UK Government Planning on New Laws for IoT Devices Including a Mandatory Security Labelling Scheme

The UK government on Wednesday announced plans to introduce new laws for internet connected devices to better enforce the inclusion of basic cybersecurity features into IoT devices. more

Google, China, and Lawful Intercept

Like many people, I was taken by surprised by Google's announcement about its threatened withdrawal from China in the wake of continued censorship and attacks that appeared to emanate from there. My immediate reaction was quite simple: "Wow". There's been a lot of speculation about just why they pulled out. Some reports noted that Google has been losing market share to Baidu... I don't think, though, that that's the whole story. more

The US Department of Defense is seeking private sector's help to "vault DOD" into the world of elastic computing, data management and analytics, cybersecurity, and machine learning. more

Information Protection for the Domain Name System: Encryption and Minimization

In previous posts in this series, I've discussed a number of applications of cryptography to the DNS, many of them related to the Domain Name System Security Extensions (DNSSEC). In this final blog post, I'll turn attention to another application that may appear at first to be the most natural, though as it turns out, may not always be the most necessary: DNS encryption. (I've also written about DNS encryption as well as minimization in a separate post on DNS information protection.) more

Demand for Cybersecurity Workers in the United States Has Nearly Doubled Since 2013

Cybersecurity job postings in the United States has nearly doubled since 2013 and is growing three times as fast as other IT roles, according to a new report from the labor market analytics firm Burning Glass Technologies. more

Wow! BIND9 9.10 Is out, and What a List of Features!

Today the e-mail faerie brought news of the release of BIND9 9.10.0 which can be downloaded from here. BIND9 is the most popular name server on the Internet and has been ever since taking that title away from BIND8 which had a few years earlier taken it from BIND4. I used to work on BIND, and I founded ISC, the home of BIND, and even though I left ISC in July 2013 to launch a commercial security startup company, I remain a fan of both ISC and BIND. more

Over 75% of All Top-Level Domains (TLDs) Now Signed With DNSSEC

As I was entering in data for the weekly DNSSEC Deployment Maps, I was struck by the fact that we are now at the point where 617 of the 795 top-level domains (TLDs) are now signed with DNSSEC. You can see this easily at Rick Lamb's DNSSEC statistics site...Now, granted, most of that amazing growth in the chart is because all of the "new generic TLDs" (newgTLDs) are required to be signed with DNSSEC, but we are still seeing solid growth around the world. more

Cryptography is Hard

In the debate about "exceptional access" to encrypted conversations, law enforcement says they need such access to prevent and solve crimes; cryptographers, on the other hand, keep saying it's too complicated to do safely. That claim is sometimes met with skepticism: what's so hard about encryption? After all, you learn someone's key and just start encrypting, right? I wish it were that simple - but it's not. more

Why Government Agencies Use Ugly, Difficult to Use Scanned PDFs - There’s More Than Meets the Eye

Sometimes, a government agency will post a PDF that doesn't contain searchable text. Most often, it's a scan of a printout. Why? Don't the NSA, the Department of Justice, etc., know how to convert Word (or whatever) directly to PDF? It turns out that they know more than some of their critics do. The reason? With a piece of paper, you know much more about what you're actually disclosing. more

Researches Demonstrate How IPv6 Attacks Can Bypass Network Intrusion Detection Systems

With the increasing popularity of IoT devices and the added interest of transition to IPv6, a whole new range of threat vectors are evolving that allow attackers to set up undetectable communications channels across networks. more

Ongoing Internet Emergency and Domain Names

There is a current ongoing Internet emergency: a critical 0day vulnerability currently exploited in the wild threatens numerous desktop systems which are being compromised and turned into bots, and the domain names hosting it are a significant part of the reason why this attack has not yet been mitigated. This incident is currently being handled by several operational groups. This past February, I sent an email to the Reg-Ops (Registrar Operations) mailing list. The email, which is quoted below, states how DNS abuse (not the DNS infrastructure) is the biggest unmitigated current vulnerability in day-to-day Internet security operations, not to mention abuse. more

Google Announces DNSSEC Support for Public DNS Service

Google today announced that its "Public DNS" service is now performing DNSSEC validation. Yunhong Gu, Team Lead for Google Public DNS, in post today wrote: "We launched Google Public DNS three years ago to help make the Internet faster and more secure.Today, we are taking a major step towards this security goal: we now fully support DNSSEC (Domain Name System Security Extensions) validation on our Google Public DNS resolvers." more
