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»

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»

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»

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»

Help Us Answer: What Will the Internet Look Like in 10 Years?

What will the Internet look like in the next seven to 10 years? How will things like marketplace consolidation, changes to regulation, increases in cybercrime or the widespread deployment of the Internet of Things impact the Internet, its users and society? At the Internet Society, we are always thinking about what's next for the Internet. And now we want your help! more»

Should You Pay Ransomware Demands?

Ransomware is a huge problem for small and medium businesses, and the most important question is this: should you pay the ransom? Ransomware has proven a successful revenue generator for criminals, which means the risk to businesses will grow as ransomware becomes more sophisticated and increasing numbers of ethically challenged criminals jump on the bandwagon. more»

Internet Governance Outlook 2017: Nationalistic Hierarchies vs. Multistakeholder Networks?

Two events, which made headlines in the digital world in 2016, will probably frame the Internet Governance Agenda for 2017. October 1, 2016, the US government confirmed the IANA Stewardship transition to the global multistakeholder community. November 2, 2016, the Chinese government announced the adoption of a new cybersecurity law which will enter into force on July 1, 2017. more»

There are Reports of Widespread Post-Election Spear Phishing Campaigns Targeting Think Tanks, NGOs

In the wake of the 2016 United States Presidential Election, not even six hours after Donald Trump became the nation's President-Elect, an advanced persistent threat (APT) group launched a series of coordinated and well-planned spear phishing campaigns. more»

Selling DONA Snake Oil at the ITU

A venerable old ITU tradition got underway today. Its Telecommunication Standardization body, known as the ITU-T, gathered, as it has done every four years for much of the past 100 years in a conclave of nations, to contemplate what they should be doing at their Geneva intergovernmental standards meetings for the next four years. The gathering is called the WTSA... Old intergovernmental institutional habits still continue, so the participants are gathered in a remote location in Tunisia called Hammamet. more»

The Internet Needs a Security and Performance Upgrade

Many of you will have seen news stories that explained what was going on: a huge DDoS attack on the infrastructure of Dyn had taken down access to many large websites like Twitter. A great deal of digital ink has since been spilled in the mainstream press on the insecurity of the Internet of Things, as a botnet of webcams was being used. Here are some additional issues that might get missed in the resulting discussion. more»

Trust Isn't Easy: Drawing an Agenda from Friday's DDoS Attack and the Internet of Things

Last week, millions of infected devices directed Internet traffic to DNS service provider Dyn, resulting in a Distributed Denial of Service (DDoS) attack that took down major websites including Twitter, Amazon, Netflix, and more. In a recent blog post, security expert Bruce Schneier argued that "someone has been probing the defences of the companies that run critical pieces of the Internet". This attack seems to be part of that trend. This disruption begs the question: Can we trust the Internet? more»

Maintaining Security and Stability in the Internet Ecosystem

DDoS attacks, phishing scams and malware. We battle these dark forces every day - and every day they get more sophisticated. But what worries me isn't just keeping up with them, it is keeping up with the sheer volume of devices and data that these forces can enlist in an attack. That's why we as an industry need to come together and share best practices - at the ICANN community, at the IETF and elsewhere - so collectively we are ready for the future. more»

DDOS Attackers - Who and Why?

Bruce Schneier's recent blog post, "Someone is Learning How to Take Down the Internet", reported that the incidence of DDOS attacks is on the rise. And by this he means that these attacks are on the rise both in the number of attacks and the intensity of each attack. A similar observation was made in the Versign DDOS Trends report for the second quarter of 2015, reporting that DDOS attacks are becoming more sophisticated and persistent in the second quarter of 2016. more»

Writing the Next Chapter for the Historic One-Time Pad

The OTP, or One-Time Pad, also known as the Vernam cipher, is, according to the NSA, "perhaps one of the most important in the history of cryptography." If executed correctly, it provides uncrackable encryption. It has an interesting and storied history, dating back to the 1880s, when Frank Miller, a Yale graduate, invented the idea of the OTP. Communication was expensive and difficult in the age of telegrams, and few messages were easily encrypted. more»
