Certificate Requests
|
Your Action
|
Name
|
Enter the name of the certificate requestor; typically,
this is the person who administrators the security device.
|
Phone
|
Enter the telephone number of the certificate requestor.
|
Domain Component
|
Enter one or more domain components for the certificate
requestor. Multiple entries must be separated by commas.
|
Unit/Department
|
Enter the unit or department of the certificate requestor.
|
Organization
|
Enter the organization of the certificate requestor.
|
County/Locality
|
Enter the county or locality of the certificate requestor.
|
State
|
Enter the state of the certificate requestor.
|
Country
|
Enter the country of the certificate requestor.
|
E-mail
|
Enter the e-mail address of the certificate requestor.
|
IP Address
|
Enter the IP address of the certificate requestor.
|
FQDN
|
Enter the fully qualified domain name of the security
device.
|
Key Pair Type
|
Select RSA or DSA encryption.
|
Key Pair Length
|
Select the key length: 512, 786, 1024, or 2048. Ensure
that your certificate authority can support the key length you select.
Key lengths greater than 1024 might require generation times longer
than 10 minutes.
|
Create Self-Signed Certificate (ScreenOS 5.1 and higher
only)
|
Select this option to use the self-signed certificate
on a device running ScreenOS 5.1 and later. Because the self-signed
certificate is both the local certificate and the CA certificate,
when this option is enabled the SCEP options are automatically disabled.
|
Automatically Enroll
|
Select this option to use SCEP. The device automatically
requests, receives, and installs the local certificate and the CA
certificate locally. To use SCEP, configure the following defaults:
- Certificate authority—Select a preconfigured CA
or use the default CA settings for the device.
- E-mail request to—Provide the e-mail address that
receives the PKCS#10 file, which defines the syntax for certification
requests.
|
Click OK to send the
request prompt to the device.
A Job Manager window appears to display job information and
job progress. When the job is complete, the device public key appears
in the Job window.
If you are obtaining the local certificate manually,
you need the device public key to give to the CA. Copy and paste the
information from the job window to a text file, or leave the job window
open while you contact the CA.
If you are using SCEP to obtain a local certificate
and a CA certificate, the device automatically sends its public key
to the CA directly. When SCEP obtains both the local and CA certificate,
the job completes. Close the Job Manager window, and then check the
status of certificates: open the device configuration and select VPN Settings > Local Certificates. The certificate status appears as active,
indicating that the certificate file has been successfully installed
on both the physical device and the management system (you might need
to use the Refresh directive to prompt the UI to update the certificate
status).
If you are using the self-signed certificate on
a device running ScreenOS 5.1 and later, the device automatically
creates the certificate. A Job Manager window appears to display job
information and job progress. When the job is complete, close the
Job Manager window. To view the certificate, open the device configuration
and select VPN Settings > Local Certificates. The certificate status appears as active,
indicating that the self-signed certificate file has been successfully
created and installed on both the physical device and the management
system.
