Understanding Policies
In Security Manager, a policy is a set of rules or parameters that define a particular aspect of network
configuration. You configure your network by defining policies on devices (which includes individual
devices, service modules, security contexts, and virtual sensors) and VPN topologies (which are made
up of multiple devices), and then deploying the configurations defined by these policies to these devices.
Several types of policies might be required to configure a particular solution. For example, to configure
a site-to-site VPN, you might need to configure multiple policies, such as IPsec, IKE, GRE, and so forth.
Policies are assigned to one or more devices. After a policy is assigned to a device, any changes to the
policy definition change the behavior of the device.
