Abstract
SmartDefense is a key component of virtual private network (VPN)-1/Firewall-l. Although the fundamental aspect of any firewall is to permit or deny traffic based on a set of rules, today's world of more sophisticated applications brings the need for protection against attacks that cannot be prevented with a standard rule base. By combining an easy-to-use interface with powerful attack detection and notification, SmartDefense allows firewall administrators to extend the protection that VPN-1/Firewall-1 provides to the application layer. SmartDefense offers protection against numerous types of attacks, including hypertext transfer protocol (HTTP) worms, cross-site scripting, and vulnerabilities inherent to point-to-point applications. Because of the nature of the protection that SmartDefense provides, it would not be effective without frequent updates. New worms and exploits are constantly being developed so SmartDefense must adapt to offer continued protection. The SmartUpdate feature, along with a current subscription license, provides a painless and efficient way to keep SmartDefense current.
