It was said of the Chicago stockyards that they used every part of the pig except the squeal. The same can be said of the Internet search industry. For some time, ISPs and others, including no-cost DNS provider OpenDNS, have been squeezing every last penny out of Internet search by providing alternative suggestions when users misspell the domain name of their intended Web destination. While often problematic, as Steve Loughran writes, for some client systems, it's hardly nefarious. Search is now a well-established commercial activity. For example, no-cost OpenDNS does a good job of offering corrections to users' fumbled keystrokes and otherwise makes a good college try of getting users to their intended Web sites. What is highlighted in this case is the ubiquitous and aging DNS infrastructure. WiscNet and eWEEK Labs recently teamed up to look at several vendors, including Alcatel-Lucent, BlueCat Networks and InfoBlox, to update and better...

I got DNS in my anti-spam product. And I've got anti-spam in my DNS management. This all happened while working on my "Top 10 things you should know about spam" while also putting together an RFP (Request for Proposal) for a review on DNS service tools. DNS plays a big role in identification and verification systems including DKIM (Domain Keys Identified Mail). I'm finding that DNS systems going online today may be asked to take on a bigger network over the next three to six years. Let me break this down. First, I get the sense that DNS and the more comprehensive IPAM (IP Address Management) tools will take on bigger roles as IPv6 begins to gain traction. With an ever-growing collection of devices (both physical and virtual) needing IP address service and management, DNS will move from the shadows--where it has played a reliable and remarkably understated role in...

When Network General was reanimated in 2004 I asked "is there life left for Sniffer?" Today, my news colleague Paula Musich reported that NetScout intends to acquire Network General, the once storied leader of packet capture and analysis and creator of the Sniffer product line. From all reports, the entity known as Network General has been going down in price since it was purchased by McAfee in 1997 at the beginning of the dot-com bubble. The long story short is that the combined companies became known as Network Associates, the Oakland Coliseum joined Candlestick Park and the San Francisco baseball stadium in a degrading parade of name changes and today, Network General, again, is no more. Eaten by a much smaller company, matched against fierce competitors and losing value with each pass of the hat, the question now is: can NetScout and Network General effectively join together? You can get...

Richard Bejtlich has a great review of a Chris Sanders' Practical Packet Analysis. Rather than look to Sanders' book, here are my recommendations for getting to know Wireshark and for practical protocol analysis. Wireshark & Ethereal: Network Protocol Analyzer Toolkit from Syngress. I use this book about once a month while testing in the lab. You can go just about anywhere for a better basic and reliable explanation of IP than the one given in Sanders' book. Since I think anyone interested in network security should get it, try Virtual Honeypots: From Botnet Tracking to Intrusion Detection, which I reviewed here. The Wireshark also has a good FAQ that provides information about how to use the product and what to look for in a capture....
