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

Chuck Norris Botnet and Broadband Routers

Last week Czech researchers released information on a new worm which exploits CPE devices (broadband routers) by means such as default passwords, constructing a large DDoS botnet. Today this story hit international news... The spread of insecure broadband modems (DSL and Cable) is extremely wide-spread, with numerous ISPs, large and small, whose entire (read significant portions of) broadband population is vulnerable. more

The Cycle of E-Mail Security

Stepping back from the DMARC arguments, it occurs to me that there is a predictable cycle with every new e-mail security technology... Someone invents a new way to make e-mail more secure, call it SPF or DKIM or DMARC or (this month's mini-fiasco) PGP in DANE. Each scheme has a model of the way that mail works. For some subset of e-mail, the model works great, for other mail it works less great. more

Verisign’s Preliminary Comments on ICANN’s Name Collisions Phase One Report

Verisign posted preliminary public comments on the "Mitigating the Risk of DNS Namespace Collisions" Phase One Report released by ICANN earlier this month. JAS Global Advisors, authors of the report contracted by ICANN, have done solid work putting together a set of recommendations to address the name collisions problem, which is not an easy one, given the uncertainty for how installed systems actually interact with the global DNS. However, there is still much work to be done. I have outlined the four main observations... more

The Pros and Cons of Introducing New gTLDs

Every time new concepts are introduced, much debate ensues as to the advantages and disadvantages such a change would bring forth. We've seen that happen with the launch of IPv6. Detractors and supporters rallied to make their respective arguments heard. One thing is sure though. The need for a much larger IP address space is something both parties are in agreement with. more

Minimum Disclosure: What Information Does a Name Server Need to Do Its Job?

Two principles in computer security that help bound the impact of a security compromise are the principle of least privilege and the principle of minimum disclosure or need-to-know. As described by Jerome Saltzer in a July 1974 Communications of the ACM article, Protection and the Control of Information Sharing in Multics, the principle of least privilege states, "Every program and every privileged user should operate using the least amount of privilege necessary to complete the job." more

Should We Make the Possession of Malware a Crime?

In the U.S., it is a federal crime to use malware to intentionally cause "damage without authorization" to a computer that is used in a manner that affects interstate or foreign commerce. Most, if not all, U.S. states outlaw the use of malware to cause damage, as do many countries. The Council of Europe's Convention on Cybercrime, which the United States ratified a few years ago, has a provision concerning the possession of malware. Article 6(1)(b) of the Convention requires parties to the treaty to criminalize the possession of malware "with intent that it be used for the purpose of committing" a crime involving damage to a computer or data... more

Will a Global TAR Make DNSSEC Stick?

Two US Government contractors and the National Institute of Science and Technology have released a white paper, "Statement of Needed Internet Capability," detailing possible alternatives and considerations for a Trust Anchor Repository (TAR) to support DNSSEC deployment. The document was released through the DNSSEC-Deployment Group this week with a request that it be circulated as widely as possible to gather feedback. A Trust Anchor Repository (TAR) refers to the concept of a DNS resource record store that contains secure entry point keys... more

Internet Governance: There Are No Masterplans

Please pardon me if I start this story by telling about an incident that happened to me at the Madrid airport while flying to the ICANN meetings in Rio.

It was about midnight when, after flying in from Turin, my hometown, I had to go through the passport control to reach my gate for the flight to Rio. The war between the US/UK and Iraq had started two days before, and even if the Spanish government was among its supporters, security checks were apparently proceeding as usual. Passport controls inside the EU for EU citizens usually take a few seconds, and the line ahead of me was proceeding quickly. more

Brazil: The Newest Up and Comer

The Virus Bulletin Conference last month had some good presentations, including this one by Fabio Assolini of Kaspersky. He spoke about how Brazil is the the newest up-and-comer on the cyber crime block. The tale begins with the story of Igor and Emily, two cyber criminals operating out of Brazil. Together, the two of them stole $300,000 US from a single Brazilian bank in one year. more

7 Tips to Boost BYOD Security

The bring-your-own-device (BYOD) trend continues to make corporate inroads. According to Security Intelligence, more than 60 percent of enterprises now allow or "tolerate" employee mobile device use in the workplace. But companies still have significant security concerns, especially when it comes to the specter of lost data. Here are seven tips to boost BYOD security in 2015. more

The Harsh Reality of Spam and Online Security… Should I Stay or Should I Go?

Working in the anti-spam and online malware fight can be depressing or at best invoke multiple personality disorder. We all know things are bad on the net, but if you want a dose of stark reality, check out Brian Kreb's fantastic 'Security Fix' blog on the Washington Post site... Speaking to an old friend who asked me what I was doing these days, I recently likened the fight against this relentless onslaught to having one's pinky in a dyke, and there are days when I don't even think we have a dyke! more

Cloud Security Hinges on IP Addressing

In the first part of this trilogy, I discussed the importance of automatically provisioned second generation DNS in connection with Software Defined Networking (SDN) and Software Defined Data Centre (SDDC). In the second post, I talked about IP addressing, private enterprise networks, and how DHCP does not meet the requirements of multitenant Infrastructure-as-a-Service (IaaS) cloud environments. I will now wrap up this trilogy by putting these two thesis into real-life context. more
