July 2009 DDoS thoughts

by d.strom, cissp, gsec, gsna on July 8, 2009

Reports are coming out this morning of distributed denial of service attacks coming from North Korea and targeting South Korean government and business web sites. I heard one report which stated that US government sites are also being targeted.

I’ve never really thought USA Today was a bastion of InfoSec news, but they have a report here that gives a basic understanding of what is going on.

It is evident that the information is not complete. Unnamed sources that are “not authorized” to speak are providing sanitized information.

I would expect there to be more information coming out a little at a time.

UPDATE: Information is starting to come out http://www.google.com/hostednews/ap/article/ALeqM5icTKBW9_fm-oKDzns75BI-ykokSwD999UN580.

My plan is to use this as an opportunity and reminder to revisit our plans and procedures in the event any of our computers are a part of a botnet, or in the event our organization becomes a target.

Steps I plan to take specifically for this threat:

  • Work with ISP to make sure that they are filtering DDoS at their routers for traffic that is headed our way.
  • Verify that all of our computers have current antivirus running and that signatures are current.
  • Force an AV scan on all workstations.
  • Force an AV scan on all servers using a secondary AV engine.
  • Monitor in-bound traffic closely and pay attention to alerts.
  • Notify Management of the situation if anything begins to develop.

Sleep tight, y’all.
