Figure 1. Customizable VPN Services for Any Deployment Scenario
Cisco ASA 5500 Series SSL/IPsec VPN Edition
This edition offers flexible VPN technologies for any connectivity scenario, with scalability up to 10,000 concurrent users per device. It provides easy-to-manage, full-tunnel network access through:
• SSL (DTLS and TLS)
• IPsec VPN client technologies
• Cisco AnyConnect Secure Mobility Solution optimized for Cisco Web Security
• Advanced clientless SSL VPN capabilities
• Network-aware site-to-site VPN connectivity
This supports highly secure connections across public networks to mobile users, remote sites, contractors, and business partners. Costs associated with VPN deployment and operations are reduced by eliminating ancillary equipment required to scale and secure a VPN.
Benefits of a Cisco AnyConnect Secure Mobility Solution include:
• SSL (TLS & DTLS), and IPsec-based full network access: Full network access provides network-layer remote- user connectivity to virtually any application or network resource, and is often used to extend access to managed computers, such as company-owned laptops. Connectivity is available through the automatically downloaded Cisco AnyConnect Secure Mobility Client, the Microsoft Layer 2 Tunneling Protocol (L2TP)/IPsec VPN client, and the Apple iPhone/Mac OS X 10.6+ IPsec VPN clients.
The Cisco AnyConnect Secure Mobility Client will automatically adapt its tunneling protocol to the most efficient method based on network constraints, and is the first VPN product to use the DTLS protocol to provide an optimized connection for latency-sensitive traffic, such as voice-over-IP (VoIP) traffic or TCP-based application access. By supporting SSL (TLS & DTLS), and IPsec-based remote-access VPN technologies, the Cisco ASA 5500 Series delivers unsurpassed flexibility to meet the needs of the most diverse deployment scenarios.
• Superior clientless network access: Using the ubiquity of SSL encryption available in Internet browsers, the AnyConnect Secure Mobility Solution delivers clientless remote access. This provides access to network applications and resources, regardless of location, without the need for desktop VPN client software.
The solution delivers clientless access to any web-based application or resource, terminal services applications such as Citrix, and optimized Microsoft Outlook Web Access and Lotus iNotes. It also provides access to common thick-client applications such as email, calendar, instant messaging, FTP, Telnet, and SSH applications. Additionally, the superior content rewriting capabilities of the Cisco ASA 5500 Series help ensure reliable rendering of complex webpages with Java, JavaScript, ActiveX, Flash, and other sophisticated content.
• Cisco AnyConnect Secure Mobility Solution: Enforces security policy in every transaction independent of where the user is located, whether it is an enterprise, in-house owned or a SaaS application. Secure Mobility allows the administrator to require always-on secure network connectivity with a policy to permit or deny network connectivity if access is unavailable. These services are optimized for use with Cisco Web Security, and require an AnyConnect Premium license or a Secure Mobility license.
• Network-aware site-to-site VPNs: Highly secure, high-speed communications are possible between multiple office locations. Support for quality of service (QoS) and routing across the VPN helps ensure reliable, business-quality delivery of latency-sensitive applications, such as voice, video, and terminal services.
• Threat-protected remote access VPNs: VPNs are a primary source of malware infiltration into networks. Malware includes worms, viruses, spyware, keyloggers, Trojan horses, and rootkits. In the Cisco ASA 5500 Series, the depth and breadth of intrusion prevention, antivirus, application-aware firewall, and VPN endpoint security capabilities minimizes the risk that a VPN connection will become a conduit for security threats.
• Cost-effective VPN deployment and operations: Scaling and securing VPNs often requires additional load balancing and security equipment, which increases both equipment and operational costs. The Cisco ASA 5500 Series integrates these functions, delivering an unprecedented level of network and security integration among the VPN products available today. By offering support for flexible tunneling options on a single platform, the Cisco ASA 5500 Series provides customers with cost-effective alternatives to deploying parallel VPN infrastructures.
• Scalability and resiliency - The Cisco ASA 5500 Series can support up to 10,000 simultaneous user sessions per device, with the ability to scale to tens of thousands of simultaneous user sessions through integrated clustering and load-balancing capabilities. Stateful failover features deliver high-availability services for unsurpassed uptime.

Threat-Protected VPN Features
The Cisco ASA 5500 Series SSL/IPsec VPN Edition provides advanced security for VPN deployments through its integrated network and endpoint security technologies. Securing the VPN is necessary to prevent network attacks, such as worms, viruses, spyware, keyloggers, Trojan horses, rootkits, and hacking. Detailed application and access control policy helps ensure that individuals and groups of users have access only to the applications and network services to which they are entitled (Figure 2).
Figure 2. Threat-Protected VPN Services Use Onboard Security to Protect Against VPN Threats
Network Security at the VPN Gateway
Worms, viruses, application-embedded attacks, and application abuse are among the greatest security challenges in today's networks. Remote access and remote-office VPN connectivity are common points of entry for such threats, due to limited security capabilities on VPN devices. VPNs are often deployed without proper inspection and threat mitigation applied at the tunnel termination point at the headquarters location, which allows malware from remote offices or users to infiltrate the network and spread.
With the converged threat mitigation capabilities of the Cisco ASA 5500 Series, customers can detect malware and stop it before it enters the network interior. For application-embedded attacks, such as spyware or adware spread through file-sharing in peer-to-peer networks, the Cisco ASA 5500 Series deeply examines application traffic. The solution identifies a dangerous payload and drops its contents before it reaches its target and causes damage.
Table 5 lists some VPN gateway security features provided by the Cisco ASA 5500 Series.
Table 5. Network Security at the Cisco ASA 5500 Series VPN Gateway
Feature
Description

Worms, viruses, spyware, keyloggers, Trojan horses, and rootkits are thwarted at the Cisco ASA 5500 Series VPN gateway, thereby eliminating threats before they spread throughout the network.
Application-Aware Firewall and Access Control
Application-aware traffic inspection supports thorough user access control and helps prevent abuse of unwanted applications, such as peer-to-peer file sharing across the VPN connection.
Intrusion Prevention
The Cisco ASA 5500 Series guards against a multitude of network exploits.
Access Restrictions
The permission or denial of access to confidential resources is based on flexible configuration policies and current posture status.
Virtual LAN (VLAN) Mapping
Enforcement of user- and group-based traffic access restrictions are based on a configured VLAN.
Comprehensive Endpoint Security for SSL VPN
SSL VPN deployments allow universal access from both highly secure and non-corporate-managed endpoints, and provide the ability to extend network resources to diverse user communities. Users can access the network from a corporate-managed PC, personal network-accessible device, public terminal, or other device. With this extension of the network, the points for potential network security attacks also increase.
Cisco Secure Desktop minimizes data such as cookies, browser history, temporary files, and downloaded content left behind after an SSL VPN session terminates. Endpoint posture checking for full network access users is also available through integration with the Cisco NAC Appliance and Cisco NAC Framework. Table 6 highlights Cisco Secure Desktop features. (Premium License required).
