Description
Use of IKEv2 leverages DoS protections because of improved bandwidth management and leverages more secure encryption algorithms.
ℹ️ Check
Verify only IKEv2 is used for the IKE security configuration on all configured gateways. Use of IKEv1 mitigates the risk to a CAT III finding.

If IKEv2 is not used for IKE associations, this is a finding.
✔️ Fix
For site-to-site VPNs, configure the Juniper SRX to use IKEv2 only.
