Geoff Huston's recent post about the rise of DNS amplification attacks offers excellent perspective on the issue. Major incidents like the Spamhaus attack Geoff mentions at the beginning of his post make headlines, but even small attacks create noticeable floods of traffic. These attacks are easy to launch and effective even with relatively modest resources and we see evidence they're occurring regularly. Although DNS servers are not usually the target of these attacks the increase in traffic and larger response sizes typically stress DNS infrastructure and require attention from operation teams. more
Our systems are protected by state of the art security systems. Our SPAM filter is a hardware device that is nearly 100% effective. It also helps in protecting against Spyware and other malicious code. Our Firewall is similar to those you would find in large corporations. Our Anti-Virus system has served us well and we've not had problems with virus for years. ...Two weeks ago, I received approximately twenty e-mails requesting the review and approval of Defending The Net articles published on other sites. I thoroughly review the e-mails to make sure they seem legitimate... more

NTIA issued a Request for Comments today asking for broad input from "all interested stakeholders, including private industry, academia, civil society, and other security experts," on actions against botnets and distributed attacks. more
After attending the afternoon ICANN Security & Stability Committee meeting, I realized that the issues involved fall into several related but independent dimensions. Shy person that I am *Cough*, I have opinions in all, but I think it's worthwhile simply to be able to explain the Big Picture to media and other folks that aren't immersed in our field. In these notes, I'm trying to maintain neutrality about the issues. I do have strong opinions about most, but I'll post those separately, often dealing with one issue at a time. more
IBM today released the results from its annual X-Force 2010 Trend and Risk Report, identifying more targeted phishing, spam and mobile attacks. The report also finds cloud security continuing to evolve. "From Stuxnet to Zeus Botnets to mobile exploits, a widening variety of attack methodologies is popping up each day," says Tom Cross, threat intelligence manager, IBM X-Force. "The numerous, high profile targeted attacks in 2010 shed light on a crop of highly sophisticated cyber criminals, who may be well-funded and operating with knowledge of security vulnerabilities that no one else has. Staying ahead of these growing threats and designing software and services that are secure from the start has never been more critical." more
The capabilities IPv6 provides will enhance online security, but the shift to the new Internet address scheme may also present risks if not properly managed. Previously, Internet security was largely an after-thought for the early Internet, as its primary purpose was to facilitate open, end-to-end, any-to-any communications and information exchange for bridging and accelerating research efforts. Today, we have a much more complex online ecosystem that spans billions of users across the globe and serves not only as an engine for e-commerce, but as an engine for all commerce. more
At Verisign we take our Internet stewardship mission very seriously, so when details emerged over the past week concerning the XcodeGhost infection, researchers at Verisign iDefense wanted to help advance community research efforts related to the XcodeGhost issue, and leveraging our unique capabilities, offer a level of public service to help readers determine their current and historical level of exposure to the infection. more
What is the responsibility of the DNS? Should the DNS be responsible for policing traffic across its infrastructure? Should the blocking and blacklisting of names or throttling of query packets be the responsibility of the DNS? From experience I know my opening paragraph has started passionate debates in more than one section of this globe. We at CommunityDNS have found ourselves right in the middle of such heated debates. "Oh YES you will!", "Oh NO you will not!" more
According to Kaspersky Lab, 2011 has seen "numerous DDoS attacks with a variety of motives," many of which will "go down in the annals of cybercrime." As we look ahead to 2012, it's worth examining some of those motives to see what they portend. more
Unlike most new IETF standards, DNS over HTTPS has been a magnet for controversy since the DoH working group was chartered on 2017. The proposed standard was intended to improve the performance of address resolutions while also improving their privacy and integrity, but it's unclear that it accomplishes these goals. On the performance front, testing indicates DoH is faster than one of the alternatives, DNS over TLS (DoT). more
Neil Schwartzman writes to report: "The company announced the Yahoo! Mail Anti-Phishing Platform (YMAP) yesterday. The technology is predicated upon the use of both DKIM and Sender Policy Framework (SPF) to identify authentic messages. As part of the initiative, Yahoo! has partnered with email authenticators Authentication Metrics, eCert, Return Path, and Truedomain to provide broad-band coverage of well-known brands." more
