Requiring Certificates from Internal Connections

To increase security for connections originating from the Firebox SSL VPN Gateway to your internal net- work, you can require the Firebox SSL VPN Gateway to validate SSL server certificates. Previous versions of the Firebox SSL VPN Gateway did not validate the SSL server certificate presented by the Web Inter- face and the Secure Ticket Authority. Validating SSL server certificates is an important security measure as it can help prevent security breaches, such as man-in-the-middle attacks.

The Firebox SSL VPN Gateway requires installing the proper root certificates that are used to sign the server certificates.

To install root certificates,

On the Cluster Config tab, select Administration > Manage Trusted root CA certificates

To require server certificates for internal client connections

On the Global Cluster Policies tab, under SSL Options, select Validate SSL Certificates for Internal Connections.

Wildcard Certificates

The Firebox SSL VPN Gateway supports validation of wildcard certificates for Secure Access Clients. The wildcard certificate has an asterisk (*) in the certificate name. Wildcard certificates can be formatted in one of two ways, such as *.mycompany.com or www*.mycompany.com. When a wildcard certificate is used, clients can choose different Web addresses, such as http://www1.mycompany.com or http://www2.mycompany.com. The use of a wildcard certificate allows several Web sites to be covered by a single certificate.
