A Study on Network Performance from Selected Campus Environments - Jason Zurawski

See slides:https://spaces.internet2.edu/download/attachments/10402/20130423-zurawski-firewalls.pdf

Upcoming workshop:
Networking Issues for Life Sciences Research
 http://events.internet2.edu/2013/ftw-life-sciences/index.cfm
July 17- 18, 2013
Lawrence Berkeley National Laboratory
Need networking people and life sciences people to attend

Firewalls or "When Security and Performance Clash"
-Firewall is a useful tool, but can cause bottlenecks
-Delivers functionality that often can be implemented in different ways:
    - Filtering ranges can be implemented via ACLs
    - Port/Host blocking can be done on a host by host basis
     - IDS tools can implement near real-time blocking of ongoing attacks that match heuristics
Brown University example - Totally protected campus, with a border firewall
PSU example -  Unprotected campus, protection is the job of network customers

The Science DMZ
-It's a blueprint, not a specific design
-Approach to network architecture that preserves the ability to securely manage two different worlds (enterprise and research worlds)
