For added security, you can use an HSM to
secure the private keys used in SSL/TLS decryption for:
Forward Proxy—The HSM can store the private key of the Forward
Trust certificate that signs certificates in SSL/TLS forward proxy
operations. The firewall will then send the certificates that it
generates during such operations to the HSM for signing before forwarding
the certificates to the client.
Inbound Inspection—The HSM can store the private keys for
the internal servers for which you are performing SSL/TLS inbound
If you use the DHE or ECDHE key exchange
algorithms to enable perfect forward secrecy (PFS) support for SSL decryption,
you can use an HSM to store the private keys for SSL Inbound Inspection.
You can also use an HSM to store ECDSA keys used for SSL Forward
Proxy or SSL Inbound Inspection decryption.
On the HSM, import or generate the certificate
and private key used in your decryption deployment.
For instructions on importing or generating a certificate
and private key on the HSM, refer to your HSM documentation.
