Security as a Major Factor for Online Consumers

There is no doubt that the number of online consumers is on a rise and that this is a trend that will not stop any time soon. Over the last couple of years, the number of digital buyers has grown by a steady 150 million each year. This number is expected to stay stable for a few more years to come. By 2020, about two billion people will be purchasing things online and making online money transactions on a regular basis. more»

The Massive Cyberattack or Chronicle of a Strike Foretold

During the last Computer Law Conference organized by ADIAR (Argentina Computer Law Association) and the Universidad Nacional de Sur, I gave a conference on the Internet of Things, cybercrime and dangerous situation presented by the lack of proper regulation -- a topic in which I have one of my research projects. At the moment some people argued that I was talking about something that might happen in a relatively distant future, dissenting with my view that the possibility was imminent.. more»

The Internet Needs a Security and Performance Upgrade

Many of you will have seen news stories that explained what was going on: a huge DDoS attack on the infrastructure of Dyn had taken down access to many large websites like Twitter. A great deal of digital ink has since been spilled in the mainstream press on the insecurity of the Internet of Things, as a botnet of webcams was being used. Here are some additional issues that might get missed in the resulting discussion. more»

A Great Collaborative Effort: Increasing the Strength of the Zone Signing Key for the Root Zone

A few weeks ago, on Oct. 1, 2016, Verisign successfully doubled the size of the cryptographic key that generates DNSSEC signatures for the internet's root zone. With this change, root zone DNS responses can be fully validated using 2048-bit RSA keys. This project involved work by numerous people within Verisign, as well as collaborations with ICANN, Internet Assigned Numbers Authority (IANA) and National Telecommunications and Information Administration (NTIA). more»

Steps on How Service Providers Can Combat CPE Fraud and Protect Network Security

Cable modem fraud can be a major source of revenue leakage for service providers. A recent study found that communication service providers lost $3 billion dollars worldwide due to cable modem cloning and fraudulent practices. To combat this problem, device provisioning solutions include mechanisms to prevent loss -- but what do you really need to protect your bottom line? more»

Maintaining Security and Stability in the Internet Ecosystem

DDoS attacks, phishing scams and malware. We battle these dark forces every day - and every day they get more sophisticated. But what worries me isn't just keeping up with them, it is keeping up with the sheer volume of devices and data that these forces can enlist in an attack. That's why we as an industry need to come together and share best practices - at the ICANN community, at the IETF and elsewhere - so collectively we are ready for the future. more»

Exploiting the Firewall Beachhead: A History of Backdoors Into Critical Infrastructure

There is no network security technology more ubiquitous than the firewall. With nearly three decades of deployment history and a growing myriad of corporate and industrial compliance policies mandating its use, no matter how irrelevant you may think a firewall is in preventing today's spectrum of cyber threats, any breached corporation found without the technology can expect to be hung, drawn, and quartered by both shareholders and industry experts alike. more»

Increasing the Strength of the Zone Signing Key for the Root Zone, Part 2

A few months ago I published a blog post about Verisign's plans to increase the strength of the Zone Signing Key (ZSK) for the root zone. I'm pleased to provide this update that we have started the process to pre-publish a 2048-bit ZSK in the root zone for the first time on Sept. 20. Following that, we will publish root zones with the larger key on Oct. 1, 2016. more»

DDOS Attackers - Who and Why?

Bruce Schneier's recent blog post, "Someone is Learning How to Take Down the Internet", reported that the incidence of DDOS attacks is on the rise. And by this he means that these attacks are on the rise both in the number of attacks and the intensity of each attack. A similar observation was made in the Versign DDOS Trends report for the second quarter of 2015, reporting that DDOS attacks are becoming more sophisticated and persistent in the second quarter of 2016. more»

Does Apple's Cloud Key Vault Answer the Key Escrow Question?

In a recent talk at Black Hat, Apple's head of security engineering (Ivan Krstić) described many security mechanisms in iOS. One in particular stood out: Apple's Cloud Key Vault, the way that Apple protects cryptographic keys stored in iCloud. A number of people have criticized Apple for this design, saying that they have effectively conceded the "Going Dark" encryption debate to the FBI. They didn't, and what they did was done for very valid business reasons -- but they're taking a serious risk... more»
