The Cisco SNA appliance must be configured to obtain its public key certificates from an appropriate certificate policy through an approved service provider.

For user certificates, each organization obtains certificates from an approved, shared service provider, as required by OMB policy. For federal agencies operating a legacy public key infrastructure cross-certified with the Federal Bridge Certification Authority at medium assurance or higher, this Certification Authority (CA) will suffice.

Determine if the Cisco SNA appliance obtains public key certificates from an appropriate certificate policy through an approved service provider.

Navigate to SNA Dashboard >> Configure >> Central Management >> Inventory >> Actions... >> Edit Configuration >> Appliance Tab >> SSL/TLS Appliance Identity. Review the TLS certificate to determine if it is issued by a DoW CA.

If the Cisco SNA appliance does not obtain its public key certificates from an appropriate certificate policy through an approved service provider, this is a finding.

Navigate to SNA Dashboard >> Configure >> Central Management >> Inventory >> Actions... >> Edit Configuration >> Appliance Tab >> SSL/TLS Appliance Identity >> Update Identity >> Generate CSR. Input RSA Key Length. Download CSR >> Submit CSR to DoW CA >> Click Replace Identity >> Apply Settings.
