IPAM

During my recent webinar of October 25th regarding IPv6 and internationalized domain names (IDNs), I promised to post a few links on my blog regarding security considerations when deploying IDNA. These security concerns stem primarily from homographs, where characters are visually identical but have in fact different unicode and therefore IDN representations. The issue that may arise is that a link may appear "legitimate" or intended by a user but the IDNA-translated URL may result in a DNS lookup mapping to an attacker's DNS zone file which could result in phishing and similar attacks. This of course is not an issue unique to IDNA as it occurs on a daily basis within the Latin alphabetic representation in DNS. Attackers publish links that substitute "1" for "l" or "0" for "O", etc. or outright misspell otherwise familiar words or company names. But IDNA adds an additional layer of obscurity as homographs will be indistinguishable...

Beginning next week, I'll be conducting a series of five webinars with the help of gotomeeting, focused on IPv6. Actually the first webinar in the series touches on IPv6 though it focuses primarily on IDNs, internationalized domain names. I decided to offer this IDN/IPv6 webinar as the first in the series since it introduces IPv6 and provides a context for IPv6 especially for IT managers in North America, namely to facilitate continued web presence for Asia users. IDN is another evolving IPAM-related technology that can ease the usability or navigation to your sites for Asia-based users among others. Following are the planned dates and topics for the IPv6 webinar series: Webinar Topic Date and Time IDNs and IPv6: Enhancing your Asia presence Tuesday, October 25, 2011, 12-1pm EDT Introduction to IPv6 Thursday, October 27, 2011, 12-1pm EDT IPv6 deployment checklist Tuesday, November 1, 2011, 12-1pm EDT Configuring DNS for a dual stack network Thursday, November 3, 2011, 12-1...
