Root Servers Implement DNSSEC: A Major Step in Domain Security

On Wednesday (5th May) the last of the 13 authoritative root servers for the domain name system switched over to the DNS Security Extensions (DNSSEC) security protocol. DNSSEC is intended to prevent DNS exploits such as cache poisoning. All 13 root servers are now serving a signed version of the root zone. However, it is not possible to validate these signatures at present as the public key remains undisclosed.. This precautionary measure is intended to ensure that for the time being it remains possible to switch back to an unsigned root zone, should the need arise. There have been no reports of any problems in the immediate aftermath of VeriSign's J root server starting to serve DNSSEC signatures. Experts at the 60th RIPE meeting in Prague were almost unanimous in predicting a glitch-free switchover, following the successful switchovers of the other 12 root servers in recent months. The only apocalyptic note was sounded by a countdown to the demise of the unsigned root zone. Yesterday's changeover does mean the .root zone is now dead. VeriSign, which operated the master server for the root zone, has for several years used a single entry under .root, that served the purpose of checking that the bulky root zone had been transferred. According to Jaap Akkerhuis, a DNS expert at nl.netLabs, the creation of the .root entry was prompted by a complete outage of the .com zone following a data transfer error. Rigid DNSSEC procedures render this trick for root servers operated by VeriSign and the Internet Corporation for Assigned Names and Numbers (ICANN) obsolete.

Understanding Domain Hijacking Risks And Protection Strategies

Domain name hijacking broadly refers to acts where a registered domain name is misused or stolen from the rightful name holder. A domain hijacking is a security risk many organizations overlook when they develop security policy and business continuity plans. While name holders can take measures to protect their domain names against theft and loss, many measures are not generally known. . In one hijacking scenario, you begin the day as an e-merchant doing business online at 'www.onlineseller..' At 2:15 p.m. that afternoon, your visitor traffic and merchant transactions disappear. You investigate and discover someone’s impersonated your company’s administrative contact, transferred your domain name to a different registrar, and modified the DNS. Visitors to your domain name land at a hoax Web site that impersonates your virtual store. Improbable? It happened to Hushmail in April of this year. In another scenario, the email service you provide to thousands of users suddenly stops. You discover someone’s transferred your domain name to another registrar without your notice or consent. Your DNS configuration has been modified, and your user’s email is being delivered to someone else’s mail server. Hours later, your registration is restored, but only after an exhausting and frustrating incident response effort. Preposterous? It happened to PANIX back in January, 2005. Internet Corporation for Assigned Names and Numbers (ICANN) CEO Paul Twomey says that while “a domain hijacking is not as obvious a threat as spam and spyware, it can be just as disruptive to the business and operations of name holders; in extreme cases, a domain hijacking can have a lasting impact on an organization."

Comprehensive Guide on Importing BIND Zones and Setting Up Axfrdns Server

Welcome to the home stretch, my last [2] ITworld article on installing DJBDNS. I'll cover two things here. First, I'll show you how to 'import' your existing BIND zones into tinydns data format so you don't need to convert those files by hand. Lastly, I'll show you how to start up the axfrdns server, which will allow DNS secondaries running BIND to mirror your DNS zones.. . ..

Lastly, I'll show you how to start up the axfrdns server, which will allow DNS secondaries running BIND to mirror your DNS zones. At the beginning of this trip down DJBDNS lane, I tagged a challenge at the end of the message. Unlike my previous [1] challenge, this one had almost no response, probably because it was lost in obscurity at the bottom of the email. I'm re-issuing it again this week, and you'll find it at the end of this article. The link for this article located at IT World / Brian Hatch is no longer available. .

Microsoft: DNS Outsourcing to Linux After Service Outage

Last week Microsoft's Web server became unavailable to many users first through router misconfiguration and later through a denial of service attack. Networking experts blamed Microsoft's problems on a network domain which they said featured all four of its domain name server on the same network segment - creating a single point of failure. Following the debacle Microsoft has partially offloaded its DNS servers to Akamai Technologies - who tests suggest is running these servers on Linux. A number of Register readers have written to us pointing out that using nslookup, or other similar tools, its possible to see a number of servers in the akadns.com domain are listed as authoritative DNS servers for Microsoft's domains. Full details of which can be seen below. The link for this article located at TheRegister is no longer available. .
