Integrated Network Security for Data and Mobility

Security is essential to protect a business' intellectual property while also ensuring business continuity and

providing the ability to extend the corporate workplace to employees who need anytime, anywhere access to

company resources. As part of the architectural framework of the SAFE Blueprint from Cisco that allows

organizations to identify, prevent, and adapt to network security threats, the Cisco 1900 Series ISRs facilitate

secure business transactions and collaboration.

The Cisco IOS Software Security technology package license for the Cisco 1900 Series offers a wide array of

common security features such as advanced application inspection and control, threat protection, and encryption

architectures for enabling more scalable and manageable VPN networks in one solution set. The Cisco 1921

offers native hardware-based encryption acceleration to provide greater IPsec throughput with less overhead for

the router processor when compared with software-based encryption solutions. Cisco ISRs offer a comprehensive

and adaptable security solution for branch-office routers that include features such as:

Secure connectivity: Achieve secure collaborative communications with Group Encrypted Transport VPN,

●

Dynamic Multipoint VPN (DMVPN), or Enhanced Easy VPN.

Integrated threat control: Respond to sophisticated network attacks and threats using Cisco IOS Firewall,

●

Cisco IOS Zone-Based Firewall, Cisco IOS IPS, and Cisco ScanSafe Web Security and Flexible Packet

Matching (FPM).

Identity management: Intelligently protect endpoints using technologies such as authentication,

●

authorization, and accounting (AAA) and public key infrastructure (PKI).

Mobility Services

Wireless WAN

Cisco 3G wireless WAN (WWAN) modules combine traditional enterprise router functions such as remote

management, advanced IP services such as voice over IP (VoIP), and security, with mobility capabilities of 3G

WAN access. Using high-speed 3G wireless networks, routers can replace or complement existing landline

infrastructure such as dialup, Frame Relay, and ISDN. Cisco 3G solutions support 3G standards High-Speed

Packet Access (HSPA+) and Evolution Data Only/Evolution Data Optimized (EVDO), offering you a true multipath

WAN backup and the ability to rapidly deploy primary WAN connectivity. For more information about 3G solutions

on Cisco ISRs, please visit http://www.cisco.com/go/3g.

Integrated LAN Switching

The Cisco 1921 Integrated Services Router will support the EHWIC LAN modules when they become available in

the future. The Cisco 1921 supports the existing singlewide Cisco EtherSwitch

D modules, which greatly expand the capabilities of the router by integrating industry-leading Layer 2 switching.

Managing Your Integrated Services Routers

Network management applications are instrumental in lowering operating expenditures (OpEx) while improving

network availability by simplifying and automating many of the day-to-day tasks associated with managing an end-

to-end network. "Day-one device support" provides immediate manageability support for the ISR, enabling quick

and easy deployment, monitoring, and troubleshooting from Cisco and third-party applications.
