Unexpected Effects of the 2018 Root Zone KSK Rollover

March 22, 2019, saw the completion of the final important step in the Key Signing Key (KSK) rollover - a process which began about a year and half ago. What may be less well known is that post rollover, and until just a couple days ago, Verisign was receiving a dramatically increasing number of root DNSKEY queries, to the tune of 75 times higher than previously observed, and accounting for ~7 percent of all transactions at the root servers we operate. more

Twitter Taken Down by DDoS Attack, Company Confirms

The Twitter micro-blogging service was knocked offline this morning for several hours as a result of a denial of service attack (DDoS). Twitter has confirmed and reported the attack in a post on its official blog earlier today: "We are defending against this [DDos] attack now and will continue to update our status blog as we continue to defend and later investigate." The company later reported that the service as been resumed but they are still continuing to defend against and recover from this attack. No further updates have been provided yet. more

Digital Governance in 2023: Revisiting ‘1998 Deals’ and 12 Main Trends

At the beginning of 2023, the good news is that, in spite of all geopolitical tensions, the Internet infrastructure built around TCP/IP continues to carry emails, web pages, videos, and podcasts across the globe. Technically, the Internet remains robust. The bad news is that more and more digital borders will continue to affect the global nature of international digital communication... more

Let’s Be Careful Out There: Bogus Windows Domains

Last week, my colleagues over at Sunbelt Software discovered a bogus Windows domain being registered earlier this month (where the "w" in "windows" is actually two "v"s). Today, I've been alerted to the fact that are several additional Windows domains which have registered where the "w"s have been also been replaced with "v"s... more

How to Manage and Secure Big Data

Several developments are coming together in cloud computing that are creating shockwaves throughout society and in the economy. Over the last five years we have seen the debate about cloud computing hotting up. There was the hype around the new development at the same time as warnings regarding security and privacy, and for a while the market seemed subdued about the new development. However the economic reality of cloud computing meant that enterprises and government bureaucracies had little choice but to move ahead with cloud computing... more

Public Private Cooperation: The Zeus Take Down Example

Microsoft took down a Zeus botnet recently. Within days it was publicly accosted by Fox-IT's director Ronald Prins for obstructing ongoing investigations and having used Fox-IT's data. This was followed by the accusation that Microsoft obstructs criminal proceedings... On top of all this EU Commissioner Cecilia Malmström announced that cooperation between law enforcement and industry will be forged in the European Cyber Crime Centre as of 2013. Coincidences do not exist. Why? more

Israeli Officials Dispute Claims of Stuxnet’s Joint US/Israel Effort

A few weeks ago, the New York Times published an article saying that the Stuxnet worm, which infected a large number of Iran's nuclear power plants, was a joint effort between the United States and Israel. The program began under former president George W. Bush and continued under President Obama. Last month, the Washington Post ran an article saying that the US and Israel collaborated in a joint effort to develop Flame and that work included Stuxnet. more

IETF Chair’s Statement On Security, Privacy And Widespread Internet Monitoring

This weekend Jari Arkko, Chair of the Internet Engineering Task Force (IETF), and Stephen Farrell, IETF Security Area Director, published a joint statement on the IETF blog titled: "Security and Pervasive Monitoring"... They go on to outline some of the IETF's general principles around security and privacy as well as some of the new developments. They also point out a vigorous (and still ongoing) discussion within the IETF around how to improve the security of the Internet in light of recent disclosures. more

More on Networks and Nationalization With Respect to Cyberwar

As a follow up to Susan Brenner's Networks and Nationalization and my comment there, I will go further in this post and talk about the "cyberwar" and "offense" aspects of her article. I think I made this point elsewhere as well... but before getting into a war, it'd be a brilliant idea to actually know that you can win. Cyberwarfare is the sort of game where you don't really need to be a huge government with the largest standing army in the world and sophisticated weaponry in order to win... more

First Leap to Secure Linguistic Internet - Arabic SSL Certificates Launched

Linguistic Internet is becoming stronger with the first leap to develop non-Latin applications, as Arabic Language SSL Certificates has been launched by M/s ArabicSSL with the support of Live Multilingual Translator and The Multilingual Internet Group. This step is highly appreciable because this will ensure the security and stability and develop trust over new Internet layers of Internationalized Domains (IDN TLDs). more

DNS Survey Results Pandora’s Box of Both Frightening and Hopeful Results, Says Cricket Liu

The fifth-annual survey of domain name servers (DNS) on the public Internet -- called a "Pandora's box of both frightening and hopeful results" -- was released today by The Measurement Factory in partnership with Infoblox. more

The Future of Cyber Warfare

Every now and then I get emails from readers of my blog. I mostly reply to them in private, but I recently got one question where I thought my reply might be of general interest. I took the liberty of editing the question somewhat, but in essence it was: "If you have any insight you can share with my class on cyber warfare and security, I would be delighted on hearing it." In general, I think that it's an obvious conclusion that both offensive and defensive actions with regard to national telecommunications infrastructure is becoming an integral part of a nations security assessments.... more

The Real Uneven Playing Field of Name Collisions

Recent comments on the name collisions issue in the new gTLD program raise a question about the differences between established and new gTLDs with respect to name collisions, and whether they're on an even playing field with one another. Verisign's latest public comments on ICANN's "Mitigating the Risk of DNS Namespace Collisions" Phase One Report, in answering the question, suggest that the playing field the industry should be concerned about is actually in a different place. The following points are excerpted from the comments submitted April 21. more

Security is a System Property

There's lots of security advice in the press: keep your systems patched, use a password manager, don't click on links in email, etc. But there's one thing these adages omit: an attacker who is targeting you, rather than whoever falls for the phishing email, won't be stopped by one defensive measure. Rather, they'll go after the weakest part of your defenses. You have to protect everything -- including things you hadn't realized were relevant. more

Thinking Ahead on Privacy in the Domain Name System

Earlier this year, I wrote about a recent enhancement to privacy in the Domain Name System (DNS) called qname-minimization. Following the principle of minimum disclosure, this enhancement reduces the information content of a DNS query to the minimum necessary to get either an authoritative response from a name server, or a referral to another name server. more
