Given that I've written here about the original call for papers for the W3C/IAB "Strengthening The Internet Against Pervasive Monitoring (STRINT)" Workshop and then subsequently that the STRINT submitted papers were publicly available, I feel compelled to close the loop and note that a report about the STRINT workshop has been publicly published as an Internet-draft. more
According to a 2013 TwinStrata survey, 46 percent of organizations use cloud storage services and 38 percent plan to adopt this technology in the near future. Cloud storage capacity demands are increasing 40 to 60 percent year-over-year, while storage density lags behind at 20 percent. The result? More data, growing demands for space and increasing security concerns. How do enterprises overcome cloud storage security challenges? more
The recent discovery of the goto fail and heartbleed bugs has prompted some public discussion on a very important topic: what advice should cryptologists give to implementors who need to use crypto? What should they do? There are three parts to the answer: don't invent things; use ordinary care; and take special care around crypto code. more
Verisign posted preliminary public comments on the "Mitigating the Risk of DNS Namespace Collisions" Phase One Report released by ICANN earlier this month. JAS Global Advisors, authors of the report contracted by ICANN, have done solid work putting together a set of recommendations to address the name collisions problem, which is not an easy one, given the uncertainty for how installed systems actually interact with the global DNS. However, there is still much work to be done. I have outlined the four main observations... more
Since the end of last year, amplification attacks have been increasingly used by attackers and received heavy media coverage. Everyday protocols not given much thought before, like Network Time Protocol (NTP), can be asked in a very short remote command to send a very large response (list of 600 clients last connected to the NTP server) to a spoofed IP address (the target) by the requestor/attacker. more
Heartbleed, for anyone who doesn't read the papers, is a serious bug in the popular OpenSSL security library. Its effects are particularly bad, because OpenSSL is so popular, used to implement the secure bit of https: secure web sites on many of the most popular web servers such as apache, nginx, and lighttpd. A few people have suggested that the problem is that OpenSSL is open source, and code this important should be left to trained professionals. They're wrong. more
There's been a lot of ink and pixels spilled of late over the Heartbleed bug. Yes, it's serious. Yes, it potentially affects almost everyone. Yes, there are some precautions you should take. But there's good news, too: for many people, it's a non-event. Heartbleed allows an attacker to recover a random memory area from a web or email server running certain versions of OpenSSL. The question is what's in that memory. It may be nothing, or it may contain user passwords (this has reportedly been seen on Yahoo's mail service), cryptographic keys, etc. more
Here at the Anti-Phishing Working Group meeting in Hong Kong, we've just released the latest APWG Global Phishing Survey. Produced by myself and my research partner Rod Rasmussen of Internet Identity, it's an in-depth look at the global phishing problem in the second half of 2013. Overall, the picture isn't pretty. There were at least 115,565 unique phishing attacks worldwide during the period. This is one of the highest semi-annual totals we've observed since we began our studies in 2007. more
The African Union's Convention on the Establishment of a Credible Legal Framework for Cyber Security in Africa (AUCC) has been the focus of debate recently.To shed light on online security issues in Africa, CIO East Africa sought the views of Ms Sophia Bekele, an internet security expert and international policy advisor over internet and ICT. more
Delegation from the European Standardization Organizations (ESOs) - CEN, CENELEC and ETSI - met with Neelie Kroes, the Vice-President of the European Commission responsible for the Digital Agenda, in Brussels yesterday (2 April 2014) discussing how to maximize the positive contribution that standards can make to enhancing internet security and protecting personal data, in order to support the successful implementation of the EU Cybersecurity Strategy. more
The Subcommittee on Communications and Technology has scheduled a hearing for Wednesday, April 2, 2014 on "Ensuring the Security, Stability, Resilience, and Freedom of the Global Internet." more
Experts and companies in the information security industry today announced the formation of the Secure Domain Foundation (SDF), a new, non-profit, community-driven organization devoted to the identification and prevention of Internet cyber crime utilizing the domain name system (DNS). more
The number one concern cited for avoiding cloud computing is security. And there is a reason for that. Cloud providers have demonstrated some spectacular failures in the past, including Amazon's near total shutdown of an entire region, Dropbox's authentication snafu, and innumerous cloud providers that go belly-up. However, in the long run, cloud computing is destined to become more secure than in-house IT. I will briefly describe two dynamics in the industry that point in that direction, with substantiating evidence. more
Earlier this week Verisign sponsored a two day conference on name collisions in the DNS. Despite the very short time frame in which it was organized, only a month from announcement to meeting, there were some very good presentations. I'll just hit some highlights here; all of the papers and slides are on their web site at namecollisions.net. Sunday morning started with a keynote by Bruce Schneier, who is not a DNS expert (and doesn't claim to be) but had some interesting observations on names in general. more
There have been quite a few news stories released over the last 24 hours regarding a wide-scale compromise of 300,00 Internet gateway devices. Here's the executive summary of what happened, how to check if you are vulnerable, and what you can do to fix it... If you use any of these devices, you should check it to ensure your device has not been compromised. more
