Security certificate management

Security certificate management

The operating system security options enable you to manage security certificates in these two ways:

  • Certificate Management—Manages certificates, Certificate Trust Lists (CTL), and Certificate Signing Requests (CSR). You can display, upload, download, delete, and regenerate certificates.
  • Certificate Monitor—Allows you to monitor the expiration dates of the certificates on the server.

              Configure certificate revocation

              You can use the OCSP to obtain the revocation status of the certificate. To configure OCSP, follow this procedure.

              Before You Begin

              You must upload the Online Certificate Status Protocol (OCSP) Responder certificate to tomcat-trust before enabling OCSP.

              Procedure
                Step 1   Navigate to Security > Certificate Revocation

                The Certificate Revocation window displays.

                Step 2   Check the Enable OCSP check box in the Online Certificate Status Protocol Configuration area.
                Step 3   Choose one of the following options:
                Option Description
                Use OCSP URI from Certificate

                Choose this option if the certificate is configured with OCSP URI and is to be used to contact OCSP Responder.

                To verify that there is an OCSP URI in the certificate, complete the following steps:

                1. Select Security > Certificate Management.
                2. Search for the certificate using the Find filters.
                3. Select the .PEM file or .DER file link for the certificate.
                4. In the Certificate Configuration window, ensure that there is an entry for Extension:AuthorityInfoAccessSyntax and that it has an accessLocation URL.
                Use configured OCSP URI

                Choose this option if external or configured URI is used to contact OCSP Responder. Enter the URI of the OCSP Responder, where certificate revocation status is verified, in the OCSP Configured URI field.

                Step 4   Select Save.

                The certificate revocation status check is performed only during upload of a certificate or certificate chain. The appropriate alarm will be raised if a certificate is revoked.


                Third Party CA certificates

                Cisco Unified Operating System supports certificates that a third-party Certificate Authority (CA) issues with PKCS # 10 Certificate Signing Request (CSR).

                To use an application certificate that a third-party CA issues, you must obtain both the signed application certificate and the CA root certificate from the CA. Get information about obtaining these certificates from your CA. The process varies among CAs.

                CAPF and IM and Presence Certificate Signing Requests (CSRs) include extensions that you must include in your request for an application certificate from the CA. If your CA does not support the ExtensionRequest mechanism, you must enable the X.509 extensions that are listed in the final window of the CSR generation process.

                Cisco Unified Operating System generates certificates in DER and PEM encoding formats and generates CSRs in PEM encoding format. It accepts certificates in DER and DER encoding formats.

                Cisco verified third-party certificates that were obtained from Microsoft, Keon, and Verisign CAs. Certificates from other CAs might work but have not been verified.

                Third-party certificate process management

                This procedure provides an overview of the third-party certificate process, with references to each step in sequence:

                For More Information

                Step 1

                Generate a CSR on the server.

                See Generate certificate signing request.

                Step 2

                Download the CSR to your PC.

                See Download certificate signing request.

                Step 3

                Use the CSR to obtain an application certificate from a CA.

                Get information about obtaining application certificates from your CA.

                Step 4

                Obtain the CA root certificate.

                Get information about obtaining a root certificate from your CA.

                Step 5

                Upload the CA root certificate to the server.

                See Upload certificate or certificate trust list.

                Step 6

                Upload the application certificate to the server.

                See Upload certificate or certificate trust list.

                Step 7

                If you updated the certificate for CAPF or IM and Presence, generate a new CTL file.

                See Upload certificate or certificate trust list.

                Step 8

                Restart the services that are affected by the new certificate.

                For all certificate types, restart the corresponding service (for example, restart the Tomcat service if you updated the Tomcat certificate).

                For information about restarting services, see the Cisco Unified Serviceability Administration Guide.
