Extreme Vulnerability at the Edge of the Internet - A Fresh New Universal Human-Rights Problem
Feb 06, 2014 10:55 AM PST
By design, the Internet core is stupid, and the edge is smart. This design decision has enabled the Internet's wildcat growth, since without complexity the core can grow at the speed of demand. On the downside, the decision to put all smartness at the edge means we're at the mercy of scale when it comes to the quality of the Internet's aggregate traffic load. Not all device and software builders have the skills - and the quality assurance budgets - that something the size of the Internet deserves. more»

Most people, even seasoned IT professionals, don't give DNS (the Domain Name System) the attention it deserves. As TCP/IP has become the dominant networking protocol, so has the use of DNS... Due to the reliability built into the fundamental RFC-based design of DNS, most IT professionals don't spend much time worrying about it. This can be a huge mistake! more»

In Part One of this series, we examined internal server, network and infrastructure monitoring applications. Now let's take a look at another way to capture DDoS information: external performance monitoring... Unlike network/infrastructure tools - which are usually installed inside a customer's network - external performance monitoring solutions are typically provided by a third party and leverage monitoring locations from around the world. more»

Most cloud DDoS mitigation services are offered on demand meaning that customers can enable the service when they are the victim of a DDoS attack. But how can a company find out -- quickly -- that it is under attack? Sometimes it is difficult to know. In this three part series, we will examine multiple monitoring tools companies can use to capture DDoS, which can help determine whether you are under a DDoS attack. more»

With the holiday shopping season quickly approaching, Internet retailers are gearing up for an onslaught of Web traffic - which is great, as long as they have the right measures in place to keep their customers safe and satisfied. Even one hour of downtime due to a website outage or a malicious attack can have significant impact on a retailer's reputation and revenue, especially during the holidays, a time which the National Retail Federation says can add up to 40 percent of an online retailer's annual revenue. more»

One of the most prominent denial of service attacks in recent months was one that occurred in March 2013 between Cloudflare and Spamhaus... How did the attackers generate such massive volumes of attack traffic? The answer lies in the Domain Name System (DNS). The attackers asked about domain names, and the DNS system answered. Something we all do all of the time of the Internet. So how can a conventional activity of translating a domain name into an IP address be turned into a massive attack? more»

The world of Internet threats has changed continually over the years. From the time that a "worm" first showed up in the wild, or whenever someone penetrated a system without authorization for the first time, various forms of attacks and malware have presented dangers to the system and those who use it. Different vectors have received varied focus over the years... Many parts of the Internet community have been involved in addressing relevant issues and fostering efforts to combat them. more»

As more people are realizing that in today's cyber climate Distributed Denial of Service (DDoS) attacks are a matter of when, not if, the most common question I get asked is "What can I do to prepare?" I like to break it down into 5 key steps enterprises can take now to be prepared for a future attack... It would take a book to cover all of these topics in depth. Hopefully this will at least give you, some things to think about and plan for with your DDoS mitigation strategy. more»

Many cyber attacks against companies today go unreported, and more still are undetected... Timing and context are everything. The faster a company identifies a problem, and the faster and deeper it is understood and its relevance to the business, the more effectively the company can respond. We call this squeezing the cyber response curve. This two-part post will discuss the current state of cyber threats, what the cyber response curve is and its impact your organization and how you can effectively squeeze this curve to improve attack response. more»

Since last fall, several waves of distributed denial of service (DDoS) attacks have targeted major players in the U.S. banking industry. JPMorgan Chase, Wells Fargo and PNC were among the first to sustain intermittent damage. Eventually, the top 50 institutions found themselves in the crosshairs... In the months to come, security experts would praise the banks' collective response, from heightened DDoS protection to candid customer communications.. these larger institutions have learned some painful lessons that smaller firms might heed as they seek to minimize risks. more»

"We need to break down silos", is a phrase often heard in national and international meetings around cyber security and enforcing cyber crime. So it is no coincidence that at the upcoming NLIGF (Netherlands Internet Governance Forum), the IGF, but also an EU driven event like ICT 2013 have "Breaking down silos" and "Building bridges" on the agenda. But what does it mean? And how to do so? more»

This week bank costumers of The Netherlands were shocked when they realised that online banking may not be as safe as they thought. Perhaps some were surprised to hear that what they think is money, is nothing but digits, something that does not exist. Their money only exist because we all act as if it exists and accept transactions between each other aided by software run by banks, if they haven't outsourced that function. more»

Three vectors were exploited in the recent DDoS attack against Spamhaus: 1) Amplification of DNS queries through the use of DNSSEC signed data; 2) Spoofed source addresses due to lack of ingress filtering (BCP-38) on originating networks; 3) Utilisation of multiple open DNS resolvers While. 1) is unavoidable simply due to the additional data that DNSSEC produces, and 2) "should" be practised as part of any provider's network configuration, it is 3) that requires "you and I" ensure that systems are adequately configured. more»
