With the recent attacks against high-profile New Zealand domain names including Coca-Cola.co.nz and F-Secure.co.nz, fingers are naturally pointing to Domainz, the registrar of record for these domains, as the party responsible for this lapse in security. While domain name registrars certainly need to ensure the security and stability of their systems, domain name registries must also step up and take responsibility for mitigating risks posed by hackers... more
This past February, around 100 DNS industry experts met in Atlanta, GA for the "The Global DNS Security, Stability, & Resiliency Symposium." Organized by ICANN and hosted by Georgia Tech, this event was to strengthen personal relationships between operators and review what we know about the DNS infrastructure... The content included three breakout groups over two days: Enterprise Use of DNS, DNS in Resource Constrained Environments, and Combating Malicious Use of DNS... more
Mike Hammer's thoughtful article, A Few Thoughts on the Future of Email Authentication, should trigger thoughtfulness in the rest of us. Email abuse has been around a long time. Anti-abuse efforts have too. Yet global abuse traffic has grown into the 90+% range, with no hint of trending downward. The best we hear about current effectiveness is for last-hop filtering, if you have the money, staff and skills to apply to the problem... more
Internet users are acutely aware of their exposure on the Internet and clearly concerned about their safety. Increased downloads of scareware as Conficker made headlines in the mainstream media are only the latest evidence. Desktop software is often viewed as a one-stop shop for fighting Internet threats such as viruses, worms and other forms of malware and phishing. These solutions have served us well but more protections are needed to address the dynamic and increasingly sophisticated web based exploits being launched... more
With the Online Trust Alliance Town Hall Meeting and Email Authentication Roundtable next week as well as the RSA Conference, I decided to pause and think about where we are and where we might be headed with regard to email authentication. Over the years, many of us have collectively worked to provide a framework for authenticating email... more
Four senators (Rockefeller, Bayh, Nelson, and Snowe) have recently introduced S.773, the Cybersecurity Act of 2009. While there are some good parts to the bill, many of the substantive provisions are poorly thought out at best. The bill attempts to solve non-problems, and to assume that research results can be commanded into being by virtue of an act of Congress. Beyond that, there are parts of the bill whose purpose is mysterious, or whose content bears no relation to its title. more
So this Internet thing, as we discussed in our last article, is broken. I promised to detail some of the specific things that are broken. Implicit trust is the Achilles heel of the Internet... All of the communication between the resolver and the DNS server is in plain text that can be easily seen and changed while in transit, further, the resolver completely trusts the answer that was returned... more
A cybersecurity bill introduced in the U.S. Senate on April 1st, 2009 would give the United States federal government extraordinary power over private sector Internet services, applications and software. This proposed legislation is a direct result of a review ordered by the Obama administration into government policies and processes for defending against Internet-born attack. The focus of the bill, according to a summary released by the sponsoring senators, is on establishing a new partnership between the public and private sectors in a joint effort to bolster Internet security... more
NeuStar's UltraDNS faced attack on two fronts on Tuesday, March 31. One of the attacks was technical -- a massive denial-of-service attack. The second was a rather surprising opening strike from competitor Dynamic Network Services (DynDNS), which launched a full-scale (and in T1R's opinion, misguided) public relations broadside. First, to the actual denial of service attack. Contrary to many early reports, UltraDNS was not 'down' on Tuesday... more
The market has failed to secure cyberspace. A ten-year experiment in faith-based cybersecurity has proven this beyond question. The market has failed and the failure of U.S. policies to recognize this explains why we are in crisis. The former chairman of the Security and Exchange Commission, Christopher Cox, a longtime proponent of deregulation, provided a useful summary of the issue when he said, "The last six months have made it abundantly clear that voluntary regulation does not work."... more
