User Group - Actions tab
The Actions tab is used to control authentication for specific user groups.
Figure 44: User Group, Actions Tab
User/Manager authentication - Rekey is used to change the key of the highlighted user group.
You should change the key regularly to ensure maximum security.
Only SKIP and Preshared Secret IKE VPNs can be manually rekeyed. In the case of SKIP,
rekeying generates and distributes a new master key to all security gateways associated with
the VPN. This SKIP master key is used to generate session keys used for cryptographic
functions. In the case of Preshared Secret IKE VPNs, rekeying generates and distributes a new
negotiation key to all security gateways associated with the VPN. This negotiation key is used to
provide authentication during IKE negotiations, in which the actual session key is dynamically
generated. Manual Keyed VPNs can be rekeyed by manually editing the relevant keys.
