Searching for Truth in DKIM: Part 3 of 5

Last year, MAAWG published a white paper titled Trust in Email Begins with Authentication [PDF], which explains that authentication (DKIM) is “[a] safe means of identifying a participant-such as an author or an operator of an email service” while reputation is a “means of assessing their trustworthiness.”

Over 75% of All Top-Level Domains (TLDs) Now Signed With DNSSEC

As I was entering in data for the weekly DNSSEC Deployment Maps, I was struck by the fact that we are now at the point where 617 of the 795 top-level domains (TLDs) are now signed with DNSSEC. You can see this easily at Rick Lamb's DNSSEC statistics site...Now, granted, most of that amazing growth in the chart is because all of the "new generic TLDs" (newgTLDs) are required to be signed with DNSSEC, but we are still seeing solid growth around the world. more

Online Drug Traffic and Registrar Policy

Last month I published an article called "What's Driving Spam and Domain Fraud? Illicit Drug Traffic" which explained how the many of the troublesome online crime issues are related to the online sale of narcotics and dodgy pharmaceuticals. Since this article was published we have witnessed one of the largest international law enforcement efforts against online drug traffic (Operation Pangea II)... more

Cryptography is Hard

In the debate about "exceptional access" to encrypted conversations, law enforcement says they need such access to prevent and solve crimes; cryptographers, on the other hand, keep saying it's too complicated to do safely. That claim is sometimes met with skepticism: what's so hard about encryption? After all, you learn someone's key and just start encrypting, right? I wish it were that simple - but it's not. more

Dell Loses Key Customer Support Domain Name for a Month, Site Exposed to Questionable Content

Client-based WDS: Providing Application Acceleration in Mobile and VPN Environments

Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more

DNS Privacy at IETF 104

From time to time the IETF seriously grapples with its role with respect to technology relating to users' privacy. Should the IETF publish standard specifications of technologies that facilitate third-party eavesdropping on communications or should it refrain from working on such technologies? Should the IETF take further steps and publish standard specifications of technologies that directly impede various forms of third party eavesdropping on communications? more

P2P as a New Spam Medium, Moving From PoC to Full Operations

Spam on P2P networks used to be mainly with advertising inside downloaded movies and pictures (mainly pornographic in nature), as well as by hiding viruses and other malware in downloaded warez and most any other file type (from zip archives to movie files). Further, P2P networks were in the past used for harvesting by spammers. Today, P2P has become a direct to customer spamvertizing medium. This has been an ongoing change for a while. As we speak, it is moving from a proof of concept trial to a full spread of spam, day in, day out... more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

How Hard Is It to Deploy DKIM?

It's coming up on two years since the DomainKeys Identified Mail (DKIM) standard was published. While we're seeing a certain amount of signed mail from Google, Paypal, and ESPs, there's still a long way to go. How hard is it to sign your mail with DKIM? The major hurdle might seem to be getting mail software that can sign outgoing mail. more

Wow! BIND9 9.10 Is out, and What a List of Features!

Today the e-mail faerie brought news of the release of BIND9 9.10.0 which can be downloaded from here. BIND9 is the most popular name server on the Internet and has been ever since taking that title away from BIND8 which had a few years earlier taken it from BIND4. I used to work on BIND, and I founded ISC, the home of BIND, and even though I left ISC in July 2013 to launch a commercial security startup company, I remain a fan of both ISC and BIND. more
