DNS: The Basis for Billions

In the midst of "Cyber Monday", the day traditionally seen as one of the year's busiest days for online shopping, it is only appropriate to examine the importance DNS plays for online economies. With DNS being at the heart of Internet connectivity it is easy to understand why DNS is important to the growing health of economies whose online health in dollars and euros rest in the billions. more

Phishing Attack: An Open Letter to the Anti-Spam and Mailbox Operator Community

I'm sure many of you are familiar with the targeted ESP phishing attack that has been ongoing for almost a year now and has led to multiple known ESP system breaches. Return Path was recently a victim of this same attack... In short, a relatively small list of our clients' email addresses was taken from us, meaning those addresses are now the targets of the phishing campaign that are intended to compromise those client systems. more

Outlawing Botnets

The European Commission is apparently considering the promulgation and adoption of a directive that would, at least in part, criminalize botnets. As I understand it, the premise behind adopting such a directive is that since botnets are capable of inflicting "harm" on a large scale, we need to separately criminalize them. I decided to examine the need for and utility of such legislation in this post. more

FISMA Standards Could Have a Major Impact on the Private Sector

The public is taking an increasing interest in ensuring that IT assets of federal agencies are protected from cybersecurity attacks. FISMA is addressing this concern, in part, by initiating a standard setting process for continuous monitoring. The actions taken by NIST for the federal sector could have a very significant impact on the private sector because pending legislation would provide the federal government with the authority to mandate cybesecurity measures on the private sector. more

Mandatory Provision of Abuse Contact Information in WHOIS

An industry professional at Abusix is the backbone behind a proposal to improve and create better mitigation of abuse across different global internet networks. Basically, this introduces a mandatory "abuse contact" field for objects in global Whois databases. This provides a more efficient way for abuse reports to reach the correct network contact. Personally - as a Postmaster for a leading, white-label ISP, I applaud this with great happiness for multiple reasons. I also feel people who handle abuse desks, anti-abuse roles, etc. should closely follow this. more

Average Daily Malware at All Time High, Spam Lowest Since 2008

McAfee, Inc. today unveiled its McAfee Threats Report: Third Quarter 2010, which uncovered that average daily malware growth has reached its highest levels, with an average of 60,000 new pieces of malware identified per day, almost quadrupling since 2007. At the same time, spam levels decreased in volume this quarter, both globally and in local geographies. Spam hit a two year low this quarter while malware continued to soar. More than 14 million unique pieces of malware were identified in 2010, one million more than Q3 2009. more

“Capacity” - The Hidden Word?

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

Dan Kaminsky Releases Phreebird for Easy DNSSEC

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

FISMA Focus: Continuously Monitoring the Cyber-Levee

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

Study Reports .COM Domain as Riskiest, .JP Safest Country Domain

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

Broken Policies

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

U.S. Now Leading Source of Attack Traffic, Followed by China and Russia

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

The Worm and the Wiretap

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

Richard Clarke: Defend Against Cyberwar by Re-Architecting Networks, Not Buying More Technology

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

Finding the Holes in Your Application Security Blanket

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
