* Stateful inspection
. Some firewalls also employ an inspection module, which is software that inspects packets and can verify the application, user, and transportation method.
The client has comprehensive security functions, including IPSec encryption with AES or 3-DES; authentication via digital certificates and hardware tokens; a dynamic personal firewall with stateful inspection
and friendly net detection for automatic detection of secure and non-secure networks.
* Performance: Increases of 10 to 20 percent in the amount of content passing through the appliance for stateful inspection
saves companies from having to purchase additional appliances when more bandwidth is required.
These capabilities are typically a subset of features found in products like enterprise firewalls and packet shapers, usually employing a combination of MAC, protocol and transport layer rules, but seldom providing stateful inspection
or application layer capabilities.
It does, however, come closer to resembling some of the popular personal firewall products on the market today, by giving some level of control over outbound application traffic, unlike ICF, which was a basic stateful inspection
FireWall-1 GX is based on Check Point's Stateful Inspection
technology and Secure Virtual Network architecture.
In addition, the new firewall offering utilizes a uniquely engineered feature called Firewall Flows, which moves the Stateful Inspection
process to the hardware level, significantly reducing the CPU needs of the firewall for increased performance.
is a low-cost residential Internet security firewall based on Check Point Software's powerful Stateful Inspection
The devices offer features such as stateful inspection
firewall, IPSec VPN, standards-based routing/switching protocols, CLI, web-based GUI, QoS for VoIP and other applications and NAT-compatible SIP ALG for VoIP applications.
The resulting D-Link NetDefend security appliances will offer SMBs an all-in-one network security solution combining an enterprise-class stateful inspection
firewall, gateway antivirus, intrusion prevention, remote-access virtual private networking, and content filtering into a single, easy-to-use platform.
