  • The Internet and Isi: Four Decades of Innovation
    THE INTERNET AND ISI: FOUR DECADES OF INNOVATION ROD BECKSTROM President and Chief Executive Officer Internet Corporation for Assigned Names and Numbers (ICANN) 40th Anniversary of USC Information Sciences Institute 26 April 2012 As prepared for delivery It’s an honor to be here today to mark the 40th anniversary of the University of Southern California’s Information Sciences Institute. Thank you to Herb Schorr for inviting me to speak with you today and participate in the day’s events. When he steps down he will leave some very large shoes to fill. When I received Herb’s invitation, I seized upon it as an opportunity to come before you to express the sincere gratitude that my colleagues and I feel for the work and support of ISI. When I think of ICANN and its development, and all we have accomplished, I never forget that we stand upon the shoulders of giants, many of whom contributed to my remarks today. In fact, I owe a special debt of gratitude to Bob Kahn, who has been a mentor to me. I am honored that he took the time to walk through a number of details in the history I have been asked to relate. The organizers asked me to speak about the history of ISI and ICANN. They also invited me to talk a bit about the future of the Internet. In my role as President and CEO of ICANN, I have many speaking engagements that are forward looking. They are opportunities to talk about ICANN’s work and how it will usher in the next phase in the history of the global, unified Internet that many of you have helped to create.

  • Digitalization of Public Services in Moldova in the Covid-19 Era
    UNITED NATIONS DEVELOPMENT PROGRAMME DIGITALIZATION OF PUBLIC SERVICES IN MOLDOVA IN THE COVID-19 ERA The Impact of COVID-19 It is now six months since the COVID-19 pandemic engulfed our world. It has now become clear that our lives are unlikely to return quickly, if ever, to our previous normality. The COVID-19 pandemic has exposed flaws and limitations in our existing systems and norms. Everybody has either witnessed or experienced large-scale lockdowns. And although the world is re-opening now, COVID-19 is still spreading around the world. Our societies will have to adapt to a “new normal” in practically everything we do. Public services are vital for people’s livelihoods. Everyday people need public services to help them access services, register for retraining programmes or receive social benefits. In this “new normal” the government should make long-term improvements to public services, with a focus on filling the gaps in infrastructure and designing personalized public services. Virtual communication and connectedness will not end with the end of the lockdown. Face-to-face communication will still be important in service provision. However, the government should gradually create the conditions when people will not feel a radical difference between virtual (digital) and physical delivery of public services. To achieve this, it is crucial for the Government to bring the spirit of human interaction and connectedness to digital public services. How do we combine all of this and make public services efficient, personalized, trustworthy, human and most importantly safe in the post-COVID era in Moldova? We attempt to address these questions in this brief.

Systad, Jan Ove Bustnes, Signe Christensen-Dalsgaard, Sébastien Descamps, Kjell-Einar Erikstad, Arne Follestad, Sveinn Are Hanssen, Magdalene Langset, Svein-Håkon Lorentsen, Erlend Lorentzen, Hallvard Strøm, © SEAPOP 2019 SEAPOP Short Report 1-2019 Key-site monitoring in Norway 2018, including Svalbard and Jan Mayen Breeding success The 2018 breeding season was, overall, not good for Norwegian seabirds (Table 1a) with a third of the populations having a poor breeding success, as was the case in 2017. Fortunately, several populations did do well (38% compared to 34% in 2017). When comparing pelagic and coastal populations, the former were more successful (43% good, 22% poor) than the coastal (33% good, 33% poor). Among the pelagic species, northern gannets and razorbills fared best with a good breeding success recorded in two out of two and three of four populations respectively. Common guillemots also did well with five of eight populations having good breeding success. The three puffin colonies monitored in the Barents Sea produced many chicks while at Røst breeding success was poor for the 12th year in a row. At the two other colonies in the Norwegian Sea, it was moderate. Little auks on Bjørnøya did well, but only moderately so on Spitsbergen. The fulmar’s success on Jan Mayen was good, but poor on Røst and Sklinna. Brünnich’s guillemots had a poor breeding season on Jan Mayen, a good one on Bjørnøya and a moderate one on Spitsbergen.

  • Identifier System Attack Mitigation Methodology DATE: 13 February 2017 Identifier System Attack Mitigation Methodology
    Identifier System Attack Mitigation Methodology DATE: 13 February 2017 Identifier System Attack Mitigation Methodology Introduction This document is part of ICANN’s effort to contribute to enhancing the Stability, Security, and Resiliency (SSR) of the Internet’s system of unique identifiers (“Internet Identifiers”) by working with the Community to identify and increase awareness of related attacks and to promote broader adoption of attack mitigation practices. This effort also addresses Recommendation #12 of the Security, Stability & Resiliency (SSR) Review Team (SSR-RT) by creating an Identifier System Attack Mitigation Methodology. Specifically, this document identifies and prioritizes types of attacks against the Identifier System, providing a stepping-off point for ICANN to coordinate with the Community to develop a series of short technical documents (“Tech Notes”) on actual high-impact attacks and emerging high-risk vulnerabilities. This document will be periodically updated to reflect evolution of both the Identifier System and the cybercrime landscape, supporting on-going efforts within both ICANN and the Community to mitigate attacks that pose the greatest risk to Identifier System SSR. Authors: Lisa Phifer and David Piscitello Page 1 Identifier System Attack Mitigation Methodology DATE: 13 February 2017 Attack Mitigation Methodology ICANN is proposing a new Identifier System Attack Mitigation Methodology to: • Identify, prioritize, and periodically refresh a list of top Identifier System attacks; • Develop guidance on actual high-impact attacks and emerging high-risk vulnerabilities; • Describe corresponding attack mitigation practices that are commonly considered useful; and • Encourage broader adoption of those practices via contracts, agreements, incentives, etc. This document represents the first component of this methodology.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced.
