- DNSChanger Diagnostic
- "DNSChanger is a class of malicious software (malware) that changes a user's Domain Name System (DNS) settings, enabling criminals to direct unsuspecting internet users to fraudulent websites and otherwise interfere with access to internet services. It has been associated with 'click fraud', the installation of additional malware and other malicious activities. In November 2011, the FBI closed down a ring of cyber-criminals believed to be responsible for the worldwide spread of DNSChanger. An estimated four million users were affected worldwide. To avoid these victims losing access to internet services, the FBI worked with the Internet Systems Consortium (ISC) to set up and operate a temporary but correct DNS solution, while giving ISPs the opportunity to assist their customers to remove their potential infection. This temporary solution was switched off at 2pm AEST on 9 July 2012. In most cases, if you have managed to load this webpage after this date, you are very unlikely to be affected by DNSChanger, as you would have been unable to load the webpage if you were affected. However, there are some potential circumstances in which you may be still affected by DNSChanger, as described below... This DNSChanger Diagnositic is a joint Australian Government initiative between: - Australian Communications and Media Authority - CERT Australia - Stay Smart Online "

- Secure Domain Name System (DNS) Deployment Guide - in pdf format (897kb)
- (This document requires the use of Adobe Acrobat Reader). Recommendations of the National Institute of Standards and Technology, by Ramaswamy Chandramouli and Scott Rose. Special Publication 800-81r1, Sponsored by the Department of Homeland Security. National Institute of Standards and Technology, April 2010. "... This document provides deployment guidelines for securing DNS within an enterprise. Because DNS data is meant to be public, preserving the confidentiality of DNS data pertaining to publicly accessible IT resources is not a concern. The primary security goals for DNS are data integrity and source authentication, which are needed to ensure the authenticity of domain name information and maintain the integrity of domain name information in transit. This document provides extensive guidance on maintaining data integrity and performing source authentication. Availability of DNS services and data is also very important; DNS components are often subjected to denial-of-service attacks intended to disrupt access to the resources whose domain names are handled by the attacked DNS components. This document presents guidelines for configuring DNS deployments to prevent many denial-of-service attacks that exploit vulnerabilities in various DNS components..."

- DNSSEC is But One Link in the Security Chain
- By Chris Wright. CircleID, July 14, 2010. "As the implementation of DNSSEC continues to gather momentum and with a number of ccTLDs, and the .org gTLD having deployed it into their production systems, I think it is worth pausing to take a look at the entire DNSSEC situation. Whilst it is absolutely clear that DNSSEC is a significant step forward in terms of securing the DNS, it is but one link in the security chain and is therefore not, in itself, a comprehensive solution to fully securing the DNS system..."

- Domain Moving Day the Key Relevance Way
- by Mike Churchill. SEMClubHouse, October 17, 2008. "So, you're gonna change hosting providers. In many cases, moving the content of the site is as easy as zipping up the content and unzipping it on the new server. There is another aspect of moving the domain that many people over look: DNS. The Domain Name System (DNS) is the translation service that converts your domain name (e.g. keyrelevance.com) to the corresponding IP address. When you move hosting companies, it's like changing houses, if you don't set up the Change of Address information correctly, you might have some visitors going to the old address for a while. Proper handling of the changes to DNS records makes this transition time as short as possible..."
