Modules for SSL scanning Web filtering SSL scanning 6 The SSL scanning rules call several modules to execute jobs that are related to SSL scanning. This section tells you how to configure these modules. You can configure the following modules: • SSL Scanner — Enables certificate verification and content inspection, which are key jobs in SSL scanning. Typically, there are separate settings for the module when called to verify certificates and when called to inspect content. • SSL Client Context — Handles the sending of a certificate from the appliance to a client. After the initial setup, the module uses a certificate issued by the default root certificate authority (CA) that is implemented on the appliance. For further administration, it is recommended that you create your own root CA, using the options provided with the module settings. • Certificate Chain — Handles the building of a certificate chain. When building the chain, the module uses a list of certificate authorities for the certificates that are included in the chain. You can add certificate authorities to existing lists and also add new lists. Configure a module for SSL scanning This section describes the procedure for configuring the modules that are involved in SSL scanning. To configure an SSL scanning module: 1 Go to Policy | Settings. 2 On the Engines branch of the settings tree, go to the module you want to configure settings for and select these settings. For example, go to SSL Scanner and select Default Certificate Verification. 3 Configure these settings as needed. 4 Click Save Changes. For more information on these settings, see SSL Scanner engine settings, SSL Client Context engine settings, and Certificate Chain engine settings. SSL Scanner engine settings You can configure the SSL Scanner engine settings. These are the settings for the module that the SSL scanning rules call to verify certificates and enable content inspection in SSL-secured communication. Note: These settings can be configured on the Settings tab of the Policy top-level menu. Certificate Verification Without EDH Settings for the SSL Scanner module when it uses a special mode to verify certificates in communication with web servers that do not support the EDH (Ephemeral Diffie-Hellman) method Meaning and usage of these settings are the same as for the Default Certificate Verification settings. For the Server cipher list parameter, the string specified as its value usually differs from the string specified for the default settings. For more information, see Default Certificate Verification.
