McAfee ePO On-Premises You need these components to install McAfee Agent on client systems: McAfee ePO extension (EPOAGENTMETA.zip) — A .zip file that is installed on McAfee ePO. Installing McAfee Agent extension allows you to customize product features on McAfee ePO. McAfee Agent software package (MAxxxWIN.zip or MAxxxLNX.zip or MAxxxMAC.zip) — A .zip file that contains product installation files. Once the package is checked in to the Master Repository, McAfee ePO can deploy it to your managed systems. McAfee Agent key updater package (AgentKeyUpdate.zip) — This distributes the new master keys when an update is received from the McAfee ePO managed repositories. McAfee Agent uses agent-server secure communication (ASSC) keys to communicate securely with the server. You can generate new ASSC keys and use them as a master set. Existing agents that use other keys in the agent-server secure communication keys list do not change to the new master key unless there is a client agent key updater task scheduled and run. McAfee Agent key updater package is multi-platform and updates the master public key (srpubkey.bin) and the corresponding request key (reqseckey.bin).
