The Next New Media: Typewriters and Handwritten Letters

Who would have thought that typewriters and handwritten letters would ever be back in fashion? But back in 2013 it was reported that Russia was buying large quantities of typewriters. When this was further investigated the country denied that this was for security reasons. Since the Snowden revelations there has been a further rush on typewriters, both by government officials and by a range of, mainly corporate, businesses. more»

Verisign Mitigates 300 Gbps DDoS Attack and Other Q2 2014 DDoS Trends

It has been another busy quarter for the team that works on our DDoS Protection Services here at Verisign. As detailed in the recent release of our Q2 2014 DDoS Trends Report, from April to June of this year, we not only saw a jump in frequency and size of attacks against our customers, we witnessed the largest DDoS attack we've ever observed and mitigated -- an attack over 300 Gbps against one of our Media and Entertainment customers. more»

Six Approaches to Creating an Enterprise Cyber Intelligence Program

As few as seven years ago, cyber-threat intelligence was the purview of a small handful of practitioners, limited mostly to only the best-resourced organizations - primarily financial institutions that faced large financial losses due to cyber crime - and defense and intelligence agencies involved in computer network operations. Fast forward to today, and just about every business, large and small, is dependent on the Internet in some way for day-to-day operations, making cyber intelligence a critical component of a successful business plan. more»

Anti-Spoofing, BCP 38, and the Tragedy of the Commons

In the seminal 1968 paper "The Tragedy of the Commons" , Garrett Hardin introduced the world to an idea which eventually grew into a household phrase. In this blog article I will explore whether Hardin's tragedy applies to anti-spoofing and Distributed Denial of Service (DDoS) attacks in the Internet, or not... Hardin was a biologist and ecologist by trade, so he explains "The Tragedy of the Commons" using a field, cattle and herdsmen. more»

Some Internet Measurements

At APNIC Labs we've been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP. The intent of this particular set of data collections is to allow the data to be placed into a relative context, displaying comparison of the individual measurements at a level of geographic regions, individual countries, and individual networks. more»

What Should PGP Look Like?

Those who care about security and usability - that is, those who care about security in the real world - have long known that PGP isn't usable by most people. It's not just a lack of user-friendliness, it's downright user hostile. Nor is modern professional crypto any better. What should be done? How should crypto in general, and PGP in particular, appear to the user? I don't claim to know, but let me pose a few questions. more»

Watch LIVE: Edward Snowden at HOPE-X Today at 2:00pm EDT (18:00 UTC)

Whether you view Edward Snowden as a criminal or a hero, or somewhere in between, you cannot dispute that his revelations about pervasive surveillance have changed the discussions about the Internet on both technology and policy levels. If you are interested in hearing what Edward Snowden has to say himself, he is scheduled to speak today, Saturday, July 19, 2014, at 2:00pm US EDT at the HOPE-X conference in New York City. more»

A Great Bit of DNSSEC and DNS at IETF 90 Next Week

For those people tracking the evolution and deployment of DNSSEC or who are just interested in "DNS security" in general there is a great amount of activity happening next week at IETF 90 in Toronto. I dove into this activity in great detail in a recent post, "Rough Guide to IETF 90: DNSSEC, DANE and DNS Security", and summarized the activity in a Deploy360 post... more»

Senate Judiciary Committee Hearing on Botnet Takedowns (July 15, 2014)

The background is of course quite interesting, given how soon it has followed Microsoft's seizure of several domains belonging to Dynamic DNS provider no-ip.com for alleged complicity in hosting trojan RAT gangs, a couple of days after which the domains were subsequently returned -- without public comment -- to Vitalwerks, the operator of No-IP. This is by no means a new tactic for Microsoft, who has carried out successful seizures of various domains over the past two or three years. more»

It's Time to Talk Solutions on Mass Surveillance

The public discussion of surveillance one year on from the Snowden revelations remains a search for the biggest sinner. New stories 'outing' countries and companies are great transparency and essential for healthy societies but they have a side effect that isn't so benign: they create an evergreen source of new justifications for security services to demand more money for a surveillance and counter-surveillance arms race. more»

Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more»

Is Your New TLD Protected Against Phishing and Malware?

Until now, the criminals behind malware and phishing have had only 22 generic top-level domain names (TLDs) to abuse -- names like .com, .net or .org. But with hundreds of new TLDs entering the marketplace, e.g. .buzz, .email, and .shop, there are many more targets than ever... What can attackers do with domain names? more»

Do I need DDoS protection? A Realistic Look at the Decision Process

There has been a recent spate of well publicised Distributed Denial of Service (DDoS) attacks that bring websites down and render them useless, including Evernote and most recently Feedly. In light of this, here are some comments and tips to help companies evaluate and prepare not to be held for ransom or suffer lost reputation and sales as a result. more»
