CIF (Control Information File) Server The primary component of the ESM Manager and an important part of the ESM information exchange process. The ESM Manager stores data in several files called Control Information Files (CIFs). These files contain information about ESM access, policy runs, messages that can be output by the security modules, agents, policy information, and so on. The CIF Server provides access to these CIFs. When the ESM Enterprise Console or the Command Line Interface (CLI) needs information from a CIF, it communicates with the CIF Server. The CIF Server accesses the CIFs and relays the information back to the ESM Enterprise Console or the CLI.
