Enhanced Security
• Dynamicfirewall—Companiesincreasinglyrely on internal networks and serversforaccessingcompany data. To
take advantage of the Internet as a key business tool, companies must connect their internal networks to the
Internet while keeping sensitive internal data secure. Company data can be protected against unauthorized access
with stateful firewalls. The integrated Cisco IOS Firewall Feature Set is a stateful firewall that provides:
– Stateful (dynamic) ACLs (application/context based)
– Java blocking
– Denial-of-service attack detection and prevention
– Real-time alerts and audit trails
Dynamic firewalls provide these vital enhanced security features. The term firewall is used by many vendors but
not uniformly referred to as stateful firewalls. Firewalls that are not dynamic do not provide these enhanced
security features.
Encryption and Tunneling
The Cisco 800 Series routers provide IPSec encryption technology to enable small offices and telecommuters to
deploy VPNs. IPSec encryptionprovides privacy, integrity, and authenticityfor transmission of sensitive information
over the Internet. The unique end-to-end Cisco offering allows customers to implement IPSec encryption
transparently into the network without affecting individual PCs. The Cisco 800 Series with IPSec encryption allows
significant cost savings by using the Internet to create secure connections between small offices and teleworkers. As
a component of the Cisco VPN solution, the Cisco 800 Series supports:
• IPSec tunneling with 128- or 56-bit Digital Encryption Standard (DES) or Triple DES (3DES)
• Layer 2 Tunneling Protocol (L2TP)
• Generic routing encapsulation (GRE)
Manageability
Cisco 800 Series routers support management by a wide range of platforms and applications. Cisco ConfigMaker,
Cisco Fast Step Software (Windows 95, 98, and NT 4.0), and CiscoView (UNIX) applications provide superior
capabilities for configuration and security management, aswell asperformance andfault monitoring.The Cisco800
Series supports centralized administration and management via Simple Network Management Protocol (SNMP),
Telnet, or local management through the router console port.
Safe Investment
Small offices with limited time, money, and staff need to know their technology investments are safe.
Field-expandable dynamic RAM(DRAM)andFlashmemory allow small offices to take advantage of new Cisco IOS
feature enhancements. And because the Cisco 800 Series incorporates an advanced processor and memory
architecture, it can support future applications as customer networking needs expand.
