IPv6 Security Myth #4: IPv6 Networks are Too Big to Scan

Here we are, all the way up to Myth #4! That makes this the 4th installment of our 10 part series on the top IPv6 Security Myths. This myth is one of my favorite myths to bust when speaking with folks around the world. The reason for that is how many otherwise well-informed and highly experienced engineers, and others, hold this myth as truth. It's understandable, really. more

IPv6 Security Myth #2: IPv6 Has Security Designed In

Today we continue with part 2 of the 10 part series on IPv6 Security Myths by debunking one of the myths I overhear people propagating out loud far too much: That you don't need to worry about security because IPv6 has it built into the protocol. In this post, we'll explore several of the reasons that this is in fact a myth and look at some harsh realities surrounding IPv6 security. more

IPv6 Security Myth #3: No IPv6 NAT Means Less Security

We're back again with part 3 in this 10 part series that seeks to bust 10 of the most common IPv6 security myths. Today's myth is a doozy. This is the only myth on our list that I have seen folks raise their voices over. For whatever reason, Network Address Translation (NAT) seems to be a polarizing force in the networking world. It also plays a role in differentiating IPv4 from IPv6. more

2009 Domain Name Year in Review

To say that it's been quite a year in the world of domain names would be an understatement. From compromised country code Top-Level Domains (ccTLD) registries, to the delay of new generic Top-Level Domains (gTLDs), some of the events of the past year have been surprising, while others could easily have been predicted. Regardless of whether you could have seen these coming, please find below my list of 2009's most important domain name events...at least, as I see them. more

Why I Want a .PAYPAL New gTLD

I use Paypal, and I am quite satisfied with how it helps me with my business: it is still a little hard to use, and I don't use all functions of the tool, but it is not so expensive, it is fast and efficient, and Paypal does not send so many emails. In one word, Paypal rocks... The only problem that I have with Paypal is the number of fake emails that I receive. Of course, I easily identify them as they come in and luckily, G Suite (Gmail) does an excellent job at blocking all spam and phishing. more

Gold Dragon Helps Olympics Malware Attacks Gain Permanent Presence on Systems, Reports McAfee

A report recently released by McAfee Advanced Threat Research (ATR) revealed a fileless attack targeting organizations involved with the Pyeongchang Olympics. more

The Internet of Things: When Sci-Fi Becomes Reality

In my last blog post I shared some of the general security challenges that come with the Internet of Things (IoT). In this post, I will focus on one particular security risk: distributed denial of service (DDoS) attacks. Even before the age of IoT, DDoS attacks have been turning multitudes of computers into botnets, attacking a single target and causing denial of services for the target's users. By "multitudes" we can be talking about thousands or even millions of victim devices. Now add IoT into the equation... more

Crack the Code: That’s a Direct Challenge

I had quite an interesting experience recently. I was hired by a company to perform a vulnerability assessment and penetration test on their network. During the initial meeting, one of the key technical staff presented me with a challenge; He handed over the NTLM hash of the domain Administrator account and challenged me to decipher it. He explained that the complexity and length of the password would prevent me from deciphering it during the time allotted for the project. He was actually quite confident in my impending failure... more

Alternative Insights on Article 28 of the NIS2 Directive

On June 9 CircleID published an insightful article by Thomas Rickert entitled "Demystifying Art 28 NIS2." In that piece Thomas set forth two alternative interpretations of Article 28(6) of NIS2, and argued that TLD registries should not be required to maintain a separate database of the registrant data under NIS2. In my view, Thomas' approach is inconsistent with the remainder of Article 28, and would not achieve the goals of NIS2 to improve cybersecurity across the EU member states. more

IPv6 Security Myth #1: I’m Not Running IPv6 so I Don’t Have to Worry

Now that IPv6 is being actively deployed around the world, security is more and more a growing concern. Unfortunately, there are still a large number of myths that plague the IPv6 security world. These are things that people state as fact but simply aren't true. While traveling the world, talking to the people who've already deployed IPv6, I've identified what I believe are the ten most common IPv6 security myths. more

CENTR Has Released an Animated Video on ccTLDs and Their Technical Role Concerning Content

Due to increased legislative interest in this topic, CENTR says there is a pressing need for comprehensive educational material on the technical capabilities of the DNS, ccTLDs and their role in the internet ecosystem. more

Evolving the Internet Through COVID-19 and Beyond

As we approach four months since the WHO declared COVID-19 to be a pandemic, and with lockdowns and other restrictions continuing in much of the world, it is worth reflecting on how the Internet has coped with the changes in its use, and on what lessons we can learn from these for the future of the network. The people and companies that build and operate the Internet are always planning for more growth in Internet traffic. more

Most Abused TLDs Put Under Spotlight by Spamhaus

TLDs such as .men and .loan are listed as some of the most abused domains in the world. Spamhaus says some domain name registrars and resellers knowingly sell high volumes of domains to bad actors for profit, and many registries do not do enough to stop or limit this endless supply of domains. more

NCUC Group Releases Nominations

The Noncommercial Users Constituency (NCUC) is the constituency group representing civil society organizations in the formation of domain name policy. In August 2004 it initiated a process to nominate people to serve on the UN Secretary-General's Working Group on Internet Governance, as representatives of civil society. Our purpose was to assist the Secretary-General to identify qualified and widely-supported individuals capable of serving on the WGIG on behalf of civil society. more

Can We Create a Secure Caller ID For VoIP?

Can we create a "secure Caller ID" for IP-based communications, a.k.a. voice-over-IP (VoIP)? And specifically for VoIP based on the Session Initiation Protocol (SIP)? Can we create a way to securely identify the origin of a call that can be used to combat robocalling, phishing and telephony denial-of-service (TDOS) attacks? That is the challenge to be undertaken by the "Secure Telephone Identity Revisited (STIR)" group meeting tomorrow morning, July 30, 2013, at 9:00 am in Berlin, Germany, as part of the 87th meeting of the Internet Engineering Task Force (IETF). more
