Product Overview

Cisco IOS® SSL VPN is the first router-based solution offering Secure Sockets Layer (SSL) VPN remote-access connectivity integrated with industry-leading security and routing features on a converged data, voice, and wireless platform. SSL VPN is compelling; the security is transparent to the end user and easy for IT to administer.

With Cisco IOS SSL VPN, end users gain access securely from home or any Internet-enabled location such as wireless hotspots. Cisco IOS SSL VPN also enables companies to extend corporate network access to offshore partners and consultants, keeping corporate data protected all the while.

Cisco IOS SSL VPN in conjunction with the dynamically downloaded Cisco AnyConnect VPN Client provides remote users with full network access to virtually any corporate application. Cisco IOS SSL VPN features easy-to-use wizards that simplify deployment, and powerful tools to monitor and manage sessions in real time. Cisco IOS SSL VPN is a single-box VPN, security, and routing solution, unlike other vendor products that require multiple devices and management systems (Figure 1).

An integrated solution is easier to learn, deploy, provision, manage, and maintain, and has higher availability. This integrated solution has lower initial capital expenditure, lower deployment costs, and lower ongoing operational costs than competing multiple-device solutions.

Applications

Cisco IOS SSL VPN is useful for small and medium-sized businesses (SMBs) looking to extend remote access to employees and business partners. In addition, enterprises with a large number of small or medium-sized branches can use the Cisco IOS SSL VPN to combine remote access gateway capabilities with branch routers, thereby providing load-distribution functionality and redundancy to central-site VPN gateways. Figure 2 illustrates an application example for Cisco IOS SSL VPN.

Features and Benefits

Advanced full-network access: The Cisco IOS SSL VPN solution offers extensive application support through its dynamically downloaded AnyConnect VPN Client, enabling network-layer connectivity to virtually any application.

Ease of deployment and management: Intuitive, Web-based interface with wizards simplifies configuration. Advanced monitoring and management allow zero-touch remote endpoint management.

SSL VPN gateway network integration: Advanced authentication and access-control features pinpoint who gains access to what; virtualization allows efficient segmentation into departments, customers, or other groups of users.

Simple and cost-effective licensing: The simple licensing structure of Cisco IOS SSL VPN (no added licenses for special features), combined with the consolidated technology platform, provides customers with unparalleled cost savings and competitive per-user pricing.

Advanced Full-Network Access: Cisco AnyConnect VPN Client

With the Cisco AnyConnect VPN Client (Table 1), Cisco delivers a lightweight, centrally configured, easy-to-support SSL VPN tunneling client that allows access to virtually any application. The Cisco AnyConnect VPN Client can be loaded with any SSL-enabled browser and dynamically made available to the user in one of three methods: ActiveX, Java, or an .exe file.

Feature

Description and Benefit

Universal Application Access

This feature provides full client capabilities over SSL, including access to Cisco IP SoftPhone and voice-over-IP (VoIP) support, increasing remote-user productivity.

Ease of Download and Installation

Dynamic download and multiple delivery methods help ensure transparent download and distribution with Java, ActiveX, or .exe.
Small download size helps ensure rapid delivery.
No reboot is required after installation.

Increased Security

Client can be either removed at the end of a session or left permanently installed.

Zero-Touch Remote Administration

Central-site configuration provides integration, with no administration on the remote client side needed.

Ease of Deployment and Management

Cisco Configuration Professional(CCP) provides advanced wizards to make it easy to configure Cisco IOS SSL VPN.

Figure 3. Cisco Configuration Professional: Wizard-Based Management

Group-based management features allow administrators to design security policies and authentication methods for each group, a feature that is essential when extending network resources to non-corporate-managed users and endpoints.

In addition, Cisco IOS CLI can also be used to configure and monitor SSL VPN, for users who prefer that option.

For medium-sized or large installations, Cisco Security Manager Version 3.1 or later provides enterprise-class scalable SSL VPN configuration on Cisco routers and adaptive security appliances.

SSL VPN Gateway Network Integration

The Cisco IOS SSL VPN service running on Cisco routers allows the integration of SSL VPN with IP services on the router.

Table 3 lists the primary network integration capabilities.
