Server Authentication Certificate

The Setup program attempts to detect preexisting authentication certificates during installation. If a preexisting certificate exists, Trend Micro Apex One automatically maps the file on the Server Authentication Certificate screen. If no preexisting certificate exists, Trend Micro Apex One defaults to the Generate a new authentication certificate option.

Trend Micro Apex One uses public-key cryptography to authenticate communications that the Trend Micro Apex One server initiates on agents. With public-key cryptography, the server keeps a private key and deploys a public key to all agents. The agents use the public key to verify that incoming communications are server-initiated and valid. The agents respond if the verification is successful.

Trend Micro Apex One can generate the authentication certificate during the installation or administrators can import a preexisting authentication certificate from another Trend Micro Apex One server.
