What is so secret about the word, "Capacity"? As I read and talk with people I realize the word, "capacity" is typically missing from the DNS discussion. "Capacity" and "Security" are the two cornerstones to maximizing DNS resilience; both of which are typically missing from the DNS discussion. Have you seen a single DNS node easily process over 863,000 queries per second? Have you seen a network routinely handle over 50Gbits/second in outbound traffic alone without breaking a sweat? more
Today marks another key step in DNSSEC deployment. Congrats to Dan Kaminsky, chief scientist at Doxpara and one of our partners on the Practice Safe DNS campaign, on the release of his new code Phreebird. Announced today at Black Hat Abu Dhabi, Phreebird Suite 1.0 is a free, easy-to-use toolkit that lets organizations "test-drive" DNSSEC deployment. more
NIST's release of their initial public draft of SP 800-137, Guide for Continuous Monitoring of Information Systems and Organizations will create a set of challenges for the federal cybersecurity community. Agencies and contractors will need to shape the document through the multi-stage revision process while continuing to implement their own continuous monitoring measures. more
Latest research suggests the world's most popular top-level domain, .COM, is also the riskiest. According to McAfee's fourth annual 'Mapping the Mal Web' report released today, 56% of all risky sites end in .COM! The study, which according to the company analyzed more than 27 million websites, also reports that while .COM is the riskiest top-level domain, the riskiest country domain is Vietnam (.VN). Japan's .JP ranks as the safest country domain for the second year in a row. more
As an email policy wonk, I think a lot about how specific policy implementations can go wrong. Sure, every policy can go wrong, or not fit a common case. A lot of people only write polices that address common cases and don't worry about the rarer cases. The problem is there are some rare cases that may cause significant harm and those cases should be addressed. Consumerist has a case up about email policy gone wrong with a clear path to harm but no policy for handling the issue. There are a couple places I see where this policy hole can be fixed. more
The U.S. became the top attack traffic source in the second quarter of 2010, accounting for 11% of observed attack traffic in total, reports Akamai in its State of the Internet Report released today. According to the report, China and Russia held the second and third place spots, accounting for just over 20% of observed attack traffic. Attack traffic from known mobile networks has been reported to be significantly more concentrated than overall observed attack traffic, with half of the observed mobile attacks coming from just three countries: Italy (25%), Brazil (18%) and Chile (7.5%). more
According to recent news reports, the administration wants new laws to require that all communications systems contain "back doors" in their cryptosystems, ways for law enforcement and intelligence agencies to be able to read messages even though they're encrypted. By chance, there have also been articles on the Stuxnet computer worm, a very sophisticated piece of malware that many people are attributing to an arm of some government. The latter story shows why cryptographic back doors, known generically as "key escrow", are a bad idea. more
In his keynote yesterday at the RSA Security Conference, former U.S. top chief counter-terrorism adviser, Richard A. Clarke, said cyberwar defence efforts need to focus on re-architecting networks not buying more technology. more
Last month, application security provider Veracode came out with a study that stated that more than half of all enterprise applications aren't secure. The company tested approximately 2,900 applications over an 18-month period, and 57 percent failed to meet Veracode's "acceptable levels" of security. While this study gained a tremendous amount of traction in the media... it does not focus on the bigger issue... more
A recent study released today suggests 53 percent of critical infrastructure providers have experienced what they perceived as politically motivated cyber attacks. According to Symantec's 2010 Critical Information Infrastructure Protection (CIP) Survey, participants claimed to have experienced such an attack on an average of 10 times in the past five years, incurring an average cost of $850,000 during a period of five years to their businesses. more
Three parallel events in US communications policy today, all reported on widely - but with a common thread. ... Law enforcement and national security officials want to make sure that they have the same ability to execute warrants and surveillance orders online that they had in the switched-telephone-circuit age -- which will mean substantial government design mandates for new software, hardware, and communications facilities. more
Majority of U.S. Federal agencies using .gov domains have not signed their DNS with DNSSEC (Domain Name Security Extensions) despite a December 2009 Federal deadline for adoption, according to the latest report by IID (Internet Identity). IID analyzed the DNS of more than 2,900 .gov domains and has released the results in its "Q3 State of DNS Report". more
Micorsoft has released a 253 page cybersecurity ebook primarily intended for teens but also serves as a useful resource for adults interested in overall understanding of various Internet security topics. more
The National Institute of Standards and Technology (NIST) issued today its first Guidelines for Smart Grid Cyber Security, which includes high-level security requirements, a framework for assessing risks, an evaluation of privacy issues at personal residences, and additional information for businesses and organizations to use as they craft strategies to protect the modernizing power grid from attacks, malicious code, cascading errors, and other threats. more
In an interview with GovInfoSecurity, Sen. Thomas Carper said that the U.S. Senate is considering attaching cybersecurity legislation to a defense authorizations bill. Though clearly a ploy to be able to say "we did something about those evil hackers" before the elections, CAUCE applauds the attempt. There can be no doubt that the United States (and many other countries) sorely needs better laws to deal with these threats. more
