19.8 Trusted CAs

Click Security > Certificates > Trusted CAs to open the Trusted CAs screen. This screen
displays a summary list of certificates of the certification authorities that you have set the
ZyXEL Device to accept as trusted. The ZyXEL Device accepts any valid certificate signed by
a certification authority on this list as being trustworthy; thus you do not need to import any
certificate that is signed by one of these certification authorities.
