Discussion

Use of IKEv2 leverages DoS protections because of improved bandwidth management and leverages more secure encryption algorithms.

Check Content

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.

Show security ike gateway <VPN-GATEWAY>

If IKEv2 is not used for IKE associations, this is a finding.

Fix Text

For site-to-site VPNs, configure the Juniper SRX to use IKEv2 only.
