At this month's PLUG Security meeting:
Donald McCarthy: passiveDNS For fun and Profit (part1)

For more information:
http://phxlinux.org/index.php/meetings/20-plug-security.html

Description:
If you DNS infrastructure has a bad day, your network has a bad day. If your DNS infrastructure has a good day, something else is bound to go wrong. PassiveDNS generally wont help you fix either.

PassiveDNS is a historical look at observed DNS queries over time. It is akin to The Internet Archive's Way Back Machine, but for DNS zones. Its utility as an operations and security tool is valuable and not easily replaced by another type of data.

In this presentation we will cover exactly what passiveDNS is and isn't, passiveDNS architecture, some security use cases, and if time allows some live demonstration.

In part 2 of the presentation (another month) I will demonstrate some passiveDNS tooling and more in depth practical knowledge to turn theoretical use cases into automated assistance for a SOC or NOC.
