Secure Networking Features and Benefits
The Cisco 1800 Series features a built-in hardware-accelerated encryption on the motherboard that can be enabled
with an optional Cisco IOS Software security image. The onboard hardware-based encryption acceleration offloads
the encryption processes to provide greater IPSec 3DES and AES throughput. With the integration of optional VPN
AIMs, NAC for antivirus defense, and Cisco IOS Software-based firewall and IPS support, Cisco offers the industry’s
leading robust and adaptable security solution for small to medium-sized businesses and small enterprise branch
offices. Table 3 outlines router-integrated security features and benefits.
Table 3. Features and Benefits of Secure Networking
Feature Benefit
Hardware-Based Encryption
on Motherboard
Support for hardware-based encryption on the Cisco 1841 can be enabled through an optional Cisco IOS
Software security image.
AIM-Based VPN Acceleration
Support for an optional dedicated VPN AIM can deliver two to three times the performance of embedded
encryption capabilities.
SSL Web VPN
Allows businesses to securely and transparently extend their networks to any Internet-enabled location using
SSL VPN; the Cisco IOS WebVPN supports clientless access to applications such as HTML-based intranet
content, e-mail, network file shares, and Citrix and to the Cisco SSL VPN Client, enabling full network access
remotely to virtually any application
AIM-Based SSL VPN
An optional dedicated SSL VPN AIM module provides SSL VPN acceleration and supports two times the
number of tunnels when compared to embedded IOS based SSL VPN capabilities. The SSL VPN AIM module
also supports IPSEC VPN and IP Payload Compression Protocol in hardware.
NAC
NAC allows network access only to compliant and trusted endpoint devices for antivirus defense.
IPS Support
Flexible support is provided with Cisco IOS Software.
New intrusion-detection-system (IDS) signatures can be dynamically loaded independent of the Cisco IOS
Software release.
Cisco Easy VPN Remote
and Server Support
This feature eases administration and management of point-to-point VPNs by actively pushing new security
policies from a single headend to remote sites.
Dynamic Multipoint VPN
(DMVPN)
DMVPN is a Cisco IOS Software solution for building IPSec + generic routing encapsulation (GRE) VPNs in an
easy and scalable manner.
Group Encrypted Transport
(GET) VPN
GET VPN is a Cisco IOS Software solution that simplifies securing large Layer 2 or MPLS networks requiring
partial or full-mesh connectivity by providing tunnel-less VPN connectivity
Cisco IOS Firewall, Including
URL Filtering
URL filtering support is available with optional Cisco IOS Security Software.
Real-Time Clock Support
Real-time clock support keeps an accurate value of date and time for applications that require an accurate time
stamp-such as logging, debugging, and digital certificates.
Cisco Security Device
Manager
An intuitive, easy-to-use, Web-based device management tool embedded within the Cisco IOS Software access
routers can be accessed remotely for faster and easier deployment of Cisco routers for both WAN access and
security features.
Cisco SDM helps resellers and customers to quickly and easily deploy, configure, and monitor a Cisco access
router without requiring knowledge of the Cisco IOS Software command-line interface.
USB Port (1.1)
The integrated USB port is configurable with an optional USB token for secure configuration distribution and off-
platform storage of VPN credentials.
