    7.3.2 Security Configuration Page Use the Security page to configure the security of the OTMC 100. It is possible to activate password protection for accessing the OTMC 100, generate and define authentication certificates for accessing the OTMC 100 via the secure HTTPS protocol and to disable remote configuration of the OTMC 100, for example via the OMICRON Device Browser or the PTP and SNMP management interfaces.
  • Page 63 OTMC 100 does not have a valid certificate. To avoid such messages, it is necessary to provide the OTMC 100 with such a certificate. There are two possible ways: Generating a certificate signed by an accredited certification authority or generating a certificate signed by yourself.
  • Page 64 OTMC 100 Series User Manual can only be eliminated by providing each web browser used to access the OTMC 100 with the digital signature of "your" certification authority. Due to this, generating a self-signed certificate will in most cases not be a feasible solution in practice. We recommend to generate a certificate signed by an accredited certification authority or to accept the "untrusted connection"...
  • Page 65 7.3.2.4 Protocol Restrictions tab Use this tab to increase the security if you are using the OTMC 100 in a network with high security demands.
