There is only one week left to register to attend the next free ACM Webcast, “The Security Impact of IPv6,” presented on Wednesday, September 25, 2013 at 12 pm ET (11 am CT/10 am MT/9 am PT/4 pm GMT) by Dr. Johannes B. Ullrich, Dean of Research and a faculty member of the SANS Technology Institute. The talk will be followed by a live question and answer session moderated by Tom Limoncelli, an internationally recognized author, speaker, system administrator, and member of the ACM Case Study Committee. (If you’d like to attend but can’t make it to the virtual event, you still need to register to receive a recording of the webinar when it becomes available.)
