The Apex One server maintains expired certificates for agents with expired public keys. For example, agents that have not connected to the server for an extended period of time have expired public keys. When agents reconnect, they associate the expired public key with the expired certificate, allowing them to recognize server-initiated communications. The server then deploys the latest public key to the agents.

When configuring certificates, note the following:

  • For the certificate path, mapped drives and UNC paths are accepted.

  • Choose a strong password and then record it for future reference.

Important:

When using the Authentication Certificate Manager tool, note the following requirements:

  • The user must have administrator privileges

  • The tool can only manage certificates located on the local endpoint

  1. On the Apex One server, open a command prompt and change the directory to <Server installation folder>\PCCSRV\Admin\Utility\CertificateManager.
  2. Issue any of the following commands:

    Command

    Example

    Description

    CertificateManager.exe -c [Backup_Password]

    CertificateManager.exe -c strongpassword

    Generates a new Trend Micro certificate and replaces the existing certificate

    Do this if the existing certificate has expired or if it has been leaked to unauthorized parties.

    CertificateManager.exe -b [Password] [Certificate path]

    Note:

    The certificate is in ZIP format.

    CertificateManager.exe -b strongpassword D:\Test\TrendMicro.zip

    Backs up all Trend Micro certificates issued by the current Apex One server

    Do this to back up the certificate on the Apex One server.

    Note:

    Backing up the Apex One server certificates allows you to use these certificates if you need to reinstall the Apex One server.

    CertificateManager.exe -r [Password] [Certificate path]

    Note:

    The certificate is in ZIP format.

    CertificateManager.exe -r strongpassword D:\Test\TrendMicro.zip

    Restores all Trend Micro certificates on the server

    Do this to restore the certificate on a reinstalled Apex One server.

    CertificateManager.exe -e [Certificate path]

    CertificateManager.exe -e <Agent_installation_folder>\OfcNTCer.dat

    Exports the Security Agent public key associated with the currently used certificate

    Do this if the public key used by agents becomes corrupted. Copy the .dat file to the agent’s root folder, overwriting the existing file.

    Important:

    The file path of the certificate on the Security Agent must be:

    <Agent_installation_folder>\OfcNTCer.dat

    CertificateManager.exe -i [Password] [Certificate path]

    Note:

    The default file name of the certificate is:

    OfcNTCer.pfx

    CertificateManager.exe -i strongpassword D:\Test\OfcNTCer.pfx

    Imports a Trend Micro certificate to the certificate store

    CertificateManager.exe -l [CSV Path]

    CertificateManager.exe -l D:\Test\MismatchedAgentList.csv

    Lists agents (in CSV format) currently using a mismatched certificate
