Next Generation Firewalls
Next generation firewalls aim to provide integrated threat protection through consolidation of gateway functions in virtual appliances with enterprise-class features for all segments. They aim to keep up with evolving intelligence-based threats by providing end-to-end policy compliance across all devices, including mobile, and virtualization capabilities for multi-tenant environments. Firewalls have evolved over 25 years from basic packet filtering to deep packet inspection to address more sophisticated threats that can bypass policies by posing as legitimate traffic.

Can you keepup? • Intelligence • Consolidation of gateway functions » Reduce emphasis on human » Simplification intervention • Enterprise-class features available for all • End-to-end protection segments » Policy compliance for all » Not limited to large appliances devices, including mobile • Growth of WLANs • Virtualization » Mobile enterprise » Virtual appliances » Multi-tenant environments
- 3. Firewalls Evolution • Firewalls developed over 25 years ago » Initial protection by blocking traffic by port, protocol, or IP address • From packet filtering to circuit level to proxy to deep packet inspection… • Threat landscape evolved from primitive to more sophisticated » Able to pose as legitimate traffic & bypass policies » Business processes evolved as well • Firewall policies disabled over time to allow critical applications to pass through

Editor's Notes
- #5 Here is an example of our approach in action. This is the Koobface attack, which is still active in the wild.Starts as a link to a non-existent video on a malicious site sent via IM, email, or webmail. The first layer of protection is web filtering to block access to the site. If the user clicks on the link, he would receive a phony alert telling him his player is not working, and to download a non-existent new version on a malicious site. By clicking on the “OK” button on the phony Error message, the user is actually instructing his system to install the virus. Antivirus protection would detect the file that the user is trying to install, and block itOnce installed, the worm would try to propagate. The IPS technology would detect the propagation effort, and block it before it could succeed.
