IPsec Secure IP, or IPsec is a standard that provides authentication, verification, and encryption at the IP networking layer. This powerful technology has many uses, including virtual private networks(VPNs) which stretch across global networks. This paper will discuss the protocols and standards which apply to IPsec. It will present sample scenarios that utilize IP sec.

Cisco IPSec Overview IPSec provides IP network-layer encryption. The standards define several new packet formats: the authentication header (AH) to provide data integrity and the encapsulating security payload (ESP) to provide confidentiality and data integrity. Key management and security associations, the IPSec parameters between two devices, are negotiated with the Internet Key Exchange (IKE, formerly known as the Internet Security Association Key Management Protocol or ISAKMP/Oakley). IKE can use digital certificates for device authentication to enable the creation of large encryption networks. Without digital certificate support, IPSec solutions will not scale to the Internet. Cisco now offers IPSec in both the Cisco IOS software and the PIX Firewall. Cisco is also working with industry partners to ensure that IPSec is available on a wide range of systems, including Windows NT, Windows 95, and UNIX.

Linux IPsec Gateways Using FreeS/Wan Open source projects are now refined enough that they provide us with the most configurable and reliable solutions of a vast array of refined products. Recently I was told to implement a VPN solution for my company and keep costs down. Since my company is one of the 'survivors' of the dot-com world, this definitely means no highly expensive commercial products (those of us left have a budget.)

FOCUS on Linux: IPSec Fundamentals and Installation As the Internet grows, more and more emphasis is being placed on security. One especially hot topic in security these days is IPSec and IPv6. This article is going to explain what IP Security (IPSec) is, what it is good for, why should you use it and, finally, provide and example of how to deploy it on Linux.

Configuring IPsec/IKE on Solaris, Part 1 The IP Security Protocol (IPsec) and the Internet Key Exchange (IKE) protocol are designed to permit system and network administrators the capability to protect traffic between two systems. These systems can be network devices or individual hosts.

Configuring IPsec/IKE on Solaris Part 3 During the lab work for this article an annoying bug was discovered in the Solaris IPsec utilities. The configuration of ESP in the ipseckey utility is not possible in the default installation of Solaris.

Configuring IPSec and Ike on Solaris, Part 2 This article will discuss configuring IPsec to protect the traffic between two Solaris hosts. In this case, data confidentiality between the two hosts is not of concern however the integrity of the data is.
