JUSX-VN-000024 - The Juniper SRX Services Gateway VPN IKE must use NIST FIPS-validated cryptography to implement encryption services for unclassified VPN traffic.

Information

Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The network element must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated.

Solution

The following example commands configure the IKE (phase 1) proposal.

[edit]
set security ike proposal <P1-PROPOSAL> authentication-method rsa-signatures
set security ike proposal p1-proposal dh-group group14
set security ike proposal p1-proposal authentication-algorithm sha-256
set security ike proposal p1-proposal encryption-algorithm aes-256-cbc
set security ike proposal p1-proposal lifetime-seconds 86400
