But there's more to these pseudo timestamps than meets the eye. In fact, the number that you put in your file and the one that DNS extracts from it might be as different as 200907270001 and 3338774385. http://www.itworld.com/it-managementstrategy/72646/serial-numbers-zone-files-yours-and-nameds#comments IT management/strategy Network access control How-to DNS nslookup Sandra Henry-Stocker serial numbers zone files Mon, 27 Jul 2009 17:55:10 -0400 Sandra Henry-Stocker 72646 at http://www.itworld.com http://www.itworld.com/security/69366/neustar-offers-temporary-fix-kaminsky-bug NeuStar has developed a proprietary system for thwarting Web traffic hijacking attacks that the company plans to market until standard DNS Security (DNSSEC) mechanisms are deployed widely across the Internet. http://www.itworld.com/security/69366/neustar-offers-temporary-fix-kaminsky-bug#comments Security News DNS DNS cache poisoning DNSSEC Neustar Tue, 16 Jun 2009 14:12:19 -0400 ITworld staff 69366 at http://www.itworld.com http://www.itworld.com/security/68160/new-dns-bug-and-fix-announced Domain name registries are scrambling to patch a newly discovered bug in popular open source DNS software that could be exploited for denial-of-service attacks. http://www.itworld.com/security/68160/new-dns-bug-and-fix-announced#comments Security News DNS NSD patch Tue, 19 May 2009 20:44:58 -0400 ITworld staff 68160 at http://www.itworld.com http://www.itworld.com/security/65578/ultradns-service-knocked-offline-attack NeuStar confirmed that its UltraDNS managed DNS service was knocked offline for several hours Tuesday morning by a distributed denial of service attack. http://www.itworld.com/security/65578/ultradns-service-knocked-offline-attack#comments Security News DNS Neustar Wed, 01 Apr 2009 10:34:16 -0400 ITworld staff 65578 at http://www.itworld.com http://www.itworld.com/small-business/65202/use-opendns-protect-your-business-network If you aren't using OpenDNS to protect your small business network, now is the time to take the few minutes to set it up. http://www.itworld.com/small-business/65202/use-opendns-protect-your-business-network#comments Networking Security Small business Opinion DNS firewall OpenDNS Fri, 27 Mar 2009 09:41:11 -0400 ITworld staff 65202 at http://www.itworld.com http://www.itworld.com/security/63100/techies-end-run-feds-dns-security Forty years ago, when the U.S. government created the packet switching network that became the Internet, one of its goals was to create a robust network where traffic would be dynamically routed around blockages.
