Loudmouths Wanted for ICANN WHOIS Replacement Work

TL;DR? It's worth reading, BUT, if not -- ICANN has yet another group looking at WHOIS, and there is a huge push to redact it to nothing. I spend easily half my day in WHOIS data fighting online crime, losing it would not make my job harder, it will make it impossible. PLEASE JOIN THE ICANN GROUP and help us fight back against people who are fighting in favour of crime. more»

The Internet as Weapon

One of the most striking and enduring dichotomies in the conceptualization of electronic communication networks is summed up in the phrase "the Internet as weapon." With each passing day, it seems that the strident divergence plays in the press -- the latest being Tim's lament about his "web" vision being somehow perverted. The irony is that the three challenges he identified would have been better met if he had instead pursued a career at the Little Theatre of Geneva and let SGML proceed to be implemented on OSI internets rather than refactoring it as HTML to run on DARPA internets. more»

Into the Gray Zone: Considering Active Defense

Most engineers focus on purely technical mechanisms for defending against various kinds of cyber attacks, including "the old magic bullet," the firewall. The game of cannons and walls is over, however, and the cannons have won; those who depend on walls are in for a shocking future. What is the proper response, then? What defenses are there The reality is that just like in physical warfare, the defenses will take some time to develop and articulate. more»

Digital Geneva Convention: Multilateral Treaty, Multistakeholder Implementation

Microsoft's call for a Digital Geneva Convention, outlined in Smith's blog post, has attracted the attention of the digital policy community. Only two years ago, it would have been unthinkable for an Internet company to invite governments to adopt a digital convention. Microsoft has crossed this Rubicon in global digital politics by proposing a Digital Geneva Convention which should 'commit governments to avoiding cyber-attacks that target the private sector or critical infrastructure or the use of hacking to steal intellectual property'. more»

Where Do You Start to Mitigate the Latest Destruction-Motivated Cyber Threats?

With traditional cyber strategies failing businesses and governments daily, and the rise of a new breed of destruction-motivated Poli-Cyber terrorism threatening "Survivability", what are top decision makers to do next? There is a global paradigm change in the cyber and non-cyber threat landscape, and to address it the industry has to offer innovative solutions. more»

So Long, Farewell: The Worst DDoS Attacks of 2016

The year 2016 will go down in infamy for a number of reasons. It was the year an armed militia occupied an Oregon wildlife refuge, Britain voted to Brexit, an overarching event that will simply be referred to as The Election occurred, and Justin Bieber made reluctant beliebers out of all of us. 2016 was also the worst year on record for distributed denial of service (DDoS) attacks by a margin that can only be considered massive. more»

We Urgently Need a New Internet

Let's be honest about it. Nobody -- including those very clever people that were present at its birth -- had the slightest idea what impact the internet would have in only a few decades after its invention. The internet has now penetrated every single element of our society and of our economy, and if we look at how complex, varied and historically different our societies are, it is no wonder that we are running into serious problems with the current version of our internet. more»

Blocking a DDoS Upstream

In the first post on DDoS, I considered some mechanisms to disperse an attack across multiple edges (I actually plan to return to this topic with further thoughts in a future post). The second post considered some of the ways you can scrub DDoS traffic. This post is going to complete the basic lineup of reacting to DDoS attacks by considering how to block an attack before it hits your network -- upstream. more»

Notes from NANOG 69

NANOG 69 was held in Washington DC in early February. Here are my notes from the meeting. It would not be Washington without a keynote opening talk about the broader political landscape, and NANOG certainly ticked this box with a talk on international politics and cyberspace. I did learn a new term, "kinetic warfare," though I'm not sure if I will ever have an opportunity to use it again! more»

Mitigating DDoS

Your first line of defense to any DDoS, at least on the network side, should be to disperse the traffic across as many resources as you can. Basic math implies that if you have fifteen entry points, and each entry point is capable of supporting 10g of traffic, then you should be able to simply absorb a 100g DDoS attack while still leaving 50g of overhead for real traffic... Dispersing a DDoS in this way may impact performance -- but taking bandwidth and resources down is almost always the wrong way to react to a DDoS attack. But what if you cannot, for some reason, disperse the attack? more»
