India’s Draft National E-Commerce Policy: A Bollywood Drama in Four Acts

India's recently published Draft National e-Commerce Policy, prepared by the Indian Commerce Ministry think-tank, can be read like the script of a four-act Bollywood drama... They were the dream couple: Princess India and Prince IT. She was full of cultural richness and diversity, with beauty, mystique and natural resources. She also a dark side. She harbored the world's largest number of impoverished people, with little infrastructure, and facing sparse economic prospects. more

A Short History of DNS Over HTTP (So Far)

The IETF is in the midst of a vigorous debate about DNS over HTTP or DNS over HTTPS, abbreviated as DoH. How did we get there, and where do we go from here? (This is somewhat simplified, but I think the essential chronology is right.) Javascript code running in a web browser can't do DNS lookups, other than with browser.dns.resolv() to fetch an A record, or implicitly by fetching a URL which looks up a DNS A or AAAA record for the domain in the URL. more

How to Track Online Malevolent Identities in the Act

Want to be a cybersleuth and track down hackers? It may sound ambitious considering that malevolent entities are extremely clever, and tracing them requires certain skills that may not be easy to build for the typical computer user. But then again, the best defense is offense. And learning the basics of sniffing out cybercriminals may not only be necessary nowadays, it has become essential for survival on the Web. So where can you begin? more

Putting Cyber Threats Into Perspective

As society uses more digital technologies we are increasingly also faced with its problems. Most of us will have some horror stories to tell about using computers, smartphones, and the internet. But this hasn't stopped us from using the technology more and more. I believe that most people would say that their lives would be worse without technology -- in developed countries but equally in the developing world. more

Some Thought on the Paper: Practical Challenge-Response for DNS

Because the speed of DNS is so important to the performance of any connection on the 'net, a lot of thought goes into making DNS servers fast, including optimized software that can respond to queries in milliseconds, and connecting DNS servers to the 'net through high bandwidth links. To set the stage for massive DDoS attacks based in the DNS system, add a third point: DNS responses tend to be much larger than DNS queries. more

Five Inconvenient Facts about the Migration to 5G Wireless

An unprecedented disinformation campaign purposefully distorts what consumers and governments understand about the upcoming fifth generation of wireless broadband technology. A variety of company executives and their sponsored advocates want us to believe that the United States already has lost the race to 5G global market supremacy and that it can regain it only with the assistance of a compliant government and a gullible public. more

Say YES to DNSSEC

With the latest "DNSpionage" attack, ICANN astutely prompted domain name holders to fully deploy DNSSEC on their names. Afilias absolutely supports this and encourages the same. In this post, I remind you of why DNSSEC is important and our continued role. Afilias has a long history in the development and advocacy of DNSSEC. In 2007, we partnered with Public Interest Registry to help found dnssec-deployment.org. more

An Update From CIRA on IoT Security

Last April, I shared information about a multistakeholder process that CIRA is part of, which seeks to identify and guide the development of policy around the Internet of Things (IoT), putting security at the heart of internet innovations in Canada. Since the formation of this process, we've made quite a bit of progress and I'm pleased to share some of that with you. more

What Is the Most Secure VPN Protocol?

VPN products vary greatly in convenience, efficiency, and security. If security is a serious concern, an organization needs to pay close attention to the protocols a service supports. Some widely used protocols have significant weaknesses, while others offer state-of-the-art security. The best of the lot today include OpenVPN and IKEv2. What's called a VPN protocol is actually a collection of protocols. There are several functions which every VPN has to manage. more

Microsoft is Abandoning SHA-1 Hashes for Updates - But Why?

Microsoft is shipping a patch to eliminate SHA-1 hashes from its update process. There's nothing wrong with eliminating SHA-1 - but their reasoning may be very interesting. SHA-1 is a "cryptographic hash function". That is, it takes an input file of any size and outputs 20 bytes. An essential property of cryptographic hash functions is that in practice (though obviously not in theory), no two files should have the same hash value unless the files are identical. more

Building a Secure Global Network

Recently, the DNS has come under an extensive attack. The so-called "DNSpionage" campaigns have brought to light the myriad methods used to infiltrate networks. These attacks employed phishing, system hopping via key exfiltration, and software zero day exploits, illustrating that many secure networks may not be fully protected. more

NANOG's Edward Mc Nair to Deliver Keynote Address at CaribNOG 17 in April

Edward Mc Nair will deliver the keynote address at the next regional meeting of the Caribbean Network Operators Group (CaribNOG), to be held in Bridgetown, Barbados from April 10 to 12. The featured talk will take place on Thursday 11 April at 9 am AST. A live netcast will be available. Mc Nair is the Executive Director of the North American Network Operators Group (NANOG). more

Revisiting How Registrants Can Reduce the Threat of Domain Hijacking

Recent events have shown the threat of domain hijacking is very real; however, it is also largely preventable. As Verisign previously noted, there are many security controls that registrants can utilize to help strengthen their security posture. Verisign would like to reiterate this advice within the context of the recent domain hijacking reports. Domains are an important element of internet infrastructure; their functionality and security rely upon many factors such as their delegated name servers. more

As We Head to ICANN64 in Japan, Let’s Pay Attention to National and Global Context of the Region

Soon it'll be time again for some of us to pack our bags and head for the ICANN64 meeting in Kobe, Japan. Even if you plan to stay at home, it still will be helpful to understand the national and global context in which the meeting is taking place. One way to do that is by looking at Japan's Prime Minister's Shinzo Abe recent Keynote Speech at the World Economic Forum Annual Meeting, (Jan 23rd, 2019) entitled: "Toward a New Era of "Hope-Driven Economy" more

Routing Security - Getting Better, But No Reason to Rest!

In January 2018, I looked back at 2017 to figure out how routing security looked globally and on a country level. Using the same metrics and methodology, I've recently taken a look at 2018 to see if we're making improvements. The good news is, it seems like the routing system is doing better! But there is still much work to be done. Using BGPStream.com, a great public service providing information about suspicious events in the routing system, I analyzed the number of incidents... more
