Security by Obscurity?

Ah yes, 'Security by obscurity': "Many people believe that 'security through obscurity' is flawed because... secrets are hard to keep." I'm glad the guys guarding the A Root Servers are up on the latest security trends. Of course, you could hide the A Root Servers at the heart of the Minotaur's maze, but they're still going to be "right over there" in cyberspace, at 198.41.0.29 more

DNS Gets A Formal Coordination System

CircleID recently interview Paul Vixie, Founder & Chairman of Internet Software Consortium (ISC), to discuss ISC's newly formed Operations, Analysis, and Research Center (OARC). OARC is launched in response to DDoS attacks at the Internet's core infrastructure and the vital requirement for a formal coordination system. OARC is also a part of US homeland security initiatives, such as the formation of Information Sharing and Analysis Centers (ISACs).

"Registries and registrars, ccTLD operators, large corporate NOCs, ISPs and ecommerce companies that host many domain names are all likely candidates. This is also a natural for law enforcement groups that are worried about attacks on the Internet." more

Blacklists Down from Fear of DDoS

Yet another DNS blacklist has been taken down out of fear of the DDoS attacks that took down Osirusoft, Monkeys.com, and the OpenRBL. Blackholes.compu.net suffered a Joe-Job (A Joe-Job is essentially spam designed to look like it's coming from someone else.) earlier this week. Apparently the Joe-Jobing was enough to convince some extremely ignorant mail administrators that Compu.net is spamming and blocked mail from compu.net. Compu.net has also seen the effects of DDoS attacks on other DNS blacklist maintainers. They've decided that the risk to their actual business is too great and they are pulling the plug on their DNS blacklist before they come under the gun by spammers. more

Preventing Future Attacks: Alternatives In DNS Security Management - Part II

In Part I of this article I set the stage for our discussion and overviewed the October 21st DDoS attacks on the Internet's 13 root name servers. In particular, I highlighted that the attacks were different this time, both in size and scope, because the root servers were attacked at the same time. I also highlighted some of the problems associated with the Domain Name System and the vulnerabilities inherent in BIND. Part II of this article takes our discussion to another level by critically looking at alternatives and best practices that can help solve the security problems we've raised. more

Preventing Future Attacks: Alternatives In DNS Security Management - Part I

The October 21 DDoS attacks against the 13 root-name servers containing the master domain list for the Internet's Domain Name System (DNS), (which reportedly took offline 9 of the 13 servers) remain a clear and daunting reminder of the vulnerabilities associated with online security. Many DNS authorities have named the most recent hit the largest DDoS attack against the root server system. Chris Morrow, network security engineer for UUNET, the service provider for two of the world's 13 root servers, recently told The Washington Post... more
