets a minimal set of assumptions defined by this International Standard Internet Inter-ORB Protocol (IIOP), a specific mapping of the GIOP which runs directly over connections that use the Internet Protocol and the Transmission Control Protocol (TCP/IP connections) CORBA Security Attribute Service (SAS) protocol and its use within the CSIv2 architecture to address the requirements of CORBA security for interoperable authentication, delegation, and privileges ISO/IEC 19500-2:2012 provides a widely implemented and used particularization of ITU-T Rec. X.931 | ISO/IEC 14752. It supports interoperability and location transparency in ODP systems.

Information technology — Object Management Group — Common Object Request Broker Architecture (CORBA) — Part 1: Interfaces

ISO/IEC 19500-1:2012 specifies the CORBA Object Model and uses concepts from that model to define the operation of the Object Request Broker (ORB). The ORB is the basic mechanism by which objects transparently make requests to, and receive responses from, each other on the same machine or across a network. A client need not be aware of the mechanisms used to communicate with or activate an object, how the object is implemented, or where the object is located.
