The Importance of Understanding Attacker Target Selection

There's a bit of a debate going on about whether the Kaseya attack exploited a 0-day vulnerability. While that's an interesting question when discussing, say, patch management strategies, I think it's less important to understand attackers' thinking than understand their target selection. In a nutshell, the attackers have outmaneuvered defenders for almost 30 years when it comes to target selection.

New Innovations in Free Space Optics

I read an article on the Finley Engineering blog that talks about new research with free-space optics. For those not familiar with the term, this means communication gear that communicates directly using light without any wires. The article talks about a Chinese team of scientists who have used light to transmit ultrahigh-definition video signals between high-rise buildings.

The Risk Factors of CDNs and Centrality

On the afternoon of June 17 of this year, there was a widespread outage of online services. In Australia, it impacted three of the country's largest banks, the national postal service, the country's reserve bank, and one airline operator. Further afield from Australia, the outage impacted the Hong Kong Stock Exchange and some US airlines. The roll call of affected services appeared to reach some 500 serv

Elon Musk Interview: SpaceX, Starlink and His Motivation and Philosophy

Elon Musk packed a lot about SpaceX and Starlink into a 32-minute interview at the 2021 Mobile World Congress and ended with a discussion of his motivation and the roles of his three companies - SpaceX, Starlink, and Neuralnk. Let's start with the SpaceX and Starlink update and conclude with the philosophy and motivation. (Scroll to the end of the post for the video of the interview).

The Infrastructure Guessing Game

As U.S. Congress inches closer to an infrastructure bill, the industry is feverously speculating how a broadband infrastructure plan might work. There is still a lot of compromise and wheeling and dealing to be done, so nobody knows how a final broadband program might work, or even definitively if there will be one. But since this is the billion-dollar question for the industry, it's worth a review of the possibilities.

Deadline of July 2 to Nominate People for Jonathan B. Postel Service Award

Do you know of someone who has made the Internet better in some way who deserves more recognition? Maybe someone who has helped extend Internet access to a large region? Or wrote widely-used programs that make the Internet more secure? Or served in some capacity behind the scenes in Internet services? Or maybe someone who has been actively working for open standards and open processes for the Internet?

A Domain Or Social Media: What Builds Consumer Trust? (A Market Research Study Conducted by the DNA)

Social media platforms like Instagram and Facebook have become key places for businesses to communicate with customers and even sell directly to consumers. Yet when it comes to actually making a purchase, do consumers trust a social media site over a domain? This is a relevant question for virtually every business. Earlier this year, we designed a survey to answer this question...

Where Did “Data Shadow” Come From?

Anyone who works in privacy is familiar with the term "data shadow": the digital record created by our transactions, our travels, our online activities. But where did the phrase come from? Who used it first? A number of authors have attributed it to Alan Westin, whose seminal book Privacy and Freedom (largely a report on the work of the Committee on Science and Law of the Association of the Bar of the City of New York) set the stage for most modern discussions of privacy.

The Deeper Root Cause of the Fastly and Akamai Outages

As we finished this article, the world was hit by another global outage by content delivery network (CDN) provider, Akamai, on June 17, 2021. The cause seems to be related to the lack of capacity to a certain "routing table" of their distributed denial of service (DDoS) mitigation. Although the technical analysis is not yet available, the central premise of this article also applies to this incident, and it serves as a timely testimony.

Capping Broadband Internet by Design

FIOS by Verizon, is a bundled Internet access, telephone, and television service that operates over a fiber-optic communications network with over 5 million customers in nine U.S. states -- providing Fiber to the Home (FTTH). One of the first service areas was a Northern Virginia community known as Ashburn -- which is also is the cloud data center capital of the world. It literally sits on top of the most massive mesh of high bandwidth, low latency fiber in existence.
