IP Security
IP Security (IPSec) is a framework of open standards that provides data
confidentiality, data integrity, and data authentication between participating
peers. IPSec provides these security services at the IP layer; it uses IKE to handle
negotiation of protocols and algorithms based on local policy, and to generate the
encryption and authentication keys to be used by IPSec.
SDM lets you configure IPSec transform sets, rules, and policies.
Use the IPSec tree to go to the IPSec configuration windows that you want to use.
IPSec Policies
This window displays the IPSec policies configured on the router, and the crypto
maps associated with each policy. IPSec policies are used to define VPN
connections. To learn about the relationship between IPSec policies, crypto maps,
and VPN connections, see More about VPN Connections and IPSec Policies.
Icon
If this icon appears next to the IPSec policy, it is read-only, and it cannot
be edited. An IPSec policy may be read-only if it contains commands
that SDM does not support.
