Managing Security Certificates in Cisco Unified Operating System
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.

Table 5-1 Certificate Names and Descriptions
Name
|
Description
|
tomcat
|
This self-signed root certificate is generated during the installation of the HTTPS server.
|
ipsec
|
This self-signed root certificate is generated during the installation of secure IPSec server connections.
|
cup
|
This self-signed root certificate is generated during the installation of the Cisco Unified Presence server.
|
cup-xmpp
|
This self-signed root certificate is generated during the installation of the Cisco Unified Presence server.
|
cup-xmpp-s2s
|
This self-signed root certificate is generated during the installation of the Cisco Unified Presence server.
Note The trust certificates for cup-xmpp-s2s are stored in cup-xmpp-trust along with the general XMPP trust certificates.
|
Step 5 Select Generate New.
Troubleshooting Tips
Restart the Tomcat web server after you upload or regenerate a Tomcat certificate, in a Cisco Unified Presence cluster.
Uploading a Certificate or a Certificate Trust List
Caution Uploading a new certificate or certificate trust list (CTL) file can affect your system operations.
Before You Begin
•The system does not distribute trust certificates to other cluster nodes automatically. If you need to have the same certificate on more than one node, you must upload the certificate to each node individually.
•To access the Security menu items, you must sign out and sign back in to Cisco Unified Communications Operating System Administration using your Administrator password.
Procedure
Step 1 Sign in to Cisco Unified Communications Operating System Administration.
Step 2 Select Security > Certificate Management.
Step 3 Select Upload Certificate.
Step 4 Select the name of the certificate or CTL from the Certificate Name list.
Step 5 Select the file to upload by completing one or of the following actions:
•Enter the path to the file in the Upload File text box.
•Select Browse and navigate to the file.
•Select Open.
Step 6 Select Upload File to upload the file to the server.
Step 7 Restart the services affected by the new certificate.
Upload a Directory Trust Certificate
This procedure is applicable to Cisco Unified Presence Release 8.0 only.
Before You Begin
If uploading a root or intermediate certificate authority CA, wait 15 minutes for the audit job before adding these certificates to the trust store. Alternatively you can restart the Intercluster Sync Agent to force the audit job to run immediately.
Procedure
Step 1 Sign in to Cisco Unified Communications Operating System Administration.
Step 2 Select Security > Certificate Management.
Step 3 Select Upload Certificate.
Step 4 Select directory-trust from the Certificate Name list.
Step 5 Enter the file to upload in the Upload File field.
Step 6 Select Upload File.
Step 7 Sign into Cisco Unified Serviceability.
Step 8 Select Tools > Control Center - Feature Services.
Step 9 Restart the service Cisco Dirsync.
Step 10 Sign in to the Cisco Unified Communications Operating System CLI as an administrator.
Step 11 Enter the command utils service restart Cisco Tomcat to restart the Tomcat service.
Step 12 After the services have been restarted, you can add the directory agreement for SSL.
Troubleshooting Tips
Upload root Certificate Authority (CA) certificates or intermediate CA certificates only to the trust store (for example, tomcat-trust, ipsec-trust, cup-trust, cup-xmpp-trust). Be aware that any other certificates uploaded to the trust stores may be deleted during an audit process.
Uploading Signed Certificates to Multiple Clusters
Use this procedure when a cluster has intercluster peers and you want to upload signed certificates to those peers.
Procedure
Step 1 Log in to each intercluster peer
Step 2 Select Presence > Inter-Clustering to ensure the server is not reporting any errors.
Step 3 If errors exist, run a force sync to synchronize the Certificates from the peer side.
Step 4 Upload the root and intermediate (if any) CA certificates to the server.
Step 5 Restart the interclustering service on the server to add the CA certificates to the trust store.
Step 6 Upload the signed certificate to the server.
Step 7 Ensure the server and its certificates are synchronized with their peers.
Step 8 Upload signed certificates only to the peers, root and intermediate CA certificates have already been synchronized from the first server.
Configuring Certificate Revocation
You must upload the Online Certificate Status Protocol (OCSP) to tomcat-trust before enabling OCSP.
You can use the OCSP to obtain the revocation status of the certificate. To configure the OCSP, follow this procedure.
Note This feature is only applicable to Cisco Unified Presence Release 8.6(4) and later.
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
|
Action
|
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:
a. Select Security > Certificate Management.
b. Search for the certificate using the Find filters.
c. Select the .PEM file or .DER file link for the certificate.
d. 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 is raised if a certificate is revoked.
Note In Cisco Unified Presence Release 8.6(5) and later, you cannot upload CA-signed leaf certificates as trust certificates to the trust stores.
How to Use Third Party CA Certificates
Cisco Unified Communications 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 Cisco Unified 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 Communications 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.
