A Survey of DNS Security: Most Vulnerable and Valuable Assets

The following provides and introduction to a study by Venugopalan Ramasubramanian and Emin Gun Sirer, called "Perils of Transitive Trust in the Domain Name System". The paper presents results from a large scale survey of DNS, illustrating how complex and subtle dependencies between names and nameservers lead to a highly insecure naming system... "It is well-known that nameservers in the Domain Name System are vulnerable to a wide range of attacks. We recently performed a large scale survey to answer some basic questions about the legacy DNS."

Wall Street Journal Article on Whois Privacy

Today's Wall Street Journal discusses the fight over Whois privacy. The article on the front page of the Marketplace section starts by discussing how the American Red Cross and eBay use the Whois database to track down scammers: "Last fall, in the wake of Hurricane Katrina, the American Red Cross used an Internet database called "Whois" that lists names and numbers of Web-site owners to shut down dozens of unauthorized Web sites that were soliciting money under the Red Cross logo. Online marketplace eBay Inc. says its investigators use Whois hundreds of times a day..."

Examining Two Well-Known Attacks on VoIP

VoIP is here to stay. In fact many incumbent telecommunication carriers have started offering VoIP service for sometime and several new VoIP service providers have emerged. Aside from issues such as quality of service, the aspect of security, or lack thereof, is misunderstood by some of the VoIP service providers. This purpose of this article is to discuss two of the most well known attacks that can be carried out in current VoIP deployments.

Reporting To God

"GOD, at least in the West, is often represented as a man with a flowing beard and sandals. Users of the Internet might be forgiven for feeling that nature is imitating art — for if the Net does have a god he is probably Jon Postel" (The Economist, Feb. 1997) David W. Maher, Senior Vice President, Law and Policy of Public Interest Registry (PIR) offers his reminiscence of the early days of the Internet and attempts made to restructure the Domain Name System — an article he has entitled 'Reporting to God'.

Report on DNS Amplification Attacks

In this newly released paper Randal Vaughn and Gadi Evron discuss the threat of Distributed Denial of Service (DDoS) attacks using recursive DNS name servers open to the world. The study is based on case studies of several attacked ISPs reported to have on a volume of 2.8Gbps. One reported event indicated attacks reaching as high as 10Gbps and used as many as 140,000 exploited name servers.

Behind the Smoke Screen of Internet and International Infrastructure

In my recent write-up I start by discussing some recent threats network operators should be aware of, such as recursive DNS attacks. Then, a bit on the state of the Internet, cooperation across different fields and how these latest threats with DDoS also relate to worms and bots, as well as spam, phishing and the immense ROI organized crime sees. I try and bring some suggestions on what can be done better, and where we as a community, as well as specifically where us, the "secret hand-shake clubs" of Internet security fail and succeed. Over-secrecy, lack of cooperation, lack of public information, and not being secret enough about what really matters.

Worm Propagation Strategies in an Ipv6 Internet

A recent paper called "Worm Propagation Strategies in an IPv6 Internet", written by Steven M. Bellovin, Angelos Keromytis, and Bill Cheswick, examines whether or not the deployment of IPv6 will in fact provide a substantial level of barrier against worms. Shared below are the introductory paragraphs from this paper. "In recent years, the internet has been plagued by a number of worms. One popular mechanism that worms use to detect vulnerable targets is random IP address-space probing..."

WIPO Crowing Again About “Cybersquatting”

Most of us would be put off if a court issued a press release cheering the number of prisoners its judges had put behind bars or the number of tenants it had helped landlords to evict. That seems antithetical to the neutral adjudication of disputes, and ethical rules regularly decry such "appearance of bias." Yet WIPO seems to think it perfectly natural to crow about its arbitrators' favoritism for complainants against "cybersquatters" in UDRP proceedings. It issued a release that reads like a solicitation for trademark claimants' business, not a promotion of neutral arbitration services...

WIPO Responds to Significant Cybersquatting Activity In 2005

In a report released today, the World Intellectual Property Organization (WIPO) has announced a 20% increase in the number of cybersquatting (abusive registration of trademarks as domain names) cases filed in 2005 as compared to 2004. The report further indicates that "in 2005, a total of 1,456 cybersquatting cases were filed with WIPO's Arbitration and Mediation Center. This increase represents the highest number of cybersquatting cases handled by the WIPO Center since 2001."

What’s in a Name?

Internet domain names are truly bizarre. There is nothing especially remarkable about them from a technical perspective, but from a social and political perspective they are all sorts of fun. We can have arguments over control of the DNS root, arguments over whether names are property, arguments over innate rights to specific names, arguments over a registrar's right (or lack thereof) to exploit unregistered names for private gain, and many more arguments besides. In this article, I'd like to explore the argument-space rather than defend any particular position in it. In so doing, I hope to illuminate some novel (or under-emphasised) perspectives on the matter.
