How can the open standards organizations of the IETF and W3C "strengthen the Internet" against large-scale pervasive monitoring? That is the topic up for discussion at the "Strengthening the Internet Against Pervasive Monitoring (STRINT)" workshop planned for February 28 and March 1, 2014, and jointly sponsored by the Internet Architecture Board (IAB) and the W3C. The workshop is by invitation-only and has a deadline of Monday, January 20, 2014 (by 11:59 UTC) for submission of either position papers or Internet drafts. more
Jim Cowie of Renesys reports: Traffic interception has certainly been a hot topic in 2013. The world has been focused on interception carried out the old fashioned way, by getting into the right buildings and listening to the right cables. But there's actually been a significant uptick this year in a completely different kind of attack. more
The Internet Governance Forum in Bali is not without excitement as usual. There is a rumour about a power grab by the technical community. If the "power grab" is true, then I am assuming that this is a response to threats of institutional frameworks governing or interfering with the current status quo. Personally, I feel that this is anti thesis to "enhanced cooperation". If for some reason, ICANN or the US Government is behind the scenes in instigating this move, then I would suggest that it is very bad strategy and will cause more damage than harm to the current status quo. more
Google today announced an initiative called "Project Shield", aimed at using its infrastructure to protect free expression online. "The service currently combines Google's DDoS mitigation technologies and Page Speed Service (PSS), which allow websites to serve their content through Google to be better protected from DDoS attacks." Google is currently seeking "trusted testers" and people with sites that serve media, elections and human rights-related content. more
I often think there are only two types of stories about the Internet. One is a continuing story of prodigious technology that continues to shrink in physical size and at the same time continue to dazzle and amaze us... The other is a darker evolving story of the associated vulnerabilities of this technology where we've seen "hacking" turn into organised crime and from there into a scale of sophistication that is sometimes termed "cyber warfare". And in this same darker theme one could add the current set of stories about various forms of state sponsored surveillance and espionage on the net. more
In support of National Cyber Security Awareness Month, DDoS Awareness Day is a virtual, global event focused on raising awareness and education around the threat of DDoS attacks. Hosted by Neustar with and exclusive media partner CSO, DDoS Awareness Day brings together top experts in global security to share their views, technical tips and from-the-trenches experience. Attendees will also be given access to a wealth of DDoS materials: white papers, surveys, presentations, best practices and more. more
Previous posts (Part 1 and Part 2) offer background on DNS amplification attacks being observed around the world. These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification. Response Rate Limiting (RRL) was developed to respond to these early attacks. RRL, as the name suggests, is deployed on authoritative servers to rate limit responses to target names. more
There are some real problems in DNS, related to the general absence of Source Address Validation (SAV) on many networks connected to the Internet. The core of the Internet is aware of destinations but blind to sources. If an attacker on ISP A wants to forge the source IP address of someone at University B when transmitting a packet toward Company C, that packet is likely be delivered complete and intact, including its forged IP source address. Many otherwise sensible people spend a lot of time and airline miles trying to improve this situation... The problems created for the Domain Name System (DNS) by the general lack of SAV are simply hellish. more
Geoff Huston's recent post about the rise of DNS amplification attacks offers excellent perspective on the issue. Major incidents like the Spamhaus attack Geoff mentions at the beginning of his post make headlines, but even small attacks create noticeable floods of traffic. These attacks are easy to launch and effective even with relatively modest resources and we see evidence they're occurring regularly. Although DNS servers are not usually the target of these attacks the increase in traffic and larger response sizes typically stress DNS infrastructure and require attention from operation teams. more
Most people - mistakenly - believe that they are perfectly safe behind a firewall, network address translation (NAT) device or proxy. The fact is quite the opposite: if you can get out of your network, someone else can get in. Attackers often seek to compromise the weakest link in a network and then use that access to attack the network from the inside, commonly known as a "pivot-and-attack." more
My blog 'What PRISM, credit card hacking and Chromecast have to do with FttH' led to some very interesting discussions all around the world. One of issues that was discussed was that the sheer capacity of FttH will also allow hackers, criminals and others to use that massive capacity for the wrong reasons. Its volume will make it increasingly difficult to police. 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
In part one of this post we introduced the cyber response curve. In this post, we have outlined some observations which illustrate how different level of maturity and approaches can affect your cyber response curve. 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
