Description

Unapproved mechanisms that are used for authentication to the cryptographic module are not verified, and therefore cannot be relied upon to provide confidentiality or integrity and DoD data may be compromised. Network elements utilizing encryption are required to use FIPS compliant mechanisms for authenticating to cryptographic modules. FIPS 140-2 is the current standard for validating that mechanisms used to access cryptographic modules utilize authentication that meets DoD requirements.

After configuring the Internet Key Exchange (IKE) gateway and IPsec policy, the following commands configure an IPsec policy, enabling Perfect Forward Secrecy (PFS) using Diffie-Hellman group 14 and associating the IPsec proposal configured in the previous example. set security ipsec policy IPSEC-POLICY perfect-forward-secrecy keys group14 set security ipsec policy IPSEC-POLICY proposals IPSEC-PROPOSAL The following commands define an IPsec VPN using a secure tunnel interface, specifying the IKE gateway information, IPsec policy, and tunnel establishment policy. Alternatively, administrators can configure on-traffic tunnel establishment.
