Internet Architecture Board. The Internet Architecture Board (IAB) is a committee of the Internet Engineering Task Force (IETF) and an advisory body of the Internet Society (ISOC). Its responsibilities include architectural oversight of IETF activities, Internet Standards Process oversight and appeal, and the appointment of the Request for Comments (RFC) Editor. The IAB is also responsible for the management of the IETF protocol parameter registries.

History 
The body which eventually became the IAB was originally the Internet Configuration Control Board (ICCB). It was created by Vint Cerf in 1979 while he was working at the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense. In 1983, the ICCB was reorganized by Barry Leiner, Cerf's successor at DARPA, around a series of task forces considering different technical aspects of internetting. The re-organized group was named the Internet Activities Board (IAB).

The IAB set for itself seven principal foci for the period of 1989 to 1990. These were namely:

Operational Stability
User Services
OSI Coexistence
Testbed Facilities
Security
Getting Big
Getting Fast

It finally became the Internet Architecture Board, under ISOC, in January 1992, as part of the Internet's transition from a U.S.-government entity to an international, public entity.

Responsibilities 
The IAB is responsible for:

Providing architectural oversight of Internet protocols and procedures
Liaising with other organizations on behalf of the Internet Engineering Task Force (IETF)
Reviewing appeals of the Internet standards process
Managing Internet standards documents (the RFC series) and protocol parameter value assignment
Confirming the Chair of the IETF and the IETF Area Directors
Selecting the Internet Research Task Force (IRTF) Chair
Acting as a source of advice and guidance to the Internet Society.

In its work, the IAB strives to:

Ensure that the Internet is a trusted medium of communication that provides a solid technical foundation for privacy and security, especially in light of pervasive surveillance,
Establish the technical direction for an Internet that will enable billions more people to connect, support the vision for an Internet of things, and allow mobile networks to flourish, while keeping the core capabilities that have been a foundation of the Internet's success, and
Promote the technical evolution of an open Internet without special controls, especially those that hinder trust in the network.

Responsibilities
The IAB's current responsibilities include:

Architectural Oversight: The IAB provides oversight of, and occasional commentary on, aspects of the architecture for the network protocols and procedures used by the Internet.
Standards Process Oversight and Appeal: The IAB provides oversight of the process used to create Internet Standards. The IAB serves as an appeal board for complaints of improper execution of the standards process, through acting as an appeal body in respect of an Internet Engineering Steering Group (IESG) standards decision.
Request for Comments series: The IAB is responsible for editorial management and publication of the Request for Comments (RFC) document series.
Internet Assigned Numbers Authority: In conjunction with the Internet Corporation for Assigned Names and Numbers (ICANN), the IAB is responsible for the administration of the assignment of IETF protocol parameter values by the Internet Assigned Numbers Authority (IANA).
External Liaison: The IAB acts as representative of the interests of the IETF in liaison relationships with other organizations concerned with standards and other technical and organizational issues relevant to the worldwide Internet.
Advice to the Internet Society: The IAB acts as a source of advice and guidance to the board of trustees and Officers of ISOC concerning technical, architectural, procedural, and (where appropriate) policy matters pertaining to the Internet and its enabling technologies.
Internet Engineering Steering Group Confirmation: The IAB confirms the IETF Chair and IESG Area Directors, from nominations provided by the IETF Nominating Committee.
Internet Research Task Force Chair: The IAB selects a chair of the IRTF for a renewable two-year term.

RFC1087 – Ethics and the Internet and a rise to modernity
The IAB takes a formal stance on what constitutes proper use of the Internet in their 1989 memo, RFC 1087: “Ethics and the Internet.” They introduce their contemporary version of the Internet, which at the time was in its nascent stages, serving primarily as a tool for communication of research in the scientific community, and identify the use of this internet as a “privilege.”

The IAB then proclaims as unethical any activity which:
 seeks to gain unauthorized access to the resources of the Internet,
 disrupts the intended use of the Internet,
 wastes resources (people, capacity, computer) through such actions,
 destroys the integrity of computer-based information
 compromises the privacy of users.
 
This memo was written at a time during which the Internet existed in the general research milieu, but since that time the Internet has evolved greatly and expanded its user base. The IAB has accordingly taken new stances on ethical and secure Internet use, such as in RFC 8890, where the IAB identifies protecting end users as the first priority in their maintenance of the Internet.

As such, though their core principles are the same, the IAB's priority for protection has shifted from the technical and scientific community to the community of day-to-day users. In another memo RFC7624, the IAB takes a firm stance against pervasive mass surveillance through the use of the Internet on the part of national intelligence agencies, saying that it is necessary that the Internet technical community, including itself, “address the vulnerabilities exploited [by mass surveillance campaigns]...to ensure that the Internet can be trusted by [its] users.”

RFC 2850 - Charter of the Internet Architecture Board
RFC 2850 establishes the structure and purpose of the IAB. The RFC specifies the following:
 IAB membership: the IAB has 13 members, 1 being the chair of the Internet Engineering Task Force (IETF). These members are appointed to 2-year terms.
 The Role of the IAB: The IAB serves to provide Architectural Oversight for Internet procedures, and to provide oversight in the process of creating Internet standards, including appeals. Furthermore, the IAB acts as a liaison to the Internet Society (ISOC) to advise regarding architectural and technical issues.
 IAB Organization: The 13 members of the IAB choose 1 member to serve as the chair of the IAB for a 1-year term. There is no limit to the number of terms that the chair can serve. The executive director of the IAB is chosen by the chair. The IAB also has the power to designate the chair of the Internet Research Task Force (IRTF) for a 2-year term.
 Decision-making: in most situations, the IAB aims to come to unanimous decisions on matters. When this is not possible, the IAB must come to a consensus of at least 7 members before taking action.
 Openness and confidentiality: The IAB makes all meetings open to the public by making it available online, and also publishes RFCs regularly to make its conclusions generally available. In some situations, however, confidential information is excluded for privacy reasons.

RFC 2026 - The Internet Standards Process
The Internet Standards process is an activity of the Internet Society that is organized and managed on behalf of the Internet community by the Internet Architecture Board (IAB) and the Internet Engineering Steering Group (IESG). The Internet Standards Process is concerned with all protocols, procedures, and conventions that are used in or by the Internet. The process of creating an Internet Standard is straightforward: a specification undergoes a period of development and several iterations of review by the Internet community and revision based upon experience, is adopted as a Standard by the appropriate body (either the IAB or the IESG), and is published. Each distinct version of an Internet standards-related specification is published as part of the "Request for Comments" (RFC) document series. This archival series is the official publication channel for Internet standards documents and other publications of the IESG, IAB, and Internet community. The complete Internet Standards Process is itself specified by an RFC, namely RFC 2026.

RFC 8980 - Workshop on Design Expectations vs. Deployment Reality in Protocol Development 
The RFC 8980 workshop was held in February 2021, where the IAB discussed several topics around security protocols, including:

Email standards, which presumed many providers running in a largely uncoordinated fashion but have seen both significant market consolidation and a need for coordination to defend against spam and other attacks. The coordination and centralized defense mechanisms scale better for large entities; these have fueled additional consolidation.
The Domain Name System (DNS), which presumed deep hierarchies but has often been deployed in large, flat zones, leading to the nameservers for those zones becoming critical infrastructure. Future developments in DNS may see concentration through the use of globally available common resolver services, which evolve rapidly and can offer better security. Paradoxically, the concentration of these queries into a few services creates new security and privacy concerns.
The Web, which is built on a fundamentally decentralized design but is now often delivered with the aid of Content Delivery Networks (CDNs). Their services provide scaling, distribution, and prevention of denial of service in ways that new entrants and smaller systems operators would find difficult to replicate. While truly small services and truly large services may each operate using only their own infrastructure, many others are left with the only practical choice being the use of a globally available commercial service.

The workshop resulted in the following recommendations by the IAB:
 Develop and document a modern threat model.
 Continue discussion of consolidation/centralization issues.
 Document architectural principles, e.g., (re)application of the end-to-end principle.
