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

New gTLDs: The Registry Lock

Last week, The New York Times website domain was hacked by "the Syrian Electronic Army". Other famous websites faced the same attack in 2012 by the Hacker group "UGNazi" and, in 2011 by Turkish hackers. Basically, it seems that no Registrar on the Internet is safe from attack, but the launching of new gTLDs can offer new ways to mitigate these attacks. more

New gTLD Queries at the Root & Heisenberg’s Uncertainty Principle

Since Verisign published its second SSR report a few weeks back, recently updated with revision 1.1, we've been taking a deeper look at queries to the root servers that elicit "Name Error," or NXDomain responses and figured we'd share some preliminary results. Not surprisingly, promptly after publication of the Interisle Consulting Group's Name Collision in the DNS [PDF] report, a small number of the many who are impacted are aiming to discredit the report. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 1)

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

ICANN Bans Dotless Domains

Any new top level domain approved for the Internet will have to be more than just a single label. ICANN's new gTLD program committee (NGPC) has decided to ban the use of "dotless domains". TLD operators that had planned to use their new suffix as a keyword, i.e. just the string and nothing else, will now have to reconsider. more

When an IP Address Does Not Equal Individual Culpability - Breaking Glass Pictures v Does, DAZ 2013

Something bad happens online. I can tie that something-bad back to an IP address. Do I know who did the bad thing? According to the Federal District Court in Arizona, I don't. An IP address may identify the owner of an Internet access account; it does not identify who was online at that particular time and who may be responsible for the actions in question. In Breaking Glass Pictures v Does, DAZ 2013, Plaintiff brought a claim for copyright infringement, wants early discovery, but the court is refusing. more

New gTLD SSR-2: Exploratory Consumer Impact Analysis (Part 5 of 5)

Throughout this series of blog posts we've discussed a number of issues related to security, stability, and resilience of the DNS ecosystem, particularly as we approach the rollout of new gTLDs. Additionally, we highlighted a number of issues that we believe are outstanding and need to be resolved before the safe introduction of new gTLDs can occur - and we tried to provide some context as to why, all the while continuously highlighting that nearly all of these unresolved recommendations came from parties in addition to Verisign over the last several years. more

Network Security: How Attackers Gain Access from Inside

Most people - mistakenly - believe that they are perfectly safe behind a firewall, network address translation (NAT) device or proxy. The fact is quite the opposite: if you can get out of your network, someone else can get in. Attackers often seek to compromise the weakest link in a network and then use that access to attack the network from the inside, commonly known as a "pivot-and-attack." more

How Safe is FttH?

My blog 'What PRISM, credit card hacking and Chromecast have to do with FttH' led to some very interesting discussions all around the world. One of issues that was discussed was that the sheer capacity of FttH will also allow hackers, criminals and others to use that massive capacity for the wrong reasons. Its volume will make it increasingly difficult to police. more

The World of Internet Threats Is Constantly Changing

The world of Internet threats has changed continually over the years. From the time that a "worm" first showed up in the wild, or whenever someone penetrated a system without authorization for the first time, various forms of attacks and malware have presented dangers to the system and those who use it. Different vectors have received varied focus over the years... Many parts of the Internet community have been involved in addressing relevant issues and fostering efforts to combat them. more

Polish CERT Polska and NASK Pull the Plug On .pl TLD On Malicious Registrar, Domain Silver

Today we publish an overview of domains registered through Domain Silver, Inc, a registrar operating in the .pl domain. This Registrar started operating in May 2012. Since that time, the CERT Polska team started to observe a large increase in the amount of malicious domains registered in .pl and to receive many complaints concerning domains registered through Domain Silver. more

NXDOMAINS, SSAC’s SAC045, and New gTLDs (Part 4 of 5)

In 2010, ICANN's Security and Stability Advisory Committee (SSAC) published SAC045 [PDF], a report calling attention to particular problems that may arise should a new gTLD applicant use a string that has been seen with measureable (and meaningful) frequency in queries for resolution by the root system. The queries to which they referred involved invalid Top-Level Domain (TLD) queries (i.e., non-delegated strings) at the root level of DNS, queries which elicit responses commonly referred to as Name Error, or NXDomain, responses from root name servers. more

Tactics for Responding to Cyber Attacks - Squeezing Your Cyber Response-Curve: Part 2

In part one of this post we introduced the cyber response curve. In this post, we have outlined some observations which illustrate how different level of maturity and approaches can affect your cyber response curve. more

The NameSentry Report: Benchmarking Abuse Levels in the Domain Name Industry

On July 10th Architelos released the first NameSentry Report, benchmarking abuse levels in the domain name industry. For some time now, a debate has raged about the potential impact of new gTLDs on Internet safety and security, namely abusive registrations such as phishing, spam, malware, and so on. However, without benchmarking the current state, how can we realistically evaluate if new gTLDs have made any measureable difference in the level of abuse? more

Can We Create a Secure Caller ID For VoIP?

Can we create a "secure Caller ID" for IP-based communications, a.k.a. voice-over-IP (VoIP)? And specifically for VoIP based on the Session Initiation Protocol (SIP)? Can we create a way to securely identify the origin of a call that can be used to combat robocalling, phishing and telephony denial-of-service (TDOS) attacks? That is the challenge to be undertaken by the "Secure Telephone Identity Revisited (STIR)" group meeting tomorrow morning, July 30, 2013, at 9:00 am in Berlin, Germany, as part of the 87th meeting of the Internet Engineering Task Force (IETF). more
