Recently the 2013 revisions of the internationally acclaimed standard for information security management, ISO27001 and accompanying 27002, 'Code of practice for information security management controls' were released. Whether you're new to this or are looking for a smooth transition, it's important to reflect on the changes made. Being compliant with the latest information security standards is becoming more and more important these days. more
Many years ago on my first trip to London, I encountered for the first time signs that warned pedestrians that vehicles might be approaching in a different direction than they were accustomed to in their home countries, given the left-versus-right-side driving patterns around the world. (I wrote a while back about one notable change from left-to-right, the Swedish "H Day," as a comment on the IPv6 transition.) more
A recent research seems to indicate that financial industries should increase the security standards they use for their mobile home banking solutions. IOActive Labs recently performed a black box and static analysis of worldwide mobile home banking apps. The research used iPhone/iPad devices to test a total of 40 home banking apps from the top 60 most influential banks in the world. 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
ICANN's second level domain (SLD) blocking proposal includes a provision that a party may demonstrate that an SLD not in the initial sample set could cause "severe harm," and that SLD can potentially be blocked for a certain period of time. The extent to which that provision would need to be exercised remains to be determined. However, given the concerns outlined in Part 2 and Part 3 of this series, it seems likely that there could be many additions (and deletions!) from the blocked list given the lack of correlation between the DITL data and actual at-risk queries. 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
As discussed in the several studies on name collisions published to date, determining which queries are at risk, and thus how to mitigate the risk, requires qualitative analysis. Blocking a second level domain (SLD) simply on the basis that it was queried for in a past sample set runs a significant risk of false positives. SLDs that could have been delegated safely may be excluded on quantitative evidence alone, limiting the value of the new gTLD until the status of the SLD can be proven otherwise. more
For several years, DNS-OARC has been collecting DNS query data "from busy and interesting DNS name servers" as part of an annual "Day-in-the-Life" (DITL) effort (an effort originated by CAIDA in 2002) that I discussed in the first blog post in this series. DNS-OARC currently offers eight such data sets, covering the queries to many but not all of the 13 DNS root servers (and some non-root data) over a two-day period or longer each year from 2006 to present. more
The Latin America and Caribbean Domain Name System (LAC DNS) Forum will be held on November 15, 2013 in Buenos Aires, Argentina. This follows on a similar initiative that took place at ICANN 47 in Durban, South Africa. The event's global, regional and local organizers plan to address key online issues, including more regional involvement with Internet governance. more
Internet security has been a primary focus this week for more than 1100 engineers and technologists from around the world gathered at the 88th meeting of the Internet Engineering Task Force (IETF). Participants are rethinking approaches to security across a wide range of technical areas. more
As widely discussed recently, observed within the ICANN community several years ago, and anticipated in the broader technical community even earlier, the introduction of a new generic top-level domain (gTLD) at the global DNS root could result in name collisions with previously installed systems. Such systems sometimes send queries to the global DNS with domain name suffixes that, under reasonable assumptions at the time the systems were designed, may not have been expected to be delegated as gTLDs. more
It is a safe assumption that if you are reading this post, you like technology. If that is the case, then you understand the tremendous economic, cultural, and human rights benefits an open, universal, and free Internet provides. That freedom is under attack. And it is our responsibilities, as stakeholders in a successful Internet, to balance governments and have an open dialog on the topic. more
DNS tunneling -- the ability to encode the data of other programs or protocols in DNS queries and responses -- has been a concern since the late 1990s. If you don't follow DNS closely, however, DNS tunneling likely isn't an issue you would be familiar with. Originally, DNS tunneling was designed simply to bypass the captive portals of Wi-Fi providers, but as with many things on the Web it can be used for nefarious purposes. For many organizations, tunneling isn't even a known suspect and therefore a significant security risk. more
John Crain has been named ICANN's new Chief Security, Stability and Resiliency Officer. In this newly created position Crain will assume the responsibilities of Jeff Moss, who announced he is stepping down from his position as Chief Security Officer at the end of the year. more
