Cisco IOS IPsec functionality provides network data encryption at the IP packet level, offering a robust, standards-based, security solution. IPsec provides data authentication and anti-replay services, in addition to data confidentiality services. It is the only way to implement secure VPNs. Cisco Easy VPN greatly simplifies virtual private network (VPN) deployment for remote offices and teleworkers. Based on the Cisco Unified Client Framework, the Cisco Easy VPN solution centralizes VPN management across all Cisco VPN devices, thus reducing the management complexity of VPN deployments. Cisco Easy VPN solution helps enable an integration of VPN remote devices--such as Cisco routers, Cisco PIX Security Appliances, the Cisco VPN 3002 Hardware Client, or the Cisco VPN Client--within a single deployment and with a consistent policy and key management method, which simplifies remote side administration. Cisco Easy VPN consists of two components: Cisco Easy VPN Remote and Cisco Easy VPN Server. The Cisco Easy VPN Remote feature allows Cisco IOS routers, Cisco PIX Security Appliances, Cisco VPN 3002 Hardware Clients and the Cisco VPN Client to receive security policies upon a VPN tunnel connection from a Cisco Easy VPN Server, minimizing configuration requirements at the remote location. This cost-effective solution is ideal for remote offices with little IT support or for large customer premises equipment (CPE) deployments where it is impractical to individually configure multiple remote devices. This feature makes VPN configuration as easy as entering a password, which minimizes local IT support, increases productivity, and lowers costs. The Cisco Easy VPN Server allows Cisco IOS routers, Cisco PIX Security Appliances, and Cisco VPN 3000 Concentrators to act as VPN head-end devices in site-to-site or remote-access VPNs, where the remote office devices are using the Cisco Easy VPN Remote feature. This feature pushes security policies defined at the central site to the remote VPN device, helping to ensure that those connections have up-to-date policies in place before the connection is established. Additionally, a device enabled with the Cisco Easy VPN Server can terminate VPN tunnels initiated by mobile remote workers running the Cisco VPN Client software on PCs. This flexibility allows mobile and remote workers to access critical data and applications on their corporate intranet. Cisco Easy VPN Remote is now available on Cisco 800, 1700, and UBR900 Series routers, Cisco PIX 501 and 506E Security Appliances, and Cisco VPN 3002 Hardware Clients. The Cisco Easy VPN Server is available on numerous Cisco VPN routers including the Cisco 1700, 7200 Series routers with Cisco IOS release 12.2(8)T, Cisco PIX Security Appliances, and all Cisco VPN 3000 Concentrators.
