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»

Let's Face Facts: We Need a New Industrial Internet

The Internet is a great success and an abject failure. We need a new and better one. Let me explain why. We are about to enter an era when online services are about to become embedded into pretty much every activity in life. We will become extremely dependent on the safe and secure functioning of the underlying infrastructure. Whole new industries are waiting to be born as intelligent machines, widespread robotics, and miniaturized sensors are everywhere. 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»

Considering a Vulnerability Disclosure Program? Recent Push Raises Questions for General Counsel

Several years ago, vulnerability disclosure programs, also called "bug bounty" programs, were novel and eyed with suspicion. Given sensitivities and potential liabilities, companies are wary of public disclosure and hackers seeking to exploit research. When a hacker presented a flaw to a company, the company was more likely to be concerned about taking legal action than making a public announcement or offering a reward. That is changing. more»

Domain Name Association Outlines Healthy Practices as Part of Key Initiative

The domain name system is in good health. But it's about to get even better. The Domain Name Association (DNA), the Internet domain industry's trade association, undertook an effort in 2016 it named the Healthy Domains Initiative (HDI). It's an ambitious, self-motivated effort to build on the DNS' already secure and stable platform and meet select challenges head-on, before they develop. more»

The Worrying Prospects for Digital Trade Under President Trump

US leadership and influence online stems from US innovation and corporate risk-taking. But it also is the direct result of US Government policy. In the early days of the web and e-commerce, the Clinton administration recognized they had to figure out a strategy to reconcile the internet, which is global, with laws and regulations, which are domestic. Instead of demanding negotiations for shared global rules, Administration officials put forward a set of principles, which they called the Framework for Global Electronic Commerce. more»
