The Path Toward Increasing the Security of DNSSEC with Elliptic Curve Cryptography

How do we make DNSSEC even more secure through the use of elliptic curve cryptography? What are the advantages of algorithms based on elliptic curves? And what steps need to happen to make this a reality? What challenges lie in the way? Over the past few months we've been discussing these questions within the community of people implementing DNSSEC, with an aim of increasing both the security and performance of DNSSEC. more

Join Live On Sunday - 2nd Registration Operations Workshop (ROW) In Dallas

This Sunday, March 22, 2015, the second Registration Operations Workshop (ROW) will be taking place at the Fairmont Dallas hotel from 12:30 -- 4:30 pm CDT. Discussion will include extensions to EPP, new encryption initiatives and also suggestions for ways to further automate DNS interactions between registries, registrars and DNS operators, including a need to do this for DNSSEC. more

Dynamic DNS Customers, Check Your Router Settings!

There have been quite a few news stories released over the last 24 hours regarding a wide-scale compromise of 300,00 Internet gateway devices. Here's the executive summary of what happened, how to check if you are vulnerable, and what you can do to fix it... If you use any of these devices, you should check it to ensure your device has not been compromised. more

Federal Cybersecurity Best Practices: FISMA Continuous Monitoring

Studies have found only limited, insufficient agency adherence with FISMA's (Federal Information Security Management Act) continuous monitoring mandates. One survey found almost half of federal IT professionals were unaware of continuous monitoring requirements. A recent GAO report found that two-thirds of agencies "did not adequately monitor networks" to protect them "from intentional or unintentional harm." more

ICANN And The DOC Can’t

The former contract with ICANN and the US Department of Commerce (DOC) was due to expire on September 30, 2002. In the statement announcing the renewal, the DOC acknowledged that ICANN was the subject of many complaints from many sectors of the Internet community. Some of these complaints had been presented to the US Congress during a hearing held in June 2002 by a Senate Subcommittee. At the hearing, a General Accounting Office (GAO) spokesperson, Peter Guerrero, testified, noting not only that ICANN had failed in its mandate, but that the U.S. Department of Commerce was also at fault in failing to properly oversee ICANN activities. He explains... more

Getting a Handle on IDNs

Internationalized Domain Names or IDNs are back in the news. ICANN recently released a document entitled "Proposed Final Implementation for IDN ccTLD Fast Track Process"... In a nutshell, ICANN has now offered a path toward authorizing the adoption of ccTLDs in many countries' native languages. This marks a welcome advance for millions of Internet users who do not speak English or who do not use another language covered by ASCII. But with this advance comes some concerns. more

Introduction: New gTLD Security and Stability Considerations (Part 1 of 5 )

Verisign recently published a technical report on new generic top-level domain (gTLD) security and stability considerations. The initial objective of the report was to assess for Verisign's senior management our own operational preparedness for new gTLDs, as both a Registry Service Provider for approximately 200 strings, as well as a direct applicant for 14 new gTLDs... However, in cataloging internal and external risks related to the new gTLD program, we found several far-reaching and long-standing issues that need to be further explored and/or resolved with varying levels of urgency. more

Verisign Outreach Program Remediates Billions of Name Collision Queries

A name collision occurs when a user attempts to resolve a domain in one namespace, but it unexpectedly resolves in a different namespace. Name collision issues in the public global Domain Name System (DNS) cause billions of unnecessary and potentially unsafe DNS queries every day. A targeted outreach program that Verisign started in March 2020 has remediated one billion queries per day to the A and J root name servers, via 46 collision strings. more

Is The Term “Cyberwarfare” Overstating the Case?

At the Virus Bulletin conference last month, Andrew Lee from ESET gave a talk entitled "Cyberwar: Reality or Weapon of Mass Distraction?" In it, Lee talks about how the term "cyberwar" is thrown around a lot these days. However, he disagreed with the use of the term because it uses inflationary language and overstates the case; today's "cyberwar" is not the same as a conventional ware. more

Heartbleed: Don’t Panic

There's been a lot of ink and pixels spilled of late over the Heartbleed bug. Yes, it's serious. Yes, it potentially affects almost everyone. Yes, there are some precautions you should take. But there's good news, too: for many people, it's a non-event. Heartbleed allows an attacker to recover a random memory area from a web or email server running certain versions of OpenSSL. The question is what's in that memory. It may be nothing, or it may contain user passwords (this has reportedly been seen on Yahoo's mail service), cryptographic keys, etc. more

ICANN and the Virtues of Deliberative Policymaking - Part II

In the second part of this two-part series article (part one here), Andrew McLaughlin concludes his critical look at the recently reported study, Public Participation in ICANN, by John Palfrey, Clifford Chen, Sam Hwang, and Noah Eisenkraft at the Berkman Center for Internet & Society at Harvard Law School... "ICANN has never attempted to be -- and was never designed to be -- 'representative' of the worldwide Internet community in any mathematically precise way. In view of the vast size of the global population of Internet users, and the specialized technical focus of ICANN's policy-making responsibilities, it would be a hopeless task to try to achieve truly representative statistical proportionality among ICANN's participants, committees, task forces, or Board members. Rather, here's how the U.S. government's foundational 1998 DNS policy statement described the core principle of 'representation'." more

Peering into Fast Flux Botnet Activity

Together with Thorsten Holz, I recently published a paper on fast flux botnet behaviors, "As the Net Churns: Fast-Flux Botnet Observations," based on data we gathered in our ATLAS platform. Fast flux service networks utilize botnets to distribute the web servers to the infected PCs... One of the most well known fast flux botnets has been the Storm Worm botnet, which uses the zombies to spam, send out new enticements to infect users, and to host the malicious website which delivers the malcode. 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

House of Cards

Time flies. Although it was over 18 months ago, it seems just like yesterday that a small Czech provider, SuproNet, caused global Internet mayhem by making a perfectly valid (but extremely long) routing announcement. Since Internet routing is trust-based, within seconds every router in the world saw this announcement and tried to pass it on. Unfortunately, due to the size of this single message, quite a few routers choked -- resulting in widespread Internet instability. Today, over a year later, we were treated to a somewhat different version of the exact same story. more

Starting a New Conversation on Cybersecurity

The cybersecurity debate can be highly confusing at times. There is perhaps an analogy to be made between "Cybersecurity" and "The Economy". We all want to fix the economy but making progress is not an easy task. As soon as you are beyond that statement you notice that there is a lot of nuance. Issues like trust, influence, actors, and affectivity all come to play when you want to fix the Economy. The cybersecurity discourse has similar features. more
