Feature		Description
VPNs, IPSec encryption, and QoS		Operates with Cisco IOS software encryption, tunneling, and QoS
support		features to secure VPNs.
		Provides scalable, encrypted tunnels on the router while
		integrating strong perimeter security, advanced bandwidth
		management, intrusion detection, and service-level validation.
		Standards based for interoperability: Supports Internet Protocol
		Security (IPSec) encryption standards with both 56-bit Data
		Encryption Standards (DES) and 168-bit Triple DES (3DES);
		generic routing encapsulation (GRE); Layer 2 forwarding (L2F);
		Layer 2 tunneling protocol (L2TP).
Real-time alerts		Logs alerts for denial-of-service attacks or other preconfigured
		conditions; configurable on a per-application, per-feature basis.
Audit trail		Details transactions; records time stamp, source host, destination
		host, ports, duration, and total number of bytes transmitted for
		detailed reporting; configurable on a per-application, per-feature
		basis.
Event logging		Allows administrators to track potential security breaches or
		other nonstandard activities in real time by logging system error
		message output to a console terminal or syslog server, setting
		severity levels, and recording other parameters.
Firewall management		Wizard-based network configuration tool offers step-by-step
		guidance through network design, addressing, and Cisco IOS
		Firewall security policy configurations.
Integration with Cisco IOS		Interoperates with Cisco IOS features, integrating security policy
software		enforcement into the network.
Basic and advanced traffic filtering		Standard and extended access control lists (ACLs) let you apply
		access controls to specific network segments and define the traffic
		permitted to pass through a network segment.
Policy-based multi-interface		Can control user access by IP address and interface as determined
support		by the security policy.
Redundancy/failover		Automatically routes traffic to a backup router if a failure occurs.
Network address translation		Hides internal network from the outside for enhanced security.
