IP
Security (IPsec) Technology Primer
IPsec is a suite of protocols providing
security services for data communications
over public IP networks, and is an enabling
technology for widespread deployment of
Virtual Private Networks (VPNs). IPsec provides
data confidentiality, data authentication
and data integrity services between peering
devices - protecting IP traffic between
pairs of hosts, pairs of security gateways,
or between hosts and security gateways.
This paper describes the fundamental concepts
and processes used within the IPsec protocol
framework.

Validating
IPsec Network Security Devices
Manufacturers are developing IPsec-capable
routers and integrated security gateways
that combine IPsec VPN concentration with
network security and content switching features.
It is no longer adequate to test IPsec in
isolation; layer 4-7 capabilities must be
tested together with IPsec to fully stress
these devices in a realistic manner. In
this paper, we discuss the hottest IPsec
test issues and show you how to characterize
the performance of the latest security devices
using a mix of real application traffic
over IPsec tunnels. You will see some typical
test results and learn how to accurately
gauge performance from the perspective of
the end user’s experience.
