To those of us who have worked on crypto policy, the 1990s have become known as the Crypto Wars. The US government tried hard to control civilian use of cryptography. They tried to discourage academic research, restricted exports of cryptographic software, and -- most memorably -- pushed something called "escrowed encryption", a scheme wherein the government would have access to the short-term keys used to encrypt communications or stored files. more
Online fakes can be a lucrative business and difficult to crack down on, due to the ease and low-cost of setting up multiple virtual storefronts and the ability to obfuscate an operation's identity. A federal lawsuit filed on March 1, 2010 by Polo Ralph Lauren and VF Corp. illustrates these points and highlights many of the intricacies of an online counterfeit ring. more
Today, this is how easily "TRUST" by your users/customers can be shattered, your revenues devastated, your share value plunged into the abyss, and your business destroyed. Furthermore, conventional thinking belongs only in university libraries, not in board rooms. It is time to seriously consider other innovative Out-Of-The-Box Solutions and doing things differently, or start writing your business obituary. more
The recent announcement of a 13-year old security flaw found in an Open Source security library has renewed the debate between open source and closed source software. The library, crypt_blowfish, allows for fast two-way password encryption. The flaw introduces the potential for passwords to be easily compromised and affects PHP and a number of Linux distributions that include the crypt_blowfish library. more
A few months ago I published a blog post about Verisign's plans to increase the strength of the Zone Signing Key (ZSK) for the root zone. I'm pleased to provide this update that we have started the process to pre-publish a 2048-bit ZSK in the root zone for the first time on Sept. 20. Following that, we will publish root zones with the larger key on Oct. 1, 2016. more
Facebook alerted users today that its engineering team on Tuesday had discovered a security issue affecting almost 50 million accounts. more
Imagine a scenario. Your website analysis shows that your page has stopped receiving visitors, yet there are no complaints that your domain is unreachable. Strange, isn't it? You are certainly wondering: What's going on? Where are my customers? You see, what happened is that you are facing the consequences of the lack of domain name system (DNS) security. more
As noted in my first article of this series (see part one, two and three), security and reliability encompass holistic network assessments, vulnerability assessments and penetration testing. This month I'd like to go deeper into penetration testing; however, first, let's go back for a quick refresh before getting started. more
A few days ago, CAUCE published a blog post entitled "Epsilon Interactive breach the Fukushima of the Email Industry" on our site, and the always-excellent CircleID. A small coterie of commenters was upset by the hyperbolic nature of the headline. Fair enough, an analogy usually has a high degree of probability that it will fail, and clearly, no one has died as a result of the release of what appears to be tens of millions of people's names and email addresses. But, the two situations are analogous in many other ways, and here's why. more
The Internet as we know it and use it today -- is broken, badly broken. Yes broken so much so that we are really crazy to have any expectations of privacy or security. Yes, really. The Internet was conceived as somewhat of a utopian environment, one where we all keep our doors, windows and cars unlocked and we trust all the people and machines out there to "do the right thing...". more
I read, with some small amount of discomfort, an article by Bill Brenner on CSO Online, wherein he interviewed several other CSOs and other "Security Execs" on their opinions on the firing of Pennsylvania CISO Robert Maley. For those who haven't heard about this, Mr. Maley was fired for talking about a security incident during the recent RSA conference without approval from his bosses. more
Distributed Denial of Services (DDoS) attacks have been the frustration of information technology professionals for many years. When asked, most tell you they wish their internet service providers (ISPs) would simply provide them "clean pipes" all the time and take care of DDoS attacks upstream before they ever get to them. Unfortunately, the resources (equipment and personnel) necessary to clean Internet connections all the time are very expensive and come with several downsides. more
In a blog post, Stewart Baker proposed restricting access to sophisticated anti-virus software as a way to limit the development of sophisticated malware. It won't work, for many different and independent reasons. To understand why, though, it's necessary to understand how AV programs work. The most important technology used today is the "signature" - a set of patterns of bytes - of each virus. Every commercial AV program on the market operates on a subscription model... more
The highest court in Germany has ruled against telephone and email data retention used to track criminal networks. Melissa Eddy of the Global and Mail reports: "A law ordering data on calls made from mobile or landline telephones and e-mail exchanges be retained for six months for possible use by criminal authorities violated Germans' constitutional right to private correspondence, the Federal Constitutional Court ruled. In its ruling, the court said the law failed to sufficiently balance the need for personal privacy against that for providing security."

DomainKeys Identified Mail (DKIM) is the leading email authentication technology, supported by major ISPs including Google, AOL, and Yahoo! (who invented its predecessor), popular mail server software like Sendmail, and many of the best minds in email technology. But if you peruse the archives of the IETF DKIM mailing list, or start up a conversation at MAAWG, it might appear that there's still a lot of disagreement about what a DKIM signature actually means. more
