Wikileaks, the CIA, and the Press

As you've probably read, WikiLeaks has released a trove of purported CIA documents describing their hacking tools. There's a lot more that will be learned, as people work their way through the documents. For now, though, I want to focus on something that's being misreported, possibly because of deliberately misleading text by WikiLeaks itself. Here's the text from WikiLeaks... more»

Three Layers of China's International Strategy on Cyberspace

China's newly released International Strategy on Cyberspace is marked by three distinctive layers with different degree of priority: (1) sovereignty (or cybersecurity, or UN Charter), (2) globalization (or digital economy, or WTO rules), and (3) fundamental freedoms (or human rights, or UDHR). The good point of the strategy is that it tries to make the three layers peacefully co-exist in one document. The failure, however, lies in the intentional ranking of relevance/importance of the three layers... 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»

Reaction: Do We Really Need a New Internet?

The other day several of us were gathered in a conference room on the 17th floor of the LinkedIn building in San Francisco, looking out of the windows as we discussed some various technical matters. All around us, there were new buildings under construction, with that tall towering crane anchored to the building in several places. We wondered how that crane was built, and considered how precise the building process seemed to be to the complete mess building a network seems to be. more»

Bug Bounty Programs: Are You Ready? (Part 3)

The Bug Bounty movement grew out a desire to recognize independent security researcher efforts in finding and disclosing bugs to the vendor. Over time the movement split into those that demanded to be compensated for the bugs they found and third-party organizations that sought to capitalize on intercepting knowledge of bugs before alerting the vulnerable vendor. Today, on a different front, new businesses have sprouted to manage bug bounties on behalf of a growing number of organizations new to the vulnerability disclosure space. more»

Mitigating the Increasing Risks of an Insecure Internet of Things

The emergence and proliferation of Internet of Things (IoT) devices on industrial, enterprise, and home networks brings with it unprecedented risk. The potential magnitude of this risk was made concrete in October 2016, when insecure Internet-connected cameras launched a distributed denial of service (DDoS) attack on Dyn, a provider of DNS service for many large online service providers (e.g., Twitter, Reddit). Although this incident caused large-scale disruption, it is noteworthy that the attack involved only a few hundred thousand endpoints... 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»
