15.1.1 Advantages of Certificates
Certificates offer the following benefits.
• The ZyWALL only has to store the certificates of the certification authorities that you
decide to trust, no matter how many devices you need to authenticate.
• Key distribution is simple and very secure since you can freely distribute public keys and
you never need to transmit private keys.
15.2 Self-signed Certificates
Until public-key infrastructure becomes more mature, it may not be available in some areas.
You can have the ZyWALL act as a certification authority and sign its own certificates.
15.3 Configuration Summary
This section summarizes how to manage certificates on the ZyWALL.
Figure 126 Certificate Configuration Overview
