    Creating a Self-Signed Web Certificate (CTPView Server Menu)

    Before you begin, log in to the CTPView server and access the CTPView Configuration Menu. See Accessing the CTPView Server Configuration Menu (CTPView Server Menu).

    To create a self-signed Web certificate:

    1. From the CTPView Configuration Menu, select 9) AAA Functions.

      The AAA functions for CTPView can be viewed and set in the AAA sub-menu of the CLI menu script. Only System Administrators have authorization to view or modify the AAA functions. Configuration of the CTPView AAA functions has three major components:

      • Configuring the global configuration parameters, for example entering the IP addresses of the RADIUS servers you want to use for authentication.
      • Configuring the global configuration parameters, for example entering the IP addresses of the TACACS+ servers you want to use for authentication.
      • Then selecting the options which the various access methods will use. For example, enabling HTTPS – CAC/PKI with OCSP certificate validation.
    2. Select 7) CAC/PKI Configuration.

      This selection enables you to perform CAC/PKI configuration (HTTPS). CTPView is built with a default server certificate installed which is sufficient for testing purposes only. Before deploying the server in a production environment you must obtain and install a server certificate issued by a Trusted Signing CA. If you attempt to access multiple CTPView servers running on CentOS which are still using their default self-signed certificates you may be denied access by your browser because it will detect that multiple servers are presenting certificates with the same serial number. Obtaining and installing a signed server certificate is a simple process. First, you must create a certificate signing request (CSR) for your server which you will present to the Trusted Signing CA you have selected to use. To start, go to the CAC/PKI Configuration menu. The path is menu > AAA Functions > CAC/PKI Configuration.

    3. In the CAC/PKI Menu, select 2) Self-Sign CSR.

      While it is preferred that you have your server CSR signed by a Trusted Signing CA, where that is not possible you may generate a self-signed server certificate using the CTPView_CA issued by Juniper Networks. Note that if you use the CTPView_CA certificate, the self-signed certificate will generate an error in client browsers to the effect that the signing certificate authority is unknown and not trusted. However you will be able to successfully complete the connection. To use the CTPView_CA to sign your CSR select Self-Sign CSR from the CAC/PKI Menu.

      Enter the CSR filename and the utility will create a signed server certificate which you can then import into the certificate database. No additional Chain of Trust certificates are required to use the CTPView_CA. As when creating a CSR, repeating the signing process has no effect on the configuration or operation of the server since a separate process is required to import the certificate. When the Trusted Signing CA sends you the signed server certificate you will need to import it into your server’s certificate database. You will also need to import all of the certificates that make up the Chain of Trust for your new server certificate. These are available from your Trusted Signing CA. Copy all of the certificates into the /tmp directory of the server. They can have any filename and file extension.

    4. Enter answers for each question that is subsequently displayed.

      You are required to enter the Encryption Key Size, Common Name, Organization Name and Country. You may also include any combination of these optional fields: Organizational Unit (3 possible fields), State, and City/Town. The script will generate a random seed to use when creating the CSR by using the timing of keystrokes on your keyboard. The CSR will be a RSA certificate in ASCII format (i.e. plain text), using either 1024 or 2048 bit encryption depending on your choice when creating the CSR. The CSR name will be <Common Name>.csr and is created in the /tmp directory on the server. If you want to change any of the information you entered when creating the CSR simply create a new CSR. Creating a CSR has no effect on the configuration or operation of the server. Send the CSR which you created to your Trusted Signing CA. You may be asked to send the CSR as an email attachment or to paste the CSR into a web form. You can do that by opening the CSR file with a text editor, such as WordPad or VI, then use the copy and paste editing functions to transfer the new certificate request to the web form.

      Note: For Common Name, enter the IP address of the server. Otherwise, your users’ browsers will report a domain name mismatch when users connect to the server.
