“there is now a significant body of work showing how to break conventional quantum cryptography systems based on various practical weaknesses in the way they are set up…while the known loopholes can be papered over, it’s the unknown ones that represent threats in the future…[researchers have shown that it’s easy] with a little malicious intent to bend the assumptions behind perfect quantum cryptography.”
“[An IPv4 address space] black market already exists, albeit on a small scale…[currently] IPv4 addresses are still relatively easy to get…[some believe] that regional registries such as ARIN should head off a potentially deleterious black market by creating a “white market” with established rules for trading IPv4 addresses at market-established costs…But the opportunity to cleanly switch from IPv4 to IPv6 passed many years ago. The current transition strategy, called “dual stack,” requires businesses to remain connected to both IPv4 and IPv6 networks until most of the Internet gets to “the other side” — a process expected to take at least five years.”
“The 605-page [NSA IAD] PDF document reads like a listing of the pros and cons for a huge array of defensive and counterintelligence approaches and technologies that an entity might adopt in defending its networks…[one] section delves into the challenges of attributing the true origin(s) of a computer network attack”
Cyberdeterrence through tattlling? This is ridiculous. Not bloody likely that will work against serious hackers. And not bloody likely that it would be done in cases where potentially state-sponsored hackers were caught.
“A low-complexity approach for reconstructing average packet arrival rates and instantaneous packet counts at a router in a communication network, where the arrivals of packets in each flow follow a Poisson process”
Our visual network traffic monitoring software (for background information, see our website) has successfully passed our internal tests, so we are packaging a Linux-oriented beta distribution that is planned for snail-mailing (no downloads–sorry, but export regulations still apply) on a limited basis before the end of the month. The beta includes premium features that will not be available with our planned free/open-source distribution later this year, but at this early stage we will be happy to provide a special license free of charge to a limited number of qualifying US organizations.
Participants in our beta program will be expected to provide timely and useful feedback on the software, e.g.
• filling perceived gaps in documentation
• proposing and/or implementing improvements
• making feature requests or providing constructive criticism
• providing testimonial blurbs or case studies
The software should be able to run in its entirely on a dedicated x86 workstation with four or more cores and a network tap (though you may prefer to try out distributed hardware configurations). If your organization is interested in participating in our beta program, please include a sentence or two describing your anticipated use of this visual network traffic monitoring software along with your organizational background, POC and a physical address in an email to beta [at our domain name]. DVDs will only be mailed once you’ve accepted the EULA. Bear in mind that beta slots are limited. Enjoy!
“[A researcher] gave a talk on his then current project to prove a certain OS kernel was secure…they hoped in two years to have a proof of the OS’s correctness. What struck me during his talk was he could write down on the board, a [formula that] captured the notion of data security: if a certain function f had this property, then he would be able to assert his OS could not leak any information…At the end of his talk I asked him if he wanted a proof now that his function f satisfied the formula. He looked at me puzzled, as did everyone else. He pointed out his f was defined by his OS, so how could I possibly prove it satisfied his formula—the f was thousands of lines of code. He added they were working hard on proving this formula, and hoped to have a full proof in the next 24 months…I walked to the board and wrote out a short set theory proof to back up my claim—any f had his property…I thought he would be shocked. I thought he might be upset, or even embarrassed his formula was meaningless. He was not at all. [He] just said they would have to find another formula to prove.”
