IP security (IPSec) is a framework of open standards for securing Layer 3 IP communications by encrypting and authenticating all IP packets. You can use IPSec to protect one or more paths between a pair of hosts, between a pair of security gateways (such as J-series Services Routers), or between a Services Router security gateway and a host.
You can use either J-Web Quick Configuration or a configuration editor to configure IPSec.
This chapter contains the following topics. For more information about IPSec, see the JUNOS System Basics Configuration Guide and the JUNOS Services Interfaces Configuration Guide.
