JUSX-VN-000022 - The Juniper SRX Services Gateway VPN must terminate all network connections associated with a communications session at the end of the session.
Information
Idle TCP sessions can be susceptible to unauthorized access and hijacking attacks. IKE Dead Peer Detection (DPD) is a protocol that verifies the availability of IPsec peer devices by sending encrypted IKE Phase 1 notification payloads to peers.Note: For dynamic (remote access) VPN, the TCP keep-alive for remote access is implemented in the Juniper SRX Firewall STIG.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
For site-to-site VPN, configure an Internet Key Exchange (IKE) gateway that includes DPD parameters such as in the following example.set security ike gateway IKE-PEER ike-policy IKE-POLICY
set security ike gateway IKE-PEER address <Peer IP Address>
set security ike gateway IKE-PEER dead-peer-detection always-send
set security ike gateway IKE-PEER dead-peer-detection interval 10
set security ike gateway IKE-PEER dead-peer-detection threshold 2
set security ike gateway IKE-PEER local-identity inet <IPv4 Address in Certificate>
set security ike gateway IKE-PEER remote-identity inet <IPv4 Address in Remote
Certificate>
set security ike gateway IKE-PEER external-interface <interface name>
set security ike gateway IKE-PEER version v2-only
