Adding SAN Signed Certificates to FortiManager Devices

Overview

TOS requires that all monitored FortiManager devices have a Subject Alternative Name (SAN) signed certificate. Without a SAN signed certificate, SecureTrack will be unable to retrieve dynamic topology information. By default, FortiManager devices do not include a SAN certificate. Therefore, you must add a SAN certificate to each monitored FortiManager device.

Prerequisites

• Certificate (CSR) signed by a Certification Authority (CA).

  • The Host IP and Subject Alternative Name fields must contain the IP or FQDN of the device. If you use a FQDN, you must verify that the reverse DNS lookup matches the FMG IP address.

  • The IP of the device must be resolvable into its DNS A-Record by reverse lookup.

• Key used to generate the certificate.

Both the certificate and key need to be obtained independently from Fortinet
