The Cisco IOS Firewall feature set integrates robust firewall functionality and intrusion detection for each network perimeter, enriching Cisco IOS security features. The Cisco IOS Firewall feature set provides a comprehensive, integrated, virtual private network (VPN) solution, if combined with Cisco IOS IPSec software and other Cisco IOS software technologies, such as L2TP tunneling and quality of service [QoS]. Cisco IOS software is available on a wide range of Cisco router platforms, allowing customers to choose router platforms based on bandwidth, Lan/wan density, and multiple service requirements, while benefiting from advanced security.

While people seek to take advantage of the Internet's unmatched performance, they need secure solutions to:

Protect the internal network and prevent hackers from invading.

Provides secure Internet and remote access connections.

Start the network trade through the World Wide Web.

Today, the Internet has become a powerful new technology focus that has greatly enhanced communication between businesses and customers, suppliers, agent products, and remote employees. Users must be convinced that the network business, especially the business on the public network, is secure. Cisco iOS software runs on more than 80% of the Internet backbone routers. Cisco iOS software provides comprehensive network services and launches networked applications. Cisco iOS security services provide secure solutions to the Internet, intranet, and remote access network, providing End-to-end network security. A key part of the entire security solution is the network firewall, which monitors traffic across the perimeter of the network and restricts it against security policies. Perimeter routers are visible across any network boundary, such as between a private network, an intranet, an external network, or the Internet. Firewalls separate internal (private) and external (public) networks. Cisco IOS Firewall feature set is listed as an option for Cisco IOS software, offering an advanced security solution to protect the network against security breaches. This integrated router security solution provides a part of the Cisco Systems Security solution System.

The Cisco IOS Firewall feature set is one of three Cisco Firewall solutions designed to meet the different firewall requirements within a network, whether it is a dedicated device (PIX firewall), an NT based solution (Centri Firewall), or an integrated network infrastructure ( Cisco iOS firewall feature set). The Cisco Firewall family has a comprehensive security feature that meets the requirements of boundary policy strengthening, extended to more complex virtual private networks (VPNs), content filtering, and service rejection (denial of services) detection and prevention. With deployment, Cisco firewalls allow network administrators to implement a more powerful security architecture by implementing a tiered security policy. No other network vendor can provide such flexibility in its security solution. The Cisco IOS Firewall feature set enhances Cisco's End-to-end security offerings by providing access to directory policies within the network infrastructure itself, enabling the flexibility and control that independent devices cannot provide.
