IPsec Overview
A secure network starts with a strong security policy that defines the freedom of access to
information and dictates the deployment of security in the network. Cisco Systems offers many
technology solutions for building a custom security solution for Internet, extranet, intranet, and
remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide
network security. Cisco System’s IPsec delivers a key technology component for providing a total
security solution. Cisco’s IPsec offering provides privacy, integrity, and authenticity for transmitting
sensitive information over the Internet.
Cisco’s end-to-end offering allows customers to implement IPsec transparently into the network
infrastructure without affecting individual workstations or PCs. Cisco IPsec technology is available
across the entire range of computing infrastructurE. Windows 95, Windows NT 4.0, and Cisco IOS
software.
IPsec is a framework of open standards for ensuring secure private communications over the
Internet. Based on standards developed by the Internet Engineering Task Force (IETF), IPsec ensures
confidentiality, integrity, and authenticity of data communications across a public network. IPsec
provides a necessary component of a standards-based, flexible solution for deploying a networkwide security policy.
