PKI Security - CLI

The Public Key Infrastructure (PKI) provides a common set of infrastructure features supporting public key and certificate-based authentication based on the RSA public/private key pairs and X.509 digital certificates.

Certificate Types

Local-Internal Certificates

In previous SBC versions, the RSA key pairs and Certificate Signing Request (CSR) for SBC platforms were generated on an external workstation. The CSR was then submitted to a Certificate Authority, and the resulting certificate was received back from the CA, copied onto the workstation, and combined with the private key in a PKCS#12 file which was used to install the key pair and certificate onto the SBC.

The SBC application can now generate and install RSA key pairs and generate Certificate Signing Request (CSR) on the SBC system itself. The certificate request is sent to a CA, and the issued certificate is then installed on the SBC. The local-internal certificate option simplifies the certificates and keys managing process and also provides more security since the private key never leaves the SBC. For steps to configure local-internal certificates, see Generating PKI Certificates.

Local Certificates

Local certificates are credentials belonging to the local system itself, which it presents to peers in order to prove its identity. You have to download local certificate files to the system before installing the certificates.

Remote Certificates

Remote certificates are credentials belonging to Certificate Authorities (CA). The copies of these certificates are installed in the SBC because they are part of a chain of certificates the local system will present to peers, or because the corresponding CAs are trust anchors for the local system. Certificates belonging to non-CA remote systems should also be installed as trust anchors in this manner.

The Certificate Authority (CA) certificates and trusted remote certificates contain public key certificates; they do not contain the private keys. The CA certificates and remote certificates are Distinguished Encoding Rules (DER) format files; a method for encoding a data object (such as an X.509 certificate) which uses a digital signature to bind together a public key with an identity.

The SBC imports these certificates from Distinguished Encoding Rules (DER) formatted files.
