How the Verified Mark Certificate (VMC) Makes the Mailbox Safer

Nowadays, with increasing digitalization and internet usage, email is a central communication tool. This holds true even despite the high popularity of instant messaging apps and social media. Email remains the favorite means of business communication worldwide, both in B2B and B2C. In 2019, 293.6 billion emails were sent and received. By 2025, this number will grow even more. It is predicted that we will send and receive 376.4 billion emails per day. In this scenario, implementing security features for email communications has become absolutely essential. more

The State of RPKI as We Enter 2022

Resource Public Key Infrastructure (RPKI) is a method to secure internet routing traffic by cryptographically verifying routes. As we begin 2022, we look back at 2021 and see how the year saw another significant step towards its adoption. High-profile issues with the old trust-based model of Border Gateway Protocol, designed several decades ago, have shown the continued importance of protecting popular networks from mistakes or hackers. more

New Research from CSC on the Impact of COVID-19 on Internet Security and Safety

Hackers are using company domain names for malicious attacks more than ever before. Established research shows that phishing and related malware attacks most commonly occur from a compromised or hijacked legitimate domain name, a maliciously registered, confusingly similar domain name, or via email header spoofing. Domain security intelligence is the first line of defense in preventing domain cyberattacks. more

The UK Seeks to Enforce Tougher Standards on MSPs

The UK government is proposing new regulations to strengthen cyber resilience in the private sector. Their intention is to expand cybersecurity rules for critical infrastructure (CI) operators to include managed service providers (MSPs), more stringent breach notification requirements, and legislation to establish the UK Cyber Security Council as the standards development organization for the cybersecurity profession. This is a welcomed development, but more details about implementation and enforcement are needed. more

Observations on Resolver Behavior During DNS Outages

When an outage affects a component of the internet infrastructure, there can often be downstream ripple effects affecting other components or services, either directly or indirectly. We would like to share our observations of this impact in the case of two recent such outages, measured at various levels of the DNS hierarchy, and discuss the resultant increase in query volume due to the behavior of recursive resolvers. more

Dissecting the 2022 UK Cyber Security Strategy: The ‘Whole of Society’ Approach

The UK government launched its 2022 Cyber Security Strategy on 15 December 2021, outlining its ambitious plans to improve the resilience of UK institutions and businesses while protecting the country's interests in cyberspace. The strategy signals a more involved approach by the government, which previously relied heavily on the private sector for leadership. The government's stated commitment to a 'whole of society' approach sounds really good on paper, but what exactly does it really mean? more

ICANN DNS Resolver Symposium – the Session Had Several Interesting Presentations That I Would Like to Comment On

ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here... The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System, by Paul Mockapetris and Kevin Dunlap, published in the proceedings of ACM SIGCOMM’88. The paper noted that by 1983 it was obvious that the shared HOSTS.TXT file was not a scalable solution... more

The Term Web3 Has Been Seized by the Crypto Market: An Internet Governance Perspective

In late 2021, the term Web3 began to increasingly appear in mainstream media outlets. This does not refer, however, to a sudden increase in interest in the Semantic Web as defined by Tim Berners-Lee, but rather to something entirely different. Enthusiasts of cryptocurrencies and nonfungible tokens (NFTs) seized this term and changed its meaning to reflect a supposed new stage of the Web, running on top of blockchains and having decentralization as its core value. To summarize the narrative being spun, the first generation of the Web afforded independence to the owners of websites, but this did not extend to the average user... more

We Must Keep Track of How Countries Will Confront Cybercrime in a New UN Convention

As a designated committee of experts prepares to draft a new treaty to combat the use of information and communications technologies in cybercrime at the UN in January 2022, it is paramount that other stakeholders oversee these discussions to avoid violating human rights on the Internet. This initiative was kickstarted by a 2019 resolution led by Russia and endorsed by other countries considered by many to behavior controversially on cybersecurity matters, such as China, Venezuela, Cambodia, North Korea, and others. more

Ongoing Community Work to Mitigate Domain Name System Security Threats

For over a decade, the Internet Corporation for Assigned Names and Numbers (ICANN) and its multi-stakeholder community have engaged in an extended dialogue on the topic of DNS abuse, and the need to define, measure and mitigate DNS-related security threats. With increasing global reliance on the internet and DNS for communication, connectivity and commerce, the members of this community have important parts to play in identifying, reporting and mitigating illegal or harmful behavior, within their respective roles and capabilities. more
