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
The more I read, the more I see conflicting views on the state of the criminal cybercrime world. On the one hand, the Russian criminal cybercrime underworld is a scary, organized place... On the other hand, there is the position that that position is an exaggeration of what it is actually like and that it's a bunch of ragtag folks who have some advanced computer skills but they are not formally organized. ... I see this very similarly to how I see cyber warfare... more
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 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
It's not particularly clear whether a marketing intern thought he was being clever or a fatigued pentester thought she was being cynical when the term "Purple Team Pentest" was first thrown around like spaghetti at the fridge door, but it appears we're now stuck with the term for better or worse. Just as the definition of penetration testing has broadened to the point that we commonly label a full-scope penetration of a target's systems with the prospect of lateral compromise and social engineering as a Red Team Pentest -- delivered by a "Red Team" entity operating from a sophisticated hacker's playbook. more
In 2019, we've seen a surge in domain name system (DNS) hijacking attempts and have relayed warnings from the U.S. Cybersecurity and Infrastructure Agency, U.K.'s Cybersecurity Centre, ICANN, and other notable security experts. Although the topic has gained popularity amongst CIOs and CISOs, most companies are still overlooking important security blind spots when it comes to securing their digital assets outside the enterprise firewalls -- domains, DNS, digital certificates. more
With DNS abuse a topic of increased concern throughout the community, any controversy over adopting the Uniform Rapid Suspension System (URS) for all generic top-level domains (gTLDs) seems misplaced. The URS was designed as a narrow supplement to the Uniform Domain-Name Dispute Resolution Policy (UDRP), applicable only in certain tightly defined circumstances of clear-cut and incontrovertible trademark infringement involving the registration and use of a domain name. more
APNIC Labs, the research arm of Asia-Pacific Network Information Centre, is partnering with Cloudflare for a joint research project relating to the operation of the DNS, reports Geoff Huston, APNIC's Chief Scientist. more
A fledgling international cyber security alliance is continuing to gather backing from private business, according to a recent article published on ComputerWeekly.com. The International Cyber Security Protection Alliance (ICSPA) aims to support law enforcement agencies in countries that lack the resources to fight cybercrime. Commercial security organizations such as McAfee and Trend Micro are supporting the alliance. more
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
A team of researchers from Princeton University and the University of California has developed a machine-learning algorithm named PREDATOR that can accurately establish domain reputation at the time of domain registration. more
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
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
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
This article is the first in an occasional series on DKIM/ADSP edge cases that may not be generally recognized or understood. Many people advocate DKIM/ADSP adoption without fully recognizing potential implementation and operational issues. The fact is that the email messaging environment is fraught with opportunities for poor outcomes because of common practices that need to be considered or poorly understood implementations that are not considered... more
