Cisco Cisco Web Security Appliance S170 Guia Do Utilizador

If you are acquiring a certificate for the first time, search the Internet for “certificate authority services 
SSL server certificates,” and choose the service that best meets the needs of your organization. Follow 
the service’s instructions for obtaining an SSL certificate.

You can also generate and sign your own certificate. Tools for doing this are included with OpenSSL, 
free software from 

http://www.openssl.org

.

In addition to root certificate authority (CA) certificate verification, AsyncOS supports the use of 
intermediate certificate verification. Intermediate certificates are certificates issued by a trusted root CA 
which are then used to create additional certificates. This creates a chained line of trust. For example, a 
certificate may be issued by example.com who, in turn, is granted the rights to issue certificates by a 
trusted root CA. The certificate issued by example.com must be validated against example.com’s private 
key as well as the trusted root CA’s private key.

To upload a digital certificate to the Web Security appliance, use the 

certconfig

 command.

The following example shows a certificate being uploaded. You can also add intermediate certificates 
from this command.
