Using SSL to Secure Client/Server Connections in Cisco Unity Connection


This chapter contains information on creating a certificate signing request, issuing an SSL certificate (or having it issued by an external certification authority), and installing the certificate on the Cisco Unity Connection server to secure Cisco Personal Communications Assistant (Cisco PCA) and IMAP email client access to Cisco Unity Connection.

The Cisco PCA website provides access to the web tools that users use to manage messages and personal preferences with Unity Connection. Note that IMAP client access to Unity Connection voice messages is a licensed feature.

See the following sections:

Deciding Whether to Install an SSL Certificate to Secure Cisco PCA, Cisco Unity Connection SRSV, and IMAP Email Client Access to Cisco Unity Connection

When you install Cisco Unity Connection, a local self-signed certificate is automatically created and installed to secure communication between the Cisco PCA and Unity Connection, communication between IMAP email clients and Unity Connection, and communication between Unity Connection SRSV and the central Unity Connection server. This means that all the network traffic (including usernames, passwords, other text data, and voice messages) between the Cisco PCA and Unity Connection is automatically encrypted, the network traffic between IMAP email clients and Unity Connection is automatically encrypted if you enable encryption in the IMAP clients, and the network traffic between Unity Connection SRSV and the central Unity Connection server is automatically encrypted. However, if you want to reduce the risk of man-in-the-middle attacks, do the procedures in this chapter.

If you decide to install an SSL certificate, we recommend that you also consider adding the trust certificate of the certification authority to the Trusted Root Store on user workstations. Without the addition, the web browser displays security alerts for users who access the Cisco PCA and for users who access Unity Connection voice messages with some IMAP email clients.

"Managing Security Alerts When Using Self-Signed Certificates with SSL Connections in Cisco Unity Connection"For more information on self-signed certificate, refer to the "Securing Connections in Cisco Unity Connection Survivable Remote Site Voicemail 10.x" chapter of the Complete Reference Guide for Cisco Unity Connection Survivable Remote Site Voicemail (SRSV) guide at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/10x/srsv/guide/10xcucsrsvx.html.

Securing Connection Administration, Cisco PCA, Cisco Unity Connection SRSV, and IMAP Email Client Access to Cisco Unity Connection

Do the following tasks to create and install an SSL server certificate to secure Cisco Unity Connection Administration, Cisco Personal Communications Assistant, Unity Connection SRSV, and IMAP email client access to Cisco Unity Connection:

1. If you are using Microsoft Certificate Services to issue certificates, install Microsoft Certificate Services. For information on installing Microsoft Certificate Services on a server running Windows Server 2003, see the "Installing Microsoft Certificate Services (Windows Server 2003 Only)" section. For information on installing Microsoft Certificate Services on a server running a later version of Windows Server, refer to Microsoft documentation.

If you are using another application to issue certificates, install the application. See the manufacturer documentation for installation instructions. Then skip to Task 2.

If you are using an external certification authority to issue certificates, skip to Task 2.


Note If you already have installed Microsoft Certificate Services or another application that can create certificate signing requests, skip to Task 2.


2. If a Unity Connection cluster is configured, run the set web-security CLI command on both Unity Connection servers in the cluster and assign both servers the same alternate name. The alternate name will automatically be included in the certificate signing request and in the certificate. For information on the set web-security CLI command, see the applicable Command Line Interface Reference Guide for Cisco Unified Communications Solutions at http://www.cisco.com/en/US/products/ps6509/prod_maintenance_guides_list.html.

3. If a Unity Connection cluster is configured, configure a DNS A record that contains the alternate name that you assigned in Task 2. List the publisher server first. This allows all IMAP email applications, Cisco Personal Communications Assistant, and Unity Connection SRSV to access Unity Connection voice messages by using the same Unity Connection server name.

4. Create a certificate signing request. Then download the certificate signing request to the server on which you installed Microsoft Certificate Services or another application that issues certificates, or download the request to a server that you can use to send the certificate signing request to an external CA. Do the "To Create and Download a Certificate Signing Request" procedure.

If a Unity Connection cluster is configured, do this task for both servers in the Unity Connection cluster.

5. If you are using Microsoft Certificate Services to export the root certificate and to issue the server certificate, do the procedure in the "Exporting the Root Certificate and Issuing the Server Certificate (Microsoft Certificate Services Only)" section.

If you are using another application to issue the certificate, see the documentation for the application for information on issuing certificates.

If you are using an external CA to issue the certificate, send the certificate signing request to the external CA. When the external CA returns the certificate, continue with Task 6.

Only PEM-formatted (also known as Base-64 encoded DER) certificates can be uploaded to Unity Connection. The certificate must have a .pem filename extension. If the certificate is not in this format, you can usually convert what you have to PEM format by using freely available utilities like OpenSSL.

If a Unity Connection cluster is configured, do this task for both servers in the Unity Connection cluster.

6. Upload the root certificate and the server certificate to the Unity Connection server. Do the "To Upload the Root and Server Certificates to the Cisco Unity Connection Server" procedure.

If a Unity Connection cluster is configured, do this task for both servers in the Unity Connection cluster.

7. Restart the Unity Connection IMAP Server service so that Unity Connection and the IMAP email clients use the new SSL certificates. Do the "To Restart the Unity Connection IMAP Server Service" procedure.

If a Unity Connection cluster is configured, do this task for both servers in the Unity Connection cluster.

8. To prevent users from seeing a security alert whenever they access Unity Connection by using the Connection Administration, Cisco PCA, or an IMAP email client, do the following tasks on all computers from which users will access Unity Connection:

Import the server certificate that you uploaded to the Unity Connection server in Task 6. into the certificate store. The procedure differs based on the browser or IMAP email client. For more information, see the documentation for the browser or IMAP email client.

Import the server certificate that you uploaded to the Unity Connection server in Task 6. into the Java store. The procedure differs based on the operating system running on the client computer. For more information, see the operating system documentation and the Java Runtime Environment documentation.

Securing Access to Exchange Calendars, Contacts, and Emails

Securing Access to Cisco Unified MeetingPlace

To secure access to MeetingPlace, do the following tasks.

1. Configure SSL for MeetingPlace. For more information, see the "Configuring SSL for the Cisco Unified MeetingPlace Application Server" chapter of the Administration Documentation for Cisco Unified MeetingPlace Release 8.0 at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/prod_maintenance_guides_list.html.

2. Integrate Unity Connection with MeetingPlace. When you configure Unity Connection for the MeetingPlace calendar integration, specify SSL for the security transport.

3. On the Unity Connection server, upload the root certificate of the certification authority from which you got the server certificate that you installed on the MeetingPlace server in Task 1. Note the following:

The root certificate is not the same thing as the certificate that was installed on the MeetingPlace server. The root certificate for the certification authority contains a public key that can be used to verify the authenticity of the certificate uploaded to the MeetingPlace server.

Only PEM-formatted (also known as Base-64 encoded DER) certificates can be uploaded to Unity Connection. The certificate must have a .pem filename extension. If the certificate is not in this format, you can usually convert what you have to PEM format by using freely available utilities like OpenSSL.

The root certificate filename must not contain any spaces.

To Upload the Root Certificate to the Unity Connection Server


Step 1 Sign in to Cisco Unified Operating System Administration by using the administrator account and password.

The administrator account, which you created during Unity Connection installation, is different from the accounts and passwords that you use to sign in to Connection Administration.

Securing Communication Between Unity Connection and Cisco Unity Gateway Servers When Unity Connection Networking Is Configured

Do the following tasks to create and install an SSL server certificate to secure Connection Administration, Cisco Personal Communications Assistant, and IMAP email client access to Cisco Unity Connection:

1. If you are using Microsoft Certificate Services to issue certificates, install Microsoft Certificate Services. For information on installing Microsoft Certificate Services on a server running Windows Server 2003, see the "Installing Microsoft Certificate Services (Windows Server 2003 Only)" section. For information on installing Microsoft Certificate Services on a server running a later version of Windows Server, refer to Microsoft documentation.

If you are using another application to issue certificates, install the application. See the manufacturer documentation for installation instructions. Then skip to Task 2.

If you are using an external certification authority to issue certificates, skip to Task 2.


Note If you already have installed Microsoft Certificate Services or another application that can create certificate signing requests, skip to Task 2.


2. If a Unity Connection cluster is configured for the Unity Connection gateway server, run the set web-security CLI command on both Unity Connection servers in the cluster and assign both servers the same alternate name. The alternate name will automatically be included in the certificate signing request and in the certificate. For information on the set web-security CLI command, see the applicable Command Line Interface Reference Guide for Cisco Unified Communications Solutions at http://www.cisco.com/en/US/products/ps6509/prod_maintenance_guides_list.html.

3. If a Unity Connection cluster is configured for the Unity Connection gateway server, configure a DNS A record that contains the alternate name that you assigned in Task 2. List the publisher server first. This allows Cisco Unity to access Unity Connection voice messages by using the same Unity Connection server name.

4. On the Unity Connection gateway server, create a certificate signing request. Then download the certificate signing request to the server on which you installed Microsoft Certificate Services or another application that issues certificates, or download the request to a server that you can use to send the certificate signing request to an external CA. Do the "To Create and Download a Certificate Signing Request on a Unity Connection Gateway Server" procedure.

If a Unity Connection cluster is configured, do this task for both servers in the Unity Connection cluster.

5. On the Cisco Unity gateway server, create a certificate signing request. Then download the certificate signing request to the server on which you installed Microsoft Certificate Services or another application that issues certificates, or download the request to a server that you can use to send the certificate signing request to an external CA. Do the "To Create and Download a Certificate Signing Request on a Cisco Unity Gateway Server" procedure.

If Cisco Unity failover is configured, do this task for the primary and secondary servers.

6. If you are using Microsoft Certificate Services to export the root certificates and to issue the server certificates, do the procedure in the "Exporting the Root Certificate and Issuing the Server Certificate (Microsoft Certificate Services Only)" section.

If you are using another application to issue the certificate, see the documentation for the application for information on issuing certificates.

If you are using an external CA to issue certificates, send the certificate signing request to the external CA. When the external CA returns the certificates, continue with Task 7.

Only PEM-formatted (also known as Base-64 encoded DER) certificates can be uploaded to Unity Connection. The certificate must have a .pem filename extension. If the certificate is not in this format, you can usually convert what you have to PEM format by using freely available utilities like OpenSSL.

Do this task for the Unity Connection server (both servers if a Unity Connection cluster is configured) and for the Cisco Unity server (both servers if failover is configured).

7. Upload the root certificate and the server certificate to the Unity Connection server. Do the "To Upload the Root and Server Certificates to the Cisco Unity Connection Server" procedure.

If a Unity Connection cluster is configured, do this task for both servers in the Unity Connection cluster.

8. Restart the Unity Connection IMAP Server service so that Unity Connection and the IMAP email clients use the new SSL certificates. Do the "To Restart the Unity Connection IMAP Server Service" procedure.

If a Unity Connection cluster is configured, do this task for both servers in the Unity Connection cluster.

9. Upload the root certificate and the server certificate to the Cisco Unity server. Do the "To Upload the Root and Server Certificates to the Cisco Unity Server" procedure.

If failover is configured, do this task for the primary and secondary servers.
